Getting rotated image form server when it is uploaded

Question

- (IBAction)grabImage{
    UIImagePickerController *ipc = [[UIImagePickerController alloc] init];
    ipc.delegate = self;
    ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:ipc animated:YES];
    [ipc release];

}

     turning the image into a NSData object
s    getting the image back out of the UIImageView
     setting the quality to 90
     */
    //MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    //hud.labelText = @"Uploading image ";

    //assume that the image is loaded in landscape mode from disk




    NSData *imageData = UIImageJPEGRepresentation(image.image, 0.09);

    // setting up the URL to post to
    NSString *urlString = NSLocalizedString(UploadText, @"");

    /*
     add some header info now
     we always need a boundary when we post a file
     also we need to set the content type

     You might want to generate a random boundary.. this is just the same

    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

    // Create a image file name

    // now lets make the connection to the web
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
    NSLog(@"%@",returnString);

    //[MBProgressHUD hideHUDForView:self.view animated:YES];


    label.hidden=YES;

Use this code https://gist.github.com/1064652 for fix image orientation before uploading it to the server.

UPD: Click to create new file, select Cocoa Touch, then Objective-C category. Then write FixOrientation in "Category" field, and UIImage in "Category on" field. Then click next and complete files creation. After that, insert method declaration

- (UIImage *)fixOrientation;

in UIImage+FixOrientation.h

and copy implementation from github to UIImage+FixOrientation.m file.

Next, add

#import "UIImage+FixOrientation.h"

to your class, were you work with image.

After that, replace string

NSData *imageData = UIImageJPEGRepresentation(image.image, 0.09);

to string:

NSData *imageData = UIImageJPEGRepresentation([image.image fixOrientation], 0.09);
