如何在代码中“照亮" iPhone上的png? [英] How can I ‘shine’ a png on the iPhone in code?
问题描述
如何复制应用启动器在正方形.png上使用的效果，以向用户显示其图标作为应用徽章的外观.
How do I replicate the effect that the app launcher uses on a square .png to show my users what their icon will look like as an app badge.
注意-我想在iPhone上而不是在计算机上的photoshop中使用此代码.
NB - I want to do this in code on the iPhone, not in photoshop on my computer.
谢谢！
试图在这里弄清楚.我该如何使用 code ！ 我曾尝试创建一个叠加层，但是闪耀的苹果实际上确实使顶部变亮，因此仅在顶部放置png不会产生相同的效果.
edit: trying to be really clear here. How do I do this with code! I have tried creating an overlay, but the shine apple does actually brightens the top, so just putting a png over the top will not give the same effect.
大概是应用启动器会应用一些CA效果-有人知道如何复制它们吗?
Presumably the app launcher applies some CA effects - does anyone know how to duplicate them???
推荐答案
另一种更简单的方法是将您的图标另存为57px x 57px PNG，称为"icon.png"，而没有任何闪光效果，然后将其通过FTP传输到根文件夹Web服务器，然后在其中创建一个名为icon_test.html的文件，其中包含以下代码:
Another more simple approach is to save your icon as a 57px x 57px PNG called "icon.png" without any shine effects, then FTP it to the root folder of a web server and create a file there called icon_test.html containing the following code:
<html>
<head>
<link rel="apple-touch-icon" href="/icon.png"/>
<title>The App Name</title>
</head>
<body>
iPhone test page
</body>
</html>
然后只需在iPhone上的移动Safari中浏览到icon_test.html文件，点击工具栏中的"+"按钮将页面另存为书签，点击添加到主屏幕"，然后点击右上角.然后，您会看到您的图标出现在主屏幕上，并带有Apple的光泽覆盖.
Then just browse to the icon_test.html file in mobile Safari on your iPhone, tap the "+" button in the toolbar to save the page as a bookmark, tap "Add to Home Screen", and tap "Add" in the top right. You'll then see your icon appear on the home screen, complete with Apple's shine overlay.
