使用滾動視圖和頁面控制器指南屏幕

-2

我想打一個教程屏幕，並已投入滾動視圖和頁面控制器。我想放置圖像，以便用戶可以在第一次啓動時滑過教程屏幕。但我可以把這樣的標籤使用滾動視圖和頁面控制器指南屏幕

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 

    float defWidth = _scrollView.frame.size.width; 
    float defHeight = _scrollView.frame.size.height; 

    _scrollView.pagingEnabled = YES; 
    _scrollView.contentSize = CGSizeMake(defWidth * _pageControl.numberOfPages, _scrollView.frame.size.height); 
    _scrollView.showsHorizontalScrollIndicator = NO; 
    _scrollView.showsVerticalScrollIndicator = NO; 
    _scrollView.scrollsToTop = NO; 
    _scrollView.bounces = NO; 
    _scrollView.delegate = self; 

    UIColor *bgColor[] = {[UIColor orangeColor],[UIColor brownColor],[UIColor grayColor],[UIColor darkGrayColor],[UIColor blackColor]}; 

    for (int i = 0; i < _pageControl.numberOfPages; i++) { 
     UILabel *label = [[UILabel alloc] init]; 
     float x = (defWidth * (float)i); 
     label.frame = CGRectMake(x, 0.0f, defWidth, defHeight); 
     label.backgroundColor = bgColor[i]; 
     label.textColor = [UIColor whiteColor]; 
     label.font = [UIFont fontWithName:@"AppleGothic" size:20]; 
     NSLog(@"%d,%f", i, x); 
     label.text = [NSString stringWithFormat:@"hogehoge%d", (i + 1)]; 
     NSLog(@"%@", label.text); 
     [_scrollView addSubview:label]; 
    } 

}

但我不能把圖像，而不是標籤。我怎樣才能把圖像滾動視圖，使這將是幾張圖片的幻燈片放映？
