Question

以下是代码，当超过5页的点数仅在点击第4页及以上后响应时，反转时第2和第3点可选择

           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，点在第三个点及以上点击时或之后响应，而反向第二个和第三个点是可选择的 [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];

     }

我该怎么办？如果我点击第二个点，则当前页面的值不会改变。如果我点击第3个，那么当前页面的值正在改变......

UIPageControl仅在第4页点后响应
