方便快捷的添加button的长按事件，并且复制到剪切板

先设置一个按钮button【这里不再累述】

//button长按事件

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

    longPress.minimumPressDuration = 0.8; //定义按的时间

    [_button addGestureRecognizer:longPress];

-(void)btnLong:(UILongPressGestureRecognizer *)gestureRecognizer{

    if ([gestureRecognizer state] == UIGestureRecognizerStateBegan) {

        NSLog(@"长按事件");

        NSString *message = NSLocalizedString(@"是否复制到剪切板？", nil);

        NSString *otherButtonTitle = NSLocalizedString(@"确定", nil);

        NSString *cancleButtonTitle = NSLocalizedString(@"取消", nil);

        

        UIAlertController *homealertController = [UIAlertController alertControllerWithTitle:nil message:message preferredStyle:UIAlertControllerStyleAlert];

        

        UIAlertAction *otherAction = [UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

//复制文字到剪切板

　　　　UIPasteboard *pboard = [UIPasteboard generalPasteboard];

            pboard.string = _button.titleLabel.text;

            

//复制图片到剪切板           

            UIPasteboard *pboard = [UIPasteboard generalPasteboard];

            pboard.image =_button.imageView.image;

        }];

        UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:cancleButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

            

        }];

        

        [homealertController addAction:cancleAction];

        [homealertController addAction:otherAction];

        [self presentViewController:homealertController animated:YES completion:nil];

    }

}

 以上就可以实现简单快捷的添加按钮的长按事件，并且能够复制到剪切板上，快准狠。。。。。。
