Question

I was wondering if creating a sprite for an HTML5 app, and wrapping it with phonegap for iPhone and Android, would increase performance at all. Because the app is offline, so it is only making a call for the image out of local storage.

Answer 1

In theory, no. However, at least on iOS, images aren t pre-loaded for each page load and you sometimes may see a flash as the image is loaded into the page. So a sprite is one way to handle that. Another way is to use some JS to load all of your app s images in the background on the home page. It takes a bit longer for the app to load, but then everything is cached and ready to go.

但是,如果做间谍活动是方便的,则是维修。只有保存数十份个人形象档案,才能使少数图像 sp缩。
