Swift - AnyObject与Any的区别

1，AnyObject ：代表任何class类型的对象实例。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

class Man{ }   class Woman{ }   let man = Man() let woman = Woman() var arr:[AnyObject] = [man,woman]   for people in arr {     if let m = people as? Man {         println("这是个男人")     }else if let w = people as? Woman {         println("这是个女人")     } }

2，Any ：范围更广，代表除函数外任何类型的实例。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

class Man{ }   class Woman{ }   var arr:[Any] = [Any]() arr.apppend(1) arr.append("hangge.com") arr.append(Man()) arr.append(Woman())   for any in arr {     switch any {         case let any as Int:             println("这是个Int类型")         case let any as String:             println("这是个String类型")         case let any as Man:             println("这是个男人类型")         case let any as Woman:             println("这是个女人类型")         default:             println("这是个未知类型")     } }
