swift - FBRequestConnection.startWithGraphPath swift 崩溃

Question

我正在使用 Facebook SDK 快速获取用户个人资料数据，但调用 FBRequestConnection.startWithGraphPath:completionHandler: 会 swift 崩溃。

我会留下我认为是日志的相关部分

1.  While type-checking 'profile' at /Users/fratelli/Documents/Projects/Wink/Wink/OAuthFacebookSession.swift:118:14
2.  While type-checking expression at [/Users/fratelli/Documents/Projects/Wink/Wink/OAuthFacebookSession.swift:139:9 - line:142:9] RangeText="FBRequestConnection.startWithGraphPath(
            self.readPermissions(),
            completionHandler: completionHandler
        )"
<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: swift frontend command failed due to signal (use -v to see invocation)
Command /Applications/Xcode6-Beta3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift failed with exit code 254

我已经填写了错误报告。现在，除了使用 Objective-c 之外，我看不到任何其他解决方法。我想知道是否有任何其他 FB SDK 方法我可以尝试达到同样的效果。

代码如下:

    var completionHandler = {
        connection, result, error in
    } as FBSessionStateHandler;

    // Request the profile info
    FBRequestConnection.startWithGraphPath(
        "me?fields=birthday,gender,first_name,last_name,name_format,picture",
        completionHandler: completionHandler
    );

Answer 1

试试这个:

var completionHandler = {
    connection, result, error in
} as FBRequestHandler;

// Request the profile info
FBRequestConnection.startWithGraphPath(
    "me?fields=birthday,gender,first_name,last_name,name_format,picture",
    completionHandler: completionHandler
);

FBRequestConnection.startWithGraphPath 需要 FBRequestHandler，而不是 FBSessionStateHandler
