如何在直接来自Web服务解析的UIscrollView中显示图像？

Question

我想在UIScrollView上的UIImageView中显示图像，并使用Touch Event将该图像也从右到左和从左到右更改。图像是NSXml解析的结果，所以我该怎么办请帮助我在这个任务中。我应该怎么做，如果可能的话，再给我看一些例子。谢谢前进.....

Depends on how you obtain the images.

If you get them as URLs, you need to download the actual images. There are examples of doing this.

If you get them as NSData (from downloading them or such), you just have to init a UIImage with the data, eg [UIImage imageWithData:] or [[UIImage alloc] initWithData:] .

Then you just do what everyone else does when adding an image to a scroll view. There are hundreds of examples. In short, add the image to a UIImageView then add that view to the scroll view using addSubview: .
