如何僅從結果集中獲取用戶名

Question

選擇聯系人的Twitter詳細信息時，如何僅從通訊簿獲取用戶名值

if ( property == kABPersonSocialProfileProperty) {

        ABMultiValueRef multi = ABRecordCopyValue(person, property);


        for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) {

            CFStringRef socialLabel = ABAddressBookCopyLocalizedLabel(ABMultiValueCopyLabelAtIndex(multi, identifier));

            CFStringRef social = ABMultiValueCopyValueAtIndex(multi, i);

            NSDictionary* personaddress =(NSDictionary*) ABMultiValueCopyValueAtIndex(multi, i);        

            NSString*twitterdetails = [personaddress valueForKey:(NSString *)kABPersonSocialProfileServiceTwitter];
            NSLog(@"%@ twitterdetails",twitterdetails);  


            NSString *aString = (NSString *)social;


            NSLog(@"%@ aString",aString);
        }

我得到如下結果

{
    service = twitter;
    url = "http://twitter.com/manoas2136";
    username = manoas2136;
} aString

請告訴我如何從上述結果集中獲取用戶名

Answer 1

試試這個代碼

  NSDictionary* personalDetails = [NSDictionary dictionaryWithDictionary:(NSDictionary*)ABMultiValueCopyValueAtIndex(multi, i)];
  NSString* aString = [personalDetails valueForKey:@"username"];
  NSLog(@"%@ aString",aString);

結果manoas2136 aString

您將NSDictionary值轉換為字符串，以便將NSDictionary的所有結果匯總為NSString，因此您可以使用valueForKey僅提取用戶名：

我已經嘗試過這種方式來從iPhone聯系人列表中獲取Twitter地址。 而且效果很好..

ABMultiValueRef multi = ABRecordCopyValue(person, kABPersonSocialProfileProperty);

for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) 
{

    NSDictionary* personalDetails = [NSDictionary dictionaryWithDictionary:(NSDictionary*)ABMultiValueCopyValueAtIndex(multi, i)];
    NSLog(@"%@",personalDetails);

    NSString* aString1 = [personalDetails valueForKey:@"username"];
    NSLog(@"%@ aString",aString1);
    Twitter.text = [personalDetails valueForKey:@"username"];
}
//get Twitter Address end....
