is possible from a button with link to open the app store ?
the ShowURL(MyUrl) give me always error page invalid.
If i make copy paste on my browser the link working fine.
link is like that
Launch iTunes on your computer.
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.
In your application, create an NSURL object with the copied iTunes URL, then pass this object to UIApplication’ s openURL: method to open your item in the App Store.
If you want to launch iTunes from a webpage for a particular iOS application, all you need to do it take the URL (right click on the App icon in the App store and copy it)
then change the HTTPS:// to itms://
this will then launch iTune on the users computer, and take them to the store page for that application
example :
itms://itunes.apple.com/us/app/calcds/id990331755?mt=8
