【中文标题】iPhone 6S plus 和 iPhone 7 plus 中的启动图像问题

【英文标题】：Issue with launch image in iPhone 6S plus and iPhone 7 plus

【发布时间】：2016-11-10 11:52:05

【问题描述】：

我对 Xcode 很陌生。我的应用程序启动屏幕有某些图像。我已经通过拖放将它们添加到图标（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 文件如下所示

我使用的是 Xcode 8，部署目标是 iOS 10.0

任何帮助将不胜感激

【问题讨论】：

我建议使用启动故事板。添加一个 UIImage 视图，将其约束到屏幕边缘并让 iOS 为您缩放图像

【参考方案1】：

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"
,

到

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

并确保您的图像 iOS_portrait_1242x2208.png 分辨率确实是 1242x2208。
