Question

I’ve implemented a PickerController to have a user select an image, but I want the image the user selects to be displayed on the UIImageView I have.

I use the following to go to the camera roll:

- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;

picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

[picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];


[self presentModalViewController: picker animated: YES];


[self presentModalViewController: picker animated: YES];

}

Which brings up the camera roll in which a user can click on a photo. However, after the click, it returns to the main view, which is obvious… But how can I assign an action to the button, or image the user selects. Something like UIOKButton?

Something like:

if ([UIImagePickerController presentModalViewController:nil image:nil] == UIOKButton ) {

NSArray *images = [UIImagePickerController images];

for(UIImage* pickerImage in [UIImagePickerController images])

{

myUIImage.image setImage pickerImage;
//^in the view

}

I’m not exactly sure how to go about doing this.

All responses are appreciated.

Thanks!

- (void) makeUIImagePickerControllerForCamera:(BOOL)camera {

     UIImagePickerController *picker = [[UIImagePickerController alloc] init];
     picker.delegate = self;
     picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

     [picker setMediaTypes:[NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil]];

     [self presentModalViewController: picker animated: YES];
}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    // Dismiss the picker
    [[picker parentViewController] dismissModalViewControllerAnimated:YES];

    // Get the image from the result
    UIImage* image = [info valueForKey:@"UIImagePickerControllerOriginalImage"];

    myUIImage.image = image;
}
