2.增添并设置手势的代理为当下VC

if ([self.navigationController.  respondsToSelector:@selector(interactivePopGestureRecognizer)]) {

//使用自定义的手势替换系统的侧边触发手势

//设置手势的代理

[self syPanGesture].delegate = (self.sy_interactivePopDisabled == YES) ? nil : self;

//将自定义手势增添到vc的view上

[self.view addGestureRecognizer:[self syPanGesture]];

  }

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizerNS_AVAILABLE_IOS(7_0);

// 没有触摸事件发生,所有手势识别的默认状态UIGestureRecognizerStatePossible,// 一个手势已经开始但尚未改变或者完成时UIGestureRecognizerStateBegan,// 手势状态改变UIGestureRecognizerStateChanged,// 手势完成UIGestureRecognizerStateEnded,// 手势取消,恢复至Possible状态UIGestureRecognizerStateCancelled, // 手势失败,恢复至Possible状态UIGestureRecognizerStateFailed,// 识别到手势识别UIGestureRecognizerStateRecognized = UIGestureRecognizerStateEnded

代码Demo

GitHub :SYPopGesture

:self.navigationController.interactivePopGestureRecognizer.delegate = self

  • UITapGestureRecognizer

  • UIPinchGestureRecognizer

  • UIPanGestureRecognizer

  • UISwipeGestureRecognizer

  • UIRotationGestureRecognizer

  • UILongPressGestureRecognizer

1.利用自定义UIPanGestureRecognizer替换系统的手势

//设置系统手势不可用

self.navigationController.interactivePopGestureRecognizer.enabled = NO;

//获取手势的代办对象

id target = self.navigationController.interactivePopGestureRecognizer.delegate;

//获取手势响应的点子

SEL backGestureSelector = NSSelectorFromString(@"handleNavigationTransition:");

panGesture = [[UIPanGestureRecognizer alloc]initWithTarget:target action:backGestureSelector];

// called once per attempt to recognize, so failure requirements can be determined lazily and may be set up between recognizers across view hierarchies

4.UISlider的响应

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{

//当拖动的是slider时,该事件不让panGesture手势响应

if ([touch.view isKindOfClass:[UISlider class]]) {

return NO;

}

return YES;

}

self.navigationController.interactivePopGestureRecognizer.enabled = NO;

  • 当想给八个view同期增添多少个手势的时候,在手势的那一个代理方法重临yes,表示同意同一时候识别七个手势- gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;

缓和思路

>使用自定义手势替换系统的侧滑手势

>target 及 action 不变

>将自定义手势增多到UIVIewController的view上,达成手势在分化vc中的分歧响应

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldReceiveTouch:(UITouch*)touch;

  1. 开创手势:UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] init];

  2. 设置手势相应的习性:

    // 连续敲击2次tap.numberOfTapsRequired = 2;// 需要2根手指一起敲击tap.numberOfTouchesRequired = 2;
    
  3. 将手势增加到view上:[self.iconView addGestureRecognizer:tap];

  4. 监听手势的触及:[tap addTarget:self action:@selector(tapIconView:)]

参照他事他说加以考察资料

1.全屏回去手势 FDFullscreenPopGesture

2.一行代码,让您的接纳中UIScrollView的滑行与侧滑再次来到并存 TZPopGesture

三 ,怎么样设置总体页面滑动再次回到?

  • 要想依靠手势的剧情,做出相应的动作,就把手势传过来
  • 要想凭借手势的偏移量设置view的地方的时候,临时需求对手势的有的变量实行复位,它们也许是依赖发轫点来计量的。(掌握就行,到用时,具体意况具体比较)

5.拖动中别的情状的拍卖

- (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)gestureRecognizer {

if ([[self.navigationController valueForKey:@"_isTransitioning"] boolValue]) {

return NO;

}

if ([self.navigationController.transitionCoordinator isAnimated]) {

return NO;

}

if (self.navigationController.viewControllers.count < 2) {

return NO;

}

return YES;

}

gesture.delegate = self;

6.落到实处全屏和侧边响应

- (BOOL)gestureRecognizerShouldBegin:(UIPanGestureRecognizer *)gestureRecognizer {

if ([[self.navigationController valueForKey:@"_isTransitioning"] boolValue]) {

return NO;

}

if ([self.navigationController.transitionCoordinator isAnimated]) {

return NO;

}

if (self.navigationController.viewControllers.count < 2) {

return NO;

}

// 侧滑手势触发地点

CGPoint location = [gestureRecognizer locationInView:self.view];

CGPoint offSet = [gestureRecognizer translationInView:gestureRecognizer.view];

//触发上涨的幅度,

CGFloat maxLocationX = self.sy_isFullPopGesture == YES ? CGRectGetWidth(self.view.bounds) : 40.f;

//当是全屏重临击势时,使用成套宽度

BOOL ret = (0 < offSet.x && location.x <= maxLocationX);

return ret;

}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer*)gestureRecognizer;

解决进度

3 设置代理 增多手势

3.UIScrollView 手势的响应

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {

//当panGesture相应战败时,才响应scrollView的拖入手势

[otherGestureRecognizer requireGestureRecognizerToFail:gestureRecognizer];

return YES;

}

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldReceivePress:(UIPress*)press;

1 获取边缘滑动重临对象

2 调用全屏滑入手势

[self.view addGestureRecognizer: gesture];

// return YES to set up a dynamic failure requirement between gestureRecognizer and otherGestureRecognizer

// called before touchesBegan:withEvent: is called on the gesture recognizer for a new touch. return NO to prevent the gesture recognizer from seeing this touch

// note: returning YES is guaranteed to allow simultaneous recognition. returning NO is not guaranteed to prevent simultaneous recognition, as the other gesture's delegate may return YES

// note: returning YES is guaranteed to set up the failure requirement. returning NO does not guarantee that there will not be a failure requirement as the other gesture's counterpart delegate or subclass methods may return YES

//

// called before pressesBegan:withEvent: is called on the gesture recognizer for a new press. return NO to prevent the gesture recognizer from seeing this press

二 ,屏蔽系统自带滑动再次来到

并设置代理:UIGestureRecognizerDelegate

// return YES to allow both to recognize simultaneously. the default implementation returns NO (by default no two gestures can be recognized simultaneously)

四。UIGestureRecognizerDelegate

一 ,在iOS7.0自此加多了边缘滑动再次回到,要是在被push的调控器设置了自定义导航条只怕自定义左button的时候会失灵,通过那句话可以化解

// called when the recognition of one of gestureRecognizer or otherGestureRecognizer would be blocked by the other

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizerNS_AVAILABLE_IOS(7_0);

[self.view addGestureRecognizer: gesture];

- (BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizer;

//

id obj = self.navigationController.interactivePopGestureRecognizer.delegate;

gesture.delegate = self;

UIPanGestureRecognizer *gesture= [[UIPanGestureRecognizer alloc] initWithTarget:obj action:@selector(handleNavigationTransition:)];

// called when a gesture recognizer attempts to transition out of UIGestureRecognizerStatePossible. returning NO causes it to transition to UIGestureRecognizerStateFailed
