有创建光泽剪切/复制弹出窗口的界面吗

复制/剪切/粘贴用户界面可以免费使用uikit中的任何基于文本的用户界面控件(uitextfield、uitextview等),但如果您想将类似样式的用户界面用于应用程序的其他部分,则必须创建自己的用户界面。

您要查看uimenuitemcontroller。示例项目“CopyPasteTile”提供了一个自定义实现的示例。

今天早上第二次出现这种情况!

下面是一些示例代码,用于将自定义菜单项添加到uiview子类(它假定您已添加了具有适当目标操作的长按手势识别器):

- (BOOL)canBecomeFirstResponder {
    return YES;
}

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {
    if (action == @selector(laughOutLoud:))
        return YES;
    return NO;
}

- (void)laughOutLoud:(id)sender {
    NSLog(@"LOL!");
}

- (void)gestureRecognizerDidPress:(UILongPressGestureRecognizer*)recognizer {
    if ([recognizer state] == UIGestureRecognizerStateBegan) {
        // Important: the view must become the first responder,
        // and implement the canBecomeFirstResponder method.
        [self becomeFirstResponder];
        UIMenuController *controller = [UIMenuController sharedMenuController];
        UIMenuItem *testItem1 = [[UIMenuItem alloc] initWithTitle:@"Laugh" action:@selector(laughOutLoud:)];
        [controller setMenuItems:[NSArray arrayWithObject:testItem1]];
        [controller update];
        // In real life, the target rect should represent the selection
        [controller setTargetRect:CGRectZero inView:self];
        [controller setMenuVisible:YES animated:YES];
    }
}
