Issue in Pushing ABPersonViewController - iphone

Question

i am having trouble in pushing ABpersonViewController when the name is from user added then everything works perfectly but when name is from default simulator entries then its not working i will explain in detail in code
-(void)showPersonViewController:(NSString *)name
{
ABAddressBookRef addressBook = ABAddressBookCreate();
NSString *string = name;
NSLog(#"%#",string);
CFStringRef cfstringRef = (CFStringRef)string;
NSArray *peoplee = (NSArray *)ABAddressBookCopyPeopleWithName(addressBook, cfstringRef);
NSLog(#"%#",peoplee);
// 1ST QUESTION when contact is from defalut contact nslog is null but when from user added then it has value I dont understand why this is happening
if ((peoplee != nil) && [peoplee count])
{
ABRecordRef person = (ABRecordRef)[peoplee objectAtIndex:0];
ABPersonViewController *picker = [[ABPersonViewController alloc] init];
picker.personViewDelegate = self;
picker.displayedPerson = person;
picker.allowsEditing = YES;
[self.navigationController pushViewController:picker animated:YES];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Could not find Appleseed in the Contacts application"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:nil];
[alert show];
}
CFRelease(addressBook);
}

I replaced your code of converting NSString To CFStringRef :
This is if you are using ARC:
CFStringRef cfstringRef = (__bridge_retained CFStringRef)string;
But it seems you are not, so for Non ARC:
CFStringRef cfstringRef = (CFStringRef)string;
-(void)showPersonViewController
{
ABAddressBookRef addressBook = ABAddressBookCreate();
NSString *string = #"Appleseed";
CFStringRef cfstringRef = (CFStringRef)string;
NSArray *peoplee = (NSArray *)ABAddressBookCopyPeopleWithName(addressBook, cfstringRef);
NSLog(#"%#",peoplee); // does not print null if you have Appleseed as your contact
if ((peoplee != nil) && [peoplee count])
{
ABRecordRef person = (ABRecordRef)[peoplee objectAtIndex:0];
ABPersonViewController *picker = [[ABPersonViewController alloc] init];
picker.personViewDelegate = self;
picker.displayedPerson = person;
// Allow users to edit the person’s information
picker.allowsEditing = YES;
[self.navigationController pushViewController:picker animated:YES];
}
else
{
// Show an alert if "Appleseed" is not in Contacts
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Could not find Appleseed in the Contacts application"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:nil];
[alert show];
}
CFRelease(addressBook);
}
