I'm trying to do an animation similar to this on in a UITableView.The slide in animation would be pretty straightforward by modifying the constraints of the content or maybe the transform of the cell using CATransform3D.
The main problem here is, how can I merge two views by simultaneously modifying the cornerRadius of both the view as one view is moving into the screen such that both views appear to be merged(Like in the GIF below). So, my question is,
Is it possible to create an animation where the content of two UITableViewCell can be merged like in the GIF below.
If that isn't possible, how can this animation be done on two UIView which aren't in a UITableView. I might be able to figure out a workaround if I know how to do this animation on two simple UIView.
I've been trying to search and figure out a way to do this for quite sometime but I have no clue on how to do this. Any help or pointers on how to go about to solve this problem will be much appreciated. Thanks!

First of all, apologies if this question isn't meant here. I searched a lot but didn't find anything.
What is the best approach to create a vertical timeline kind of view?
I tried implementing via UITableView by alternating cells but that approach is very messy in terms of autolayouting (had to disbale autolayout and apply programtically when creating cell on alternate side), thereofre isn't working properly (getting stuck while scrolling). This is what I achieved:
I want to achieve something like this, which is also easily manageble:
Please Suggest. Thanks!
I would have 1 cell row with two image views. One on the left, one on the right. I think this would be easier to use auto layout.
Then you can hide the image view and labels that shouldn't be used.
I'm playing around with UICollectionView interactive transitions.
The very basic implementation is here.
Now I'm a bit stuck with Cells transitioning.
The idea is to change content of cells simultaneously with interactive layout transition.
Here is how it looks now.
The first layout
And the second layout
When transitioning is finished, I want to change content of cells on second layout.
1) Text label "Some label" should disappear from every cells
2) Text label "Another label" should appear on the right corner of each cell.
Key issue is I want this changes fade in/out according to UICollectionViewTransitionLayout.transitionProgress value during transitioning.
Something very similar implemented in Facebook Paper App.
Take look how content of cells is changing below (click on it).
Is anybody know an elegant way to replicate this effect?
This library will help you achieve what you are trying. If you are interested in custom animations I would suggest you use FB pop library
Well.
The solution is to subclass UICollectionViewCell.
Subclass should contain two UIView. One for big layout & one for small.
Initially UICollectionViewCell shows only small one.
Once we starting to update UICollectionViewTransitionLayout.transitionProgress for example from small to big we should do following steps:
Make an UIImage from big UIView
Put this image above small UIView
Set alpha of the image to 0
Continuously change alpha of UIImage to UICollectionViewTransitionLayout.transitionProgress value
Once transition is done just switch this to UIView
When you transitioning back you should switch big with small.
Done :-)
I've been searching through here and googling like crazy for a possible solution to this problem. Thus far I'm turning up exactly nothing that actually fixes it so I'm hoping someone can help.
I'm working on the UI for a iPad app. I'm doing it using interface builder. I worked with storyboards briefly but I don't like them all that much so I'm sticking with IB for now. Unfortunately I'm not very experienced with the workings of IOS Ui but it's been going relatively smoothly so far. In my app, I have a view controller, which holds a view containing a pair of sub views. One subview contains a rather windows like header bar (i like the look). The second contains a UITableView. The UITableView is set up properly as far as I can tell, and feeds it's info from a data source using custom UITableViewCells. The UITableView is set to grouped though currently there is only one section. The table is in edit mode by default because I want the user to be able to add new items and use the VC as a selection dialog. The view controller is presented (rather than pushed) using UIModalPresentationFormSheet (again, because I like the view) but I don't know that has any bearing on the problem. The cell border is flush with the X origin, the only reason the text isn't currently starting there is because I went into my cell and move the label over, leaving a gap between the edge of the cell and the label containing my text.
The Offending View http://bit.ly/144cbjT
The Problem: The UITableViewCells, for some reason are positioning themselves at X: 0. This puts them outside the border drawn on the UITablewView when you set it to grouped style. I could probably just turn off the border and get away with it, but I like the look so i want to keep it. I've tried messing around with constraints and anchor points on the cells, the content of the cells, the table itself, the view... I've tried simply moving my cell's labels over a bit. I've also had clipping subviews turned on and off. I've made sure the controls are being loaded properly from the XIB. I've made sure everything is added as a subview where needed. I've made sure I've tried everything I could think of short of setting the cell's X position in code. But since I'm not sure how to tell where the border is, I'd rather have the tableview or the cell do the work itself.
The question: How do I fix this? The selection accessory should be outside the grouping box. The text should be inside, not bleeding out onto the background like it is.I believe the content of the cell should be displayed inside the border within the yellow area.
The odd thing is, this is my fifth or sixth table in this app and I've been doing them all basically the same. Thus far this is the only one I've had trouble with.
Can anyone shed some light as to what's going on?
Thanks in advance
I think that to get this in code, you'd have to do something explicit, so the most likely candidate is a messed up IB file.
Since it doesn't cost anything, I'd just delete the tableView from the IB and then re-add it. If that doesn't work, try recreating the complete IB.
Hope that helps
Perhaps it's something with Xcode 4.5+ or iOS 6 that makes my research fruitless so far, but...
Apple's own advice hasn't worked for me. I set the contentSize to something different, and it causes no changes.
I found this wasn't unique to me, but the answer in that question 1.) does not inform me about the problem and 2.) I'm left wondering if it's really impossible to create a simple, non-inheriting example of UIScrollView. Thus, this question.
A better answer's code was tried within viewDidLoad and viewDidAppear, but to no avail.
So what gives? Is it possible to create a simple, image-filled view that allows scrolling? Say... something as easy as this basic project I set up on github -- but working?
Create and initialize a UIScrollView
Add it as subview to the view of viewcontroller
Make an array of image names
In a loop create UIImageView and add the images and add imageviews into scrollview considering the width of images, set the frame of imageviews
Number of images is known and the width it consumes can be calulated from the loop itself use it to set the contentSize of the scrollview
I would like to make two UIViews. One of them will be fixed in the background with less opacity and the other above will be scrollable. Can I do this?
Yes you can do that. Its quite simple to do that implementation. You create 2 UIView's in the NIB file, one above the other ( in an hierarchy point of view). YOu can set the opacity of the one above, so you can see the one behind. Then, just drop an UIScrollView in the front one. If you need more help with specifics just reply. :)
