Im having exactly the same profile image picker controller as your. Here is my code from delegate. I don't think you need everything but you can find some useful information here

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString *mediaType = info[UIImagePickerControllerMediaType];

    if([mediaType isEqualToString:(NSString *) kUTTypeImage]) {

        UIImage *image = info[UIImagePickerControllerOriginalImage];
        UIImage *editedImage = (UIImage *) [info objectForKey:UIImagePickerControllerEditedImage];
        CGRect croppingRect = [info[UIImagePickerControllerCropRect] CGRectValue];

        if (editedImage) {
            image = editedImage;
        } else {
            CGFloat smaller = 1;
            if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
                smaller = 0.9;
            }

            CGFloat width = MIN(image.size.width * smaller, image.size.height * (smaller * 0.95));
            croppingRect = CGRectMake(0 + (image.size.width - width) / 2,
                                      0 + (image.size.height - width) / 2,
                                      width, width);
        }

        UIImage *finalImage = nil;
        if (editedImage) {
            finalImage = [UIImage image:editedImage byScalingAndCroppingForSize:kCroppedImageSize];
        } else {
            finalImage = [UIImage image:image byScalingAndCroppingForSize:kCroppedImageSize];
        }

        if ([self.imagePickerDelegate respondsToSelector:@selector(profileImagePicker:didSelectImage:)]) {
            [self.imagePickerDelegate profileImagePicker:self didSelectImage:finalImage];
        } else {
            NSAssert(nil, @"Delegate should confirm ProfileImagePickerControllerDelegate protocol");
        }

    } else if ([mediaType isEqualToString:(NSString *) kUTTypeVideo]) {
        NSAssert(nil, @"Movie is not supported");
    }
}
