如何以编程方式触发 uibarbuttonitem 单击事件 [英] How to fire uibarbuttonitem click event programmatically

问题描述

我创建了一个 UIActionSheet

UIActionSheet * action = [[UIActionSheet alloc]initWithTitle:@""
                                                              delegate:self
                                                     cancelButtonTitle: @"cancel"
                                                destructiveButtonTitle: @"OK"
                                                     otherButtonTitles: nil];
          [action showInView:self.view];
          [action release];

在 UIActionSheet 中的取消按钮事件中，我想触发在我看来的 UIBarButtonItem 事件.

On the event of the cancel button in the UIActionSheet I want to fire the event of a UIBarButtonItem, which is in my view.

我的问题是如何在 UIActionSheet 委托方法中触发按钮事件(不触摸按钮)

My question is how can I fire the button event(without touching the button) in the UIActionSheet delegate method

推荐答案

不知道当前栏按钮项目动作的你可以这样调用:

Not knowing the current bar button item action you can invoke it this way:

[barButtonItem.target performSelector:barButtonItem.action]

然而，这会带来未知选择器"编译器警告，但这可能已解决.

This will however bring "unknown selector" compiler warning, but this may be worked around.
