UIView底部不可点击

Question

我有这个奇怪的问题，这是最近几天驱动我的坚果。尝试了论坛中提出的各种各样的东西和窍门，但迄今为止没有运气。基本上我有tabbarview控制器与桌面视图时，用户单击它所需的表格行到详细画面。我在屏幕底部有四个固定按钮，但这些按钮不可点击或不能识别触摸。我想这是与主屏幕尺寸或应用程序视图框架。如果我将按钮放在大约CGRectMake（0,330,320,50）处，这意味着在底部留下大约50个净空间然后它们就可以工作。下面是针对此问题相关的代码 -

//Bottom fixed Bar and Buttons//

谢谢大家的响应。有趣的是，即使tabbar仍然隐藏，我无法使用该按钮的保留空间。在推送细节视图控制器之前，我已经使用了以下行。这似乎工作正常，我现在可以点击所有按钮。

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

objDetailView.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController：objDetailView animated：YES];
