有什么帮助吗？！ 推荐答案

我正在猜测您不能使用这样的文件的任意路径。尝试从应用程序的捆绑包开始使用图像文件，然后使用NSBundle URLForResourceWithExtension之类的调用来获取文件。

I'm guessing that you can't use an arbitrary path to a file like that. Try using an image file from your app's bundle to start with, and use a call like NSBundle URLForResourceWithExtension to fetch the file.

如果要从用户的文件中加载文件相机胶卷需要使用适当的API，而不是直接文件路径。 （直接访问文件系统受到应用程序沙箱的严格限制。）

If you want to load a file from the user's camera roll you need to use the appropriate API, not a direct file path. (Direct access to the file system is severely limited by the "app sandbox".)
