很长一段时间习惯了用企业级证书发布，最近的新项目使用Xcode 9.1发布到AppStore时遇到了一个小问题（emm..其实问题跟Xcode版本没关系，我也不知道为什么要声明这个233），如下：
ERROR ITMS-90096: "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."
字面意思来看，是果爹砍了iPhone4系列之后，仍旧需要开发者们适配iPhone5系列（os：如果库克不是为了卖SE他会保留5系手机？）
废话不多说了，其实这个问题只需要在Asset的LaunchImage的右侧勾选iOS7 and Later的portrait选项，那么LaunchImage就会多出两个需要插入启动图的位置（2x和Retina 4）
我这里只添加了Retina 4的尺寸图，也就是640x1136大小，clean一下重新打包即可
如下图所示
