How to launch App Store from my iPhone application?

This is easy. Just follow the steps below and you will be over in less then minute.

• Launch iTunes on your Mac.
• Search for the item you want to link to.
• Right-click or control-click on the item’s name in iTunes, then choose “Copy iTunes Store URL” from the pop-up menu.
  
• The returned URL is an itunes.apple.com link. However, iPhone requires phobos URLs for direct linking to the App Store.
• Therefore, you must replace itunes with phobos in the returned URL.
• Open the modified URL using an NSURL object and the -[UIApplication openURL] method.

- (IBAction)appStoreLink {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301349397&mt=8"]];
}

Now when you press button linked with appStoreLink IBAction, App Store application will open and you will see Divine Office application. That’s all.
