ios数字键盘，点击手势、滑动、长按手势并存，解决手势冲突问题

嗯，之所以有手势冲突，是因为数字键原来的开发定义的是uibutton,有事件冲突。关掉数字键的响应 enabled = false。手势全部加入到数字键的super view，天然的系统就支持流畅的多手势。如果点击的话，就判断点击的点是否落在UILabel的frame里面即可。

 

    //1-0数字数字背景view
            UIView *numberBtnBgView = [[UIView alloc] initWithFrame:CGRectMake(0, 5, self.frame.size.width, 50)];
            numberBtnBgView.userInteractionEnabled = YES;
            //增加滑动手势
            [numberBtnBgView addGestureRecognizer:[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panTopViewChangedMouseLocation:)]];
            //增加单击手势
            UITapGestureRecognizer *tapSuperGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(numberTapGesture:)];
            [numberBtnBgView addGestureRecognizer:tapSuperGesture];
            //增加长按手势
            UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(numberLongPressKeyboardView:)];
            [numberBtnBgView addGestureRecognizer:longPress];
            [self addSubview:numberBtnBgView];
            
            //记录数字键
            self.mutKeyBtns = [NSMutableArray array];
            
            for (int i = 0; i < 10; i ++) {
                YMKeyButton *btn = [[YMKeyButton alloc] initWithFrame:CGRectMake(3+i*(spaceWidth+kYMKeyButtonWidth*(kKeyWindow.width/375.0)), 5, 0, 0)];
                [btn setTitle:@((i+1)%10).stringValue forState:UIControlStateNormal];
                btn.enabled = NO;
                [btn setBackgroundImage:[UIImage imageNamed:@"key_bg_white"] forState:UIControlStateDisabled];
                [self.mutKeyBtns addObject:btn];
                btn.userInteractionEnabled = NO;
                [self addSubview:btn];
            }

对应的手势响应事件：
