Question

我有一个带有几个容器（子）UIiewsController的UIViewContoller。主UIViewController（mvc）包含：

1。）占用整个mvc视图的UICollectionView（它高于mvc.view但低于所有其他控件）。
2。）显示搜索选项（s1vc）
3.）另一个类似于＃2（s2vc）
4。）另一个类似于＃2（s3vc）

我已经为mvc添加了手势识别器，以便用户可以通过从屏幕上滑动来隐藏/显示每个子视图控制器。

问题是，当用户从屏幕上滑动任何svcs时，他们无法滚动mvc的collectionView。

以下是我隐藏/显示svcs的方式：

-(void)swipeLeftGestureHandler:(UIGestureRecognizer*)gestureRecognizer{
    SMLOG(@"Swiped Left");
    if([SMUser activeUser] == nil) return;
    if([self gestureHorizontalScreenSide:gestureRecognizer] == kHorizontalScreenSideLeft){
        [self hideFacets];
    }
    else{
        [self showAccordion];
    }
}
-(void)swipeRightGestureHandler:(UIGestureRecognizer*)gestureRecognizer{
    SMLOG(@"Swiped Right");
    if([SMUser activeUser] == nil) return;
    if([self gestureHorizontalScreenSide:gestureRecognizer] == kHorizontalScreenSideLeft){
        [self showFacets];
    }
    else{
        [self hideAccordion];
    }
}

-(void)hideFacets{
    if(self.facetVisible == NO) return;

    [UIView animateWithDuration:0.25
                     animations:^{
                         CGRect newFrame = self.facetViewController.view.frame;
                         newFrame.origin = CGPointMake(newFrame.origin.x - newFrame.size.width, newFrame.origin.y);
                         self.facetViewController.view.frame = newFrame;
                         self.facetVisible = NO;
                     }
                     completion:^(BOOL finished){
                         self.facetViewController.view.hidden = YES;
                         self.facetViewController.view.userInteractionEnabled = NO;
                     }];
}

-(void)showFacets{
    if([SMUser activeUser] == nil) return;
    if(self.facetVisible == YES) return;

    self.facetViewController.view.userInteractionEnabled = YES;
    [UIView animateWithDuration:0.25
                     animations:^{
                         self.facetViewController.view.hidden = NO;
                         CGRect newFrame = self.facetViewController.view.frame;
                         newFrame.origin = CGPointMake(newFrame.origin.x + newFrame.size.width, newFrame.origin.y);
                         self.facetViewController.view.frame = newFrame;
                         self.facetVisible = YES;
                     }
                     completion:^(BOOL finished){         
                     }];
}

正如你所看到我正在切换svc.view.hidden属性然后我也尝试切换svc.userInteractionEnabled.property但没有运气。仍然无法通过滑动构面视图控制器所在的位置来滑动集合视图。

有什么想法吗？

这里的解决方案是在parentViewController中为容器视图添加另一个插座（使用IB）（我在此代码中将其称为facetContainerView），然后设置它的userInteractionEnabled属性。

-(void)hideFacets{
    if(self.facetVisible == NO) return;
    self.facetVisible = NO;

    [UIView animateWithDuration:0.25
                     animations:^{
                         CGRect newFrame = self.facetViewController.view.frame;
                         newFrame.origin = CGPointMake(newFrame.origin.x - newFrame.size.width, newFrame.origin.y);
                         self.facetViewController.view.frame = newFrame;
                     }
                     completion:^(BOOL finished){
                         self.facetViewController.view.hidden = YES;
                         self.facetContainerView.userInteractionEnabled = NO;
                     }];
}

-(void)showFacets{
    if(self.facetVisible == YES) return;
    self.facetVisible = YES;
    self.facetContainerView.userInteractionEnabled = YES;

    [UIView animateWithDuration:0.25
                     animations:^{
                         self.facetViewController.view.hidden = NO;
                         CGRect newFrame = self.facetViewController.view.frame;
                         newFrame.origin = CGPointMake(newFrame.origin.x + newFrame.size.width, newFrame.origin.y);
                         self.facetViewController.view.frame = newFrame;
                     }
                     completion:^(BOOL finished){         
                     }];
}

我很好奇这个新的视图出口与self.facetViewController.view有何不同，所以我插入这个代码来比较地址（它们确实不同）。我不确定heirarchy，但似乎有一个我不知道的额外视图层。

NSLog(@"self.facetViewController.view: %p", self.facetViewController.view);
NSLog(@"self.facetContainerView: %p", self.facetContainerView);

希望这会在某些时候帮助某人。

如何将触摸事件传递给parentViewController？
