ios – GPPSignIn与NSInvalidArgumentException崩溃

2023年6月24日 174次阅读

我尝试使用
Google+ Sign-In for iOS指南设置Google登录iOS版.以前我也跟着
Google Platform Getting Started指南.

我的代码如下：

- (void)didTapSignIn {
    GPPSignIn *signIn = [GPPSignIn sharedInstance];
    signIn.shouldFetchGoogleUserEmail = YES;
    signIn.clientID = PTCGoogleClientID;
    signIn.scopes = @[ kGTLAuthScopePlusLogin ];
    signIn.attemptSSO = YES;
    signIn.delegate = self;
    [signIn authenticate];
}

但是,我没有使用Google登录对话框,而是收到以下错误消息：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: object cannot be nil (key: state)'

有人能指出我的代码有什么问题吗？谢谢.

最佳答案 刚刚下载的是Apple于6月17日发布的XCode 6 Beta 2.然后,我重试了代码,它运行正常.
