Set background image for UIToolBar

Question

I've seen a lot of people doing this:

[[UIToolbar appearance] setBackgroundImage:toolBarImage forBarMetrics:UIBarMetricsDefault];

For me it doesn't work, because my App crashes and says:

-[_UIAppearance setBackgroundImage:]: unrecognized selector sent to instance 0xab8fe80

I already researched and found out that UIAppearance is only available since ios 5, but my simulator is 6.1 and my iPhone too. Also I did this with the NavigationBar which works.

Hope you can help me :) Thanks a lot!!

This worked for me:

UIImage* toolbarImage = [UIImage imageNamed: @"toolbar_background.png"];
[[UIToolbar appearance] 
    setBackgroundImage: toolbarImage 
    forToolbarPosition: UIToolbarPositionAny
    barMetrics: UIBarMetricsDefault];

It's not necessary to use the appearance proxy, you can set background image to the specific toolar: `[yourToolbar setBackgroundImage: toolbarImage forToolbarPosition: UIToolbarPositionAny barMetrics: UIBarMetricsDefault]` – vahotm Sep 11 '17 at 16:40

Check this:

If The UIToolbar is contained within a ViewController.

You cannot change the UIToolbar within AppDelegate if the UIToolbar is contained in a ViewController.

Also see here: IOS 5 unrecognized selector send at appearance proxy for setBackgroundImage

You should call this method in your app delegate implementation file in the didfinishlaunchingwithoptions: method
