shouldReceiveTouch從來沒有所謂

Question

我想一些用戶界面添加到R4PageViewController如按鈕和一個ListView，但不知道這樣做的正確的方式，我shouldReceiveTouch左右決定的發揮，但沒有成功

這裏我的手勢識別器子類

@implementation R4SwipeGestureRecognizer 

- (id)initWithPageViewController:(R4PageViewController *)pageViewController 
{ 
    self = [super initWithTarget:pageViewController action: 
      @selector(handleSwipeFrom:) 
//   nil 
      ]; 
    if (self) { 
    self.pageViewController = pageViewController; 
//  self.delegate = self.pageViewController; 

//  self.cancelsTouchesInView = YES; 
//  self.delaysTouchesBegan = YES; 
//  self.delaysTouchesEnded = YES; 
    } 
    return self; 
} 

//- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer { 
// 
//} 

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
//  super.delegate = self.pageViewController; 
    [super touchesBegan:touches withEvent:event]; 
    UITouch *touch = [touches anyObject]; 
    self.previousTouchPoint = [touch locationInView:self.view]; 
    self.previousTouchTime = CFAbsoluteTimeGetCurrent(); 
    self.state = (self.previousTouchPoint.x > 20) ? UIGestureRecognizerStatePossible : UIGestureRecognizerStateFailed; 
} 

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    [super touchesMoved:touches withEvent:event]; 
    UITouch *touch = [touches anyObject]; 
    CGPoint location = [touch locationInView:self.view]; 

    if (self.state == UIGestureRecognizerStatePossible) { 
    CGFloat dx = location.x - self.previousTouchPoint.x; 
    CGFloat dy = location.y - self.previousTouchPoint.y; 

    if (ABS(dx) > ABS(dy)) { 
     self.state = UIGestureRecognizerStateBegan; 

     // load view controllers 
     if (dx > 0 && !self.pageViewController.previousViewContainer.viewController) { 
     [self.pageViewController loadPreviousViewController]; 
     } else if (dx < 0 && !self.pageViewController.nextViewContainer.viewController){ 
     [self.pageViewController loadNextViewController]; 
     } 

    } else { 
     self.state = UIGestureRecognizerStateFailed; 
    } 
    } else if (self.state == UIGestureRecognizerStateBegan || self.state == UIGestureRecognizerStateChanged) { 
    CFAbsoluteTime time = CFAbsoluteTimeGetCurrent(); 

    CGFloat deltaX = location.x - self.previousTouchPoint.x; 
    CFAbsoluteTime deltaT = time - self.previousTouchTime; 

    UIView *view = self.pageViewController.currentViewContainer; 
    view.origin = CGPointMake(view.origin.x + deltaX, view.origin.y); 

    // load view controllers 
    if (view.origin.x > 0 && !self.pageViewController.previousViewContainer.viewController) { 
     [self.pageViewController loadPreviousViewController]; 
    } else if (view.origin.x < 0 && !self.pageViewController.nextViewContainer.viewController){ 
     [self.pageViewController loadNextViewController]; 
    } 

    view = self.pageViewController.previousViewContainer; 
    view.origin = CGPointMake(view.origin.x + deltaX * self.pageViewController.sidePagesSpaceDelayRate, view.origin.y); 

    view = self.pageViewController.nextViewContainer; 
    view.origin = CGPointMake(view.origin.x + deltaX * self.pageViewController.sidePagesSpaceDelayRate, view.origin.y); 

    self.velocity = deltaX/deltaT; 
    self.previousTouchPoint = location; 
    self.previousTouchTime = CFAbsoluteTimeGetCurrent(); 

    if (self.pageViewController.currentPage == 0 && self.pageViewController.currentViewContainer.origin.x > self.pageViewController.borderPageMaxIndent) { 
     self.pageViewController.currentViewContainer.origin = CGPointMake(self.pageViewController.borderPageMaxIndent, self.pageViewController.currentViewContainer.origin.y); 
    } else if (self.pageViewController.currentPage == self.pageViewController.numberOfPages-1 && self.pageViewController.currentViewContainer.origin.x < -self.pageViewController.borderPageMaxIndent) { 
     self.pageViewController.currentViewContainer.origin = CGPointMake(-self.pageViewController.borderPageMaxIndent, self.pageViewController.currentViewContainer.origin.y); 
    } 

