uicollectionview

问题 I'm encountering the same problem as here which is that large UICollectionViewCell (more than twice of UICollectionView height apparently) disappear at a given scrolling offset and then reappear after a given scrolling offset also. I've implemented @JonathanCichon solution which is to subclass UICollectionView and perform custom action on _visibleBounds (I know it's a private API but no matter, i don't need to submit it on Apple Store) Here my custom collection view : #import "CollectionView

问题 How can I change the UICollectionView cell height? As you can see, the text just stops with "...". I want the size to get bigger when the label I bigger, I want the cell size to go below the label. How can I do this? Hope you understand my question.. Anyone please? 回答1: This answer does not change the cell size at all, but it could be a solution to your problem. In your cellForItemAtIndexPath after you set your cell: let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell",

问题 I have a bunch of UITextFields living inside a collection view in different cells (around 7). I'm looking for a way to delegate the responsibility of validating these fields to an internal service class. Is there a way in which I can do this without causing controller bloat? What I've partially tried is to create an object and then assign the Textfield delegates to this object. However I struggled on linking the two together (able to access the textField.text property to validate and add the

问题 I'm still kinda new to this; so be gentle. I want to download a setlist from flickr then select the following set and view its pictures. Sp far I've contracted a way to get setlist.

问题 I'm trying to synchronize scrolling in all collection views within a table view (see image link below) : Example Image : http://postimg.org/image/dduhr89e5/ The sample that I have been able to find explains how you can sync two separate scroll views by identifying each. However I am unsure how to identify each collection view when they are in a table view. There could be 1 or hundreds that all need synchronized. - (void)scrollViewDidScroll:(UIScrollView *)scrollView { if ([scrollView isEqual:
