Changing tab bar height (iphone - cocoa touch)

is anyone aware of a way of adjusting the height of the tab bar on the iphone? Is开发者_如何学Python this in breach of UI guidelines?

Thanks

There is no easy way to do this as it goes against the iPhone UI guidelines. The only way to achieve such a thing is to create a custom UITabBarController-equivalent class that lays out views with a custom Tab Bar.
