Fixed Background for iPhone app using Storyboard

Can't seem to find a way to fix a graphic - a light graphic that would remain static as the user navigates from scene to scene. Have been combing forums for a few days, but most answers point to MainWindow.xib, which isn't generated for a storyboard project. Would appreciate any advice.

Here’s what I was able to cobble together thanks to advice from @Max. Like I said, very new to this, so if this code needs tuning please leave a comment so I don’t lead others astray.

Add the image to the app’s main window in the AppDelegate’s didFinishLaunchingWithOptions method :

UIImageView *myGraphic = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myGraphic.png"]];
[self.window.rootViewController.view addSubview: myGraphic];
[self.window.rootViewController.view sendSubviewToBack: myGraphic];

Then, to make your views transparent so the background shows through - in your viewController class/es, add to viewDidLoad method:

self.view.backgroundColor = [UIColor clearColor];

(And note if you try to decrease the transparency through the alpha property for the view via the Attributes Inspector, it will make everything transparent on that view -buttons, etc - that’s why it needs to be done programmatically.)

Sure, it’s not thoroughly tested. But for now it’s working and it’s a thing of beauty. Thanks all.

If you're going to tackle this programmatically, within each view controller, set:

[[self view] setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"background.png"]]];

in viewDidLoad

I'm sure some tweaking would allow you to apply this principle throughout the program from the app delegate, or by using a singleton.

Using this solution, though, you're still going to have to make some method call within each view controller where you want this style applied.

You can try to manually add UIImageView to your window and then set 0 background transparency for all other views.

One way to do it -- it may not be the best -- can be that you subclass a UIView, and set the UIView instance in all of your viewControllers in the storyboard an instance of your cutomized UIView class, which contains your graphic as a background.
