试图禁用按钮使用button.enabled =假，但有没有运气 [英] Trying to disable button using button.enabled = false, but having no luck

问题描述

我，因为我没能有超过我的栏按钮的项目或我的 UIToolbar 任何控制感到沮丧。我试图禁用的UIBarButtonItem ，但它仍然响应触摸事件。以下是我已经做了，code是如此简单，我不知道为什么它不工作。

I'm getting frustrated because I am failing to have any control over my bar button items or my UIToolbar. I am trying to disable a UIBarButtonItem, but it continues to respond to touch events. Here is what I have done, the code is so simple I don't know why it isn't working.

在我的.h：

  IBOutlet UIBarButtonItem *button;

  @property (nonatomic,retain) IBOutlet UIBarButtonItem *button;

和在.M：

  @synthesize button;

  -(void)function{
      button.enabled = false;
  }

我做得不对的代表的ViewController？我不明白为什么我没有得到任何回应。感谢您的帮助。

Am I doing something wrong with the viewcontroller delegate? I don't understand why I get no response. Thanks for your help.

推荐答案

这是正确的：

button.enabled = false;

所以，你确定这种方法实际上是被称为？ （如果这是你的实际code，有一个名为功能？法）

So are you sure that this method is actually being called? (And if this is your actual code, you have a method called 'function'?)
