UIImagePickerController seems to be "broken" in 4.0. Anyone else?

Been working on a 3.1.3 application and recently upgraded to the 4.0 SDK. I'm still building with a Base SDK of 3.1.3 and testing on a 3.1.3 device as well as a device running 4. On 4.0 device, when a UIImagePickerController is displayed I get the following messages:

Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations.
开发者_Go百科
Using two-stage rotation animation is not supported when rotating more than one view controller or view controllers not the window delegate

When the application runs on the 3.1.3 device, it works just fine. No logs, the image shows up when I pick it. When it runs (same code) on the 4.0 device, the logs appear and the delegate method

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

Does not return the image as one of the dictionary keys of info. So it appears to be broken or I am using a deprecated method or something. Anyone else having this issue?

This is a known issue with iOS 4.0. You'll have to wait and hope it's fixed with 4.1.

Doesn't look like you're alone on this issue:
