If you have a lot of section items and drag the whole tableview so that only the last section is visible and attempt to close it crashes.

I've replicated in the example project and in my own project.

FZAccordionTableView.sectionForHeaderView method works wrong for first header. Somehow, [self rectForHeaderInSection:middleSection] in sectionForHeaderView returns a minor floating origin.y for first section. so, when user taps on first header, sectionForHeaderView returns NotFound, and it crashes in app in next line

Thank you for your work on this awesome Accordion. Unfortunately my app crashes in line 216 ( compareHeaderViewFrame = [self rectForHeaderInSection:middleSection];) of FZAccordionTableView.m after trying to close the last Accordion Section. I made the following steps:

• implemented Accordion View containing 4 sections with custom Header Views
• section 4 is containing several cells.
• when scrolling down at first the section headers dissapear and then the actual cells in section 4 beginn to scroll. As soon as only section 4 cells are visible, the app crashes when clicking on section 4 header view to close section 4.
• apart from that, scrolling the last section works fine
• you can close section 4 if you avoided scrolling section 4 before.

I am having trouble understanding how to change the text for the headers. I just see the .xib file of the headers, but in which file and where can I change the header title?

Hi i am using your FZAccordionTableView i am using this with segment control each segment control will show different data. the problem is when i select a section it expands until now its fine but without closing the section if i click on next segment the selected section remains opens for the selected segment as well
i am reloading the table but still can't achieve it .i want it to be closed how can i achieve it
Help would be great
thank you

I have requirement to show/open a child cell when selecting a cell. Is it possible to implement with this library ?

Setting the background color on UITableViewHeaderFooterView has been deprecated. Please use contentView.backgroundColor instead.

I want to close all the opened sections?

The problem happens when I tap a section and, while the animation is still running, quick tap another section.

lldb message:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '-[FZAccordionTableView _contentOffsetForScrollingToRowAtIndexPath:atScrollPosition:]: row (0) beyond bounds (0) for section (1).'

The table view is configured as follows:

self.tableView.allowMultipleSectionsOpen = NO;
self.tableView.enableAnimationFix = YES;
self.tableView.rowHeight = UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight = 124;

Couldn't find requirements in the description.

Thanks for the help

This seems to be not working how to implement can you help me sorry for troubling as am fresher

(void)tableView:(FZAccordionTableView *)tableView willOpenSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header
{
AccordionHeaderView *headerView = [tableView dequeueReusableHeaderFooterViewWithIdentifier:kAccordionHeaderViewReuseIdentifier];
headerView.titleLabel.text=@"hi";
}

(void)tableView:(FZAccordionTableView *)tableView didOpenSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header
{
AccordionHeaderView *headerView = [tableView dequeueReusableHeaderFooterViewWithIdentifier:kAccordionHeaderViewReuseIdentifier];
headerView.titleLabel.text=@"hi";
}

Hi,
Thanks for making such great flexible library. we are looking for pure swift version of "FZAccordionTableView.swift" rather than using bridge header.

Do you have any plans for converting this from objective C to Swift ?

Thanks

When i dont want to use delegate of tableview which sets height of section height, there is a problem about refresh issue. After several touches on sections, cell of related section is breaking down(ui problem). i guess it is about layoutifneeded after expand the section

Hi,

Would kindly like to request for help regards to opening of sections. I have 5 sections and randomly the 3rd section isnt sensitive at times. I need to tap below the section view in order to open it. Do you have any advise for this?

Thanks again for this great library !

When the header section collapsed, the viewAssignment will be hidden
When the header section expended, the viewAssignment view will show. Where do I config that.

func tableView(_ tableView: FZAccordionTableView, willOpenSection section: Int, withHeader header: UITableViewHeaderFooterView?) {
        let cell = tableView.dequeueReusableHeaderFooterView(withIdentifier: ReviewHeader.kAccordionHeaderViewReuseIdentifier) as! ReviewHeader
        cell.viewAssignment.isHidden = false
    }

    func tableView(_ tableView: FZAccordionTableView, willCloseSection section: Int, withHeader header: UITableViewHeaderFooterView?) {
        let cell = tableView.dequeueReusableHeaderFooterView(withIdentifier: ReviewHeader.kAccordionHeaderViewReuseIdentifier) as! ReviewHeader
        cell.viewAssignment.isHidden = true
    }

Thank a

Hi Sorry to disturb you again i have placed a imageview in the headerView i want to show different images when section is opened and closed.But it seems to be not happening any help would be great
here is my code
and that too i want to change only the current expanded section

• (void)tableView:(FZAccordionTableView *)tableView didOpenSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header
  {
  headerViewC.arrowImageView.image=[UIImage imageNamed:@"CollapseArrow.png"];
  [tableViewAccord addSubview:segmentedControl1];
  NSLog(@"OPENED");
  }

• (void)tableView:(FZAccordionTableView *)tableView didCloseSection:(NSInteger)section withHeader:(UITableViewHeaderFooterView *)header
  {

  headerViewC.arrowImageView.image=[UIImage imageNamed:@"ExpandArrow.png"];
  [tableViewAccord shouldPositionParallaxHeader];
  NSLog(@"CLOSED");

}

Hello Sir,

When i delete row from table and set multiple section open properties off .When i select any header app becomes crash.

