谢谢，请帮忙！

变化

[self peformSelector:@selector(popView:) withObject:settingsButton afterDelay:0.95];` 
     ^^

到

[self performSelector:@selector(popView:) withObject:settingsButton afterDelay:0.95];` 
     ^^^

IE添加[R PE和之间 formSelector

感谢这么多，我想我太粗心了！ – user722566 2011-04-30 14:47:05

复制到您的.h文件中：

-(void)popView:(UIView*)view;

应该做的伎俩。

遗憾的是它并没有这样的伎俩 – user722566 2011-04-30 14:27:50
