Small category I wrote to simplify displaying a UIImagePickerController, asking where the image should come from, and then running all the stuff. Just setup a UIImagePickerControllerDelegate and forget all of the UIActionSheet business.

	// UIImagePickerController+ImageTypeActionSheet.h
	@interface UIImagePickerController (ImageTypeActionSheet)

	- (void)promptImagePickerTypeWithText:(NSString)text titles:(NSArray)titles delegate:(id <UIImagePickerControllerDelegate,UINavigationControllerDelegate>)delegate;

	@end

	// UIImagePickerController+ImageTypeActionSheet.m
	@interface ImageTypeActionSheetDelegate : NSObject
	<UIActionSheetDelegate>
