标签栏中的自定义视图在iOS6中不再有效 [英] Custom View in tab bar does no longer work in iOS6

问题描述

我有一个自定义视图（ UILabel + UIImage ），我将其用作<$的自定义视图c $ c> UINavigationController 我这样设置：

I have a custom View (UILabel + UIImage) which I use as the custom view of my UINavigationController which I set like so:

self.navigationItem.titleView = self.myTitleLabel;

这在iOS 5中运行良好但在iOS 6下停止运行。虽然该值设置在调试器，它根本不显示。

This works fine in iOS 5 but ceases to work under iOS 6. Although the value is set in the debugger, it does not show at all.

更新：正如商标指出的那样，文档说明如下：

Update: As mark pointed out the docs states the following:

如果此属性值为 nil ，则当导航栏的标题显示在导航栏的中心时接收器是最重要的项目。如果将此属性设置为自定义标题，则会显示该属性而不是标题。如果 leftBarButtonItem 不是 nil ，则忽略此属性。

If this property value is nil, the navigation item’s title is displayed in the center of the navigation bar when the receiver is the top item. If you set this property to a custom title, it is displayed instead of the title. This property is ignored if leftBarButtonItem is not nil.

现在我有一个 backButton 而不是显式 leftBarButtonItem 。但是如果你想在导航栏中使用你的Logo并且左边还有一个后退按钮或一个栏呢？

Now I have a backButton and not an "explicit" leftBarButtonItem. But what if you want your Logo in the Navigation Bar and still have a Back button or a bar on the left?

推荐答案

我以前用过这种方式，但似乎我喜欢一些解决方法。我建议你使用自己的UIToolBar并隐藏导航栏。这很简单。您唯一需要的是在此处获取返回按钮的图像 http ：//www.teehanlax.com/downloads/ios-5-gui-psd-iphone-4s/ 。

I've used this way before but it seems me like some workaround. I advice you to use your own UIToolBar and hide navigation bar. It's simple. The only what you need is to get image for Back button here http://www.teehanlax.com/downloads/ios-5-gui-psd-iphone-4s/.
