我将 UILabel 子类化以使用该项目创建可复制的标签。 UILabel 剪贴板

这是它的代码:

- (void) copy: (id) sender
{
    NSLog(@"Copy handler, label: “%@”.", self.text);
}

- (BOOL) canPerformAction: (SEL) action withSender: (id) sender
{
return (action == @selector(copy:));
}

- (void) handleTap: (UIGestureRecognizer*) recognizer
{
    [self becomeFirstResponder];
    UIMenuController *menu = [UIMenuController sharedMenuController];
    [menu setTargetRect:self.frame inView:self.superview];
    [menu setMenuVisible:YES animated:YES];
}

- (BOOL) canBecomeFirstResponder
{
    return YES;
}

并且 NSLog 准确记录了我要在标签内复制的内容,但是,内容不会复制到剪贴板。

任何想法?

以及如何复制图像?
