UISegmentedControl 设置 UITableView、页面控制、scrollview、图像视图

Question

我有一个 4 段的分段控件

segment 1 - 我需要一个页面控件来浏览照片 左右滑动。最多 1-4 张照片

Segment 2 & 3 - 我需要一个表格视图

第 4 段 - 我需要它才能播放视频

我正在这样做

- (IBAction)infoAction:(id)sender {

NSString * selectedTitle = [info titleForSegmentAtIndex:[info selectedSegmentIndex]];


NSLog(@"Selected Title = %@",selectedTitle);//test


switch ([info selectedSegmentIndex])

{   case 0:
    {
        test.text = [frogInfo.imageFiles objectAtIndex:0];
        test.textColor = [UIColor whiteColor];
        [tempImageView setImage:[UIImage imageNamed:@"Detail1Temp.png"]];
        break;

    }


    case 1:

    {    

        test.text = frogInfo.description;
                    test.textColor = [UIColor whiteColor];
        [tempImageView setImage:[UIImage imageNamed:@"Detail2Temp.png"]];
        break;

    }

    case 2:

    {
        test.text = frogInfo.distribution;
        test.textColor = [UIColor whiteColor];
        [tempImageView setImage:[UIImage imageNamed:@"Detail3Temp.png"]];
        break;

    }

    case 3:

    {

        test.text = [frogInfo.videoFiles objectAtIndex:0];
        test.textColor = [UIColor whiteColor];
        [tempImageView setImage:[UIImage imageNamed:@"Detail4Temp.png"]];
        break;

    }

}

}

带有页面控件的图片

部分表格视图

根据我想做的事情，有可能吗？在这个 switch case 函数中？

任何人都可以展示或提供有关如何解决页面控件滑动的教程的链接吗？

尽管我使用 UISlider 而不是分段控件，但我已经做了非常相似的事情 - 你需要的是一个可分页的 UISCrollview，如果每个页面占据 iPhone 的整个宽度，则有 4 个大小相等的页面 (UIViews) 一个接一个地水平加载页面为 320 宽，滚动视图的内容大小宽度为 1280。绑定 UIsegmented 控件以编程方式滚动页面：

假设页面宽度为 320：

     -(IBAction)movepage:(id)sender {
      int xloc = (segmentedController.selectedSegmentIndex * 320);
      CGRect fieldrect = CGRectMake(xloc,0,320, pagesize.height);

    [scrollView scrollRectToVisible:fieldrect animated:YES];

}

加载滚动视图和管理页面控制器：

pagectrl.numberOfPages = 4;
pagectrl.currentPage = 0;

scrollView.pagingEnabled = YES;
scrollView.contentSize=CGSizeMake(320* pagectrl.numberOfPages, 500);
scrollView.showsVerticalScrollIndicator = NO;
scrollView.showsHorizontalScrollIndicator = YES;
scrollView.bouncesZoom = NO;
scrollView.decelerationRate = UIScrollViewDecelerationRateFast;
scrollView.scrollsToTop = NO;


scrollView.delegate = self;
search_url.delegate = self;
user.delegate = self;
password.delegate = self;
rpc_code.delegate = self;


// add pages

int page = 0;

CGRect frame = scrollView.frame;
pagesize = frame.size.width;
frame.origin.y = 0;
frame.origin.x = frame.size.width * page;
firstView.frame = frame;
[scrollView addSubview:firstView];

page ++;
frame.origin.x = frame.size.width * page;
locsubView.frame = frame;
[scrollView addSubview:locsubView];

page ++;
frame.origin.x = frame.size.width * page;
QRgensubView.frame = frame;
[scrollView addSubview:QRgensubView];

page ++;
frame.origin.x = frame.size.width * page;
scansubView.frame = frame;
[scrollView addSubview:scansubView];

page ++;
frame.origin.x = frame.size.width * page;
symbologysubView.frame = frame;
[scrollView addSubview:symbologysubView];


[self registerForKeyboardNotifications];

 CGRect fieldrect = CGRectMake(0,0,320, pagesize);

 [scrollView scrollRectToVisible:fieldrect animated:YES];  //goto 1st page

}

请注意，您可能需要控制或管理用户滚动滚动视图的能力 - 您可以通过设置滚动视图委托来实现 - 下面的代码不符合您的确切要求，但我相信您可以弄清楚休息！

 - (void)scrollViewDidScroll:(UIScrollView *)sender
   {
   // We don't want a "feedback loop" between the UIPageControl and the scroll delegate  in

  // which a scroll event generated from the user hitting the page control triggers updates from

   // the delegate method. We use a boolean to disable the delegate logic when the page control is used.

   //  if (pageControlUsed)
   //  {
  // do nothing - the scroll was initiated from the page control, not the user dragging
  //       return;
  //   }

  // Switch the indicator when more than 50% of the previous/next page is visible

  int page = floor((scrollView.contentOffset.x - pagesize / 2) / pagesize) + 1;
  pagectrl.currentPage = page;



  // A possible optimization would be to unload the views+controllers which are no longer visible
 }
