The only Radio app on CodeCanyon that supports iPhone, iPad, Retina and iPhone 5!
Very easy to customise, fully commented. Just switch the images and URLs and you’re good to go.
This is my own personal app and is currently live in the AppStore which you can see here: https://itunes.apple.com/gb/app/gamer-fm/id466650414?mt=8 (please don’t copy and re-upload!)
Features:
• Awful Design (I’m a coder not an artist) but easy to edit 
• Tabbar interface which can support extra pages.
• iAd Support, simply uncomment and go.
• Multi-station support add as many as you like, will support hundreds.
• Image or text based buttons, up to you, overwrite mine for a unique look.
• Supports popular internet radio streams (I haven’t found anything that hasn’t worked yet).
• Volume slider.
• Custom label which shows which station you’re currently playing.
• Changeable play and pause buttons.
• Fully universal with a native .xib for iPad, no fancy programming here!
• Code based iPhone 5 support which adjusts the table automatically depending on the device recognised so no need to do anything twice for iPhone 5 or mess with AutoLayout constraints.
• Social media links and inbuilt email form.
• Works on Wifi or 3G and is relatively data friendly.
• Plays audio in the background.
• Support for custom fonts.
• Guaranteed Apple Approved code (see the link above. Please note that major changes or inappropriate content may affect approval).
For a fee I can even customise it for you so please don’t hesitate to contact me.