    [self.pageViewController didScrollToOffset:self.pageViewController.currentViewContainer.frame.origin.x]; 

    self.state = UIGestureRecognizerStateChanged; 
    } 
} 

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    [super touchesEnded:touches withEvent:event]; 
    if (self.state == UIGestureRecognizerStateBegan || self.state == UIGestureRecognizerStateChanged) { 
    BOOL pageChanged = NO; 

    UIView *curentVCView = self.pageViewController.currentViewContainer; 
    if (curentVCView.origin.x > curentVCView.size.width/2 && self.pageViewController.currentPage > 0) { 
     [self.pageViewController shiftContainersLeft]; 
     pageChanged = YES; 
    } else if (curentVCView.origin.x < -curentVCView.size.width/2 && self.pageViewController.currentPage < self.pageViewController.numberOfPages-1) { 
     [self.pageViewController shiftContainersRight]; 
     pageChanged = YES; 
    } else if (ABS(self.velocity) > 1000) { 
     if (self.velocity < 0) { 
     if (self.pageViewController.currentPage < self.pageViewController.numberOfPages-1) { 
      [self.pageViewController shiftContainersRight]; 
      pageChanged = YES; 
     } 
     } else if (self.pageViewController.currentPage > 0) { 
     [self.pageViewController shiftContainersLeft]; 
     pageChanged = YES; 
     } 
    } 

    [self.pageViewController animateToRestAndMakeAppearanceUpdates:^{ 
     self.state = UIGestureRecognizerStateEnded; 
     if (pageChanged) { 
     [self.pageViewController didScrollToPage:self.pageViewController.currentPage toController:self.pageViewController.currentViewContainer.viewController]; 
     } 
    }]; 
    } else { 
    self.state = UIGestureRecognizerStateCancelled; 
    } 
} 

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

    CGPoint location = [touch locationInView:self.view]; 
    NSLog(@" y location : %f", location.y); 
    if (location.y< 70 || location.y > 288) 
    { 
     return NO; 
    } 
    if (self.state == UIGestureRecognizerStateBegan || self.state == UIGestureRecognizerStateChanged) { 
    return NO; 
    } else { 
    return YES; 
    } 
} 

@end 

，這裏是初始化函數

@implementation R4PageViewController 

- (id)initWithOptions:(NSDictionary *)options 
{ 
    self.options = [options mutableCopy]; 
    self = [super initWithNibName:@"View" bundle:nil]; 
    if (self) { 
     //  super.view.frame = CGRectMake(0, 70, 320, 288); 
     [self initializePrivateProperties]; 

     //  [self.view addSubview:[self getHeader]]; 

     self.view.backgroundColor = [UIColor whiteColor]; 
     self.view.layer.masksToBounds = YES; 

     [self loadContainerViews]; 

     /* This guy provides swiping mechanism */ 
     R4SwipeGestureRecognizer *r = [[R4SwipeGestureRecognizer alloc] initWithPageViewController:self]; 
     [self.view addGestureRecognizer:r]; 
     self.swipeGestureRecognizer = r; 


     r.delegate = self; 

    } 
    return self; 
} 

，這裏是從頭部的一部分

//! R4PageViewController main class. 
@interface R4PageViewController : UIViewController <UIGestureRecognizerDelegate> 

@property (weak, nonatomic) id<R4PageViewControllerDataSource> dataSource; 
@property (weak, nonatomic) id<R4PageViewControllerDelegate> delegate; 
@property (strong, nonatomic, readonly) UIViewController *currentViewController; 
@property (assign, nonatomic) NSInteger currentPage; 

// Methods 
- (id)initWithOptions:(NSDictionary *)options; 
- (void)reloadData; 

@end 

我的問題：shouldReceiveTouch從未被稱爲

這裏是爲了簡化

Answer 1

我想通這個功能應該被放置在視圖控制器的問題

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

    CGPoint location = [touch locationInView:self.view]; 
    NSLog(@" y location : %f", location.y); 
    if (location.y< 70 || location.y > 288) 
    { 
     return NO; 
    } 
    if (self.state == UIGestureRecognizerStateBegan || self.state == UIGestureRecognizerStateChanged) { 
    return NO; 
    } else { 
    return YES; 
    } 
} 

想法的圖像（R4PageViewController）實現不在委託人（R4SwipeGestureRecognizer）
