滑动手势也算是iOS中交互中很重要的一部分，上下左右滑动，UISwipeGestureRecognizer可以很轻松的解决这个问题，没什么难度直接看代码吧:

UISwipeGestureRecognizer *upSwipeGestureRecognizer=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeGestureRecognizer:)];
upSwipeGestureRecognizer.direction=UISwipeGestureRecognizerDirectionUp;[self.view addGestureRecognizer:upSwipeGestureRecognizer];
UISwipeGestureRecognizer *downSwipeGestureRecognizer=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeGestureRecognizer:)];
downSwipeGestureRecognizer.direction=UISwipeGestureRecognizerDirectionDown;[self.view addGestureRecognizer:downSwipeGestureRecognizer];
UISwipeGestureRecognizer *leftSwipeGestureRecognizer=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeGestureRecognizer:)];
leftSwipeGestureRecognizer.direction=UISwipeGestureRecognizerDirectionLeft;[self.view addGestureRecognizer:leftSwipeGestureRecognizer];
UISwipeGestureRecognizer *rightSwipeGestureRecognizer=[[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeGestureRecognizer:)];
rightSwipeGestureRecognizer.direction=UISwipeGestureRecognizerDirectionRight;[self.view addGestureRecognizer:rightSwipeGestureRecognizer];

-(void)swipeGestureRecognizer:(UISwipeGestureRecognizer *)recongnizer{
if (recongnizer.direction==UISwipeGestureRecognizerDirectionUp) {
NSLog(@"向上滑动");
NSLog(@"博客园-FlyElephant");
}
if (recongnizer.direction==UISwipeGestureRecognizerDirectionDown) {
NSLog(@"向下滑动");
NSLog(@"原文地址:http://www.cnblogs.com/xiaofeixiang");
}
if (recongnizer.direction==UISwipeGestureRecognizerDirectionLeft) {
NSLog(@"向左滑动");
NSLog(@"iOS技术交流群:228407086");
}
if (recongnizer.direction==UISwipeGestureRecognizerDirectionRight) {
NSLog(@"向右滑动");
}
