Help with code challenge! Not accepting my answer

I don't know what this code challenge is expecting me to write, but I have already tried different approaches to the problem and it doesn't accept any of them. Please help!

This is my current code:

- (IBAction)upload {
    if (self.image != nil && [self.caption length] != 0]) {
      CGSize newSize = CGSizeMake(320.0f, 480.0f);
      CGRect newRectangle = CGRectMake(0, 0, 320.0f, 480.0f);
      UIGraphicsBeginImageContext(newSize);

      // Task 2: Line missing here! How do we draw the image in the resized context?

      UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
      UIGraphicsEndImageContext();

      // Rest of code omitted for brevity!
    }
}

I just changed a curly brace before a comment and it worked -.- Should have worked the other way too.

This is my final code:

- (IBAction)upload {
    if (self.image != nil && [self.caption length] != 0) {
    CGSize newSize = CGSizeMake(320.0f, 480.0f);
    CGRect newRectangle = CGRectMake(0, 0, 320.0f, 480.0f);
    UIGraphicsBeginImageContext(newSize);

    // Task 2: Line missing here! How do we draw the image in the resized context?

    UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    }
    // Rest of code omitted for brevity!
