Question

我正在处理一个应用程序，该应用程序允许用户从电话的地址簿中选择联系人，并在UITableView中显示该联系人。我使用以下代码来接收联系人;

-(IBAction)pickPhoneContacts:(id)sender //opens phone's address book
{
   ABPeoplePickerNavigationController *picker =

   [[ABPeoplePickerNavigationController alloc] init];

   picker.peoplePickerDelegate = self;

   [self presentViewController:picker animated:YES completion:nil];

}

  //called when user presses the cancel button in the Address book view controller
  - (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController*)peoplePicker

 {
    [self dismissViewControllerAnimated:YES completion:nil];
 }


   //called when user pics up a contact from the phone's address book

   - (BOOL)peoplePickerNavigationController:

  (ABPeoplePickerNavigationController *)peoplePicker

  shouldContinueAfterSelectingPerson:(ABRecordRef)person {


  [self displayPerson:person]; //calls displayPerson:(ABRecordRef)person to show contact's information in the app

  [self dismissViewControllerAnimated:YES completion:NULL];

   return NO;
}


//called when the user selects the property of the contact. This method will not be called in the  app but included to complete the implementation of the protocol


- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)

peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person

 property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
 {
   return NO;
 }

   //Displays the contact name and the contact's primary number in the app's text fields (add contact view controller)
 - (void)displayPerson:(ABRecordRef)person
 {
    NSString* name = (__bridge_transferNSString*)ABRecordCopyValue(person,kABPersonFirstNameProperty); //Extracts the contact's first name from address book & assigns it to a string value


  self.contactNameTextFiled.text = name;

  NSString* phone = nil;

  //Extracts the first phone number among multiple contact numbers from address book & assigns it to a string value
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person,kABPersonPhoneProperty);

if (ABMultiValueGetCount(phoneNumbers) > 0)
{
    phone = (__bridge_transfer NSString*)

    ABMultiValueCopyValueAtIndex(phoneNumbers, 0);

}
else
{
    phone = @"[None]";
}

self.primaryNumberTextField.text = phone;

CFRelease(phoneNumbers);

}

现在的任务是，一旦用户从地址簿中找到联系人，ABPeoplePickerNavigator就会解散，并且MFMessageComposeViewController应立即显示默认消息和选择的联系号码。因此，应用程序的用户应该向所选择的联系人号码发送消息。我在消息撰写视图控制器中使用了以下代码;

-(void)sendSMS
{
   MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
   if([MFMessageComposeViewController canSendText])
   {
      controller.body = @"Test Message";
      controller.recipients = [NSArray arrayWithObjects:@"111222333", nil];
      controller.messageComposeDelegate = self;
       [self presentViewController:controller animated:YES completion:nil];

   }

}

现在请帮助我在哪里调用此方法，以便一旦ABPeoplePickerNavigationController解除，MFMessageComposeViewController就会出现。

Answer 1

使用新函数dismissViewControllerAnimated：completion：所以在完成后调用发送短信，因为我编辑了你的代码。

- (BOOL)peoplePickerNavigationController:

  (ABPeoplePickerNavigationController *)peoplePicker

  shouldContinueAfterSelectingPerson:(ABRecordRef)person {


  [self displayPerson:person]; //calls displayPerson:(ABRecordRef)person to show contact's information in the app

//  [self dismissViewControllerAnimated:YES completion:NULL];
    [self dismissViewControllerAnimated:YES completion:^{
        [self sendSMS];
    }];

   return NO;
}

Answer 2

当您解散时，将地址控制器的动画设置为“否”

    [self dismissViewControllerAnimated:NO completion:nil];

Answer 3

尝试

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person;

呼叫

-(void)sendSMS

in dismissViewControllerAnimated：completion：completion handler。

[self dismissViewControllerAnimated:YES completion:{[self sendSMS]}];

希望这会有所帮助。

Answer 4

<。>文件中的

MFMessageComposeViewController * controller;

ABPeoplePickerNavigationController * picker;

并且在.m中就这样做了

-(void)sendSMS中的

{ //其他代码

 [picker presentViewController:controller animated:YES completion:nil];

}

用户从ABPeoplePickerNavigationController中选择联系人后立即显示MFMessageComposeViewController
