在iphone的UIScrollView中滚动图像

我正在使用一个应用程序。在这个随机数的时间里，图像是滚动的。然后停止图像。在我的代码中，第一个随机数是生成的，它存储在n中。例如，随机数是生成12，然后图像是滚动的12倍，然后停止

- (void)viewDidLoad
{
int n = 1 + arc4random() % 10 + 10;

    NSString *string = [NSString stringWithFormat:@"%i",n];

    //lbl.text = string;

    NSUInteger i;
    for (i = 1; i <= kNumImages; i++)
    {


       // [kNumImages addObject:[NSNumber numberWithInt:i]];
        NSString *imageName = [NSString stringWithFormat:@"%d.png", i];
        UIImage *image = [UIImage imageNamed:imageName];
        UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
        CGRect rect = imageView.frame;
        rect.size.height = kScrollObjHeight;
        rect.size.width = kScrollObjWidth;
        imageView.frame = rect;
        imageView.tag = i;  
        lbl.text = string;
        [FirstScrollView addSubview:imageView];
        [imageView release];

        if(n == i){
          break;       

    }

}

-（void）viewDidLoad
{
int n=1+arc4random（）%10+10；
NSString*string=[NSString stringWithFormat:@“%i”，n]；
//lbl.text=字符串；
NSUI；
对于（i=1；i试试这个

- (void)viewDidLoad
{
int n = 1 + arc4random() % 10 + 10;

    NSString *string = [NSString stringWithFormat:@"%i",n];

    //lbl.text = string;

    NSUInteger i;
    for (i = 1; i <= kNumImages; i++)
    {
        if(n == i)
          break;
        else {

       // [kNumImages addObject:[NSNumber numberWithInt:i]];
        NSString *imageName = [NSString stringWithFormat:@"%d.png", i];
        UIImage *image = [UIImage imageNamed:imageName];
        UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
        CGRect rect = imageView.frame;
        rect.size.height = kScrollObjHeight;
        rect.size.width = kScrollObjWidth;
        imageView.frame = rect;
        imageView.tag = i;  
        lbl.text = string;
        [FirstScrollView addSubview:imageView];
        [imageView release];

          }    

    }

}

-（void）viewDidLoad
{
int n=1+arc4random（）%10+10；
NSString*string=[NSString stringWithFormat:@“%i”，n]；
//lbl.text=字符串；
NSUI；
对于（i=1；i[firstScrollView setContentOffset:CGRectMake（n*firstScrollView.frame.size.width，firstScrollView.frame.size.height）]

您只需设置scrollView的内容偏移量
