由 ぐ巨炮叔叔 提交于 2019-11-28 23:15:25
问题 I'm stuck on getting some pretty basic JS to run in my UIWebView. In the web view's delegate, I have : - (void)webViewDidFinishLoad:(UIWebView *)wView { NSString *someHTML = [wView stringByEvaluatingJavaScriptFromString:@"document.getElementsByClassName('box')[0]"]; NSString *allHTML = [wView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"]; NSLog(@"someHTML: %@", someHTML); NSLog(@"allHTML: %@", allHTML); } but when the method is invoked, someHTML is nil while allHTML

How to get HTTP headers

问题 How do you retrieve all HTTP headers from a NSURLRequest in Objective-C? 回答1: This falls under the easy, but not obvious class of iPhone programming problems. Worthy of a quick post: The headers for an HTTP connection are included in the NSHTTPURLResponse class. If you have an NSHTTPURLResponse variable you can easily get the headers out as a NSDictionary by sending the allHeaderFields message. For synchronous requests — not recommended, because they block — it’s easy to populate an

I want to disable long-touch from the application. I have no control on the HTML that I am loading on my WebView.

How can I get a UIWebView to focus on a form input and bring up the keyboard?

I've created a UIWebView for logging into Facebook's Graph API OAuth interface. This works great, but I have to tap the first input field in order for the keyboard to pop up. Ideally, the keyboard would appear as soon as the form appears. So I've been trying to figure out how to make the first form field get the focus from the webViewDidFinishLoad: UIWebViewDelegate method, like so: - (void)webViewDidFinishLoad:(UIWebView *)wv { [webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByName('email')[0].focus();"]; } Alas, this does not work. Curiously, when I run that JavaScript

How to handle app URLs in a UIWebView?

由 社会主义新天地 提交于 2019-11-27 16:56:58
I recently found that my UIWebView was choking on ITMS links. Specifically, from the UIWebView in my app, if I navigate to a site such as this one and click the "Available on the App Store" link, UIWebView would error out with "Error Domain=WebKitErrorDomain Code=101 The URL can't be shown." After a bit of Googling, I realized that I needed to catch requests for app links and have iOS handle them. I started out by looking to see if the scheme starts with "itms" in -webView:shouldStartLoadWithRequest:navigationType: , but realized that there might be other kinds of app links that the system can

In my application, I have a UIWebview that loads linkedin auth page for login. When user logs in, cookies saves into the application. My app has a logout button that is not related to linkedin login.
