使用Swift对GameKit本地玩家进行身份验证 [英] Authenticate GameKit local player using swift

问题描述

我想快速迁移游戏，我遇到的唯一麻烦是积木/盒盖.这是我不了解的语法，而在目标C中，我将使用:

Im looking to migrate a game over to swift, the only trouble I am having is with blocks/closures. It's the syntax I just don't understand, whereas in Objective C I would use:

GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){
    if (viewController != nil) {
        [self presentViewController:viewController animated:YES completion:nil];
    }
}

等但是我不确定如何在Swift中进行相同的操作.我知道这很简单，但是即使阅读了Swift的书并亲自搜索了一下，我还是无法使它正常工作.我只是一个业余程序员，所以我还远远不够完美.

etc.etc. but I'm not sure how to go about doing the same in Swift. I know it's simple but I just can't get it to work, even after reading the Swift book and googling answers myself. I'm only a hobbyist programmer so I'm far from perfect at all this.

任何帮助将不胜感激.

推荐答案

这是您在Swift中的操作方式:

This is how you would do it in Swift:

var localPlayer = CGLocalPlayer.localPlayer()
localPlayer.authenticateHandler = {(viewController : UIViewController!, error : NSError!) -> Void in
    //handle authentication
}
