swift - Snapchat LoginKit 导致 fatal error (Swift)

Question

我正在尝试使用 Snapchat 的 Bitmoji 和 Login SDK 来允许访问用户的 Bitmoji 头像。但是，当调用 SCSDKLoginClient.login() 时，应用程序立即崩溃。

堆栈跟踪如下:

由于 SnapSDK 需要 Plist 修改，这里还有我的 info.plist:

当然还有我的实际函数调用:

SCSDKLoginClient.login(from: view) { (success, error) in
    guard error == nil else {
        fatalError(error?.localizedDescription ?? "")
    }

    print("success")
}

所有 SDK 均包含在嵌入式二进制文件和链接二进制文件和框架中

非常感谢任何使其正常工作的建议。谢谢。

我遇到了同样的问题并能够解决它。这是我的工作 Info.plist。

注意:您必须将 CFBundleURLSchemes 和 SCSDKRedirectUrl 下的 example 替换为您选择的某个值。我不确定这是否重要，但我们保留了所有字母数字字符。您还必须将 REPLACEME 替换为开发者门户中的客户端 ID。
