I used UICollectionView (flowlayout) to build a simple layout.
the width for each cell is set to the width of screen using self.view.frame.width
but when I rotate the device, the cells don't get updated.
I have found a function, which is called upon orientation change :
override func willRotateToInterfaceOrientation(toInterfaceOrientation:
UIInterfaceOrientation, duration: NSTimeInterval) {
//code
}
but I am unable to find a way to update the UICollectionView layout
The main code is here:
class ViewController: UIViewController , UICollectionViewDelegate , UICollectionViewDataSource , UICollectionViewDelegateFlowLayout{
@IBOutlet weak var myCollection: UICollectionView!
var numOfItemsInSecOne: Int!
override func viewDidLoad() {
super.viewDidLoad()
numOfItemsInSecOne = 8
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func willRotateToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {
//print("orientation Changed")
}
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return numOfItemsInSecOne
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cellO", forIndexPath: indexPath)
return cell
}
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize{
let itemSize = CGSize(width: self.view.frame.width, height: 100)
return itemSize
}}
