我现在能够从peoplePickerNavigationController
成功访问和获取数据,但我想这样做是有联系人的电子邮件地址进行访问,那么当按下联系人姓名驳回了模态窗口。
情景:
"Button is clicked to add a contact
AddressBook Modal Window slides into view
Name of Contact is pressed
If available, the contact's email address is stored in an array
Dismiss modal window"
我当前的代码包括:
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
ABMultiValueRef container = ABRecordCopyValue(person, property);
CFStringRef contactData = ABMultiValueCopyValueAtIndex(container, identifier);
CFRelease(container);
NSString *contactString = [NSString stringWithString:(NSString *)contactData];
CFRelease(contactData);
NSLog(@"Value is: %@", contactString);
[self dismissModalViewControllerAnimated:YES];
return NO;
}
解决方案
下面是我做什么。
if(property == kABPersonEmailProperty) {
CFTypeRef prop = ABRecordCopyValue(person, property);
CFIndex index = ABMultiValueGetIndexForIdentifier(prop, identifierForValue);
NSString *email = (NSString *)ABMultiValueCopyValueAtIndex(prop, index);
...
CFRelease(prop);
[email release];
}
