ios开发之 icon规范+启动图规范+启动页规范

作为一名开发人员,有时候碰上美工有事外出,那么偶尔就得顶下美工的岗位,切切图。今天就简单的说一下。

手机以（iPhone 4s-iPhone 6P）为主，若有新产品，会及时更新内容。

1、先说说AppIcon图标，除了要适配手机屏幕尺寸外，平板要兼顾，甚至搜索软件的时候，出现在列表页的图标，都是不同规范。

 

 

一般都会准备10套，别惊讶，就是这么多。

 

2、接下来是启动图。每个APP启动的时候，都会看到一张固定的预览图（这里指一般静态，不包含随时更新的动态效果），再进入首页。一般我是采用4套图片就可以了。

 

 

3、接下来就是欢迎页，首次使用APP，都会给用户带来几张可以左右滚动的产品介绍图。至于要多少张数量为最佳，没有严格规定，个人的建议是5张图片就可以了。不多说，上图。

 

以上三样规范，命名一般都是可以默认为文章说明的样式，也可以自定义。但是建议大伙还是按照前人的风格，不要乱起名字，避免到时候出现离奇BUG，就不好了。

App Icons on iPad and iPhone

Important: This is a preliminary document for an API or technology in development. Apple is supplying this information to help you plan for the adoption of the technologies and programming interfaces described herein for use on Apple-branded products. This information is subject to change, and software implemented according to this document should be tested with final operating system software and final documentation. Newer versions of this document may be provided with future betas of the API or technology.

 

Q:  How are the icon files in my application bundle used on iPad and iPhone?

A: Below are guidelines for handling icon files for iPhone-only apps, iPad-only apps, and universal apps.

If you don't provide artwork for one of the listed optional icons, the system will automatically scale one of your existing icon images to an appropriate size. It is strongly recommended that your application include artwork for all the icons listed, at the specific sizes needed.

Prior to iOS 3.2, icon images were required to follow a strict naming convention. These legacy names are still listed in the tables below along with example names for the more recent icons. Except for iTunesArtwork, icon images included in your app can have arbitrary names.

Note: iOS ignores the PPI (Pixels Per Inch) of icon images. You may author your icon images at any PPI but their width and height, as measured in pixels, must match the values in the tables below.

 

Important: iTunesArtwork icon images should be in png format, but name them without the .png extension.

 

Icons for iPhone-only Apps

iPhone-only applications use the following icons. Items marked with "Required" must be included.

Note: You should include images for the iPad-specific icons even if your app is not a universal app. If available, they will be used when the app is installed on an iPad.
