I am using a shared instance of UIImagePickerController in my application. I am using the Camera Roll as the image source.

Sometimes when the image picker opens, instead of seeing the photos gallery, I am able to see only a blank white screen. This issue is not reproducible every time and happens only some of the times.

有人遇到过这个问题吗？是内存使用问题吗？我在设备上测试时使用Instruments检查了应用程序，但似乎内存不是问题。

Thanks for any help.
