Question

I am trying to set a custom background image on my tabbar. I have image named “tabbarBack.png”, with size of 640×92. In my code I am setting it like this.

[[[self tabBarController] tabBar] setBackgroundImage:[UIImage imageNamed:@"tabbarBack.png"]];

When I test it on device the tabbar is twice bigger than it should be?
Any help?

Kind regards

NSAddict’s comment: Rename your image to [e-mail]. This is called pixel doubling for the Retina Display.

Without the @2x iOS doesn’t know that it should apply a scale factor and it will be used as it is and though it should be halved.

So a hack is:

[[[self tabBarController] tabBar] setBackgroundImage:[UIImage imageNamed:@"[e-mail]"]];

In reality there should be

• tabbarBack png (45 px or so)
• [e-mail]

so you say only

[[[self tabBarController] tabBar] setBackgroundImage:[UIImage imageNamed:@"tabbarBack.png"]];
