Ios UIView底部部件不可单击

在过去的几天里，我遇到了一个让我发疯的奇怪问题。尝试了论坛上建议的各种事情和技巧，但迄今为止运气不佳。基本上，我有一个tabbarview控制器，当用户点击表格行进入详细信息屏幕时，它带有一个tableview。我在屏幕底部有四个固定按钮，但这些按钮不可点击或无法识别触摸。我想这与主屏幕大小或applicationview框架有关。如果我把按钮放在大约CGRectMake（0330320,50）的位置，这意味着在底部留出大约50个空间，那么它们就可以工作了。以下是此问题的相关代码-

//Bottom fixed Bar and Buttons//
self.edgesForExtendedLayout=UIRectEdgeNone;

UIImageView *lineImg=[[UIImageView alloc]init];
//lineImg.frame=CGRectMake(0, 748, 320, 2);
[lineImg setBackgroundColor:[UIColor colorWithRed:0.9058 green:0.4705 blue:0 alpha:1.0]];
[self.view addSubview:lineImg];

  addFavBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[addFavBtn setBackgroundColor:[UIColor colorWithRed:0.0392 green:0.1686 blue:0.2196 alpha:1.0]];

[addFavBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

[helpBtn setTitle:@"Help" forState:UIControlStateNormal];
[helpBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
helpBtn.titleLabel.textAlignment=NSTextAlignmentCenter;
helpBtn.titleLabel.font=[UIFont fontWithName:@"MyriadPro-Regular" size:20];
[helpBtn addTarget:self action:@selector(helpViewBtnClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:helpBtn];

UIImageView *lineImgLast=[[UIImageView alloc]init];
//lineImgLast.frame=CGRectMake(0, 748, 320, 2);

谢谢大家的回复。有趣的是，尽管选项卡栏被隐藏了，但我仍然无法使用保留的按钮空间。在推送details视图控制器之前，我使用了以下行。这似乎是工作良好，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动画：是]

您在链接图像中显示的按钮是否覆盖了选项卡栏控制器的选项卡？如果是这样的话，你是如何让他们不在标签后面的？你有没有试过把你的按钮视图放在主视图的前面？谢谢你的回复，我试过了，但没有成功。detailview中没有选项卡栏视图-

code

[self.view带来的子视图：addFavBtn]；[self.view将子视图带到前台：shareBtn]；[self.view将子视图带到前面：reviewBtn]；[self.view将子视图带到前台：helpBtn]

code

实际上我意识到我正在使用self.tabBarController.tabBar.hidden=YES隐藏tabbarview；但我仍然不能使用底部的选项卡区域。您是否将按钮放置在scrollview中？如果是这样，请尝试直接将按钮添加到scrollview，而不是向视图中添加按钮，因为这可能与视图大小和scrollview内容大小有关。顺便问一下，您使用的是哪一个xcode版本，您是否在ios 7中对此进行了检查？如果您使用的是自动布局，请尝试将其关闭。
