ios : sms message composer not showing - ios

Question

I have a UITableViewController presenting a list of contacts, when the user selects a row, it'll show a UIActionSheet to ask the user an action (call, send sms...).
The user selects an action, and that first UIActionSheet will show another UIActionSheet which contains phone numbers.
The user selects a phone number, and this should show the SMS message composer.
The problem is that when the user selects a phone number, the message composer view doesn't show (just a black screen), and I receive the MessageComposeResultCancelled in the MFMessageComposeViewController's didFinishWithResult.
Which generates this warning "Warning: Attempt to dismiss from view controller while a presentation or dismiss is in progress!"
How can I correctly call and show the SMS message composer?
(this works perfectly if I call it directly when the user selects a row in the list with didSelectRowAtIndexPath)
Here's some code :
1- call to first UIActionSheet in didSelectRowAtIndexPath method :
UIActionSheet *popupQuery;
...
[popupQuery showInView:self.view];
2- call to second UIActionSheet in clickedButtonAtIndex method :
UIActionSheet *popupQuery2;
...
[popupQuery showInView:self.view];
3- from the same method, call to message composer :
[self sendSMS:#"" recipientList:[phoneNumbers objectAtIndex:buttonIndex]];
the method that shows message composer :
(void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText])
{
controller.body = bodyOfMessage;
controller.recipients = recipients;
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
}

Answer 1

solution found here : MFMessageComposeViewController shows blank/white screen
controller.recipients = [NSArray arrayWithObject:theRecipients];
theRecipients was an array containing only one element (the phone number selected)

As you don't want to try showing two modal controls in the same time, use actionSheet:didDismissWithButtonIndex: delegate method so that action sheet is hidden when you start to show messaging controller.
The following code shows composer which is not cancelled automatically.
I can see 0 at log which is the value of MessageComposeResultCancelled, only when I press Cancel button. Are you trying to make a hack by pressing send button automatically ?
MFMessageComposeViewController.h
enum MessageComposeResult {
MessageComposeResultCancelled, //0
MessageComposeResultSent, //1
MessageComposeResultFailed //2
};
MyViewController.m
-(IBAction)onButtonPressed:(id)sender {
UIActionSheet * sheet = [[UIActionSheet alloc] initWithTitle:#"Title"
delegate:self
cancelButtonTitle:#"Go out"
destructiveButtonTitle:#"Show message composer"
otherButtonTitles:nil, nil];
[sheet showInView:self.view];
}
-(void) actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText])
{
controller.body = #"body";
// controller.recipients = recipients;
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
}
-(void) messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
NSLog(#"%d", result);
[controller dismissModalViewControllerAnimated:YES];
}
