Hi friends, I ran into a problem while creating a MAC application. I have two view controllers. when I click the button that fits into the first view controller application, replace the view using the code below
- (IBAction)gotoEmployeeView:(id)sender { delegate = (AppDelegate *)[[NSApplication sharedApplication]delegate]; secondViewController *employeeVC = [[secondViewController alloc]initWithNibName:@"secondViewController" bundle:nil]; [[delegate.window.contentView animator] replaceSubview:self.view with:secondVC.view]; secondVC.view.frame = ((NSView *)delegate.window.contentView).bounds; }
I now have one button, and I set the click event for this button on the second screen. below id button click event
- (IBAction)btnClicked:(id)sender { NSLog(@"clicked"); }
and when I clicked on it, the application crashed. and get below error
