MFMessageComposeViewController shows blank white screen in iOS7

Question

there's a problem when I try to send a large recipients list (eg more than 40) using MFMessageComposeViewController. In iOS7, it will show a blank white screen for 20s or more before displaying the SMS compose view. This does not occur for iOS5 and iOS6.

Below is the existing code that I'm using,

NSArray * recipients;

for (NSIndexPath * index in selectedRows) 
{ 
   NSDictionary *dictionary = [data objectAtIndex:index.row];
   NSString *phoneNum =  [dictionary objectForKey:@"contactNum"];
   recipients = [NSArray arrayWithObjects:phoneNum, nil]];
}

MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];

if([MFMessageComposeViewController canSendText])
{
    controller.body = bodyOfMessage;
    controller.recipients = recipients;
    controller.messageComposeDelegate = self ;
    controller.wantsFullScreenLayout = NO;
    [(id)_delegate presentModalViewController:controller animated:YES];
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

Below are the output message that I received when I try to send to many.

Answer 1

I had a similar problem where I got the message in the console "

timed out waiting for fence barrier from com.apple.mobilesms.compose

The problem was that I tried in my app to add the number as a string, but because of the localization request, I have put it in a form: NSArray *recipents = @[NSLocalizedString(@"numberForRegistrationViaSms", @"")];

and

[messageController setRecipients:@[recipents]];

That didn't work for some reason but, when I put just simply, [messageController setRecipients:@[@"123456789"]]; , the SMS composer appears without any problem.

I to had the same problem then figured

controller.recipients = // should always be an array of strings.

Make sure the phone numbers you send to controller.recipients are NSString.

Answer 3

I think I maybe resolve this:

NSString *phoneStr = [NSString stringWithFormat:@"%@",... ];                                                     

MFMessageComposeViewController *aCtrl = [[MFMessageComposeViewController alloc] init];
aCtrl.recipients                      = @[phoneStr];
...

Then OK.

Answer 4

I had same problem.

• timed out waiting for fence barrier from com.apple.mobilesms.compose

• Message Cancelled

Instead of this:

    NSString *phoneNumber = @"888888888";
    [picker setRecipients:@[phoneNumber]];

Try this:

    NSString *phoneNumber = person.phoneNumber;
    [picker setRecipients:@[[NSString stringWithFormat:@"%@", phoneNumber]]];

This worked for me.
