I just ran into an issue that was cause by me using an outdated version of your library. As the podspec file points to tag 0.1, it will not pick up your latest commits. I managed to work around this issue by pointing CocoaPods to the master branch:

pod 'QMBParallaxScrollViewController', :git => 'https://github.com/quemb/QMBParallaxScrollViewController.git'

But it certainly would helpful to be able to use the podspec file directly.

I have a custom header with two buttons (the first one opens a left-side sliding menu and the other one refreshes the view). I'd like to remove the sliding header and also place the scrolling table underneath because both cover my custom header. Is that possible?

i'm using a UIView containing other 2 sub uiviews and pagecontrol. when i start scrolling down, the topview was not animated. because i guess the topviewcontroller.view was not uiimageview?

However when i set the main view as uiimageview with some image, it was scrolling properly.

Also, I found in the sample project, when you scroll top view to second image, then scrolling the bottomview, the top one was switch back to the first one.

I'm using interface builder with a nib file instead of storyboard. are there any ways i can add cutomized uiview onto the top view and keep the effects? do I need to take a snapshot of the whatever the state of the topview then pass it back to background view to make it work?

Reproduction:

1. Show an image as a top view controller.
2. Display at least of a couple of screenfuls of content. Scroll to the bottom.
3. Flick down to scroll up. Standard scrollview deceleration takes 2-3 seconds to bring the scrolling to a stop.
4. Observe that deceleration is much stronger when the scrollview hits the image; scrolling stops much more abruptly, and usually doesn't reach the top of the image.

Love the control, excellent job.

I have a question, when swiping downwards and the view reaches the top, it quickly takes the Image into Full Screen Mode.

Is it possible to adjust the resistance before Image goes to Full Screen Mode?

Thank you.

Shouldn't parallex be spelled parallax?

I see you expand the UITableView to its full height, so all the cells will be rendered in one time!

That mean we cannot use this super cool effect if we have too many rows (especially with remote images inside) ;-(

Why you didn't use the Scroll of the bottom UITableView (or UICollectionView)?

Hey, I've been working with your library for a couple days now and I really like it so far, it's definitely one of the better ones out there. I have already made quite a few changes to it to fit my needs but I am struggling with getting it to work with an opaque UINavigationBar in the UINavigationController. Do you have any insight about supporting this or be able to point me in the right direction? It appears that when you use an opaque nav bar the "bottom" / "foreground" view becomes aware of it (as though it applies to the foreground view as well) and there is some strange animation that goes on if you try to hide the navigation bar when animating to full screen. If you know where I can look, I'd be happy to develop the functionality myself and submit a pull request.

Thanks!

Is there a way to Remove the Top Parallax View once it is added?

In my case I open up a note record that might have an image or not. If it has the image I would like to add the Parallax View but if the next record does not how would I remove the current added Top Parallax View?

Thank you for a great control.

I made a lot of changes for using this with a client's app that had a mapview with tableview that slides up from the bottom:

• allow the top view, the mapview in my case, to stay fullscreen with the bottom view above it (because resizing map view while panning scrollview looks bad, keeping it fixed size & recentering it while panning looks better)
• allowed automatic setup from storyboard using custom segues to reference top & bottom view controllers, setting the top view controller as the delegate if it conforms to protocol
• allowed setting height, max of bottom view instead of the top view
• allowed setting a snap position, a threshold for snapping to this height or to max or min when panning stops
• had problems with scrollview delegate methods, changed to have the bottom view controller just explicitly forward delegate calls to its parent view controller

I'll put what I have into a simple fork for now, but wondered if you'll be interested in taking these changes as pull requests? If so, I'll need to re-implement some of them to be based on your code as starting point rather than the experimental hack & rewrite I did.

But if some of those changes don't fit with your ideas, then I'd rather rename my fork to avoid confusion and let it live as a new cocoapod for my client's app, from which you or any of your users can back-port any of my work as desired.

Can I get your opinion?

Would it be possible to put the top parallax view on the bottom, or have an option (property flag, maybe) to put it there?

Is it possible to bring the scrollview back to the original position ,programmatically.
Thanks in advance.

I would like to use a UICollectionViewController as a bottomController but it is getting its own scrollbar. Do you have any idea on how to fix that / can you provide an example with a collection view?

I would love to be able to have the top cell in my table view (bottom scroll view) overlap the bottom of the photo. It is partially transparent and I'd like to be able to see it when the top view is not full screen. However I would like for it to animate full off-screen when transitioning to the full screen view. Do you know how I might accomplish this? I can develop myself (I have already attempted) and submit a pull request but I am stuck and I could use some guidance as to where to start.

Thanks!

Not sure what to do about this -- my bottom VC is a tableview. I've tried calling scrollToRowAtIndex from that view controller itself, as well as from its parent QMBParallaxVC. Neither responds.

Any suggestions? BTW, great work on this.

I create everything programmatically on my project, when I try to plugin this plugin to my project, I encounter the issue that the base view cannot change to UIImageView and also cannot resize the UIViewController.

See http://stackoverflow.com/questions/25379152/change-base-view-of-uiviewcontroller-to-uiimageview

Can provide an sample project create everything programmatically?

When QMBParallaxScrollViewController's view frame changes the subviews do not update accordingly.

One solution is to update the foregroundScrollView's frame upon view frame observer change:

if ([keyPath isEqualToString:@"frame"]) [self.foregroundScrollView setFrame:(CGRect){{0,0},self.view.frame.size}];

or set the _foregroundScrollView's auto resizing mask

_foregroundScrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

All the view layouts are messed up when running the sample version in ios 7.1.
