問題與警報視圖，'委託'未申報的錯誤

這可能是一個學校的男孩錯誤，但我想嵌入一個UIAlertView之後有人選擇一個不屬於地址的peoplePickerNavigationController中的聯繫人屬性。我做錯了什麼是'代表'未申報的錯誤！有人能夠從概念上告訴我爲什麼這不起作用，因爲我已經將自己變成了UIAlertViewDelegate並且做了正確的事情！在此先感謝:-)問題與警報視圖，'委託'未申報的錯誤

- (BOOL) peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker 
    shouldContinueAfterSelectingPerson:(ABRecordRef)person 
     property:(ABPropertyID)property 
      identifier:(ABMultiValueIdentifier)identifier { 
UIAlertView *alert; 
if (property == kABPersonAddressProperty) 
    NSLog(@"ZOMG YOU PRESSED FOR AN ADDRESS!!"); 
else { 
    alert = [UIAlertView alloc]; 
    [alert initWithTitle:@"Invalid Address" message:@"Please pick an address from a contact": delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
    [alert release]; 
} 

[self dismissModalViewControllerAnimated:YES]; 
return NO; 
}

你已經有了一個額外的：這裏 -
