Step 2: Now xCode will create all minimum required files for you. Open “InAppBrowserViewController.xib” file from left panel and add one textfield to enter url. Add one button next to added text field and give it title as “Go”. So we will code on tap of this button to load url in browser. Now add UIWebView to this view as shown in below image.

@interface InAppBrowserViewController : UIViewController
IBOutlet UITextField *txtUrl;
IBOutlet UIWebView *webView;
