Swift学习--闭包中的懒加载(四)
class ViewController: UIViewController { //格式:定义变量时前使用lazy来修饰变量,后面通过等到赋值一个闭包 // 注意点:1.必须是用var 2.闭包后面必须跟上() lazy var detaList:[String] = { ()->[String] in print("我被骗了") return ["212","213","3231"] }() //如果闭包是用于懒加载,那么in之前的代码都可以删除 包括in在内 lazy var detaList2:[String] = { print("我被骗了2") return ["212","213","3231"] }() let demoFunc = { ()->[String] in print("我被骗了3") return ["212","213","3231"] } lazy var dataList3:[String] = self.demoFunc() override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { print(detaList) print(detaList2) print(dataList3) print(demoFunc()) } }
