我正在使用storyboard和默认取消按钮。

I am using storyboard and default cancel button .

请帮忙。谢谢。

推荐答案

UITableView's implementation of -layoutSubviews needs to call super.

我认为这是问题所在。

检查所有UITableView的layoutSubviews实现，添加 [super layoutSubviews]; 。

Check all of your UITableView's layoutSubviews implementation, add [super layoutSubviews];.

- (void)layoutSubviews{
    [super layoutSubviews];
    //to do other things
}
