今天想找些關(guān)于ios手勢的資料, 結(jié)果看了幾個都跑不起來, 后來東找找, 西找找終于可以弄了個跑起來的例子.......

下面例子主要做個左右滑動手勢.

1. 先創(chuàng)建一個SingleView的項目.

2. 然后在主界面上放一個Label, 主要用于測試滑動是否起作用.

3. 給label增加一個Outlet. 取名為 "swipeLabel"

4. 在"ViewController.h"中增加兩個手勢property.

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

并synthesize到"ViewController.m"文件中.

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

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];  

6.并在"ViewController.m"中增加如下方法;

- (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 = @"尼瑪?shù)? 你在往左邊跑啊...."; 
        } 
        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 = @"尼瑪?shù)? 你在往右邊跑啊...."; 
        } 
    } 

7. 保存, 編譯, 運行....
