我有一个混合的Swift和Objective C应用程序.swift应用程序使用一些ObjectiveC库来处理OAuth2身份验证.其中一部分是对令牌的OAuth2请求完成后对委托方法的回调.

以下代码正在Objective C库(GTMOAuth2)中执行,该库使用我传入的选择器:

if (delegate_ && finishedSelector_) {
  SEL sel = finishedSelector_;
  NSMethodSignature *sig = [delegate_ methodSignatureForSelector:sel];
  NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:sig];
  [invocation setSelector:sel];
  [invocation setTarget:delegate_];
  [invocation setArgument:&self atIndex:2];
  [invocation setArgument:&auth atIndex:3];
  [invocation setArgument:&error atIndex:4];
  [invocation invoke];
}

我想要调用的函数是在我的swift viewController中,看起来像这样:

func authentication(viewController: GTMOAuth2ViewControllerTouch, finishedWithAuth: GTMOAuth2Authentication, error: NSError)
{
    if (error != nil)
    {
        var alertView: UIAlertView = UIAlertView(title: "Authorisation Failed", message: error.description, delegate: self, cancelButtonTitle: "Dismiss")

        alertView.show()

    }
    else
    {
        // Authentication Succeeded
        self.mytoken = finishedWithAuth.accessToken
    }
}

我目前传入的选择器是: …
