iOS點擊手勢UITapGestureRecognizer :

- (void)viewDidLoad {[super viewDidLoad];UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(80, 200, 150, 150)];imgview.image = [UIImage imageNamed:@"6.jpg"];//注意開啟用戶交互imgview.userInteractionEnabled = YES;[self.view addSubview:imgview];UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(imageVIewtap:)]; // tap.delegate = self; //協議//點擊次數 單擊還是雙擊tap.numberOfTapsRequired = 2;//設置屬性 一個手指頭還是多個手指頭點擊tap.numberOfTouchesRequired = 1;//添加[imgview addGestureRecognizer:tap]; }//觸發手勢點擊事件 -(void)imageVIewtap:(UIGestureRecognizer *)tap{self.view.backgroundColor=[UIColor greenColor]; } //默認為單擊UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapClick:)];tap.delegate = self;[view addGestureRecognizer :tap];
iOS清掃手勢 UISwipeGestureRecognizer：

- (void)viewDidLoad {[super viewDidLoad];_imgview = [[UIImageView alloc]initWithFrame:CGRectMake(80, 200, 200, 200)];_imgview.image = [UIImage imageNamed:@"6.jpg"];_imgview.userInteractionEnabled = YES;UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(imageVIewtap:)];pan.delegate=self;//設置屬性pan.minimumNumberOfTouches = 1;[_imgview addGestureRecognizer:pan];[self.view addSubview:_imgview]; }-(void)imageVIewtap:(UIGestureRecognizer *)tap{self.view.backgroundColor=[UIColor greenColor];if (tap.state==UIGestureRecognizerStateBegan) {NSLog(@"開始移動");//縮放圖片self.imgview.transform=CGAffineTransformMakeScale(0.5, 0.5);}else if (tap.state==UIGestureRecognizerStateChanged){NSLog(@"移動中");self.imgview.center=[tap locationInView:self.view];}else if(tap.state==UIGestureRecognizerStateEnded){NSLog(@"移動完成");self.imgview.transform=CGAffineTransformIdentity;} }
iOS長按手勢 UILongPressGestureRecognizer：
