Comment rendre l'image toujours correcte?

Question

Après avoir pris une photo à partir de la caméra dans les modes landscapeLeft et LandscapeRight, l'image est enregistrée en mode paysage. L'image du résultat est jointe.

Après mon code et toutes les choses que j'essayé:

J'utilise PHPhotoLibrary pour enregistrer l'image dans l'album personnalisé.

// Take Image Button Method 
- (void)snapButtonPressed:(UIButton *)button 
    { 
    [self.camera capture:^(LLSimpleCamera *camera, UIImage *image,   NSDictionary *metadata, NSError *error) 
     { 
     if(!error) 
      { 

     NSString * info = [NSString stringWithFormat:@"Size: %@ - Orientation: %ld", NSStringFromCGSize(image.size), (long)image.imageOrientation]; 
     NSLog(@"IMAGE Meta Data:%@",info); 

     [CustomAlbum addNewAssetWithImage:image toAlbum:[CustomAlbum getMyAlbumWithName:CSAlbum] onSuccess:^(NSString *ImageId) 
     { 
      NSLog(@"IMAGE ID:%@",ImageId); 
      recentImg = ImageId; 
     } 
      onError:^(NSError *error) 
     { 
      NSLog(@"probelm in saving image"); 
     }]; 
    } 
    else 
    { 
     NSLog(@"An error has occured: %@", error); 
    } 
} 
     exactSeenImage:YES]; 
}

J'utiliser cette méthode pour mettre en œuvre la rotation de l'image fixe, tout en capturer l'image de la caméra. Je pense que c'est utile pour vous.

- (UIImage *) fixrotation:(UIImage *)image { 


if (image.imageOrientation == UIImageOrientationUp) return image; 
CGAffineTransform transform = CGAffineTransformIdentity; 

switch (image.imageOrientation) { 
    case UIImageOrientationDown: 
    case UIImageOrientationDownMirrored: 
     transform = CGAffineTransformTranslate(transform, image.size.width, image.size.height); 
     transform = CGAffineTransformRotate(transform, M_PI); 
     break; 

    case UIImageOrientationLeft: 
    case UIImageOrientationLeftMirrored: 
     transform = CGAffineTransformTranslate(transform, image.size.width, 0); 
     transform = CGAffineTransformRotate(transform, M_PI_2); 
     break; 

    case UIImageOrientationRight: 
    case UIImageOrientationRightMirrored: 
     transform = CGAffineTransformTranslate(transform, 0, image.size.height); 
     transform = CGAffineTransformRotate(transform, -M_PI_2); 
     break; 
    case UIImageOrientationUp: 
    case UIImageOrientationUpMirrored: 
     break; 
} 

switch (image.imageOrientation) { 
    case UIImageOrientationUpMirrored: 
    case UIImageOrientationDownMirrored: 
     transform = CGAffineTransformTranslate(transform, image.size.width, 0); 
     transform = CGAffineTransformScale(transform, -1, 1); 
     break; 

    case UIImageOrientationLeftMirrored: 
    case UIImageOrientationRightMirrored: 
     transform = CGAffineTransformTranslate(transform, image.size.height, 0); 
     transform = CGAffineTransformScale(transform, -1, 1); 
     break; 
    case UIImageOrientationUp: 
    case UIImageOrientationDown: 
    case UIImageOrientationLeft: 
    case UIImageOrientationRight: 
     break; 
} 

// Now we draw the underlying CGImage into a new context, applying the transform 
// calculated above. 
CGContextRef ctx = CGBitmapContextCreate(NULL, image.size.width, image.size.height, 
             CGImageGetBitsPerComponent(image.CGImage), 0, 
             CGImageGetColorSpace(image.CGImage), 
             CGImageGetBitmapInfo(image.CGImage)); 
CGContextConcatCTM(ctx, transform); 
switch (image.imageOrientation) { 
    case UIImageOrientationLeft: 
    case UIImageOrientationLeftMirrored: 
    case UIImageOrientationRight: 
    case UIImageOrientationRightMirrored: 
     // Grr... 
     CGContextDrawImage(ctx, CGRectMake(0,0,image.size.height,image.size.width), image.CGImage); 
     break; 

    default: 
     CGContextDrawImage(ctx, CGRectMake(0,0,image.size.width,image.size.height), image.CGImage); 
     break; 
} 

// And now we just create a new UIImage from the drawing context 
CGImageRef cgimg = CGBitmapContextCreateImage(ctx); 
UIImage *img = [UIImage imageWithCGImage:cgimg]; 
CGContextRelease(ctx); 
CGImageRelease(cgimg); 
return img; 

}
