问题描述
我正在使用 ABAddressBookGetPersonWithRecordID
来获取新的记录。但返回的值是 NULL
。我在AddressBook中有三个联系人,但它返回Null。我正在测试iOS 5模拟器上的代码。我使用的代码如下所示。
I am using the ABAddressBookGetPersonWithRecordID
in order to get the contant Record. But the value returned is NULL
. I have three Contacts in the AddressBook, but it returns Null. I am testing the code on the iOS 5 Simulator. The code which I used is given below.
for(int counter = 1;counter <= ABAddressBookGetPersonCount(addressBookRef); counter++)
{
ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBookRef, (ABRecordID)counter);
NSNumber *recordId = [NSNumber numberWithInteger:ABRecordGetRecordID(person)];
NSLog(@"record id is %@",recordId);
if (person == NULL)
{
continue;
}
else
{
[VCard generateVCardStringWithRecID:counter];
}
}
