向 UITabBar 添加颜色 - 非常非常奇怪的错误？

因此，

我对我的 UITabBarController 进行子类化，并将绿色添加到我的 UITabBar 中。

- (void)viewDidLoad {

    CGRect frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, 48);
    UIView *v = [[UIView alloc] initWithFrame:frame];
    v.backgroundColor = [UIColor greenColor];
    [v setAlpha:0.35];
    [[self tabBar] insertSubview:v atIndex:0];
    [v release];

    [super viewDidLoad];
}

这是不行的。

但是如果我尝试 [[self tabBar] insertSubview:v atIndex:1]; 它可以工作..并且绿色会添加到整个 TabBar !!

我使用 ios5 SDK 开发 iPhone 模拟器，它工作正常，我能够选择所有选项卡。但是当我在 ios4.2（真正的 iPhone）上尝试此代码时，第一个选项卡可见..但不响应触摸

原因很明显，因为添加了 SubView of greenColor @index ==1;

但是如果我更改为 [[self tabBar] insertSubview:v atIndex:0]; 我的第一个选项卡是可选的，但 tabBar 只是不会变成绿色！

敬请指教！！

谢谢。

编辑：

所以问题与iOS5及更早版本有关。 iOS 5 发布后我会编辑答案并放回原来的答案。

现在....前往开发者论坛！ :)

原文

So,

I am subclassing my UITabBarController and I add the color Green to my UITabBar.

- (void)viewDidLoad {

    CGRect frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, 48);
    UIView *v = [[UIView alloc] initWithFrame:frame];
    v.backgroundColor = [UIColor greenColor];
    [v setAlpha:0.35];
    [[self tabBar] insertSubview:v atIndex:0];
    [v release];

    [super viewDidLoad];
}

This does not work .

But if I try [[self tabBar] insertSubview:v atIndex:1]; it Works .. and a green color is added to the entire TabBar !!

I work on the iPhone Simulator using ios5 SDK and it works properly and I am able to select all tabs.
But when I try this code on the ios4.2 (real iPhone), the first tab is visible.. but DOES NOT RESPOND TO TOUCH

The reasons is clear, its because of adding a SubView of greenColor @ index ==1;

But If I change to [[self tabBar] insertSubview:v atIndex:0]; my firstTab is selectable, but the tabBar just does not turn Green !!

Kindly Advise !!

Thanks.

Edit:

So the problem is associated with the iOS5 and the earlier versions. I will edit the answer and put back the original answer once iOS 5 is released.

Right now.... Off to the developer forums !!! :)
