我可以将 UIScrollView 放入另一个 UIScrollView 中吗

我有一个UIScrollView仅在垂直方向滚动，我需要放置UIScrollView它可以水平移动，就像苹果设备中的AppStore应用程序一样。我不想我们UICollectionView因为我有静态数据并且我只需 3 个水平UIScrollView

是的你可以。作为UIScrollView子类UIView添加子视图时它将按预期运行。每个滚动视图将根据其启用滚动contentSize财产。

Objective-C：

UIScrollView *horizontalScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(40.0, 40.0, 300.0, 300.0)];
horizontalScrollView.backgroundColor = [UIColor lightGrayColor];
horizontalScrollView.contentSize = CGSizeMake(2000.0, 300.0);
[self.view addSubview:horizontalScrollView];

UIScrollView *verticalScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(40.0, 40.0, 220.0, 220.0)];
verticalScrollView.backgroundColor = [UIColor greenColor];
verticalScrollView.contentSize = CGSizeMake(220.0, 2000.0);
[horizontalScrollView addSubview:verticalScrollView];

Swift:

let horizontalScrollView = UIScrollView(frame: CGRectMake(40.0, 40.0, 300.0, 300.0))
horizontalScrollView.backgroundColor = UIColor.lightGrayColor()
horizontalScrollView.contentSize = CGSizeMake(2000.0, 300.0)
self.view.addSubview(horizontalScrollView)

let verticalScrollView = UIScrollView(frame: CGRectMake(40.0, 40.0, 220.0, 220.0))
verticalScrollView.backgroundColor = UIColor.greenColor()
verticalScrollView.contentSize = CGSizeMake(220.0, 2000.0)
horizontalScrollView.addSubview(verticalScrollView)
