Can't see "Button Pressed" on console

I followed all instructions in video and confirmed that the button was connected to the IBAction (i.e when I hovered, the button became highlighted). Then in my ViewController.m I added the NSLog statement. When I ran the app, the iOS Simulator was totally black and stayed black. Not until I hit "Stop" to stop running the app did I see on the Simulator an icon in the upper left section labeled "CrystalBall" with a Safari icon at bottom. When I clicked on the "CrystalBall" icon I saw the correct page: "It is decidedly so" with the blue "Predict" button. At this point the app had stopped running. Consequently, nothing ever appeared in the console. Any thoughts on what I need to do? Thank you!!!!

Hi Marilyn,

Here's what I have in my 'buttonPressed' method. Hope this helps - 

- (IBAction)buttonPressed {

    self.predictionLabel.text = [self.predictions objectAtIndex:3];
    NSLog(@"Button Pressed");

}
