手势
单击或者双击手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //单击或者双击手势 [self addTapGesture]; }//单击或者双击手势的方法-(void)addTapGesture{ //单击 UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc]init]; //手指数量 tap1.numberOfTouchesRequired = 1; //单击次数 tap1.numberOfTapsRequired = 1; //添加单击方法 [tap1 addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:tap1]; //双击 UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc]init]; //手指数量 tap2.numberOfTouchesRequired = 1; //双击次数 tap2.numberOfTapsRequired = 2; //添加双击方法 [tap2 addTarget:self action:@selector(haha2:)]; [self.view addGestureRecognizer:tap2]; //!!!注意：如果单击和双击同时进行，则取消单击手势(否则，如果单纯双击的话，会先出现一个单击，再出现一个双击) [tap1 requireGestureRecognizerToFail:tap2]; }//单击方法-(void)haha:(UITapGestureRecognizer *)tap{ NSLog(@"单击");}//双击方法-(void)haha2:(UITapGestureRecognizer *)tap{ NSLog(@"双击");}
轻扫手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //轻扫手势 [self addSwipeGesture];}//轻扫手势-(void)addSwipeGesture{ UISwipeGestureRecognizer * swipe = [[UISwipeGestureRecognizer alloc]init]; //设置轻扫方向(如果下面要添加不同方向的方法，则这里不要设置，视具体情况而定) swipe.direction = UISwipeGestureRecognizerDirectionUp; //添加轻扫方法 [swipe addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:swipe]; }//轻扫方法-(void)haha:(UISwipeGestureRecognizer *)swipe{ if (swipe.direction == UISwipeGestureRecognizerDirectionRight) { NSLog(@"向右轻扫"); }else if (swipe.direction == UISwipeGestureRecognizerDirectionLeft){ NSLog(@"向左轻扫"); }else if (swipe.direction == UISwipeGestureRecognizerDirectionUp){ NSLog(@"向上轻扫"); } }
移动手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //移动手势 [self addPanGesture];}//移动手势-(void)addPanGesture{ UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]init]; //添加移动手势的方法 [pan addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:pan];}//移动手势的方法-(void)haha:(UIPanGestureRecognizer *)pan{ NSLog(@"移动");}
长按手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //长按手势 [self addLongPressGesture];}//长按手势-(void)addLongPressGesture{ UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]init]; //长按开始时间(手指按住屏幕5秒，才会开始进入长按时间) longPress.minimumPressDuration = 5; //长按手势方法 [longPress addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:longPress]; }//长按手势的方法-(void)haha:(UILongPressGestureRecognizer *)longPress{ if (longPress.state == UIGestureRecognizerStateBegan) { NSLog(@"长按开始"); }else if (longPress.state == UIGestureRecognizerStateEnded){ NSLog(@"长按结束"); } }
旋转手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //旋转手势 [self addRotationGesture]; }//旋转手势-(void)addRotationGesture{ UIRotationGestureRecognizer *rotation = [[UIRotationGestureRecognizer alloc]init]; //旋转手势方法 [rotation addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:rotation]; }//旋转手势的方法-(void)haha:(UIRotationGestureRecognizer *)rotition{ NSLog(@"旋转"); //获取旋转的弧度制 CGFloat r = rotition.rotation; float degress = 180/M_PI * r; NSLog(@"%f", degress); }
捏合手势
#import "ViewController.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad { [super viewDidLoad]; //捏合手势 [self addPinchGesture]; }//捏合手势-(void)addPinchGesture{ UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]init]; //捏合手势方法 [pinch addTarget:self action:@selector(haha:)]; [self.view addGestureRecognizer:pinch]; }//捏合手势的方法-(void)haha:(UIPinchGestureRecognizer *)pinch{ NSLog(@"捏合手势"); CGFloat scale = [pinch scale]; self.view.transform = CGAffineTransformScale(self.view.transform, scale, scale); }
