Does App store reject icons in the app for being shiny or glossy <p>I am designing icons to include in my app and was designing them to be glossy and shiny. Then found out that app store accepts flat icons without rounded corners by doing research across internet as I did not find much information in <code>iOS Human Interface Guidelines</code> about icons. I would appreciate if anyone can direct me or provide me guidelines about designing <code>icons in app</code> as well as <code>app icon</code> for app store. I am completely new to this and like to know whether there are any limitations on <code>background images</code> and <code>images</code> used in the app as well.</p>
