Question

how to know image picking in uiimagepicker and how to modify the picking image or how to call after image picking? and how to get the picking image as background image for next view using xcode for iphone?

Answer 1

You can refer UIImagePickercontroller and use the UIImagePickerController’s delegate methods UIImagePickerDelegate

     - (void)imagePickerController:(UIImagePickerController  *)picker didFinishPickingMediaWithInfo:(NSDictionary  *)info
{
// Get the image picked by the image picker
UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
//Do something
}
