iOS應用崩潰日志通訊錄

Question

我向AppStore提交了應用程序，蘋果公司表示該應用程序在啟動時崩潰。 我在所有模擬器和物理設備上都對此進行了全面測試，但我無法復制它，一切正常。 但是，無論蘋果使用什么設備/過程，他們都說它在啟動時崩潰了。

我得到了崩潰日志，並在XCode中將其打開，並且能夠查看似乎崩潰的地方，但是其中的其他一切對我來說都是沒有意義的。 我無法解釋或說出原因。 僅查看它，似乎在嘗試獲取ABAutorization並獲取ABContacts時便崩潰了，但是我無法復制此問題，因此感到困惑。 希望有人可以幫助您：

這是我的getAB（）函數，以防萬一：

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

    }

嘗試使用可選表達式：

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