Mac OS X Cocoa multiview application navigation

Question

I\'ve already spent 2 full days trying to figure out how to use NSViewControllers in order to create a multiview application.

Here is what I do.

This isn't much of an answer at the moment, however I have some concerns about your code that I wanted to work through with you.

• Are you sure you have connected the outlets and actions in Interface Builder. Please verify this.

• You don't need mainWindow as there is already a window property that points to the main window (verify this in Interface Builder). Also this looks wrong:

  @synthesize mainWindow = mainwindow;
                               ^
                               W
  

  So dump that and just use the existing window outlet provided by Xcode.

• Don't re-create the view controllers if they already exist:

  if (self.secondViewController == nil)
  {
      self.secondViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController"
                                                                         bundle:nil];
  }
  self.window.contentView = self.secondViewController.view;
