iphone - UIWebView opens non-related site -

I have opened a website using UIWebview , but sometime when I clicked on a button Clicked or linked, it automatically calls a non-related website like when I click on a Facebook link, it goes straight to the App Store and asks for the Facebook installation process (even if the Facebook app is installed , Even though) I can not go back to my app after that You have to get out of the house and reopen it again.

• Why is this app growing in the store, even though the Facebook app is already installed?
• Is there a possibility to add an option back to the App Store?

  Code:

    Webview. Escrow view Desertation Right = UISCroll Scene Overview; [Load webview load: [NSRR request request with url: [NSW URL Youth String: @ "Web site URL"]]]; Webviews.scalesPageToFit = Yes;    
   
   
   To control whether a webview is open or not, you can use the UIWebView representative (Check Start ... LoadLoadWithRequest: ...)
