How can I display a splash screen for longer on an iPhone?

Question

How can I display a splash screen for a longer period of time than the default time on an iPhone?

Answer 1

Read the Apple iPhone Human Interface Guidelines (HIG). The "splash screen" isn't supposed to be for branding or displaying a logo, it's supposed to look like the default condition of the app so it appears to start up quickly.

Making it stay there for longer would be a violation of the HIG.
