The iPhone/iPad will automatically recognize an AppStore URL if you just:

- (IBAction)OpenAppInAppStore {

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.apple.com/us/app/wolframalpha/id334989259?mt=8"]];

}

or if you open any URL that has "itms://" and only on the device

1. Launch iTunes on your computer.
2. Search for the item you want to link to.
3. Right-click or control-click on the item's name in iTunes, then choose "Copy iTunes Store URL" from the pop-up menu.
4. Open the modified URL using an NSURL object and the -[UIApplication openURL] method.

Read Technical Q&A QA1629. They also offer a method how you can add your iTunes Affiliate link without redirecting from your app to safari to the appstore
