关于UIScrollView批量图片 的问题

在视图中有一个UIScrollView,要显示的图片位于一个数组内,我想要在UIScrollView中显示图片,谢谢。

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;
}

  • 设置UIScrollView的contentSize,然后添加UIImageView到ScrollView。
    [self.myScView addSubView:self.imageView];
    
    
    添加图片到单独的UIImageView。
    
    
    - (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);
        }
    }
