##2.本插件优点:

Icon设计师只需要设计一份1024x1024图标,本插件会自动按App的要求生成各个标准尺寸图标.
可以同时导出辅助文件到App的开发环境当中直接编译.这也极大减轻开发者的工作量
也能按要求生成各大应用市场要求各种尺寸图标.

2. 2直接导入开发环境原理

如iOS 不仅生成图标,还会自动在AppIcon.appiconse 目录下生成相应的Content.json文件,在XCode的项目能直接打开.

如下是由本插件自动生成图标描述文件效果,可以看到所有要求到尺寸均可

而传统的方式,是Sketch设计师输出图标,然后开发者工程师在Xcode 逐一拖入图标asset生成器中,而且如果拖入尺寸与对应机型要求图标尺寸不一致还是收到编译警告,部分情况下还会造成编译错误.整个过程相当繁琐.

Android 中会自动生成相应drawable目录,并将同名图标按要求放入.无论用Android Studio/Eclipse 均可直接编译.

###2.3 生成应用市场发布要求各种图标

各个应用市场对于尺寸要求不一样,本插件同样可以直接生成. 本插件能生成 Google play ,iTune,QQ,小米市场等各种尺寸
