Используйте строковую переменную в сообщении MFMailCopose

Question

- (IBAction)sendButton:(id)sender { 

NSString *locationFormatter = [NSString stringWithFormat:@"https://maps.google.com?saddr=Current+Location&daddr=%f,%f", self.locationManager.location.coordinate.latitude, self.locationManager.location.coordinate.longitude]; 

if ([MFMailComposeViewController canSendMail]){ 

    MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc]init]; 
    mailComposer.mailComposeDelegate = self; 
    [mailComposer setSubject:@"Google Maps Directions"]; 
    [mailComposer setToRecipients:@[@"castro.michael87@gmail.com"]]; 
    [mailComposer setMessageBody:@"Google Maps Url:locationFormatter" isHTML:NO]; 

    // Display Mail Composer 
    [self presentViewController:mailComposer animated:YES completion:nil]; 
} 

Как вставить строку locationFormatter в MessageBody? Я надеялся, что это будет работать:

[mailComposer setMessageBody:@"%@",locationFormatter isHTML:NO]; 

Answer 1

Try:

[mailComposer setMessageBody:[NSString stringWithFormat:@"Google Maps Url:%@", locationFormatter] isHTML:NO];
