今天想找些关于ios手势的资料, 结果看了几个都跑不起来, 后来东找找, 西找找终于可以弄了个跑起来的例子.......

下面例子主要做个左右滑动手势.

1. 先创建一个SingleView的项目.

2. 然后在主界面上放一个Label, 主要用于测试滑动是否起作用.

3. 给label增加一个Outlet. 取名为 "swipeLabel"

4. 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.

5.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];

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....";
    }
}

7. 保存, 编译, 运行....
