获取滚动视图中的图像标签

Question

我使用以下代码创建了一个滚动视图：

NSUInteger i;
for (i = 1; i <= kNumImages; i++)
{
    imageName = [NSString stringWithFormat:image, 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;  // tag our images for later use when we place them in serial fashion
    [bigScrollView addSubview:imageView];
}

如何获取视图中当前的图片标签？

Answer 1

你可以通过获取bigScrollView的所有子视图来获取标签。

 for(UIView *subview in [bigScrollView subviews])
 {
     if([subview isKindOfClass:[UIImageView class]])
     {
         NSLog("%d",[subview tag]);
     }
 }
