var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);

It works perfectly on Fb app but not twitter app. Please help.

Use this one :

Download origin from : this is part of visual js game engine project

When you ask "detect webview" what you really mean. Are you using native app with webView (some hybrid framework - phone gap) or you just wanna to detect some iframe or adds intro html doc ?

May i can figure . You want to know is it simple browser come to page or some native app. If you even use this like some prevent feature than is it a bad idea in security aspect. UserAgent data is only string easy for manipulation.

"Fb app ... twitter app" ?!
