This problem has nothing to do with Qiniu. I suggest you take a look at the imageOrientation property of UIImage.
After adding imageMogr/auto-orient, the vertical image is returned, which means it is a normal result. Are there any problems that need to be solved? If you want to upload the image taken vertically and upload it vertically, and return the vertical image without auto-orient, you can correct the orientation of the image before uploading the image. There are many examples here. Code: http://stackoverflow.com/questions/8915630/ios-uiimageview-how-to-handle-uiimage-image-orientation
