1.iTunes Store Operation Failed
Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 7.0.
这个错误表示，系统找不到所需要的120*120分辨率的图片。查看对应120*120分辨率的图片，实际分辨率是不是120*120，或者格式是不是png。
2.点击Upload to App Store 提示no accounts with itunes connect access 错误
重启Xcode重新打包后正常
