iOS 应用程序崩溃日志地址簿

Question

我向 AppStore 提交了我的应用程序，Apple 表示它在启动时崩溃。我在所有模拟器和物理设备上对此进行了全面测试，但我无法复制这一点，一切正常。但无论苹果使用什么设备/进程，他们都表示它在发布时就会崩溃。

我得到了崩溃日志并在 XCode 中打开它，并且能够看到哪里似乎崩溃了，但其中的其他所有内容对我来说毫无意义。我无法解释或说出原因。仅通过查看它，当它尝试获取 ABAutorization 并获取 ABContacts 时似乎会崩溃，但我无法复制这个问题，所以我很困惑。希望有人能帮忙:

这是我的 getAB() 函数，以防万一:

static func getABAuth(action: String){
        var addressBook: ABAddressBookRef?
        var error: Unmanaged<CFError>? = nil

        if ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Authorized || ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.NotDetermined{

            Scripts.log("Access Recognized to address book")

            addressBook = ABAddressBookCreateWithOptions(nil, &error).takeRetainedValue()
            if addressBook == nil{
                println(error)
                return
            }
            ABAddressBookRequestAccessWithCompletion(addressBook){
                (granted:Bool, err:CFError!) in
                if granted {
                    //addressBook = addressBook

                    Scripts.log("Access Granted to address book")

                    if (action == "add"){
                        self.addContact(addressBook!)
                    }

                    if (action == "get"){
                        self.getAllContacts(addressBook!)
                    }

                }
                else {
                    println(err)
                }
            }

        }

        if ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Denied{
            Scripts.log("Access denied to address book")
        }

        if ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Restricted{
            Scripts.log("Access restricted to address book")
        }

        //return false

    }

Answer 1

尝试使用可选表达式:

addressBook = ABAddressBookCreateWithOptions(nil, &error)?.takeRetainedValue()
