解析iPhone應用內存洩露

應用代碼如下：
用來過濾和篩選

- (long)personRecord:(ABRecordRef)paramPerson{

    if(paramPerson == nil){

        NSLog(@"The given Person is Null");
    }

    ABMutableMultiValueRef emails = ABRecordCopyValue(paramPerson, kABPersonEmailProperty);
    if(emails == nil){

        return 0;
    }

    NSLog(@"%ld",ABMultiValueGetCount(emails));
    // return (ABMultiValueGetCount(emails));

    return (ABMultiValueGetCount(emails));
}

但是當解析的時候出現：

怎麼解決這個Leak？

最佳回答：

你是從ABRecordRef中獲得了一份復制的object.釋放一下

修改為如下方法：

- (long)personRecord:(ABRecordRef)paramPerson
  {

    if(paramPerson == nil)
    {

        NSLog(@"The given Person is Null");
    }

    ABMutableMultiValueRef emails = ABRecordCopyValue(paramPerson, kABPersonEmailProperty);
    if(emails == nil)
    {

        return 0;
    }

    NSLog(@"%ld",ABMultiValueGetCount(emails));
    // return (ABMultiValueGetCount(emails));

    long count = ABMultiValueGetCount(emails);
     CFRelease(emails);
     return count;
}
