How to get back to original ViewController after pressing "Back" button
I'm developing a chat app and I am having trouble in reopening the same view controller after pressing "Back" button.
I have a ViewController that opens a chat interface, that on clicking a button launches the IPhone's default messaging application.
I use the below code in my ViewController to get the launched messaging application to quit when I press the "Back" button.
-(void)back:(id)sender {
if (self.presentingViewController!= nil) {
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil];
}
}
Now, when I launch the messaging application, click on "Continue" and once I have sent the text, I push back to my VC with the following code.
[self dismissViewControllerAnimated:YES completion:nil];
That works fine, but when I press the "Back" button, instead of popping back to the ViewController, I get taken to the App's home screen. I want to get back to my ViewController after I press the "Back" button.
Any ideas on how I can do this?
A:
You should do something like:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self performSegueWithIdentifier:@"YourSegueID" sender:nil];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"YourSegueID"]) { be359ba680
