我正在调用Instagrams API，解析一些图片，然后将它们放入我的collectionview中，这是一堆正方形，就像Instagrams应用一样。当我以编程方式点击其中一个集合视图单元格时，如何切换到新的“详细视图控制器”？
最佳答案
您需要将uiCollecTonViewDelegate（或类似的名称）添加到该ViewController并定义此方法：
//MARK: - UICollectionViewDelegate
func collectionView(collection: UICollectionView, selectedItemIndex: NSIndexPath)
{
//As sender send any data you need from the current Selected CollectionView
self.performSegueWithIdentifier("identifier", sender: self)
}
现在，让它通过或获取SegueController，并将数据设置到所需的新控制器。
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
segue.desntinationViewController as MySegueViewController//(Your Segue View Controller)
// pass data to next view
}
注意：由于我不在我的Mac中，方法的名称可能有语法错误，请使用编辑器或文本完成符来帮助您确定正确的名称。
但有了这个你就可以调用Segue控制器了。还要记住在脚本文件中设置Segue标识符名称，否则它将无法正常工作。
