objective-c - 如何将Unknown class(Controller)分配为AnyObject来委托(delegate)其他某个类？在 swift

我需要帮助将此Objective-C方法重写为Swift。

目标C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];
}

SWIFT代码：

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)
}

最佳答案

委托属性类型必须为AnyObject，以便可以通过它。基本上，控制器和委托必须为相同类型，否则在分配其值时需要添加强制类型转换
