MFMessageComposeViewController not working

问题:

I have a simple method that gets one argument and then sends a message. It is not working.

Code:

- (void)sendSMS:(NSString *)text {     MFMessageComposeViewController *viewController = [[MFMessageComposeViewController alloc] init];     viewController.body = text;     viewControllerM.mailComposeDelegate = self;     [self presentViewController:viewController animated:YES completion:nil]; } 

What's wrong?

回答1:

You need to set the delegate:

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];     if([MFMessageComposeViewController canSendText])     {         controller.body = @"YO";         controller.recipients = [NSArray arrayWithObjects:@"5625555555", nil];         controller.messageComposeDelegate = self;          [self presentViewController:controller animated:YES completion:nil];     }
