1. 在"ViewController.h"中增加两个手势property.

?

@property (nonatomic, strong) UISwipeGestureRecognizer *leftSwipeGestureRecognizer;
@property (nonatomic, strong) UISwipeGestureRecognizer *rightSwipeGestureRecognizer;

并synthesize到"ViewController.m"文件中.

2.在"ViewController.m"文件中的"ViewDidLoad"方法中增加如下代码:

self.leftSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipes:)];
    self.rightSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipes:)];
     
    self.leftSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    self.rightSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
     
    [self.view addGestureRecognizer:self.leftSwipeGestureRecognizer];
    [self.view addGestureRecognizer:self.rightSwipeGestureRecognizer];

- (void)handleSwipes:(UISwipeGestureRecognizer *)sender
{
    if(sender.direction == UISwipeGestureRecognizerDirectionLeft) {
        CGPoint labelPosition = CGPointMake(self.swipeLabel.frame.origin.x - 100.0, self.swipeLabel.frame.origin.y);
        self.swipeLabel.frame = CGRectMake( labelPosition.x , labelPosition.y , self.swipeLabel.frame.size.width, self.swipeLabel.frame.size.height);
        self.swipeLabel.text = @"尼玛的, 你在往左边跑啊....";
    }
     
    if(sender.direction == UISwipeGestureRecognizerDirectionRight) {
        CGPoint labelPosition = CGPointMake(self.swipeLabel.frame.origin.x + 100.0, self.swipeLabel.frame.origin.y);
        self.swipeLabel.frame = CGRectMake( labelPosition.x , labelPosition.y , self.swipeLabel.frame.size.width, self.swipeLabel.frame.size.height);
        self.swipeLabel.text = @"尼玛的, 你在往右边跑啊....";
