How to update a UI label from a non UI thread in iOS

Question

I am new to iOS development, I have plain objective -c class \"MoneyTimer.m\" for running timer, from there i want to update the an UI label with the changing value of timer.

Answer 1

The proper way is this:

- (void) countUpH  {
   sumUp = sumUp + rateInSecH;
   //Accessing UI Thread
   dispatch_async(dispatch_get_main_queue(), ^{

   //Do any updates to your label here
    yourLabel.text = newText;
   });
}
