LaunchImage无法正确处理某些iPad

Question

我正在为我的应用程序的LaunchImage使用images.xcassets，某些类型的iPad正在启动时显示iPhone图像或AppIcon图像，而不是指定的iPad图像。

以下是我的应用图标和启动图像设置的屏幕截图

以下是我的xcassets文件的Contents.json的代码：

{
  "images" : [
    {
      "extent" : "full-screen",
      "idiom" : "iphone",
      "subtype" : "736h",
      "filename" : "ios_launch 7 plus.png",
      "minimum-system-version" : "8.0",
      "orientation" : "portrait",
      "scale" : "3x"
    },
    {
      "extent" : "full-screen",
      "idiom" : "iphone",
      "subtype" : "667h",
      "filename" : "ios_launch 7@2x.png",
      "minimum-system-version" : "8.0",
      "orientation" : "portrait",
      "scale" : "2x"
    },
    {
      "orientation" : "portrait",
      "idiom" : "iphone",
      "filename" : "ios_launch se-1.png",
      "extent" : "full-screen",
      "minimum-system-version" : "7.0",
      "scale" : "2x"
    },
    {
      "extent" : "full-screen",
      "idiom" : "iphone",
      "subtype" : "retina4",
      "filename" : "ios_launch se.png",
      "minimum-system-version" : "7.0",
      "orientation" : "portrait",
      "scale" : "2x"
    },
    {
      "orientation" : "portrait",
      "idiom" : "ipad",
      "filename" : "ios_launch ipad.png",
      "extent" : "full-screen",
      "minimum-system-version" : "7.0",
      "scale" : "1x"
    },
    {
      "orientation" : "portrait",
      "idiom" : "ipad",
      "filename" : "ios_launch ipad pro.png",
      "extent" : "full-screen",
      "minimum-system-version" : "7.0",
      "scale" : "2x"
    }
  ],
  "info" : {
    "version" : 1,
    "author" : "xcode"
  }
}

我不确定为什么会这样。这不会发生在iPad Air上。我能找到很少的文档可以提供帮助。感谢我能得到的任何帮助。

使用启动故事板并设置相应的图像并将图像宽高比从中心对齐。
