问题 I have a UIWebView as the root view of a UINavigationController . When a webpage finishes to load, I hide the navigation bar, and I'm looking for a way to show it back. Right now, I'm trying to do that when the user taps the status bar (this approach looks to me more complicated than what I want).

问题 I was wondering if it's possible to create a HTML div container with some CSS magic that shows a horizontal scrollbar like the one with the screenshots on the iTunes preview on the web.

问题 I am developing an Objective C application that loads a large HTML document in to a UIWebView as the user scrolls through it. This is because the document is 20Mb and tends to crash the webview if loaded all at once. The idea is that the document is split in to chunks of HTML and as the user scrolls through it new elements are added to the document and old elements are removed. Currently I am working on getting the Objective C application to pass data to a javascript function within the

UIWebView and CSS fixed position

由 大城市里の小女人 提交于 2019-12-08 04:41:27
I have a UIWebView that uses a fixed position header. When the ViewController that contains the UIWebView is the initial view, there is no problem with the fixed position divs. When I display that same ViewController through a Modal segue, that's when the problem occurs. The first time I scroll on the page, the divs move and scroll with the page, but once I let go of scrolling for the first time, the div returns to its fixed position and the error never happens again. Any ideas? I've seen iScroll , it doesn't quite work like I want the page too, and I think there's an easier way, since I only

WKWebView gives SecurityError when bundling html and javascript with app

由 爱⌒轻易说出口 提交于 2019-12-08 04:03:00
问题 We are trying to migrate a hybrid app from UIWebView (iOS < 8) to WKWebView (iOS 8), but we are getting SecurityErrors when trying to store stuff using the DOM WebDatabase API (i.e. 'web sql databases'). The following throws an error if the index.html has been loaded from a bundled file with the app // throws SecurityError: DOM Exception 18 var db = openDatabase('mydb', '1.0', 'key value store', 1); The same code works fine with UIWebView. I can fallback to using Local Storage for some reason
