iOS JPEG图像旋转90度 [英] iOS JPEG images rotated 90 degrees

问题描述

我正在使用选择器视图从相册中选择图像。我使用上面的代码：

I am using picker view to select image from photo album. I use above code:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{

updateImage = [info objectForKey:UIImagePickerControllerOriginalImage];

[self.view addSubview:[MUtility sharedObject].loadingView ];

[self dismissViewControllerAnimated:YES completion:nil];

}

之后我上传到服务器和我使用此代码

After that i upload to server and i use this code

NSData *imageData = UIImageJPEGRepresentation(updateImage, 0.1);

但此图像旋转了90度。只有肖像照片旋转。
我该如何解决这个问题？

But this image rotated 90 degrees. Only portrait photo rotated. How can i solve this problem ?
