滾動型不帶的UIView和UIImage的

的UIView包含一個ImageView的
的UIScrollView添加在此的UIView，使滾動（沒有工作）
我有一個AlertView到彈出這個UIView的
我加入的UIImageView，並作爲的UIScrollView UIView的

我每次運行代碼的子視圖，有沒有SI gn的scrollview的存在。我不知道爲什麼。

下面是代碼：

- (void) handleImageTap:(UIGestureRecognizer *)gestureRecognizer { 



    //create image 

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 500, 500)]; 



    //create a scrollview to contain the uiview above 

    UIScrollView* scrollview=[[UIScrollView alloc]initWithFrame:CGRectMake(0,0,320,480)]; 

    scrollview.showsVerticalScrollIndicator=YES; 

    scrollview.scrollEnabled=YES; 

    scrollview.userInteractionEnabled=YES; 

    [scrollview setDelegate:self]; 

    [scrollview setBouncesZoom:YES]; 



    scrollview.contentSize = CGSizeMake(500,500); 

    //create a view to show picture 

    UIView *demoView = [[UIView alloc] init]; 

    if(gestureRecognizer.view == _firstImageView){ 

     UIImage *image = [UIImage imageNamed:_photoDetailModel[1]]; 

     [imageView setImage:image]; 



     CGSize imageSize = imageView.image.size; 

     [demoView setFrame: CGRectMake(0, 0, 290, 200)]; 

//  [demoView setFrame: CGRectMake(0, 0,imageSize.width, imageSize.height)]; 

    }else{ 

     UIImage *image = [UIImage imageNamed:_photoDetailModel[2]]; 

     [imageView setImage:image]; 



     CGSize imageSize = imageView.image.size; 

     [demoView setFrame: CGRectMake(0, 0, 290, 200)]; 

    } 

    //add imageview 

    [demoView addSubview:imageView]; 



    //add scollview 

    [demoView addSubview:scrollview]; 



    //create a pop up view to contain the above uiview 

    CustomIOS7AlertView *alertView = [[CustomIOS7AlertView alloc] init]; 



    // Add some custom content to the alert view 

    [alertView setContainerView: demoView]; 



    // Modify the parameters 

    [alertView setButtonTitles:[NSMutableArray arrayWithObjects:@"Close", nil]]; 



    // You may use a Block, rather than a delegate. 

// [alertView setOnButtonTouchUpInside:^(CustomIOS7AlertView *alertView, int buttonIndex) { 

//  NSLog(@"Block: Button at position %d is clicked on alertView %d.", buttonIndex, (int)[alertView tag]); 

//  [alertView close]; 

// }]; 



    [alertView setUseMotionEffects:true]; 



    // And launch the dialog 

    [alertView show]; 

}

現在要添加的scrollview到demoView。它應該是相反的。

//add scrollview 
[scrollview addSubview:demoView];

如果你想scrollview是警報視圖的內容查看，你也想設置的警報視圖，而不是demoView。

// Add some custom content to the alert view 
[alertView setContainerView:scrollview];

您的最終視圖層次結構應如下：

| AlertView 
| --- ScrollView 
| ------- DemoView 
| ----------- ImageView

工作般的魅力！謝謝！ – 2014-10-01 06:16:14

你能告訴我如何在這種情況下啓用縮放嗎？我嘗試： scrollView.delegate = alertView; 再加入這個滾動視圖的委託方法：但它不工作。 – 2014-10-01 06:59:31

除非您爲警報視圖創建子類，否則您將要將該委託設置爲視圖控制器。然後設置最小和最大縮放比例。最後實現'viewForZoomingInScrollView'方法並返回'demoView'。 – 2014-10-01 14:35:59
