2,052 PointsUISplitViewController in Xcode
Hey Guys, Im in Xcode with a split view controller and all my code is great without any issues, and i have a home screen before my split view, and when i run the app, and click on a link to go to the split view, it crashes and comes up with the main.main file, and i checked all the links in the Main.Storyboard and they are all good, nothing wrong there, i added an exemption break point, that didn't reveal anything but the same main,main file, and than i tried resetting the Simulator, and still, the same problem, does anyone know where i went wrong or what i can do to try and fix my problem?

42,016 PointsOk, then there is your problem right there reason: 'Application tried to present a Split View Controllers modally Basically you need to make the split view controller the root view controller before presenting it using something like
self.window.rootViewController = self.splitViewController;
Stephan Kokkas
2,052 PointsSo, im not able to have say a home screen before the split view controller? Stone Preston
Stone Preston
42,016 Pointsno you should be able to, you just have to change the root view controller whenever you want to show that split view controller. However ive never worked with one before, so this all based on assumption.

42,016 Pointsno problem. Hope you get it working.

42,016 Pointsthere is probably an error message that gets logged to your console after the crash. can you post that?
