Thanks for fixing the previous issue so quickly! Here is another one...

In GrowingTextView-Example, Example2.viewDidLoad(), add this line:
textView.textContainerInset = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)

See the first screen shot for the result. The placeholder text is closer to the top than bottom, it is expected to be centered.

The second screenshot shows the results after typing text until the line wraps, then backspacing to clear all text. The placeholder location is correct.

I have tried it with the controller where it is below a table view. Upon showing keyboard it pushes the table view behind the navbar by some offset and you cannot scroll to that area.

Not working if I set isScrollEnabled = false

Built directly on top of example storyboard, example 1 runs fine, but both 2 & 3 failed.

Both would complain of height constraints missing. Yet after resolving conflicts by adding missing constraints, textView wouldn't grow as expected. Wondering whether we need to do something more for iOS 11.

i temp change here,and it seems work:

// Limit the length of text
func textDidChange(notification: NSNotification) {
    if notification.object === self {
        if maxLength > 0 && text.characters.count > maxLength {
            let endIndex = text.startIndex.advancedBy(maxLength)
            text = text.substringToIndex(endIndex)
            undoManager?.removeAllActions()
        }
        setNeedsLayout() //For Xcode 8,works
    }
}

I want to add attributed placeholder to textView which if type GrowingTextView. But it shows error "Ambiguous use of "attributedPlaceholder".

I guess the name of the placeholder attribute should be changed to something different as UItextView already has placeholder attribute.

I have an error in my objective-c project:
GrowingTextViewDelegate can't be found.

Hello,

I tried with GrowingTextView examples and working as expected, but if try by creating a new project with Xcode 9.3 and i apply same constraint giving an error Input Toolbar (need constraint for: Y position or Height).

Please have a look on it. Appreciate your work.
Thanks,
Narendra.

Hi
I put it in inputAccessoryView
When I change line by return key
It is not animating as UICollectionView animate

And one more thing, I run the demo App
see below screen
TextView size is not as expected
iOS version = 10.3.2
Device = iPhone 6 Plus

Kindly help me
Thanks

Hey,

First of all, many many thanks for your contribution to this pod. It works amazing ;)

I have a case, when I need to EDIT account description, so in edit case, I have to fill description, but it overrides placeholder text.

Any idea how to solve this?

//>> Set textview properties
txvBio.maxLength = 250
txvBio.placeHolder = "Short bio (up to 250 characters)"

if isEditingAccount {
self.txvBio.text = curAccount.descriptionDetails
}

If self.txvBio.placeHolder = nil then when delete all text, placeholder no longer appear.

Any ideas ?

Thanks in advance!

Hello, thanks for the great library!

I'm trying to use it inside UITableViewCell with all edges pinned to edges of cell, so tableviewcell should grow height with textview size change.
I've adopted self sizing textview, as described here
http://candycode.io/self-sizing-uitextview-in-a-uitableview-using-auto-layout-like-reminders-app/

While it works fine with regular UITextView, when I change it to GrowingTextView - I constantly receive following error with constraints (it seems GrowingTextView tries to update height costraint before it should do so):

[LayoutConstraints] Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it.

Hi there

Just noticed that your code do not support paste image to input field is used in messaging app.
Like in whatsapp copy image from any place (check in iphone) and try long press on input field of any chat screen, paste option will appear and on selecting that.. it will allow you to paste, image copied will be shown in other view..

for such handling in you code i modified the class ""

added two new delegates and two methods

Delegates:

@objc optional func textViewPasteImage(_ pastedImage:UIImage)
   @objc optional func textViewPasteText(_ pastedText:String)

methods

override open func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        
        if (action == #selector(paste(_:))) {
            return true
        }
        else if self.text.characters.count > 0 {
            if (action == #selector(select(_:)) || action == #selector(selectAll(_:)) || action == #selector(cut(_:)))
            {
                return true
            }
        }
        
        return false
    }
    
    override open func paste(_ sender: Any?) {
        //
        if (UIPasteboard.general.string != nil) {
            
            if let delegate = delegate as? GrowingTextViewDelegate {
                delegate.textViewPasteText!(UIPasteboard.general.string!)
            }
        }
        else if UIPasteboard.general.image != nil {
            
            if let delegate = delegate as? GrowingTextViewDelegate {
                    delegate.textViewPasteImage!(UIPasteboard.general.image!)
            }
        }
    }

These might not be a perfect solution.... i request please can you add such type for handling
to you code also...

i set it as a GrowingTextView but the height is not changing dynamically textview just has the default function....

I have a table view and each cell has a UITextView. After I changed the UITextView to GrowingTextView, I got this exception when I have several cells in the table:

Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 6 beyond bounds [0 .. 5]'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException

The first throw call stack is not very helpful because it doesn't specify which line of code is causing the issue. But I don't have this exception under the same circumstances if I just use the native UITextView.

make the pod file for swift 3.3 version

I just installed via CocoaPods and when I open .xcworkspace I get the following error:

.../Base.lproj/Main.storyboard: error: IB Designables: Failed to render and update auto layout status for TaskListTableViewController (Ywj-qX-LYh): dlopen(GrowingTextView.framework, 1): no suitable image found.  Did find:
	GrowingTextView.framework: required code signature missing for 'GrowingTextView.framework'

I am unable to proceed.

If you press the backspace quickly and continuously, there are bugs that temporarily do not change the vertical size. Can you fix the problem? Thank you.

I have app crashed by using this library, the reason is "Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)". If there is any body have same issue please let me know how to resolved this issue, thanks

I want to assign an attributedPlaceholder to growingTextView (here : replyTextView) but it keeps on giving the error :
"Ambiguous use of 'attributedPlaceholder".
`if let userName = UserDefaults.standard.value(forKey: "username") as? String {
let text = "Hi (userName) start posting your opinion here."

        let attrStringOfContent : NSMutableAttributedString = NSMutableAttributedString(string: text)

        let rangeOfContent = (text as NSString).range(of: userName, options: .caseInsensitive)

        attrStringOfContent.addAttribute(NSAttributedString.Key.foregroundColor, value: UIColor(hex:  "4A5667"), range: rangeOfContent)

attrStringOfContent.addAttribute(NSAttributedString.Key.font, value: UIFont.boldSystemFont(ofSize: 16), range: rangeOfContent)

        replyTextView.attributedPlaceholder = attrStringOfContent
        }`

Thanks for this great library - would be awesome to add SPM support!

When I update pod with pod 'GrowingTextView', '~> 0.6' it gives me error like below.

How to fix this?
Thanks in advance.

Using the sample app, when the GrowingTextView expands from one line to two lines, there is way too much padding underneath the text, and way too little above it. If you keep typing and expand to three lines, the padding is still off, but not as badly. What is really interesting though is that if you backspace back to two lines, the padding is perfect. See attached screenshots.

My initial thought was that this had to do with the UITextView.textContainerInset, or setting the scroll position. However, if you use Xcode to Debug View Hierarchy you can see what is going on. The TextView has a subview of type _UITextContainerView, and that is obviously offset by about 10 pixels above where it should be. However, using the inspector, that view claims that its frame is at 0,0.

Unfortunately I have no idea how to fix this -- it seems like an iOS bug. I am seeing it building with Xcode 9 on iOS 11 and iOS 10 devices.

My TextView is Feedback/comment enter some text after scrollview not seen Properly I think so after maxHeight it scroll automatically.

Placeholder text is not wrapping if text is longer than control width.

Code looks like this:

import UIKit
import GrowingTextView

class CommentsViewController: UIViewController {
    @IBOutlet var commentTextView: GrowingTextView!
    
    // MARK:- View lifecycle
    override func viewDidLoad() {
        super.viewDidLoad()
        
        customizeCommentTextView()
    }
    
    func customizeCommentTextView() {
        commentTextView.maxLength = 255
        commentTextView.trimWhiteSpaceWhenEndEditing = true
        commentTextView.minHeight = 40.0
        commentTextView.delegate = self
    }
}

when trying to run any of the lines inside customizeCommentTextView() it gives me Thread 1: EXC_BAD_ACCESS (code=257, address=0x1d4474082).

Any idea what might be happening? I followed the README instructions for Storyboard usage and I am using Carthage 0.29.0 to install GrowingTextView 0.5.

Thanks!

It's mentioned in Readme.md file that for Swift 5 you need to use 0.7 version. But if i use that version. It's settings still shows Swift 4 as language and compiler throws error that Swift 5 conversion is available

Hello,

First off, awesome class. I've been finding it very useful.

I had a question about subclassing. I am having a hard time figuring out how to subclass GrowingTextView. The designated initializer is to init?(coder aDecoder: NSCoder) but I'm not using the class within a xib.

I was thinking that perhaps you could make commonInit a public class and that could be overwritten. Otherwise I'm not sure if there is a way to subclass without using a coder. Any suggestions would be appreciated.

Thanks!

If you add a scroll view into the view and set the keyboard dismissal behavior to interactive, when you drag down starting above the toolbar containing the text view, it remains fixed in place while the keyboard is pulled down interactively.

