从UIResponderStandardEditActions执行复制/剪切 [英] Perform copy/cut from UIResponderStandardEditActions

问题描述

这些是UIMenuController宣布的标准动作 http： //developer.apple.com/library/ios/#documentation/uikit/reference/UIResponderStandardEditActions_Protocol/UIResponderStandardEditActions.html

These are standart actions for UIMenuController declared http://developer.apple.com/library/ios/#documentation/uikit/reference/UIResponderStandardEditActions_Protocol/UIResponderStandardEditActions.html

如何手动执行这些方法，像来自另一个UIMenuItem或其他什么？
我找不到合适的选择器:(

How can I perform these methods manually, like from another UIMenuItem or whatever? I can't find the right selector:(

1. [self cut：sender];


2. [UIResponder cut：sender];


3. [[UIMenuController sharedMenuController] cut：sender];


4. 
   
   • （void）cut：（id）sender {[super cut：sender];}
   
   

1. [self cut:sender];
2. [UIResponder cut:sender];
3. [[UIMenuController sharedMenuController] cut:sender];
4. • (void) cut: (id) sender {[super cut:sender];}

到目前为止，这些都不起作用，找不到选择器。

So far non of these don't work, selector not found.

推荐答案

你需要发送响应者链中的操作，从第一响应者开始。试试这个：

You need to send the action along the responder chain, starting with the "first responder". Try this:

[[UIApplication sharedApplication] sendAction:@selector(cut:) to:nil from:self forEvent:nil];

如果你有UIEvent那么触发了该操作，您可以将其作为最后一个参数传递。

If you have the UIEvent that triggered the action, you might pass that as the last parameter.

您可以在 iOS事件处理指南：事件传递：响应者链。

You can read about the responder chain in Event Handling Guide for iOS: Event Delivery: The Responder Chain.
