uiwebview

I'm working on a browser app, and I have an address bar on top the UIWebView. On MobileSafari if you scroll down, the address bar starts to move to the top, out of the screen, and the UIWebView doesn't scroll. Only when the address bar disappears completely, it starts to scroll. I would like to have this effect in my app as well. What's the best way to implement this? Thanks The only way to implement this requires iOS 5. In iOS 5, UIWebView has an UIScrollView subview. And use the following code: Set a area for the address bar: [[myWebView scrollView] setContentInset:UIEdgeInsetsMake(64, 0, 0,

I'm modally presenting a UIViewController with a UIWebView as its view. How do I dismiss the UIWebView when the user hits a cancel button on it? One idea I have is to have the cancel button link to http://cancel and then check in - (void)webViewDidStartLoad:(UIWebView *)webView If webView.request.URL.host isEqualToString:@"cancel" , then dismiss the view controller. Does the host have to have a dot in it, e.g., "cancel.com"? Rob Napier You're on the right path, but you're approach is slightly off. You don't need or want this to be an HTTP URL. Make your URL cancel: . <a href="cancel:">Thing to

When user tap on a universal link in WKWebView , the corresponding app will be opened (if installed). This is described in Apple Search Programming Guide If you instantiate a SFSafariViewController, WKWebView, or UIWebView object to handle a universal link, iOS opens your website in Safari instead of opening your app. However, if the user taps a universal link from within an embedded SFSafariViewController, WKWebView, or UIWebView object, iOS opens your app. In my app, I have a WKWebView , but I don't want the user to go out of my app. I want to handle the link within my WKWebView . How do I

All UIWebViews share a single web thread. When one of them is init -ed, removed from superview etc., they will attempt to lock the web thread from the main thread in a blocking fashion, thus temporarily freezing the run loop of the main thread. If the web thread is busy, e.g. while doing a long synchronous XMLHttpRequest , this may block the main thread for a long time. Is there a way to avoid this? If I could modify UIWebView, I'd just make the lock attempt non-blocking, but obviously that's not the case, so I'm looking for other clever ideas. The long and short of it is: avoid doing anything

I am using iPhone simulator to run a UIWebview, and Safari browser (on my mac) in order to debug the js / html / css code (via "develop" menu -> iPhone Simulator -> choosing my webview). Yestarday, the iPhone-simulator option disappeared from my "develop" menu: (as you can see, the "iphone-simulator" is missing here (it is opened in the background and working...) Any idea? Edit: I am using iOS 7 iPhone simulator + Safari 7 Edit 2: Just tried opening a website on iphone-simulator's Safari browser (in addition to the UIWebview). No luck here as well... I had exactly the same problem and I could

I want to integrate a full HTML framework (ie HTML/CSS/JavaScript) inside an iOS app and make the UIWebView in charge of running the HTML content being able to communicate with the rest of the native Objective-C source code. Direction 1: from Objective-C to HTML inside a UIWebView The way to make the rest of the source send messages to the HTML content is pretty straightforward: i can just call stringByEvaluatingJavaScriptFromString: on the Objective-C side and implement JavaScript methods the right way. Direction 2: from HTML inside a UIWebView to Objective-C This is the way I can't really

In the [webView:shouldStartLoadWithRequest:navigationType:] event, how can you tell the difference between an iframe that's loading content vs. the entire page loading content? It seems like the both call this same event with the same arguments, the only difference being the URL that's going to be loaded, so there is no way to tell the difference between the two. I've thought of a few ways to tell the difference though: Parse the source code of the page and store a list of all the iframe src attributes, assume that if the url loading is one of those in my list it's an iframe. Of course this

I've tried disabling it by inserting: <meta name="viewport" content="width=320" /> into my HTML string, and a dozen variations of the above in the vain hope that I just screwed up the tag syntax... but nothing seems to stop UIWebView from scrolling horizontally. And yet there are apps that manage to do this (like MobileRSS), and presumably, since they haven't gotten rejected, they're not using private APIs. My version, a common solution: - (void)webViewDidFinishLoad:(UIWebView *)webView { [webView.scrollView setContentSize: CGSizeMake(webView.frame.size.width, webView.scrollView.contentSize
