ios - 在 xCode 6.4 中成功构建项目后，在 xCode 7 Beta 6 中构建项目时出错

Question

在我升级IDE之后，尽管没有改变任何其他东西，但输出了以下错误:

您的问题确实是由于 xCode 7 中的 xcassets 格式发生了变化。但是，通过删除 block ，您将丢失图像拉伸(stretch)行为设置。

相反，您可以通过将 "cap-insets" 更改为 "capInsets" 并将 "mode": "tile" 更改为 “模式”:“填充”

这是您案例的结果字符串:

{
  "images": [
    {
      "idiom": "universal",
      "filename": "login_show_button.png",
      "scale": "1x"
    },
    {
      "resizing": {
        "mode": "9-part",
        "center": {
          "mode": "tile",
          "width": 4,
          "height": 3
        },
        "cap-insets": {
          "bottom": 5,
          "top": 6,
          "right": 7,
          "left": 9
        }
      },
      "idiom": "universal",
      "filename": "login_show_button@2x.png",
      "scale": "2x"
    },
    {
      "idiom": "universal",
      "scale": "3x"
    }
  ],
  "info": {
    "version": 1,
    "author": "xcode"
  }
}
