MFMessageComposeViewController first alloc takes seconds

Question

I am trying to show an MFMessageComposeViewController with the following code:

controller = [[MFMessageComposeViewController alloc] init];

if([MFMessageComposeViewController canSendText])
{
    controller.body = [NSString stringWithFormat:@"%@%@%@", itemString, amountString, callTimeString];   
    controller.recipients = [NSArray arrayWithObject:@"12345678"];
    controller.messageComposeDelegate = self;
    [self presentModalViewController:controller animated:YES];
} 

The problem is when I press the button to bring up the MFMessageComposeViewController, the alloc takes a few seconds. I have tried moving the alloc line to my viewDidLoad method, however this just moves the problem and I end up waiting a few seconds for the view to load.

Is there any method to speed up the alloc and showing of my MFMessageComposeViewController or use a delegate method or something?

Thanks.

Well, what you are doing seems about right. You are not doing anything wrong. Check this - Can't set recipients of MFMessageComposeViewController? & the link attached in the answer

I had a similar problem, check out my answer here: I need a callback when MFMessegeComposeViewController finally loads

For me it wasn't the alloc taking too long, it was the presentModalViewController of the MFMessageComposeViewController, which blocks on Apple's code on the UI thread, so no way to background it except for throwing up your own progress view.
