iphone - UIScrollView 中的多个图像

Question

我的 View 中有一个 UIScrollView。还有一个包含图像的数组，现在我想在 ScrollView 中显示该图像。如果有人帮助我，我是 iPhone 的新手。我会很高兴。

NSMutableArray *images = [[NSMutableArray alloc ] init];

for (int i = 0; i < 10; i++)
{
    NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString     stringWithFormat:@"%d/%d.png",b, i]];
    UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
    [images addObject:img];
    NSLog(@"%@",getImagePath);
    imge.image=img;
}

你需要设置contentSize你的 UIScrollView; 并将您的 UIImageView 添加到您的 ScrollView，例如

[self.myScView addSubView:self.imageView];

并且您需要在单独的 UIImageView 上添加image；

我只想把我的逻辑放在这里:

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

    self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
    self.scrollView.contentSize = CGSizeMake(320, 465);
    self.scrollView.delegate = self;
    [self.view addSubview:self.scrollView];

    int Y = 0;

   // here give you image name is proper so we can access it by for loop.
    for (int i = 1; i <=  totalNumberOFImage; i++)
    {
      UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(0, Y, 100, 100)] ;
      [imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:@"youImageName%d", i]]];
      [self.scrollView addSubview: imageView];
      Y = Y + imageView.frame.size.height+5;

     if(y > 465)
      self.scrollView.contentSize = CGSizeMake(320, y);
    }
}
