一.ERROR ITMS-90096

这是最常见的问题，据说是苹果的bug。明明LaunchImage里有iphone5的启动图片，但还是报错。可以按以下方法解决
1.添加一张启动图片到项目的根目录，尺寸为320*568，格式为png，命名为Default-568.png。

2.使用文本编辑打开info.plist，添加下面代码

<key>UILaunchImages</key> 
<array> 
<dict> 
<key>UILaunchImageName</key> 
<string>Default-568</string> 
<key>UILaunchImageSize</key> 
<string>{320, 568}</string> 
</dict> 
</array>

在xcode打开info.plist，如图

添加成功
3.shift+command+K clean一下
4.command+B build一下 如果xcode没有报错就可以重新上传了。我之前是图片有问题报错了，上传还是失败，后来重新做了张图片，就成功了

二.
ERROR ITMS-90705: “Launch storyboard not found. Make sure you specify the launch storyboard filename without a filename extension for the key UILaunchStoryboardName in the Info.plist.”
检查info.plist里的LaunchScreen
UILaunchStoryboardName
LaunchScreen
检查LaunchScreen.storyboard是否存在
也可以使用LaunchImage，将设置里的LaunchScreen File清空

缺少app icon，在image.xcassets里的添加即可，所有的图标都要按照尺寸添加
