如何将Unknown类（Controller）作为AnyObject分配给其他类的委托？在斯威夫特

Question

我需要帮助将这个Objective-C方法重写为Swift。

目标代码：

- (void)pushViewControllerAnimatedWithMember:(Member *)member withSelf:(id)controller
{
    ZJMHomePageViewController *homePageViewController = [ZJMHomePageViewController new];
    homePageViewController.member = member;
    homePageViewController.delegate = controller;
    [self.navigationController pushViewController:homePageViewController animated:YES];
}

SwiftCode ：

func pushViewControllerAnimatedWithMember(member: Member, withSelf controller: AnyObject?)
{
    let homePageViewController : ZJMHomePageViewController = ZJMHomePageViewController.new()
    homePageViewController.member = member
    homePageViewController.delegate = controller // gives error as Not able to assign any object to delegate
    self.navigationController?.pushViewController(homePageViewController,animated:true)
}

Answer 1

委托属性类型必须是AnyObject，因此您可以将其传递好。基本上，控制器和委托必须是相同的类型，或者在分配它的值时需要添加强制转换（as）
