我正在試圖使用UICollectionView與斯威夫特照片庫。我想全屏顯示照片，然後向右滑動即可看到下一張圖像。我有一個肖像框架的工作代碼，但只要我去風景看起來像我的細胞不會重新調整自己的正確位置和大小。UICollectionView horizantal滾動照片庫與swift
這意味着它始終保持肖像畫面的相同width,height,x position和y position。我也得到縱向和橫向框架此錯誤：
- >沒有定義UICollectionViewFlowLayout的行爲，因爲：
- >項目高度必須小於該UICollectionView減去部分插圖的高度頂部和底部值。
我已經在網上搜索了一個答案，並嘗試了所有可能的解決方案，但它似乎並沒有爲我工作。讓我知道是否有人可以幫助這個。非常感激。
這裏是我的代碼：
import UIKit
class ImageDetailViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout,UINavigationControllerDelegate {
@IBOutlet weak var imgDetailCollectionView: UICollectionView!
var index: Int!
var imageItems: Array<Items> = []
var currentIndex: CGFloat!
var size = UIScreen.mainScreen().bounds.size
init(index: Int , imageItems: Array<Items>) {
self.index = index
self.imageItems = imageItems
super.init(nibName: "ImageDetailViewController", bundle: NSBundle.mainBundle())
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func viewDidLoad() {
super.viewDidLoad()
imgDetailCollectionView.registerNib(UINib(nibName: "ImageDetailCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "ImageDetailCollectionViewCell")
//self.automaticallyAdjustsScrollViewInsets = false
imgDetailCollectionView.setZoomScale(0.5, animated: true)
}
override func viewDidLayoutSubviews() {
imgDetailCollectionView.scrollRectToVisible(CGRectMake(320 * CGFloat(index), 0, 320 , 240), animated: false)
}

super.didReceiveMemoryWarning()

cell.setup(imageItems[indexPath.row].url!)
if(UIDeviceOrientationIsPortrait(UIDevice.currentDevice().orientation)){
self.imgDetailCollectionView.collectionViewLayout.invalidateLayout()
var frame = cell.frame
frame.size = CGSizeMake(size.width, size.height)
cell.frame = frame

return cell

}
}
