I have an application where I want to allow a user to get a picture from either the camera or the photo library. I'm using the following code.
It works fine in launching the camera or photo library. And clicking on "cancel" sends me back to my app.
But the UIImagePickerController is so slow, it is unusable. I haven't been able to successfully pick a picture yet. It's not crashing, it just hangs forever. I've tested this on both the simulator and the device and have a similar experience.
I'm not sure what is wrong or what to try next. Suggestions?
