ios - 如何在 swift 2.0 中正确对齐 Collection View 单元格

Question

我在使用 UICollectionView 时遇到问题。我制作了一个 Collection View ，它完美地显示了单元格及其元素。但是，问题是应用程序打开时底部单元格被隐藏。之后，如果我滚动到顶部，则最后一行 Collection View 单元格将打开。如何纠正它们？？请引用以下屏幕截图。非常感谢!

它显示如下图(截图一)..

但我想在没有第一次滚动的情况下显示如下图所示的 Collection View 单元格(屏幕截图二)...

我的编码是:

//  ViewController.swift

import UIKit

class ViewController: UIViewController, UICollectionViewDataSource,UICollectionViewDelegate{

    @IBOutlet var collectionView: UICollectionView!

    var titles = ["Events","Visitor Space","Contact Us","Facebook","Videos","WebSite"]
    var icons = [UIImage(named: "cover"),UIImage(named: "cover"),UIImage(named: "cover"),UIImage(named: "cover"),UIImage(named: "cover"),UIImage(named: "cover")]

    override func viewDidLoad() {
        super.viewDidLoad()
    }


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

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = self.collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! HomeCollectionCells
        cell.homeLabel.text = titles[indexPath.row]
        cell.homeImage.image = icons[indexPath.row]
        return cell
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }        
}

尝试在 viewDidLoad 中添加这个

self.automaticallyAdjustsScrollViewInsets = false
