ios - UILabel_長按複製

標籤：stat   visible   shared   div   can   ges   name   ati   first   

 

1.添加長按的手勢

UILongPressGestureRecognizer *longGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(showMenuAction:)]; 
[self.lable setUserInteractionEnabled:YES]; [self.lable addGestureRecognizer:longGesture];

 

 

 

2.實現方法

- (BOOL)canBecomeFirstResponder{    return YES;}- (BOOL)canPerformAction:(SEL)selector withSender:(id) sender {    if (selector == @selector(copy:)) {        return YES;    }    return NO;}- (void)copy:(id)sender {    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];    [pasteboard setString:self.lable.text];}- (void)showMenuAction:(UILongPressGestureRecognizer *)sender {    if (sender.state == UIGestureRecognizerStateBegan) {        [self becomeFirstResponder];        CGPoint location = [sender locationInView:[sender view]];        UIMenuController *menuController = [UIMenuController sharedMenuController];        [menuController setTargetRect:CGRectMake(location.x, location.y, 0.0f, 0.0f) inView:sender.view];        [menuController setMenuVisible:YES animated:YES];    }}
