Clash Royale CLAN TAG #URR8PPP How to display 3 cells per row in UICollectionView? I used a custom flow layout according to this post. Here is my implementation: @implementation CustomLayout -(void)prepareLayout{ [super prepareLayout]; // [self invalidateLayout]; if(self.collectionView){ CGSize newItemSize=self.itemSize; // Number of items per row int itemsPerRow=3; float totalSpacing=self.minimumLineSpacing*(itemsPerRow-1); newItemSize.width=(self.collectionView.bounds.size.width -totalSpacing)/itemsPerRow; if(self.itemSize.height>0){ float itemAspectRatio=self.itemSize.width/self.itemSize.height; newItemSize.height=newItemSize.width/itemAspectRatio; } [self setItemSize:newItemSize]; } } @end This is what I've got: What did I miss?

Clash Royale CLAN TAG #URR8PPP Image does not fit properly in collectionCell In Swift 3. My app has a table view and a detail view with is a view controller. Here I added a collection view. An array of images must be presented. The images adapt themselves beautifully if in portrait I check the content mode in scaler to fill. In ladscape it works in aspectFill.

Clash Royale CLAN TAG #URR8PPP UICollectionView with full page cells VS UIScrollView with child view controllers I'm trying to create a ViewController which would have swipe-able (android like tabs) pages. These pages themselves will have scrollviews(vertical) inside them and multiple views which would be added dynamically depending on type of response (different network calls for each page).