Thanks and Regards

I created different tableviewcell XIB files for each section. When i open cell in order like 2,1,0(index) , everything works as expected. But when i expand 0 index cell, scroll to the end tap into 1 index. Part of 1 index cell shows under header. To be clear, my header is not transparent.

How can i solve it? or is this a bug?

How can we disable all animations open/close from your lib?

Hello,

First thanks for create this, currently I'm using your pod and I have to implement certain functionality after the user scroll up or down the table view, so I was trying to use the following UIScrollDelegate methods in my view controller (which contains a FZAccordionTableView):

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset NS_AVAILABLE_IOS(5_0);
// called on finger up if the user dragged. decelerate is true if it will continue moving afterwards
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate;
- (void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView;

Basically they never get called, in order to fix this (the first method for example) I added this method inside your class FZAccordionTableView.m:
- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset { [self.subclassDelegate scrollViewWillEndDragging:scrollView withVelocity:velocity targetContentOffset:targetContentOffset]; }
In summary looks like FZAccordionTableView is not propagating the UIScrollDelegate methods.

as shown in picture the header cell not take all the width and stay with 320 px , how can i make it dynamic ?
because if i change in xib the size it will not fit in other devices

thanks

I have used table view controller instead of uiviewcontroller (as in your sample code). It was working perfectly until it started to crash randomly when tapping on header for opening section. Sometimes it is crashing for specific record and sometimes it is not that predictable. Any thoughts?

Hi Kris Gaidis thank for your FZAccordionTableView guide it worked for me a great.But i have one small doubt How to show different names in section header Label for different sections.
for example:-on first section header it should be "FIRST"
on second it Should be "Second"
can you please post the anwer

Hi, is there any way to have nested accordions??

Hi,
I got this error and I can't figure out why ?
Can you explain me what does it means ? I followed your example in my code.

Thank you

I've modified your example header view background and add transparency to it. Please take a look at the screenshot bellow.

Cells goes bellow section headers and there for you see such an ugly result.

Crashing after updating to latest version 0.2.2

Can this be because of the following line?

tableView.tableFooterView = UIView()

I am seeing a glitch with the animations of cells as sections are opened and closed. I've noticed you haven't committed anything to this framework for a while, so I am wondering if this may have anything to do with iOS 10.3 >

UPDATE: I can see the issue. The cells are appearing and disappearing above the section header view.

I want to new functionality add for Tableview all section expand when click on outer tableview button and again click then collapse all section. I need to these functionality any one help me.

Any one help me for Tableview Header Text Color change and content view Background color change when collapse and expanding header time, means open section or close section time.

I've successfully implemented a few FZAccordionTableViews in our App, but we've come up with the need to add a second "level".

That is, what we're looking to accomplish is:

HEADER (expandable)
--- SUB HEADER (expandable)
-------- ROW (non-expandable)

Is this a feature/functionality that could possibly be added ?
If anyone has any ideas/pointers, I'd be happy to implement the solution myself, but I'm at a bit of a loss as to where to start.

After opening any section in the tableview, selecting a cell in the subsection is not responsive at first time. Then, all cells are mixed up and they all point at wrong indexpath.row

To reproduce:
Add the didDeselectRowAtIndexPath delegate function in the firstviewcontroller.m file in the example provided

• (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {

  NSLog(@"%d", indexPath.row);
  }

Any solution to that issue?!

I have an uparrow and downarrow image to show in the header. When i open a section, up arrow is correctly getting changed, but when i scroll the tableview i can see the second section image is also getting changed any without selection. How to fix this?

The separator for the tableview sections becomes invisible when a section above is expanded.
If I collapse/expand section 1 the separator between section 1 & section 2 goes away. To get the separator back I have to expand section 2.

Error when expand cell with footer and collpase, the footer is hiding.

Some times Touch on header view is not recognised. and it is mostly occurring when your header view is released from memory.
Steps to Reproduce

1. First reload the tableview
2. All section were closed for the first time
3. Then try to scroll up until top 3 headers disappears and then release the scroll
4. then tap on header view.
5. no action will be received.

I guess there is problem with tap gesture delegate.

how to manually close all the section??

FZAccordionTableViewHeaderView should implement the following constructor when header is not initialised with nib.

- (id)initWithReuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithReuseIdentifier:reuseIdentifier];
    if (self) {
        [self addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(touchedHeaderView:)]];
    }
    return self;
}

I want to collapse all sections when I reload data.
When I reload data, expanded section still remain.
Please help me if you have any suggestion.

I want to make the table expandable to its full size with every change. To do this, I increase the altitude constant for each launch of WillOpenSection and reduce it in WillCloseSection. But Lower cells hide themselves while animation. Is there are any way to fix this? Thanx for help.
