MFMessageComposeViewController shows blank white screen in iOS7 - iphone

Question

there's a problem when I try to send a large recipients list (e.g 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.
timed out waiting for fence barrier from com.apple.mobilesms.compose

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.

Answer 2

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:
//must initiate new NSString object
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.

Answer 5

The problem has been resolved in iOS 7.0.3.
