问题描述
我正在使用UIImagePickerController
捕捉图像并将其上传到服务器.
I'm using UIImagePickerController
to snap an image and uploading it to server.
在前置摄像头中拍摄照片时,高度/宽度在某处相反.
When taking a photo in the front camera, the height/width get reversed somewhere.
稍后可以正确显示图像,但是高度和宽度却颠倒了(我将它们用于UIImageView自动布局约束)
The image is displayed correctly later, but height and width are reversed (and I'm using them for the UIImageView autolayout constraint)
问题是-在查看前后摄像机图像的UIImagePickerControllerMediaMetadata
时-EXIF和其余元数据相同(分辨率较小,但高宽比相同)
The thing is - that when looking at UIImagePickerControllerMediaMetadata
of front and back camera images - the EXIF and the rest of the metadata is the same (resolution is smaller but the height/width ratio is the same)
任何想法有什么区别?
推荐答案
Apple图像始终横向留有EXIF,并且在EXIF中指定了方向.
Apple images are always landscape left with EXIF and the orientation is specified in the EXIF.