I change this code and reemplace this

` @objc func textDidChange(notification: Notification) {
if let sender = notification.object as? GrowingTextView, sender == self {
if maxLength > 0 && text.count > maxLength {
let endIndex = text.index(text.startIndex, offsetBy: maxLength)
text = String(text[..<endIndex])
undoManager?.removeAllActions()
}

     -->     setNeedsLayout() /// with this line work
   --->   //  setNeedsDisplay() // remove this line
    }
}`

This function should not scroll to the end or to the top. It should scroll to the cursor position.

I added a workaround for myself:

func textViewDidChangeHeight(_ textView: GrowingTextView, height: CGFloat) {
    UIView.setAnimationsEnabled(false)
    let caret = tableView.convert(textView.caretRect(for: textView.selectedTextRange!.start), from: textView)
    let keyboardTopBorder = textView.bounds.size.height - tableView.frame.width
    if caret.origin.y > keyboardTopBorder && textView.isFirstResponder {
        tableView.scrollRectToVisible(caret, animated: true)
    }
    UIView.setAnimationsEnabled(true)
}

error: IB Designables: Failed to render and update auto layout status for UIView (i5M-Pr-FkT): dlopen(GrowingTextView.framework, 1): no suitable image found. Did find:
GrowingTextView.framework: required code signature missing for 'GrowingTextView.framework'

getting this error for days and nothing could fix it , any idea ?

Having an issue when wanting to adjust the inset of the text. I'd like to add a padding to the inside so the text starts further away from the edge of the text view. Currently the text indicator is too close to edge.

Current

Trying to change the content inset gives this outcome:

messageField.textContainerInset = UIEdgeInsets(top: 0, left: 0.5, bottom: 0, right: 0)

Ideas?

In my case, I have chat screen which supports arabic and english language and when I am using your lib, it doesn't showing globe button to change keyboard. Is there some settings to change? Also can't paste arabic or emoji in textview.

I have some sample code below where I try to mimic the dynamic text view calculation like your code. My question is how is the top inset addressed with respect to the text container? When I get to about the second line, my first line shifts up pretty much to very edge of the top frame of Text View. I want the text to stay center to the line height.

import UIKit

class ViewController: UIViewController, UITextViewDelegate {

    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.textView.delegate = self
        self.textView.backgroundColor = .lightGray
    }
    
    func textViewDidChange(_ textView: UITextView) {
        self.calculateSize()
    }

    func calculateSize() {
        let fixedWidth = textView.frame.size.width
        textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
        let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
        var newFrame = textView.frame
        newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
        textView.frame = newFrame
    }
}

I've been using your library for years without problems. Recently I had to resume a project which I haven't touched in several months, so I'm not sure if this is now an iOS 13.3 issue or what, but the textview would just not work.

Until I went into the soucecode of the GrowingTextView and added setNeedsLayout here:

    // Limit the length of text
    @objc func textDidChange(notification: Notification) {
        if let sender = notification.object as? GrowingTextView, sender == self {
            if maxLength > 0 && text.count > maxLength {
                let endIndex = text.index(text.startIndex, offsetBy: maxLength)
                text = String(text[..<endIndex])
                undoManager?.removeAllActions()
            }
            setNeedsDisplay()
            setNeedsLayout() <-- HERE
        }
    }

Then everything works as expected. Is this normal? If not, why could it be happening?

If you don't define the textViewDidChangeHeight "optional" method from the delegate, it crashes. So i don't actually need that method from the delegate. So for now, i'm calling the method, but leave it empty.

Just copied the source into my project, dropped a textview onto my viewcontroller, changed the class to GrowingTextView and when I run, the keyboard overlays the textview?

So in my case I have a tableview and want to add this at the bottom. I created a view, dropped a textview in it (just as in the example 2). What I don't understand is how this resizes the tableview while the keyboard is open?

Hello,

When we have navigationController?.navigationBar.isTranslucent = false
The keyboard is shown over the textView, textView does not appear for the user to type

Any hint for that?
Thanks

Hey @KennethTsang

I use in the same screen 2 textviews.
Is there a way to check which textview is changing height ?

Thanks

Hi @KennethTsang! 😄 First off, great job with this library! As the title suggests, I am suggesting that when the maxHeight is updated, that layoutSubviews be called immediately to update the heightConstraint. For my use case, I am working on something where the maxHeight of the text view is constantly changing depending on certain factors within my app.

Line 100 in GrowingTextView.swift will need to be removed because even though the text and width may be the same, the maxHeight may not be.

Let me know what you think! 👍

Hi, thanks for good work.
But... bug:
just enter fast some lines like this:
http://joxi.ru/DrlBkR0i4bW4j2

layoutSubviews infinite calls, CPU usage 100%
