Breaking Out of Progress Bar Thread

[ttseng]

I'm using the progress bar to count down to 0 – once the timer is finished, I want to trigger a method in my View Controller.

Do you have any sample code that will break out of your thread to call a function on the main queue?

Here is my current code:

    [MCUtil runOnAuxiliaryQueue:^{
        while(currentTime < timeLimit && self.isRecording){
            [MCUtil runOnMainQueue:^{
                currentTime += 0.01;
                self.audioProgress.percentage = (float)currentTime/timeLimit;
            }];
            [NSThread sleepForTimeInterval:0.01];
        }
        NSLog(@"reached end of time limit");
        // calling method here has delay?
    }];
