【问题描述】：
大约一年前我编写了代码，将照片或图片加载到网络。但是现在这段代码不起作用。我认为现在我使用的是 IOS 10。
在日志中：
[通用] 创建未知类型的图像格式是错误的
记者[34067:1053969] 回应{ 代码 = 5; msg = "文件为空"; }
请帮帮我，怎么了？

【问题讨论】：
-
从选择器视图中粉刷照片或上传照片不起作用？？
-
@CodeChanger 没有从选择器视图中粉刷照片。
-
@МарияТимофеева 你检查过这个stackoverflow.com/questions/38236723/…
-
您是否在实际获得此日志的位置调试代码？在 uploadPhoto 方法中？
-
@NiravD 是的，我检查了这个，但我们的问题并不相等。
