The cells dont get invisible, they are misplaced out of bounds sometimes on fast scrolling. Now click cell in our left side and got to identity inspector and give class name as new file we created "ImageCollectionViewCell". This seems to be a bug in UICollectionView when using sectionInsets. We cannot simply create an outlet for this UIImage in ViewController file, we will have to create a new file. For creating a new file just press key Command ⌘ + N click cocoa touch class select subclass as UICollectionViewCell, name the file as CollectionViewImageCell and click next and create file, new file is created. Search for UIimage and place that image in CollectionViewCell and set all constraints to zero. Now on right side go to attribute inspector name, I use indentifier as "cell", you can give any name but I gave "cell" here, When we will have to display something or place some content in CollectionViewCell we will be using this identifier name "cell".

It should actually be return UIEdgeInsetsMake (0, 100, 0, 100). Open Xcode and create single view application, name the project and click next and we are ready to go. We can create a custom DataSource object by using UICollectionViewDataSource protocol. Every item in CollectionView is called a cell, as in this example each image of a cat is presented in a cell.ĬollectionView gets data from an object called DataSource that are stored in CollectionView's DataSource property. ![]() We can see in this example where we have a CollectionView that has cat images, these images are structured as grid, we can scroll it down.
