后面发现是 Cocos 引擎在 iOS 原生上的一个适配问题—— copyTexImagesToTexture 函数无法识别纹理数据类型，导致所有图片上传 GPU 失败。 copyTexImagesToTexture 函数只处理了两种类型：
-
HTMLCanvasElement→ 取texImage._data.data -
HTMLImageElement→ 取texImage._data
但 iOS 原生下， ImageAsset.data 返回的是 第三种格式 （ _nativeData 对象，不是 HTMLImageElement 也不是 HTMLCanvasElement），所以直接走到了 else 分支报错返回 → 所有图片上传 GPU 失败 → 按钮图片全空 。
代码： else if (texImage._data) {
images.push(texImage._data);
} else if (texImage.data && texImage.data._data) {
In some cases, the ImageAsset object is passed, and the data attribute is the _nativeData
images.push(texImage.data._data);
}
我目前是直接修改的是构建之后的这个文件：build/ios/data/jsb-adapter/engine-adapter.js。
估计还要修改引擎里面的对应的这个JS文件：/Applications/Cocos/Creator/3.8.7/CocosCreator.app/Contents/Resources/resources/3d/engine/bin/adapter/native/engine-adapter.js
官方后续是否可以修复这个问题呢？
