uipagecontrol - UIPage 控件仅在第 4 页点后响应

Question

这是代码，当页面超过 5 时，点仅在单击第 4 页及更高页面后才会响应，而反过来，第 2 和第 3 个点是可选的

           if(self.eventDetailPages != Nil)
              [self.eventDetailPages removeFromSuperview]; 
            self.eventDetailPages = [[UIPageControl alloc] init];
            self.eventDetailPages.numberOfPages = self.evtListData.iTotalPages;
            NSLog(@"The total number of pages - %d", self.evtListData.iTotalPages);
            CGSize pageControlSize = [self.eventDetailPages sizeForNumberOfPages:self.eventDetailPages.numberOfPages];
            NSLog(@"The total width of pages - %f", pageControlSize.width);
            self.eventDetailPages.frame = CGRectMake(0, 150, pageControlSize.width,30);
            self.eventDetailPages.backgroundColor   = [UIColor blackColor];
            self.eventDetailPages.center = CGPointMake(self.view.frame.size.width/2, 150);
            self.eventDetailPages.clearsContextBeforeDrawing = TRUE;
            [self.eventDetailPages addTarget:self action:@selector(pageChanged:)  forControlEvents:UIControlEventValueChanged];
            [self.view addSubview:self.eventDetailPages];

在我的情况下，有 4 个点，点仅在单击第 3 个点及以上时或之后响应，而反过来，第 2 个和第 3 个点是可选的 [m_pPageControl addTarget:self action:@selector(gotonextPage:) forControlEvents:UIControlEventTouchUpInside];

   -(void)gotonextPage:(UIPageControl *) pageControl
     {   
      int page = m_pPageControl.currentPage;
       NSLog(@"PAGEVALUE%d",page);
      [m_pScrollView setContentOffset:CGPointMake(page * m_pScrollView.frame.size.width,    0)animated:YES];

     }

我应该怎么办？如果我点击第二个点，当前页面的值不会改变。如果我点击第三个，那么当前页面的值正在改变......
