Fix image orientation + iphone

I am using the camera function in my application and save the images to the document directory after clicking on the photo. Whenever I use images, the orientation of those images changes. So for this I search on stackoverflow and get the solution from this link:

iOS UIImagePickerController - Result of image orientation after loading

But I can't figure out how to use the fix orientation method to get the original orientation of the image. If anyone knows about this please help me.

Thanks everyone.

Add this method somewhere. Then:

UIImage *origImage = <from somewhere>;
UIImage *fixed = [origImage  fixOrientation];


This is a category method, so you can add it to any implementation. It is generally good practice to create a separate file like UIImage+rotationFix.{m,h}

.

  • Add this category to your project

    UIImage + fixOrientation

    or you can create it manually using the links below.

    [1]: [code for UIImage + FixOrientation.h]

    https://github.com/j3r3miah/mapmatic-ios/blob/master/Mapmatic/UIImage+FixOrientation.h

    [2]: [code for UIImage + FixOrientation.m]

    https://github.com/j3r3miah/mapmatic-ios/blob/master/Mapmatic/UIImage+FixOrientation.m

    After creating this category, import it into your view controller,

    import "UIImage + fixOrientation.h"

    and implement this delegate UIImagePickerController

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

        UIImage *myimage = [info objectForKey: UIImagePickerControllerOriginalImage];
        myimage=myimage.fixOrientation;
}

This fixOrientation method would fix the image orientation in portrait mode.
