UITabBarController的子类，替换了TabBar并有一个显示问题 [英] Subclass of UITabBarController, replaced the TabBar and have a display issue

问题描述

我有一个使用标准UITabBarController构建的iPhone应用程序。此应用程序是使用标准的XCode项目模板创建的。

I have an iPhone app which was built using a standard UITabBarController. This app was created using the standard XCode project template.

现在，我需要更改UITabBar看起来很不同。我决定采取的方法是这样：

Now, I have a requirement to change the UITabBar to look very different. The approach I decided to take was like this:

在我的AppDelegate：

in my AppDelegate:

for (UIView *view in tabBarController.view.subviews) {  
    if([view isKindOfClass:[UITabBar class]]) {
        view.hidden = YES;
        break;
    }
}

这会使标签栏隐藏。接下来，我子类化 UITabBarController ，并添加一个 UIToolbar 和一些自定义组件。在我的子类 UITabBarController 我有我的代码设置，以便当我的一个自定义对象被选中，代码只需调用 [self setSelectedIndex：n] 更新UI。

This works to make the tab bar hidden. Next, I subclassed UITabBarController and I add a UIToolbar with a few custom components. In my subclassed UITabBarController I have my code set up so that when one of my custom objects is selected, the code simply calls [self setSelectedIndex:n] to update the UI.

所以我基本上有一个UITabBarController，但我通过一个新的UI控制它。

So I basically have a UITabBarController but I am controlling it through a new UI.

问题是，我的新组件不像普通的 UITabBar 一样高，UITabBarController似乎没有自动调整我的视图大小。我实际上会期望这种行为，但我不知道如何更改UITabBarController的内容框架。任何想法？

The problem is that my new components aren't quite as tall as the normal UITabBar and the UITabBarController seems to be not resizing my views automatically. I actually would expect this behavior, but I can't figure out how to change the "content frame" of a UITabBarController. Any ideas?

推荐答案

解决了以下代码：

[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 436)];

（我知道这个代码有问题btw，会回来困扰我在iPad或其他设备）。

(I know this code has issues btw and will come back to haunt me on the iPad or other devices).
