Screen goes black after segue

问题 I have tried to debug this but to no avail. Basically when I segue from the first view controller to the second view controller the screen goes black momentarily.

iOS流布局UICollectionView系列三——使用FlowLayout进行更灵活布局 一、引言 前面的博客介绍了UICollectionView的相关方法和其协议中的方法，但对布局的管理类UICollectionViewFlowLayout没有着重探讨，这篇博客介绍关于布局的相关设置和属性方法。 UICollectionView的简单使用： http://my.oschina.net/u/2340880/blog/522613 UICollectionView相关协议方法： http://my.oschina.net/u/2340880/blog/522613 通过layout的设置，我们可以编写更加灵活的布局效果。 二、将九宫格式的布局进行升级 在第一篇博客中，通过UICollectionView，我们很轻松的完成了一个九宫格的布局，但是如此中规中矩的布局方式，有时候并不能满足我们的需求，有时我们需要每一个Item展示不同的大小，代码如下： - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib.
