iphone - can't show the scrollview indicator in a scrollview

Question

This is my ViewController:

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.imageView.image = self.image;
    self.scrollView.contentSize = self.imageView.image.size;
    self.imageView.frame = CGRectMake(0, 0, self.imageView.image.size.width, self.imageView.image.size.height);   
    self.title = [self.photo objectForKey:FLICKR_PHOTO_TITLE];
    self.scrollView.delegate = self;
}

- (void)viewDidAppear:(BOOL)animated
{
    [self.scrollView flashScrollIndicators];
    self.scrollView.showsHorizontalScrollIndicator = YES;
}

But it didn't show anything. I already checked out several same questions in here and tried all the possible solutions, but none worked.

水平或垂直滚动​​视图指示器仅在内容大于滚动视图时显示。因此，如果您的完整图像已经显示，则没有指示符。
