ABRecordRef存儲陣列

Question

我們如何存儲和訪問ABRecordRef的列表，以便我們可以在另一個課程中使用它，以後再使用？

Answer 1

您可以從ABRecordRef類型的記錄中獲得recordId從 addressBook然後將其轉換爲NSString。儲存於NSUserDefaults

當你想獲取該記錄......

獲取該recordId從NSUserDefaults，將其轉換爲整數

然後用

ABRecordRef myRecord = 
ABAddressBookGetPersonWithRecordID(addressBook, recordId); 

所以，你會得到您之前保存的記錄。

Answer 2

試試這個：

ABAddressBookRef addressBook = ABAddressBookCreate(); 
ABRecordRef person = ABRecordGetRecordID(1); // Or whatever you're using to get the record. 

// do this for each piece of information you need: 
NSString *firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); 
NSString *lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty); 

// Get your receiving dict ready: 
NSMutableDictionary *personDict = [NSMutableDictionary dictionary]; 

// then test them for a value (don't want nil values in the dictionary) 
// Add each value as you test it. 
if (firstName) { 
    [personDict setObject:firstName forKey:@"FistName"]; 
} 
if (lastName) { 
    [personDict setObject:lastName forKey:@"LastName"]; 
} 

// Add the personDict to NSUserDefaults: 
[[NSUserDefaults standardDefaults] setObject:personDict forKey:@"MyPersonsDictionary"]; 

// Clean up after yourself: 
[firstName release]; 
[lastNmae release]; 

這應該是它。
