preload

问题 Just migrated an app over to WKWebView and was wondering if there is any possible way to 'preload' multiple URLs, but only display one at a time? I have a list of 5 URLs. I already know that I will be shown at some point in time, and I want to speed up the experience by pre-loading these for use in a single WKWebView . 回答1: I ended up just using NSURLCache and preloading all URLs using NSURLRequest and NSURLConnection. Then whenever I load a url into WKWebView it uses the cached requests per

问题 Currently I'm writing a React App and struggling with a simple reading from a SQlite database. Edit because of unclear question : ***The goal is to read from the database without any backend, because it needs to read from the database even when it is offline. ***I'm aiming for a ONE TIME file conversion, then just pouchdb queries offline. But I don't want to do it manually because there are around 6k+ registries. ***Or SQL queries from the browser without any APIs, but I need to support

问题 I'm currently in the middle of trying to figure out how I can load / preload a large number of content on to a long page website. The solution I thought of, is to load content, after a previous part has loaded. THe HTML setup looks like this: <div class="panel">Panel 1</div> <div class="panel">Panel 2</div> <div class="panel">Panel 3</div> <div class="panel">Panel 4</div> Is there a way to load Panel 1, then once that has loaded, load Panel 2 and so on... With most solutions I've looked at,

问题 I'm trying out rel=preload for the first time, using it for a couple of stylesheets. Here is the code in question: <link rel="preload" href="css/styles.css" as="style"> <link rel="preload" href="//allyoucan.cloud/cdn/icofont/1.0.0beta/css/icofont.css" crossorigin="anonymous" as="style"> I'm testing in Chrome 61, and I can see that the stylesheets are downloaded as expected, however they're never actually applied, and I get the message on the console saying that a preloaded resource isn't

问题 Problem: An XML configuration file needs to be loaded at runtime and be ready when the application's createChildren() gets called. At the latest, because configuration values are needed to properly initialize child components. Preferably, I would like the configuration loading be complete before the application even gets created. In short, I want to do this: load configuration, then initialize the application using the loaded configuration. I created a custom preloader to help solve this. But

问题 I am trying to preload images, the following code works: $(document).ready(function(){ $(".member-photos img").each(function(){ var id = $(this).attr("data-id"); var file = $(this).attr("data-file"); var img = new Image(); img.src = "/user-data/images/image.php?id="+id+"&file="+file+"&width=600&crop=false"; }); }); But the issue I would like to solve, is that Chrome displays the spinning "Loading" icon in the tab. Is there a way I can do this so it doesn't continuously spin until the images

问题 Folks, I have designed an Adobe AIR application. I want to show some preloader on it, before it opens up. Can anyone guide me with tutorials on preloader aimed for AIR specifically or any already built in ones? Thanks 回答1: With AIR I can think of a couple of ways to achieve that: 1. with native windows Set the 'visible' attribute of your main WindowedApplication to 'false'. On 'creationComplete' event spawn a new Window that contains your splash screen. Perform the necessary logic before

问题 I have a WCF application hosted in Windows Azure. It has IIS v8.0 I have used IProcessHostPreloadClient's Preload() method for application warmup Now, I have two issues here: 1) whenever my application pool recycles, the Preload() function is called twice. I have some static variables being initialized in the preload() method which will persist in my worker process (w3wp.exe) . What I have seen is interesting: My current worker process ID is ( w3wp.exe 1234 ,say) when recycled, preload is

问题 When you preload textures using the spritekit preloadTextures function, it loads all the textures in the provided array into the memory at once. If you don't have the ability to split up your levels in your game with 'loading screens' but do have separate levels with different image files than each other, how can you keep from storing all the images in memory at once without sacrificing frame rate when spritekit loads the images when it needs to? 回答1: You could create a singleton class with
