<Error>: ImageIO: PNG invalid PNG file: extra chunks between iDOT and IDAT
提问by potato
Just got this funny looking error in my swift project debugger.
刚刚在我的 swift 项目调试器中遇到了这个看起来很有趣的错误。
There is probably an invalid name of an image somewhere, but I am not sure what extra chunks between iDOT and IDATmean.
某处可能有一个无效的图像名称，但我不确定是什么extra chunks between iDOT and IDAT意思。
Do you have any idea what causes it?
你知道是什么原因造成的吗？

This issue is completely random and happened to me too with a few images. Probably another Xcode bug.
这个问题是完全随机的，我也遇到了一些图像。可能是另一个 Xcode 错误。
- My image is called "[email protected]"
- I renamed it to "back2.png"
- Ran the project (the image will appear stretched)
- Changed it back to "[email protected]"
- Ran project
- FIXED?!
- 我的图像被称为“[email protected]”
- 我将它重命名为“back2.png”
- 运行项目（图像将出现拉伸）
- 把它改回“[email protected]”
- 冉项目
- 固定的？！
Good-luck hope it helps!
祝你好运希望它有帮助！

In XCode 8, I cleaned the project (Product->Clean). Then quit XCode. Open it again. Then it works. I haven't changed name of the image. I guess it is just because XCode has some problem. Nothing is wrong with your code.
在 XCode 8 中，我清理了项目（Product->Clean）。然后退出 XCode。再打开。然后它起作用了。我没有更改图像的名称。我想这只是因为 XCode 有一些问题。您的代码没有任何问题。

I just delete all images which have problem to appear and after load again the same images and work perfectly.
我只是删除所有出现问题的图像，然后再次加载相同的图像并完美运行。
