当我获取用户的Facebook个人资料信息时，我的应用程序中的Fabric上注册了崩溃。它仅在发布版本时崩溃。即使多次尝试，我也无法重现崩溃。我正在单独的网络管理器类中获取配置文件。我已经使用闭包和回调实现了它。
下面是Fabric的堆栈跟踪和崩溃报告。

下面是LoginViewController中的函数，我在其中从NetworkManager中调用fetchFBProfile函数：
func fetchUserProfile()
{
NetworkManager.sharedInstance.fetchFBProfile() { [unowned self] (responseStatus: ResponseStatus, responseObj: FBProfileResponse) in
if responseStatus.status == "Success"
{
self.fbSignIn(responseObj)
}
else{
if responseStatus.display == 1
{
self.showBanner(Strings.failureHeaderMsg, responseStatus.message, true, true)
}
else{
self.showBanner(Strings.failureHeaderMsg, Strings.serverErrorMsg, true, true)
}
}
}
}
下面是NetworkManager中的fetchFBProfile函数：
func fetchFBProfile( _ completion: @escaping GenericResponseWithObj<FBProfileResponse>) -> Void {
let connection = GraphRequestConnection()
progress.show(style: ProgressStyle())
connection.add(MyProfileRequest()) { response, result in
switch result {
case .success(let response):
let fBProfileResponse = FBProfileResponse()
fBProfileResponse.birthday = response.birthday
fBProfileResponse.email = response.email
fBProfileResponse.gender = response.gender
fBProfileResponse.id = response.id
fBProfileResponse.locale = response.locale
fBProfileResponse.name = response.name
fBProfileResponse.profilePictureUrl = response.profilePictureUrl
completion((0, "Success", "Facebook SignIn Successful"), fBProfileResponse)
case .failed(let error):
print("Custom Graph Request Failed: \(error)")
self.progress.dismiss()
completion((0, "Failure", "Couldn't fetch user response"), FBProfileResponse())
}
}
connection.start()
}
我无法从Fabric上了解崩溃报告，而且该应用程序在我的视线中也可以正常使用。任何帮助将不胜感激。谢谢
