问题 In my app there's a UIWebView . The loaded webpage in it has some images, and I would like to use these images in somewhere else (e.g. display them in UIImageView ) So is it possible to get the loaded images directly from UIWebView without downloading them again? What I am doing now is get the URLs to the images from the html file and download them, but this is too time consuming. 回答1: I've figured this out: the key is to extract the images from the NSURLCache . However, since iOS 8, it seems

Or. take some other action like change a navigationBar item. 回答1: Yes you can do this. Implement – webView:shouldStartLoadWithRequest:navigationType: This delegate . This method gets called whenever your webview is about to make a request. So now when someone clicks a button or hyperlink on your webpage, you

问题 I am developing a video application which contains a lot of video from different sources. One of the options in the application has to be to play videos through airplay on a TV. For displaying YouTube video in my application I am using YTPlayerView, which is an objective-C helper for the YouTube API.

问题 I'd like to use WKWebView instead of a UIWebView to display data on iOS. However, it seems that loadData:MIMEType:textEncodingName:baseURL: was removed in WKWebView.

问题 I have embedded a Youtube video in my iOS 8.3 app using youtube's standard embed url (sample) which is working as expected but looking pretty weird. That white gap (blue zone on the view tree inspector) should not be there. I can confirm it's not a CSS issue as the inspector shows it is effectively occupying 100% width and height of the uiWebView component. I have setup constraints to the left, top and right borders to equate the window/layout guides so that's not the problem either. It seems

问题 I am using this library https://github.com/ninjaprox/NVActivityIndicatorView for showing the loading indicator. By default it blocks the entire view controller but how can I show the activity indicator only for the particular view. For example if a view controller contains a webview and some other view, the activity indicator should be only for the webview and I should be able interact with the other view. class FaqViewController: UIViewController, UIWebViewDelegate { @IBOutlet var faqWebView
