在OC中我们直接可以用如下方法即可

[obj  isKindOfClass:[obj class]];

class Person {
    
}

class AsiaMen: Person {
    
}

class ViewController: UIViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let person = AsiaMen()
        
        var arr = [AnyObject]()
        arr.append(person)
        arr.append(self)
        
        for obj in arr {
            if obj is Person {
                print("obj对象(\(obj.self)) 是Person类的实例")
            }
        }
    }
}
