关于手势和动态添加的button之间联系的问题

Question

具体情况如下：有一个imageview，imageview下面有一排button，每个button对imageview上的image进行不同的算法处理。button是动态添加的，在和它相连的action中（这个action暂且命名为- (IBAction)processImage : (id) sender ），根据button的不同tag进行相应的switch判断，来确定是执行什么样的算法。  现在的问题是：添加了一个UISwipeGestureRecognizer手势，希望能够实现swipe一下imageview（当然也有可能是self.view,这个不是重点）自动处理下一个button相应的算法。
那么该如何实现呢？

Answer 1

楼主，UISwipeGestureRecognizer会有一个你自定义的监听事件，在这个事件里，把你的当前的button tag +1，然后调用特定tag的算法，你可以算法单独写成方法

UISwipeGestureRecognizer *swipeGestureRecognizer = nil;
    
    swipeGestureRecognizer = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)] autorelease];
    [swipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionUp];
    [self.view addGestureRecognizer:swipeGestureRecognizer];
    
    swipeGestureRecognizer = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)] autorelease];
    [swipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionDown];
    [self.view addGestureRecognizer:swipeGestureRecognizer];
    
    swipeGestureRecognizer = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)] autorelease];
    [swipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionLeft];
    [self.view addGestureRecognizer:swipeGestureRecognizer];
    
    swipeGestureRecognizer = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)] autorelease];
    [swipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionRight];
    [self.view addGestureRecognizer:swipeGestureRecognizer];-(void)swipe:(UISwipeGestureRecognizer *)swipeGestureRecognizer
{
    switch (swipeGestureRecognizer.direction) {
        case UISwipeGestureRecognizerDirectionUp:
            NSLog(@"UISwipeGestureRecognizerDirectionUp");
            //your method
            break;
        case UISwipeGestureRecognizerDirectionDown:
            NSLog(@"UISwipeGestureRecognizerDirectionDown");
            //your method
            break;
        case UISwipeGestureRecognizerDirectionLeft:
            NSLog(@"UISwipeGestureRecognizerDirectionLeft");
            //your method
            break;
        case UISwipeGestureRecognizerDirectionRight:
            NSLog(@"UISwipeGestureRecognizerDirectionRight");
            //your method
            break;
        default:
            break;
    }
}
自己实现swipe方法就可以了。
