问题 I have a UIWebView that uses a fixed position header. When the ViewController that contains the UIWebView is the initial view, there is no problem with the fixed position divs. When I display that same ViewController through a Modal segue, that's when the problem occurs.

Now I need to check if the request comes from the web app or the native app. To do this I have two possibilities: First solution: Modify URL and check URL on server side: @IBOutlet var WebView: UIWebView! override func viewDidLoad() { super.viewDidLoad() loadWebPage() } func loadWebPage() { let url = NSURL(string: "http://localhost:8888

问题 I'm trying to open a Webarchive stored in a Core Data database. The Core Database was created on a Mac and filled with some Webarchive by using a WebView. Now I want to display these WebArchives in the UIWebView in iOS. The problem is that I don't know how to do that.
