问题 Is there a way to zoom out or reset a UiWebView programmatically ? if yes how ? 回答1: i think you should be able to manipulate the viewport using the safari meta tags https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html#//apple_ref/doc/uid/TP40008193-SW6 For example, to set the viewport width to the width of the device, add this to your HTML file: <meta name = "viewport" content = "width = device-width"> To set the initial

问题 I'm developing a book reader for iOS using a UIWebView . At the moment I'm working with some basic HTML files but will eventually work with ePubs. I am looking for a suitable way of styling ranges of text.

问题 This is similar to this much older issue: HTML file input with multi selection in UIWebView not working for videos This is NOT a duplicate of this: iOS update to 10.3.1 breaks HTML input element I have tested this on my app that was working, on versions going back 45 days, it seems iOS 10.3.1 changed the file input and now there is the multiple video selection, without the "compressing" stage that occurred after selection and before switching out of the interface. Tested on iphone 6S. When

The following code disables both scrolling directions, but I want to only disable vertical: myWebView.scrollView.scrollEnabled = NO; How do I solve this problem? 回答1: Enable Horizontal scrolling and disable Vertical scrolling: myWebView.scrollView.delegate = self; [myWebView.scrollView setShowsVerticalScrollIndicator:NO];

问题 I have a strange problem with UIWebView's loadHTMLString, where it would only display a blank view when I called loadHTMLString with my content HTML string. It does not matter what the content of the htmlstring is, it simply does nothing. The strange thing is that it used to work a few weeks ago, when I tested it on the simulator and device. My code is below: NSMutableString *sHtmlBuf = [NSMutableString stringWithString:@"<body style=\"background-color: #000000; color: #FFFFFF; font-family:

But is there any native API available on IPhone(which the native iphone map application uses)? 回答1: Look at the simple framework from CloudMade: http://developers.cloudmade.com/projects/show/iphone-api I use it in a simple app that I created to locate your position.
