iOS：在iOS 7.1上我的子类UITabBarController上有更多选项卡崩溃 [英] iOS: More tab crashes on my subclassed UITabBarController on iOS 7.1

问题描述

我只是更新到iOS 7.1，我得到一个名为_layoutCells的函数无法识别的选择错误。

I simply updated to iOS 7.1 and I get an unrecognized selection error for a function called "_layoutCells".

我有一个简单的UITabBarController子类。

I have a simple subclass of UITabBarController.

推荐答案

请注意，在找到更好的解决方案或解释之前，这是一个避免严重崩溃的黑客攻击。我虽然应该分享它。

Note that this is a hack to avoid a bad crash until a better solution or explanation is found. I though I should share it.

只需将以下方法添加到您的UITabBarController子类实现中：

Simply add the following method to your UITabBarController subclass implementation:

- (void) _layoutCells
{
    // HACK ALERT: on iOS 7.1, this method will be called from deep within the bowels of iOS.  The problem is that
    // the method is not implemented and it results in an unrecognized selected crash. So we implement it...
    //
    // What could go wrong?
}
