如何获取UIView的访问子视图？

Question

根据此代码,如果我想访问imageView1和imageView2我怎样才能访问它？请给我看一些例子

例子cell.accessoryView.subviews？

UIImageView *imageView1 = [[[UIImageView alloc] init] autorelease];
UIImageView *imageView2 = [[[UIImageView alloc] init] autorelease];
imageView2.alpha = 0;
[cell.accessoryView addSubview:imageView1];
[cell.accessoryView addSubview:imageView2];

Answer 1

您可以使用view的标记属性:

UIImageView *imageView1 = [[[UIImageView alloc] init] autorelease];
imageView1.tag = 100;
UIImageView *imageView2 = [[[UIImageView alloc] init] autorelease];
imageView2.tag = 200;
imageView2.alpha = 0;
[cell.accessoryView addSubview:imageView1];
[cell.accessoryView addSubview:imageView2];

然后使用-viewWithTag:方法获取子视图:

UIImageView *getImageView1 = (UIImageView*)[cell.accessoryView viewWithTag:100];

Answer 2

我相信你可以通过调用访问superview中的所有子视图
[cell.accessoryView subviews].
