iOS LaunchImage尺寸详细对照表（. xcasset

Q：用.xcassets的LaunchImage 还是用LaunchScreen.storyboard？

A：原则：你开心就好！But，使用LaunchScreen.storyboard时，通过Today插件或者桌面3D-Touch，会使用到启动页。

LaunchImage（xcassets）尺寸对照表：

iOS 7.0 + iOS 8.0 and later  Protrait & Landscape

请选择上：iOS 7.0 and later

填坑记录：

情况：项目兼容的iOS版本9.0+，LaunchImage的“iOS 7.0 and later”就理所当然的未选择。

结果：Archive发布验证时报错：

"Your binary is not optimized for iPhone 5 - New iPhone apps and app updates submitted must support the 4-inch display on iPhone 5 and must include a launch image referenced in the Info.plist under UILaunchImages with a UILaunchImageSize value set to {320, 568}. Launch images must be PNG files and located at the top-level of your bundle, or provided within each .lproj folder if you localize your launch images. Learn more about iPhone 5 support and app launch images by reviewing the ‘iOS Human Interface Guidelines‘ at https://developer.apple.com/ios/human-interface-guidelines/graphics/launch-screen."

分析：虽然项目兼容iOS版本是9.0+，但是苹果还是要求开发者去兼顾适配iPhone5系列。你可以这么想，iPhone 4s 或 iPhone 5也是可以使用9.0系统的。

处理：LaunchImage的“iOS 7.0 and later”请勾上。
