Swift：設置ABRecord的地址屬性

Question

我在這里嘗試設置ABRecord問題（Avinash的答案），並在此處查看 Apple資源（ 在第18頁的底部和第19頁的頂部），以嘗試為ABRecord設置地址。 我盡了最大努力將它們從Objective-C進行翻譯，但是顯然我在某個地方犯了一個錯誤，因為在網上let dict = CFDictionaryCreate(kCFAllocatorDefault, keys, values, 5, &kCFCopyStringDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks)我收到錯誤Cannot assign to immutable value of type 'CFDictionaryValueCallBacks' 。

這是我的代碼：

    let information: ABRecord = ABPersonCreate().takeRetainedValue()

    let address: ABMutableMultiValueRef = ABMultiValueCreateMutable(ABPropertyType(kABMultiDictionaryPropertyType)).takeUnretainedValue()

    var keys = [CFStringRef]()
    var values = [CFStringRef]()

    keys.append(kABPersonAddressStreetKey)
    keys.append(kABPersonAddressCityKey)
    keys.append(kABPersonAddressStateKey)
    keys.append(kABPersonAddressZIPKey)
    keys.append(kABPersonAddressCountryKey)
    keys.append(kABPersonAddressCountryCodeKey)

    Note: country code left out

    values.append(s["kABPersonAddressStreetKey"]!! as NSString)
    values.append(s["kABPersonAddressCityKey"]!! as NSString)
    values.append(s["kABPersonAddressStateKey"]!! as NSString)
    values.append(s["kABPersonAddressZIPKey"]!! as NSString)
    values.append(s["kABPersonAddressCountryKey"]!! as NSString)
    values.append(s["kABPersonAddressCountryCodeKey"]!! as NSString)

    let dict = CFDictionaryCreate(kCFAllocatorDefault, keys, values, 5, &kCFCopyStringDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks)

    let scanned = ABUnknownPersonViewController()

    let identifier = ABMultiValueIdentifier()

    ABMultiValueAddValueAndLabel(address, dict, kABHomeLabel, &identifier)

    ABRecordSetValue(information, kABPersonAddressProperty, address, nil)

我敢肯定有一種更簡潔的方法可以做到這一點，但這是我想出的解決方案。

 var addressComponents = [String : String]()

    if let value = s["kABPersonAddressStreetKey"] {
        addressComponents[kABPersonAddressStreetKey as String] =  value
    }

    if let value = s["kABPersonAddressCityKey"] {
        addressComponents[kABPersonAddressCityKey as String] = value
    }

    if let value = s["kABPersonAddressStateKey"] {
        addressComponents[kABPersonAddressStateKey as String] = value
    }

    if let value = s["kABPersonAddressZIPKey"] {
        addressComponents[kABPersonAddressZIPKey as String] = value
    }

    if let value = s["kABPersonAddressCountryKey"] {
        addressComponents[kABPersonAddressCountryKey as String] = value
    }

    if let value = s["kABPersonAddressCountryCodeKey"] {
        addressComponents[kABPersonAddressCountryCodeKey as String] = value
    }

    let address: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
    ABMultiValueAddValueAndLabel(address, addressComponents, kABHomeLabel, nil)
    ABRecordSetValue(information, kABPersonAddressProperty, address, nil)
