objective-c - 找不到接受提供的参数的 'println' 的重载

Question

我在将我的 Objective-C 代码移植到 Swift 时遇到了一个奇怪的错误。我正在使用 https://github.com/AFNetworking/AFOAuth1Client 的桥接版本如果有帮助。

你能指出我哪里出了问题吗？谢谢。

一个有效的 Objective-C 代码:

[oauthClient authorizeUsingOAuthWithRequestTokenPath:@"oauth_request.php"
    userAuthorizationPath:@"oauth_authorize.php"
    callbackURL:[NSURL URLWithString:@"oob"]
    accessTokenPath:@"oauth_access.php"
    accessMethod:@"POST"
    scope:nil
    success:^(AFOAuth1Token *accessToken, id responseObject) {
        NSLog(@"Success: %@", accessToken);
    } failure:^(NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

Objective-C 中的引用方法原型(prototype):

- (void)authorizeUsingOAuthWithRequestTokenPath:(NSString *)requestTokenPath
                          userAuthorizationPath:(NSString *)userAuthorizationPath
                                    callbackURL:(NSURL *)callbackURL
                                accessTokenPath:(NSString *)accessTokenPath
                                   accessMethod:(NSString *)accessMethod
                                          scope:(NSString *)scope
                                        success:(void (^)(AFOAuth1Token *accessToken, id responseObject))success
                                        failure:(void (^)(NSError *error))failure;

带有 Swift 代码的模板:

oauthClient.authorizeUsingOAuthWithRequestTokenPath(
    requestTokenPath: String?,
    userAuthorizationPath: <#String?#>,
    callbackURL: <#NSURL?#>,
    accessTokenPath: <#String?#>,
    accessMethod: <#String?#>,
    scope: <#String?#>,
    success: ((AFOAuth1Token!, AnyObject!) -> Void)?,
    failure: ((NSError!) -> Void)?
)

一个损坏的 Swift 代码:

oauthClient.authorizeUsingOAuthWithRequestTokenPath(
    requestTokenPath: "oauth_request.php",
    userAuthorizationPath: "oauth_authorize.php",
    callbackURL: "oob",
    accessTokenPath: "oauth_access.php",
    accessMethod: "POST",
    scope: nil,
    success: { (accessToken: AFOAuth1Token!, responseObject: AnyObject!) in
        println("Success")
    },
    failure: { (error: NSError!) in
        println("Failure")
    }
)

正如马特·吉布森建议的那样:

oauthClient.authorizeUsingOAuthWithRequestTokenPath(
    "oauth_request.php",
    userAuthorizationPath: "oauth_authorize.php",
    callbackURL: NSURL(string: "oob"),
    accessTokenPath: "oauth_access.php",
    accessMethod: "POST",
    scope: nil,
    success: { (accessToken: AFOAuth1Token!, responseObject: AnyObject!) in
        println("Success")
    },
    failure: { (error: NSError!) in
        println("Failure")
    }

)

工作起来很有魅力!非常感谢。
