如何將集合視圖單元格設置為所有屏幕的相等行單元格

Question

我正在使用swift 2.o集合視圖。 這樣一來，一切正常。 但是，當我在不同的屏幕上運行時，每個單元格之間的寬度差距是不同的。 我在集合視圖的每一行中需要三個單元格，集合視圖中的所有單元格的左，右，上，下分別有8像素的間距。 而且我還需要將單元格設置為拐角半徑。 我需要下面的圖片：[！[在此處輸入圖片描述] [1]] [1]

但是當我在5s屏幕上運行時，我會像這樣，而對於6屏幕就像第二張圖片一樣：

[！[在此處輸入圖片描述] [2]] [2]

iPhone 6 ：

[！[在此處輸入圖片描述] [3]] [3]

看到左，右，底部，頂部之間的間隙不像我的第一幅圖像那樣均勻地縮小。 我需要像我的第一張照片一樣。

我在情節提要中將單元格的最小行空間設置為6。 但我無法像我的初戀一樣。

請幫幫我。

我的popvc.swift：

import UIKit

class popVC: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {

    var tableData: [String] = ["RESTAURANTS", "BANKS", "COFFEE","PIZZA", "HOTELS", "TAXI", "RESTAURANTS", "BANKS","COFFEE","PIZZA", "HOTELS", "TAXI","RESTAURANTS", "BANKS", "COFFEE","PIZZA", "HOTELS", "TAXI"]
    var tableImages: [String] = ["img1.png", "img2.png", "img3.png", "img4.png", "img5.png", "img6.png", "img7.png", "img8.png", "img9.png", "img10.png", "img11.png", "img11.png", "img1.png", "img2.png", "img3.png", "img4.png", "img5.png", "img6.png"]

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return tableData.count
    }

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell: colvwCell = collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath) as! colvwCell
        cell.lblCell.text = tableData[indexPath.row]
        cell.imgCell.image = UIImage(named: tableImages[indexPath.row])
        return cell
    }

    func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        print("Cell \(indexPath.row) selected")
    }


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


}

在故事板中，將大小檢查器的“集合視圖”部分的“插入”設置為“頂部= 8”，“底部= 8”，“左= 8”和“右= 8”，其外觀應類似於

並返回單元格的大小為

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {

   //If you want your cell should be square in size the return the equal height and width, and make sure you deduct the Section Inset from it.
   return CGSizeMake((self.view.frame.size.width/3) - 16, (self.view.frame.size.width/3) - 45);
}

就是這樣，僅此而已。 您應該將結果視為我的：

使用以下代碼創建集合視圖：

@IBOutlet var collectionView: UICollectionView?
    var screenSize: CGRect!
    var screenWidth: CGFloat!
    var screenHeight: CGFloat!

 override func viewDidLoad() {


        print("select block is \(self.strBlockname)")

        screenSize = UIScreen.mainScreen().bounds
        screenWidth = screenSize.width
        screenHeight = screenSize.height
        let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
        layout.sectionInset = UIEdgeInsets(top: 10, left: 0, bottom: 10, right: 0)
        layout.itemSize = CGSize(width: (screenWidth/3)-1, height: (screenWidth/3)-1)
        layout.minimumInteritemSpacing = 1
        layout.minimumLineSpacing = 1
        collectionView = UICollectionView(frame: CGRectMake(0, 0, screenWidth, screenHeight-65), collectionViewLayout: layout)
        collectionView!.dataSource = self
        collectionView!.delegate = self
        collectionView!.registerClass(CollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell")
        collectionView!.backgroundColor = UIColor.whiteColor()
        self.view.addSubview(collectionView!)

        super.viewDidLoad()

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

 func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
        return 1
    }

    func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 20
    }





    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CollectionViewCell", forIndexPath: indexPath) as! CollectionViewCell
        cell.backgroundColor = UIColor.blackColor()
        cell.textLabel?.text = "\(indexPath.section):\(indexPath.row)"
        cell.imageView?.image = UIImage(named: "circle")
        return cell
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

其針對iPhone5s，6s和6+的輸出如下：

@ user5513630在集合視圖中添加以下代碼。

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        let size = UIScreen.mainScreen().bounds.size

// 8 - space between 3 collection cells
// 4 - 4 times gap will appear between cell.
        return CGSize(width: (size.width - 4 * 8)/3, height: 40)

    }
