轻扫手势/平移、长按手势

（1）创建故事板

（2）在ViewController.h中设置全局_myView

（3）ViewController.m

#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad{    [super viewDidLoad];    _myView = [[UIView alloc] initWithFrame:CGRectMake(0, 20, 320, 400)];    _myView.backgroundColor = [UIColor greenColor];    [self.view addSubview:_myView];        /*__________________________________手势的使用_____________________________________*/    //_________________________点击手势__________________________    //单击    UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap1Action:)];    //设置点击的次数,默认是1    tap1.numberOfTapsRequired = 1;    //设置点击的手指个数    tap1.numberOfTouchesRequired = 1;    //将点击的手势添加到视图上    [_myView addGestureRecognizer:tap1];        //双击    UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap2Action:)];    //设置点击的次数    tap2.numberOfTapsRequired = 2;    //设置手指个数    tap2.numberOfTouchesRequired = 1;    //添加到视图上    [_myView addGestureRecognizer:tap2];        //如果我们双击则取消单击相应事件（注意：需要取消的手势放在前面）    [tap1 requireGestureRecognizerToFail:tap2];        //_________________________轻扫手势__________________________    UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeAction:)];    //设置轻扫的方向    /*     UISwipeGestureRecognizerDirectionRight  右（默认）     UISwipeGestureRecognizerDirectionLeft      左     UISwipeGestureRecognizerDirectionUp    上     UISwipeGestureRecognizerDirectionDown  下     */    swipe.direction = UISwipeGestureRecognizerDirectionUp;    [_myView addGestureRecognizer:swipe];        //_________________________平移手势__________________________    UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];    [_myView addGestureRecognizer:pan];    //_________________________长按手势__________________________    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)];    //设置长按的最短时间    longPress.minimumPressDuration = 2;    [_myView addGestureRecognizer:longPress];        //_________________________旋转手势__________________________    UIRotationGestureRecognizer *rotation = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationAction:)];    [_myView addGestureRecognizer:rotation];        //_________________________捏合手势__________________________    UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAction:)];    [_myView addGestureRecognizer:pinch];    }#pragma mark - 手势响应事件//单击相应的事件- (void)tap1Action:(UITapGestureRecognizer *)tap {    //取得点击手指的个数//    NSInteger count = tap.numberOfTouches;        CGPoint point = [tap locationInView:_myView];    NSString *str = NSStringFromCGPoint(point);        NSLog(@"单击了,坐标是：%@",str);    }- (void)tap2Action:(UITapGestureRecognizer *)tap {    NSLog(@"双击了");}- (void)swipeAction:(UISwipeGestureRecognizer *)swipe {    if (swipe.direction == UISwipeGestureRecognizerDirectionUp) {        NSLog(@"轻扫了");    }    }//手指移动的时候会不停的调用这个方法：注意此时轻扫不能使用了- (void)panAction:(UIPanGestureRecognizer *)pan {            //可以通过手势取得手势所在的视图    CGPoint point = [pan locationInView:pan.view];//    NSString *str = NSStringFromCGPoint(point);    //    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(point.x, point.y, 5, 5)];//    view.backgroundColor = [UIColor redColor];//    [pan.view addSubview:view];    //    NSLog(@"平移坐标：%@",str);    }- (void)longPressAction:(UILongPressGestureRecognizer *)longPress {    if (longPress.state == UIGestureRecognizerStateBegan) {        NSLog(@"长按开始了");    }else if (longPress.state == UIGestureRecognizerStateEnded) {        NSLog(@"长按结束了");    }}//旋转的时候一直调用- (void)rotationAction:(UIRotationGestureRecognizer *)rt {//    NSLog(@"旋转了");        /*     180/M_PI ＝ 角度／r；          角度 ＝ 180*r/M_PI；     */        CGFloat r = rt.rotation;    //    角度    float jd = 180/M_PI*r;        NSLog(@"jd:%.2f",jd);    }- (void)pinchAction:(UIPinchGestureRecognizer *)pinch {//    NSLog(@"捏合");    //取得缩放的倍数    CGFloat scale = pinch.scale;    //    NSLog(@"scale:%.2f",scale);        pinch.view.transform = CGAffineTransformScale(pinch.view.transform, scale, scale);    }- (void)didReceiveMemoryWarning{    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}@end
