uicollectionviewcell

I have created a custom UICollectionViewCell in Interface Builder, binded views on it to the class, and then when I want to use and set a string to the label on the string, tha label has a nil value. override func viewDidLoad() { super.viewDidLoad() // Register cell classes self.collectionView.registerClass(LeftMenuCollectionViewCell.self, forCellWithReuseIdentifier: "ls") } override func collectionView(collectionView: UICollectionView!, cellForItemAtIndexPath indexPath: NSIndexPath!) -> UICollectionViewCell! { var cell: LeftMenuCollectionViewCell cell = collectionView

What's happening Currently I have an application that uses two UICollectionViews inside a UITableView . This way I create a Pulse News look like application. My problem with this is that sometimes the 6th and 11th row disappears completely, leaving a blank space where it should be the cell. I wouldn't actually mind, if all the cells were like this (and this way I could assume that I wasn't doing things correctly), but the thing is, is just happening with those specific ones. My theory The 6th and 11th rows are the ones that appears when I start scrolling, so by default I am able to see 5 cells

I have a simple UICollectionView with cells that have a single UITextView. The UITextView is constrained to the edges of the cell, so they should stay the same size as the cell size. The problem I'm having is that for some reason these constraints are not working when I specify the cell size via collectionView:layout:sizeForItemAtIndexPath:. I have the cell size set to 320x50 in the Storyboard. If I return a size with 2 times the height of the cell size with sizeForItemAtIndexPath:, the UITextView stays the same height despite the constraints I set. I am using Xcode 6 GM.

I just started learning about UICollectionViews. I'm wondering if anyone knows how to specify the number of columns in a collectionview. The default is set to 3 (iPhone/portrait). I've looked at the documentation and can't seem to find a concise answer. CollectionViews are very powerful, and they come at a price. Lots, and lots of options. As omz said: there are multiple ways you could change the number of columns I'd suggest implementing the <UICollectionViewDelegateFlowLayout> Protocol, giving you access to the following methods in which you can have greater control over the layout of your

I'm trying to use Firebase to set the number of cells in my CollectionView. I tried to create a local variable and set that to the same value as the Firebase variable but when I try use it outside the function it doesn't work. I also tried setting it in ViewWillAppear but it didn't work. I set the nav bar title to view the value. When it was set in the closure I got the correct value, when I wrote that outside the closure (after the firebase function), it gave a value of 0. I'm using swift 3 override func viewWillAppear(_ animated: Bool) { FIRDatabase.database().reference(withPath: "data")
