你可以把xib文件发给我吗，我测试下看什么原因引起的这个问题？

[jacylouis]

你好,我已经找到原因了,原因是DVVCover.m 文件里, 的 - (NSString *)coverAtPath:(NSString *)path xibType:(DVVCoverXibType)xibType {....}方法里面 的 switch {}方法里

switch (xibType) {
    case DVVCoverXibTypeUIView:
    case DVVCoverXibTypeUIViewController:
        view = root[@"objects"][@"view"];
        break;

.
.

我改成了这样

switch (xibType) {
    case DVVCoverXibTypeUIView:
       view = root[@"objects"][@"view"];
      break;
    case DVVCoverXibTypeUIViewController:
        view = [@"objects"][@"viewController"][@"view"];
        break;

.
.
因为我用的是一个里面包含一个viewController 的Xib 来进行解析的. 我发现你的这个项目是一个很好的雏形,最近在重构以前含有大量StoryBoard 的项目,正好需要这样的一个工具,然后我在你的代码的基础上又进行了改造,以符合自己的项目要求.真的非常感谢你的分享.
