ios - Pan and Pinch a UIImageView within a ScrollView

Question

I have created a small app using a ScrollView w/ paging and a series of UIImageViews each representing a page. It acts similar to the Photos.app.

I want to be able to pan and zoom individually for each image (page of a scrollview).

What would be the most sound approach to do this? Should I replace the UIImageView page with a scrollview with a UIImage inside it? I would then have a main scroll view where each page of the scrollview had a scrollview with an image inside it that could be pinched,etc.

It seems like a messy approach. I am looking for a clean approach. Any suggestions?

Answer 1

结帐UIPageViewController。该控制器管理每个页面的视图控制器，并使用页面卷曲或滚动等效果在它们之间进行转换。

在您的情况下，您将创建一个视图控制器来管理每个页面的缩放和平移滚动视图。

好吧，据我所知，您建议的方法就是它的完成方式。我用它来创建一个 PDF 查看器，一旦一切就绪，它就不会觉得太乱了。

如果您拥有的这些图像真的很大（很可能是这种情况，因为否则放大它们不会给您带来太多但像素化，但这只是我的一个假设）。
