我有xamarin表单上的应用程序。我尝试在Apple Store中发布应用程序（使用Transporter应用程序）。我遇到此错误：

ERROR ITMS-90022: "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.

如果有4个文件丢失（“120x120”、“152x152”、“167x167”、“76x76”）。我尝试了不同的选项和不同的服务，这是我的最后一个（来自Contents.json）。

....
{
  "scale": "1x",
  "size": "76x76",
  "idiom": "ipad",
  "filename": "Icon76.png"
},
{
  "scale": "2x",
  "size": "76x76",
  "idiom": "ipad",
  "filename": "Icon152.png"
},
{
  "scale": "2x",
  "size": "83.5x83.5",
  "idiom": "ipad",
  "filename": "Icon167.png"
},

这是我的信息。plist：

这些文件是目前为什么我得到的错误？任何建议，我将不胜感激。已经花了很多时间。
