我使用 ctrl + drag

推荐答案

你可以像这样在 Swift 中定义一个通用的 outlet 集合:

you can define a generic outlet collection in Swift like this:

@IBOutlet var collectionOfViews: Array<UIView>? // = [UIView]?

或例如UIButton 对象:

@IBOutlet var collectionOfButtons: Array<UIButton>? // = [UIButton]?

<小时>

您可以在 Outlet Collections 组下找到您的收藏，就像通常在 File's Owner 中一样:

you can find your collections under the Outlet Collections group as usually are in the File's Owner:

它会在连接 5 个随机按钮后显示在我的控制台上:

it would look on my console after connecting 5 random buttons:
