iOS开发-UISwipeGestureRecognizer滑动手势
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];
