UIWebView example code for in-app browser?

Anyone have some sample cod开发者_运维问答e for an in-app browser that they would like to share?

I am looking to add a browser view in my app that is pushed and includes a toolbar with four buttons: back, forward, stop/refresh and actions. However, I'd like to show somewhat transparent and none-tapable buttons when you can't go forward or back, and also have the stop/refresh button show the appropriate icon when it's loading and done loading?

My issue is currently that I cannot get "blanked out" back and forward that cannot be tapped if you cannot go back in the web history. Also, how do I change out the stop icon with the refreshing icon when the view is loading?

For tool bar items, simply set "item.enabled = webview.canGoForward;" (or canGoBack). To change the refresh/stop button you can set item.customView if you want to use a progress view or some such, otherwise if you just want to use a static image you can set item.image. All this is in the documentation as well.
