如何獲取系統生成的地址簿的警報查看

Question

我正在致力於地址簿中的我的應用程序，我只想獲得一個alertview訪問Address.How我可以顯示系統生成的警報訪問addressBook？

Answer 1

如果你想顯示給用戶的自定義信息，要求允許使用他們的聯繫人或地址簿，而不是上面顯示一個默認的時候，你需要這個字段添加到您的Info.plist文件：

NSContactsUsageDescription

// Check the authorization status of your application for Address Book 
-(void)checkAddressBookAccess 
{ 
    switch (ABAddressBookGetAuthorizationStatus()) 
    { 
      // Update our UI if the user has granted access to their Contacts 
     case kABAuthorizationStatusAuthorized: 
      [self showAddressBook]; 
      break; 
      // Prompt the user for access to Contacts if there is no definitive answer 
     case kABAuthorizationStatusNotDetermined : 
      [self requestAddressBookAccess]; 
      break; 
      // Display a message if the user has denied or restricted access to Contacts 
     case kABAuthorizationStatusDenied: 
     case kABAuthorizationStatusRestricted: 
     { 
      UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Warning" 
                  message:@"You have not granted access to your contacts or you have revoked it earlier." 
                  delegate:nil 
                cancelButtonTitle:@"OK" 
                otherButtonTitles:nil]; 
      [alert show]; 
     } 
      break; 
     default: 
      break; 
    } 
} 

// Prompt the user for access to their Address Book data 
-(void)requestAddressBookAccess 
{ 
    TF_Message_View_Controller * __weak weakSelf = self; 

    ABAddressBookRequestAccessWithCompletion(self.addressBook, ^(bool granted, CFErrorRef error) 
              { 
               if (granted) 
               { 
                dispatch_async(dispatch_get_main_queue(), ^{ 
                 [weakSelf showAddressBook]; 

                }); 
               } 
              }); 
}

如果你想顯示警報請求許可，您可以使用下面的代碼

該代碼可以使用聯繫人的框架，它僅適用於iOS 9.0或更高版本

- (void)checkContactStoreAccess { 
    self.contactsStrore = [[CNContactStore alloc] init]; 

    switch ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts]) { 
     case CNAuthorizationStatusAuthorized: { 
      [self fetchContactsFromContactStore]; 
      break; 
     } 
     case CNAuthorizationStatusNotDetermined:{ 
      [self requestContactsAccess]; 
      break; 
     } 
     case CNAuthorizationStatusDenied: 
     case CNAuthorizationStatusRestricted:{ 
      //show info that access denied for contact and redirect user to settings with 
      [UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]]; 
     } 
    } 
} 
- (void)requestContactsAccess { 
    typeof(self) __weak weakSelf = self; 
    [self.contactsStrore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) { 
     [weakSelf fetchContactsFromContactStore]; 
    }]; 
}
