前言 iOS的组件都是封装好的，又没法看源代码，所以我们不容易知道组件的结构，所以我们可以遍历所有的视图，打印出来，来查看结构 /** 打印层级结构 - parameter superView: view...- parameter level: 0 */ static func printViewHierarchy(superView:UIView,level:Int?...= 0) -> Void { let className = "\(superView.dynamicType)"; let frame = "\(superView.frame)";...{ print("\t", terminator:"") } if let backgroundColor = superView.backgroundColor...backgroundColor)]") }else{ print("\(className) \(frame) [背景色:透明]") } for sonView in superView.subviews
