iOS5设备上的黑色TabBar [英] Black TabBar on iOS5 device

问题描述

如果我在iOS5下运行我的应用程序似乎都很好。但是如果我尝试使用TabBar加载视图并在其中加入一些视图。

if I run my app under iOS5 all seems to be fine. But if I try to load a view with a TabBar and some views in it.

屏幕看起来就像下图所示，所以黑色标签栏和第一个子视图应该在屏幕上的标签栏已取消分配。我假设，视图和标签栏之间的绑定不存在。

The screen looks actually like the picture below, so a black tabbar and the first subview of the tabbar which should be onscreen is deallocated. I assume, that the binding between the view and the tabbar does not exist.

所以我认为我有办法将视图与标签栏链接起来。

So I think it has something to do how I link the views with the tabbar.

它的工作原理如下：

NSMutableArray* controllersForHome = [[self.tabBarController.viewControllers mutableCopy] autorelease];
[controllersForHome insertObject:somveViewController atIndex:[controllersForHome count]];
[self.tabBarController setViewControllers:controllersForHome];
[someViewController release];

我读过在索引> 0时插入对象应该会有所帮助，但不幸的是没有我的情况。仍然是同样的问题。

I've read that inserting the object at an index >0 should be helpful, but unfortunately not in my case. Still the same issue.

有人猜测并且可以给我一个如何解决这个问题的提示吗？

Has somebody a guess and can give me a hint how to solve that problem?

谢谢，

推荐答案

这就是我在iOS中解决问题的方法5：

this is how I solved the problem in iOS 5:

而不是使用它：

SMutableArray* controllersForHome = [[self.tabBarController.viewControllers mutableCopy] autorelease];

[controllersForHome insertObject:someViewController atIndex:[controllersForHome count]];

[self.tabBarController setViewControllers:controllersForHome];
[someViewController release];

你应该使用这个：

self.tabBarController.viewControllers = [[NSArray arrayWithArray:self.tabBarController.viewControllers] arrayByAddingObject:someViewController];
