iPhone 6S plus和iPhone 7 plus中的启动图像问题

Question

我对Xcode很陌生。 我的应用启动屏幕上有某些图像。 我已使用拖放将其添加到图标（Images.xassets-> LaunchImage）。

它们都可以在除iPhone 6s plus和iPhone 7 plus之外的所有设备上正常工作。

我的contents.json文件看起来像这样

{

 "images" : [
{
  "orientation" : "portrait",
  "idiom" : "iphone",
  "extent" : "full-screen",

我正在使用Xcode 8，部署目标是iOS 10.0

任何帮助，将不胜感激

改变你的

{
  "extent" : "full-screen",
  "idiom" : "iphone",
  "subtype" : "736h",
  "filename" : "iOS_portrait_1080x1920.png",
  "minimum-system-version" : "8.0",
  "orientation" : "portrait",
  "scale" : "3x"
},

至

{
  "extent" : "full-screen",
  "idiom" : "iphone",
  "subtype" : "736h",
  "filename" : "iOS_portrait_1242x2208.png",
  "minimum-system-version" : "8.0",
  "orientation" : "portrait",
  "scale" : "3x"
},

并确保您的图片iOS_portrait_1242x2208.png分辨率确实为1242x2208 。
