What I have done is set the label to resize using label.sizeToFit() which is convenient, however I now need to set the cell to properly adjust its size too.
I used the sizeForIndexPath method from the FlowLayoutDelegate to set the cell size to:
messages[indexPath.row].sizeWithAttributes(nil)
however that gives me very thin/small CGSize's.
import UIKit
let reuseIdentifier = "Cell"
class PhotoCollectionViewController: UICollectionViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {
var messages = NSString[]()
override func viewDidLoad() {
super.viewDidLoad()
messages = ["Hello, How are you?", "Ldsfsd sdf dsfs s fs fs", "fsdfsdfsdfs fsdfsdfsdf sfs fs", "yoyo yoy oyo", "sdfd sfds fssfs"]
self.collectionView.registerClass(TextCollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)
self.collectionView.dataSource = self
self.collectionView.delegate = self
self.collectionView.collectionViewLayout = PhotoCollectionViewFlowLayout()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// #pragma mark UICollectionViewDataSource
override func numberOfSectionsInCollectionView(collectionView: UICollectionView?) -> Int {
return 1
}
override func collectionView(collectionView: UICollectionView?, numberOfItemsInSection section: Int) -> Int {
//#warning Incomplete method implementation -- Return the number of items in the section
return messages.count
}
override func collectionView(collectionView: UICollectionView?, cellForItemAtIndexPath indexPath: NSIndexPath?) -> UICollectionViewCell? {
let cell = collectionView?.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as TextCollectionViewCell
cell.backgroundColor = UIColor.lightGrayColor()
cell.newLabel.text = messages[indexPath!.row]
cell.newLabel.sizeToFit()
return cell
}
func collectionView(collectionView: UICollectionView!, layout collectionViewLayout: UICollectionViewLayout!, sizeForItemAtIndexPath indexPath: NSIndexPath!) -> CGSize {
//println(messages[indexPath.row].sizeWithAttributes(nil))
return messages[indexPath.row].sizeWithAttributes(nil)
}
}
Edit: I have got it to work, sorta (in an unoptimized fashion):
func collectionView(collectionView: UICollectionView!, layout collectionViewLayout: UICollectionViewLayout!, sizeForItemAtIndexPath indexPath: NSIndexPath!) -> CGSize {
let cell = TextCollectionViewCell(frame: CGRect(x: 0, y: 8, width: 300, height: 100))
cell.newLabel.text = messages[indexPath.item]
cell.newLabel.sizeToFit()
println(cell.newLabel.intrinsicContentSize())
//var width = UIWindow.
return CGSizeMake(cell.newLabel.intrinsicContentSize().width+10, cell.newLabel.intrinsicContentSize().height+20)
//return cell.newLabel.intrinsicContentSize()
}
Now the text fits in most cases however: It does not fit when it is longer in width than the screen size as obviously a new line is not automatically started. It also is displayed in the middle of the screen, not sure where in the layout I can change this or whether it is dependent on something else.
