Going to a different view once photo selected from camera/library

I am writing an app that has an initial view containing 2 buttons - one that allows the user to take a photo with the camera and the other that allows him to select a picture from the library.

I've written the code that allows that to happen, but after selecting the picture, I want to go to another view that allows, say, sharing the picture or whatever. Could anyone tell me how to do something like "whenPhotoIsSelected, view = newView"?

This is my code so far:

#pragma mark -
-(IBAction) getCameraPicture: (id) sender{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
开发者_开发问答picker.delegate = self; 
picker.allowsImageEditing = YES; 
picker.sourceType = (sender == takePictureButton) ?
UIImagePickerControllerSourceTypeCamera :
UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[self presentModalViewController:picker animated:YES];

[picker release];

}

I am aware of the existence of

-(void) imagePickerController:(UIImagePickerController *)picker 
didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo

but how exactly do I use it? I tried it and it crashes...

Implement the UIImagePickerControllerDelegate in your ViewController. To do that add <UIImagePickerControllerDelegate> to your ViewController's interface declaration (in the .h file) like so:

@interface YourViewController : UIViewController <UIImagePickerControllerDelegate> {
// instance variable declarations etc.
}

Then in your ViewController's .m file you actually implement the method -(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo instead of calling it, like so:

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {
    // add the new view, for example you could push it on your navigation stack if you use a UINavigationController
}

That method will be called by the UIImagePicker when an image was selected.
