UIView底部不可单击

Question

我遇到了这个奇怪的问题，在过去的几天里，这个问题让我抓狂。尝试了论坛上建议的各种事情和技巧，但到目前为止没有运气。基本上，我有一个带有表视图的选项卡视图控制器，当用户单击它进入详细屏幕的表行时。我在这个屏幕的底部有四个固定按钮，但这些按钮无法点击或无法识别触摸。我想这与主屏幕大小或应用程序视图框架有关。如果我把按钮放在CGRectMake（0330320,50）左右，这意味着在底部留出大约50个空白，那么它们就可以工作了。这是这个问题的相关代码-

感谢大家的回复。有趣的是，即使选项卡是隐藏的，我仍然无法使用为按钮保留的空间。在按下细节视图控制器之前，我已经使用了以下行。这似乎工作得很好，我现在可以点击所有按钮了。

//this one line of code did the trick after spending hours of time
