ios - swift : Issue with accessing CFDictionaryRef for ABAddressBookRef

Question

我在 ObjC 中收集了联系人的地址信息，

ABMultiValueRef addressProperty = ABRecordCopyValue(contactRef, kABPersonAddressProperty);
CFDictionaryRef dict = ABMultiValueCopyValueAtIndex(addressProperty, 0);
   if(dict)
   {
     NSString *street = (NSString *)CFDictionaryGetValue(dict, kABPersonAddressStreetKey);
   }

因此，等效的 Swift 代码是，

let addressProperty : ABMultiValueRef = ABRecordCopyValue(contactRef, kABPersonAddressProperty).takeUnretainedValue() as ABMultiValueRef

    if let dict : CFDictionaryRef = ABMultiValueCopyValueAtIndex(addressProperty, 0).takeUnretainedValue() as? CFDictionaryRef
    {
     let street = CFDictionaryGetValue(dict,kABPersonAddressStreetKey)
    // Stuck here, among  CFString!, UnsafePointer<Void>, CFDictionaryRef ...
    }

我将如何获取街道和其他类似信息？

Answer 1

你可以使用NSDictionary来代替吗？ (未测试)

if let dict : NSDictionary = ABMultiValueCopyValueAtIndex(addressProperty, 0).takeUnretainedValue() as? NSDictionary
{
 let street = dict[kABPersonAddressStreetKey]
}
