【问题描述】：

最近几天我遇到了一个让我发疯的奇怪问题。尝试了论坛中建议的各种事情和技巧，但到目前为止没有运气。基本上，当用户单击进入详细信息屏幕的表格行时，我有一个带有表格视图的 tabbarview 控制器。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应用程序视图框架有关。如果我将按钮放置在 CGRectMake(0,330,320,50) 左右，这意味着在底部留出大约 50 个空白空间，那么它们就可以工作了。这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 setTitle:@"Add Fav" forState:UIControlStateNormal];
[addFavBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
addFavBtn.titleLabel.textAlignment=NSTextAlignmentCenter;
addFavBtn.titleLabel.font=[UIFont fontWithName:@"MyriadPro-Regular" size:20];
[addFavBtn addTarget:self action:@selector(addFavBtnClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:addFavBtn];
addFavBtn.userInteractionEnabled=YES;



UIImageView *lineImg1=[[UIImageView alloc]init];
//lineImg1.frame=CGRectMake(80, 750, 1, 35);
[lineImg1 setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:lineImg1];

shareBtn=[UIButton buttonWithType:UIButtonTypeCustom];
//shareBtn.frame=CGRectMake(81, 750, 79, 35);
[shareBtn setBackgroundColor:[UIColor colorWithRed:0.0392 green:0.1686 blue:0.2196 alpha:1.0]];
[shareBtn setTitle:@"Share" forState:UIControlStateNormal];
[shareBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

[self.view addSubview:shareBtn];

UIImageView *lineImg2=[[UIImageView alloc]init];
//lineImg2.frame=CGRectMake(160, 748, 1, 35);

[self.view addSubview:lineImg2];


reviewBtn=[UIButton buttonWithType:UIButtonTypeCustom];
//reviewBtn.frame=CGRectMake(161, 750, 79, 35);
[reviewBtn setBackgroundColor:[UIColor colorWithRed:0.0392 green:0.1686 blue:0.2196 alpha:1.0]];
[reviewBtn setTitle:@"Review" forState:UIControlStateNormal];
[reviewBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
reviewBtn.titleLabel.textAlignment=NSTextAlignmentCenter;
reviewBtn.titleLabel.font=[UIFont fontWithName:@"MyriadPro-Regular" size:20];
[reviewBtn addTarget:self action:@selector(reviewBtnClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:reviewBtn];

UIImageView *lineImg3=[[UIImageView alloc]init];
// lineImg3.frame=CGRectMake(240, 750, 1, 35);
[lineImg3 setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:lineImg3];

helpBtn=[UIButton buttonWithType:UIButtonTypeCustom];
//helpBtn.frame=CGRectMake(241, 750, 79, 35);
[helpBtn setBackgroundColor:[UIColor colorWithRed:0.0392 green:0.1686 blue:0.2196 alpha:1.0]];
[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);
[lineImgLast setBackgroundColor:[UIColor colorWithRed:0.0392 green:0.1686 blue:0.2196 alpha:1.0]];
[self.view addSubview:lineImgLast];

【问题讨论】：

您在链接图像中显示的那些按钮是否覆盖了标签栏控制器的标签？如果是这样，你是如何让他们不在标签后面的？
您是否尝试过将按钮视图置于主视图的前面？
感谢您的回复，我已经尝试过了，但没有成功。详细视图中没有标签栏视图 - code [self.view bringSubviewToFront:addFavBtn]; [self.view bringSubviewToFront:shareBtn]; [self.view bringSubviewToFront:reviewBtn]; [self.view bringSubviewToFront:helpBtn]; code
实际上我意识到我正在使用 self.tabBarController.tabBar.hidden=YES;但我仍然不能使用这个底部标签栏区域。
您是否将按钮放置在滚动视图中？如果是这样，而不是向视图添加按钮，请尝试直接将按钮添加到滚动视图，因为它可能是视图大小和滚动视图内容大小的问题。顺便说一句，您使用的是哪个 xcode 版本，您是否在 ios 7 中检查过这个？如果您使用自动布局，请尝试将其关闭。

【解决方案1】：

感谢大家的回复。有趣的是，即使标签栏被隐藏了，我仍然无法将保留的空间用于按钮。在推送详细信息视图控制器之前，我使用了以下行。这似乎工作正常，我现在可以单击所有按钮。

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

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