UIPasteboard粘贴板：UIMenuController自定义（三）

这篇咱总结总结自定义剪贴板的使用

其实自定义剪贴板也非常简单，无非是放开响应时间，通过UIMenuController自定义剪贴板，然后就是最关键的实现你所用的copy方法拉。

为了方便实用，我给cell添加了长按事件，看代码---

UILongPressGestureRecognizer *recognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];

[cell addGestureRecognizer:recognizer];

好，事件加上了，剩下的点击就是实现自定义剪贴板了，上代码：

- (void)longPress:(UILongPressGestureRecognizer *)recognizer{

if (recognizer.state == UIGestureRecognizerStateBegan) {

CopyCell *cell = (CopyCell *)recognizer.view;

[cell becomeFirstResponder];

UIMenuItem *flag = [[UIMenuItem alloc] initWithTitle:@"Flag"action:@selector(flag:)];

UIMenuItem *approve = [[UIMenuItem alloc] initWithTitle:@"Approve"action:@selector(approve:)];

UIMenuItem *deny = [[UIMenuItem alloc] initWithTitle:@"Deny"action:@selector(deny:)];

UIMenuController *menu = [UIMenuController sharedMenuController];

[menu setMenuItems:[NSArray
arrayWithObjects:flag, approve, deny, nil]];

NSLog(@".....%@",NSStringFromCGRect(cell.frame));

[menu setTargetRect:cell.frame
inView:cell.superview];

[menu setMenuVisible:YES
animated:YES];

}

}

通过上面这段代码，自定义剪贴板成功搞定，运行，你猛然会发现，操，怎么剪贴板没有出来，我猜你已经想到为什么了，因为

- (BOOL)canBecomeFirstResponder{

return YES;

}

这么重要的一句话没有加，OK，下面就是你所要使用的方法了

- (void)flag:(id)sender {

NSLog(@"Cell was flagged");

}

- (void)approve:(id)sender {

NSLog(@"Cell was approved");

}

- (void)deny:(id)sender {

NSLog(@"Cell was denied");

}
