iOS: Activity Indicator is not showing while calling post API - ios

Question

here is my code I written for showing activityIndicator on the navigationBar.
In my project on every view, a loader is showing it is working fine either in the middle of the screen or else on network activityIndicator or loader on navigation.
But when I am trying to call below post method, activityIndicator is not showing (in this method only it is not working.)
I tried so many ways of writing programmatically and using storyboard.
Scenario 1 : Without entering reply content/message if click on submit button then activityIndicator will appear.
Scenario 2 : If I entered any reply content/message then activityIndicator will not show.

activityIndicator.color=[UIColor blackColor];
UIBarButtonItem * barButton =
[[UIBarButtonItem alloc] initWithCustomView:activityIndicator];
// Set to Left or Right

}
else if ([jsonData objectForKey:#"message"])
{
NSString *str=[jsonData objectForKey:#"message"];
if([str isEqualToString:#"Token expired"])
{

}
}
else
{
[self->utils showAlertWithMessage:#"Something went wrong. Please try again." sendViewController:self];
}
NSLog(#"Thread-Ticket-Reply-closed");
}
}#catch (NSException *exception)
{
[utils showAlertWithMessage:exception.name sendViewController:self];
NSLog( #"Name: %#", exception.name);
NSLog( #"Reason: %#", exception.reason );
return;
}
#finally
{
NSLog( #" I am in replytTicket method in TicketDetail ViewController" );
}
}
}
So this is the problem I am facing.
What is going wrong? any solution for this?

Answer 1

use this method
[self performSelector:#selector(replyTicketMethodCall) withObject:self afterDelay:5.0];
instead of this
[self replyTicketMethodCall];
