UIPageviewcontroller正在失去姿态

Question

我在UIPageViewController中使用UIScrollView进行捏合和缩放功能。有时UIPageViewController未触摸，页面也不转动。

I think this may help you 

     //*-- pagecontrol 
      pageControl.frame = CGRectMake(0,390,320,30); 
      pageControl.numberOfPages = 2; 
      pageControl.currentPage = 0; 
      [self.view addSubview:pageControl]; 
      pageControl.backgroundColor = [UIColor darkGrayColor]; 



      //*-- Gesture 
      self.pinchGestureRecognizer = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchGesture:)]; 
      self.tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)]; 
      tapGesture.numberOfTapsRequired = 1; 
      [imageview addGestureRecognizer:self.pinchGestureRecognizer]; 
      [imageview addGestureRecognizer:self.tapGesture]; 

    //delegate 
     - (void)scrollViewDidScroll:(UIScrollView *)scrollView { 
      CGFloat pageWidth = self.scrollView.frame.size.width; 
      float fractionalPage = self.scrollView.contentOffset.x/pageWidth; 
      NSInteger page = lround(fractionalPage); 
      self.pageControl.currentPage = page; 


     } 

(void)changePage:(id)sender 
{ 

    //*-- Change the scroll view 

    CGRect frame = scrollView.frame; 
    frame.origin.x = frame.size.width * pageControl.currentPage; 
    frame.origin.y = 0; 
    [scrollView scrollRectToVisible:frame animated:YES]; 
}
