IOS--手势控制的使用

手势识别是具有互斥的原则的，比如单击和双击，如果它识别出一种手势，其后的手势将不被识别

// 添加单击的手势UITapGestureRecognize

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] init];

[tapGestureRecognizer addTarget:self action:@selector(tapGestureAction:)]; // 添加点击手势的方法

[self.view addGestureRecognizer:tapGestureRecognizer]; // 添加到当前的View上

// 添加双击的手势UITapGestureRecognize

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] init];

tapGestureRecognizer.numberOfTapsRequired = 2; // 设置单击几次才触发方法

[tapGestureRecognizer addTarget:self action:@selector(tapGestureAction:)]; // 添加点击手势的方法

[self.view addGestureRecognizer:tapGestureRecognizer]; // 添加到当前的View上

添加长按的手势UILongPressGestureRecognizer

注意：会调用两次方法，开始长按调用一次  松开后再调用一次  当长按并且滑动的时候，会多次调用长按的方法

UILongPressGestureRecognizer *pressLongGestureRecognizer = [[UILongPressGestureRecognizeralloc] init];

[pressLongGestureRecognizer addTarget:self action:@selector(pressLongGestureAction:)]; // 给长按手势添加方法

[self.view addGestureRecognizer:pressLongGestureRecognizer]; // 添加到当前的View上

添加捏合的手势UIPinchGestureRecognizer

注意：捏合手势不是捏合一次调用一次方法，而是在捏合的过程中不停的调用方法

UIPinchGestureRecognizer *pinchGestureRecognizer = [[UIPinchGestureRecognizer alloc] init];

[pinchGestureRecognizer addTarget:self action:@selector(pinchGestureAction:)]; // 添加捏合手势的方法

[self.view addGestureRecognizer:pinchGestureRecognizer]; // 添加到当前的View上

添加旋转的手势UIRotationGestureRecognizer

注意：旋转手势是两指同时进行旋转

UIRotationGestureRecognizer *rotationGestureRecognizer = [[UIRotationGestureRecognizeralloc] init];

[rotationGestureRecognizer addTarget:self action:@selector(rotationGestureAction:)]; // 给旋转手势添加方法

[self.view addGestureRecognizer:rotationGestureRecognizer]; // 添加到当前的View上

添加滑动的手势（轻扫手势） UISwipeGestureRecognizer

注意： 快速移动，是用于监测滑动的方向的

UISwipeGestureRecognizer *swipGestureRecognizer = [[UISwipeGestureRecognizer alloc] init];

swipGestureRecognizer.direction = UISwipeGestureRecognizerDirectionUp; // 添加手势的方法

// 以下是设置滑动的方向

// typedef NS_OPTIONS(NSUInteger, UISwipeGestureRecognizerDirection) {

//    UISwipeGestureRecognizerDirectionRight = 1 << 0, // 从左向右滑动

//    UISwipeGestureRecognizerDirectionLeft  = 1 << 1, // 从右向左滑动

//    UISwipeGestureRecognizerDirectionUp    = 1 << 2, // 从下向上滑动

//    UISwipeGestureRecognizerDirectionDown  = 1 << 3  // 从上向下滑动

// };

[swipGestureRecognizer addTarget:self action:@selector(swipGestureAction:)]; // 给滑动手势添加方法

[self.view addGestureRecognizer:swipGestureRecognizer]; // 添加到当前的View上

添加拖移手势（平移手势） UIPanGestureRecognizer

注意：慢速移动，是用于监测偏移的量的

UIPanGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc] init];

[panGestureRecognizer addTarget:self action:@selector(panGestureAction:)]; // 添加托移收拾的方法

[self.view addGestureRecognizer:panGestureRecognizer]; // 添加到当前的View

[panGestureRecognizer release], panGestureRecognizer = nil; // 释放内存

 

#pragma mark - 实现单击手势的方法

- (void)tapGestureAction:(UITapGestureRecognizer *) sender {

NSLog(@"您  轻拍   了屏幕");

}

}

晃动手势

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

{

application.applicationSupportsShakeToEdit = YES;

return YES;

}

-(BOOL)canBecomeFirstResponder {

return YES;

}

-(void)viewDidAppear:(BOOL)animated {

[super viewDidAppear:animated];

[self becomeFirstResponder];

}

- (void)viewWillDisappear:(BOOL)animated {

[self resignFirstResponder];

[super viewWillDisappear:animated];

}

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event

{

if (motion == UIEventSubtypeMotionShake) {

NSLog(@"检测到晃动");

}

}
