问题 I use the following HTML template with an to hand to a UIWebView. I understand that this is the supported way to play youtube videos. <html> <body> <!-- 1. The <iframe> (and video player) will replace this <div> tag. --> <div id="player"></div> <script> // 2. This code loads the IFrame Player API code asynchronously. var tag = document.createElement('script'); tag.src = "http://www.youtube.com/player_api"; var firstScriptTag = document.getElementsByTagName('script')[0]; firstScriptTag

Why would a link in a UIWebView leave a gray box behind?

由 喜夏-厌秋 提交于 2019-12-06 07:31:43
I have a UIWebview that I am loading with custom HTML using loadHtmlString. My HTML has a link that I intercept when tapped so that I can take control and reload the UIWebview with a different HTML string. The code works, but the area where the link text was located is replaced with a gray rectangle that is visible when the new string is loaded. What could be going on here? How can I get rid of this behavior? //Scott Here it is...need to add this style statement to the link reference: <a href=http://yourlink.com/ style = "-webkit-tap-highlight-color:rgba(0,0,0,0);"> Setting the alpha value

How to find the responder that is returning YES to canPerformAction:withSender:

由 蹲街弑〆低调 提交于 2019-12-06 07:23:27
I need to disable the Define menu item from the edit menu on a UIWebView. This is supposed to be done by implementing canPerformAction:withSender: and returning NO for the items to disable. Even though these are private items it seems like I should be able to return YES for the items I want to keep and NO for everything else (as in this question ). However this is not working. The documentation says that If no responder in the responder chain returns YES, the menu command is disabled. Note that if your class returns NO for a command, another responder further up the responder chain may still

Getting the position of an HTML element in UIWebView

由 一世执手 提交于 2019-12-06 07:22:41
I have UIWebView loaded with an HTML file. I want to know the position (means x and y cordinates) of an HTML element on the screen when the webview is loaded. Thanks in advance William Niu You may need to a combination of JavaScript and Objective-C to achieve this. You need a JavaScript function to pass back the screen position of certain element, and then translate that position to the screen on the iPhone. - (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script One way is to write a JavaScript that takes an element ID and returns its position and the screen resolution. Then

Detect video start playing in WKWebView

由 Deadly 提交于 2019-12-06 07:06:56
问题 I'm using WKWebView for loading an youtube page. I need to detect the video starts playing in the webview in inline mode and in the full screen mode. I tried MPMoviePlayerController Notifiers but they are not calling. But the same is working in UIWebView. So my question is, Is there any difference in the video playing mechanism used in UIWebView and WKWebView ? Why MPMoviePlayerController Notifiers are not calling in WKWebView ? Is there any method to detect the video play in WKWebView ? Or

UIWebView into a UITableViewCell with dynamic size

由 社会主义新天地 提交于 2019-12-06 06:58:37
问题 I have UIWebView objects into multiples UITableViewCell . Each webView has a different size. Originally, all cells are the same height.

However, webViewDidFinishLoad is only called after the resize method,

问题 I am writing an app in order to automate the process of connecting an Apple mobile device to a wifi network and downloading configuration profiles to the device.

I am already using Apple80211 private framework to connect to a wifi network as well as UIWebView in place of a browser in order to navigate to a specific
