UICollectionView last cell not aligned

Question

I am new to iOS and now I have a problem.

My goal is to get a sliding panel with filter buttons on it. I have a UICollectionView as a subspecies in some other view, everything displays well except the last cell.

Here is the delegate and date source uicollectionview

class PmtCategoryCollectionViewController: UICollectionViewController {
var categories = ["Mediterranean", "Italian", "French", "Chinese", "American", "Indian"]

var buttonDistanceToEachOther: CGSize = CGSize(width: 20, height: 60)
var fontOnCategoryButton = UIFont.systemFontOfSize(15.0)

override func viewDidLoad() {
    super.viewDidLoad()

    // Uncomment the following line to preserve selection between presentations
    // self.clearsSelectionOnViewWillAppear = false

    // Register cell classes
    self.collectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)

    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

override func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    //#warning Incomplete method implementation -- Return the number of sections
    return 1
}


override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    //#warning Incomplete method implementation -- Return the number of items in the section
    println(categories.count)
    return categories.count
}

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! PmtCategoryCollectionViewCell

    // Configure the cell
    println(categories[indexPath.row])
    cell.category = categories[indexPath.row]
    return cell
}


// determine the size of each cell
func collectionView(collectionView: UICollectionView,
    layout collectionViewLayout: UICollectionViewLayout,
    sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        var text = categories[indexPath.row]
        var size: CGSize = NSString.sizeWithAttributes(text)([NSFontAttributeName:fontOnCategoryButton])
        size.height += buttonDistanceToEachOther.height
        size.width += buttonDistanceToEachOther.width
        return size

}

}

Size of all cells:

Size is (118.91, 72.895)
Size is (37.52, 72.895)
Size is (60.77, 72.895)
Size is (67.025, 72.895)
Size is (75.5, 72.895)
Size is (84.545, 72.895)
Size is (61.745, 72.895)
Size is (176.21, 72.895) 

Any help would be great!

Answer 1

I had the same problem in my case, which helped to simply remove the cell prototype elements from the UICollectionView in the UI Builder and instead use the UICollectionViewCell xib by creating xib and registering it as a cell element somewhere in viewDidLoad:

[collectionView registerNib:[UINib nibWithNibName:@"CustomCell" bundle:nil] forCellWithReuseIdentifier:@"CustomCellIdentifier"];

cellForItemAtIndexPath:

CustomCell* cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CustomCellIdentifier" forIndexPath:indexPath];
