didFinishPickingMediaWithInfo方向問題

Question

我試圖管理圖像旋轉imagePickerController:didFinishPickingMediaWithInfo，但經過多次嘗試，我沒有找到任何解決方案。我最後的嘗試是：

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

     // load the storyboard by name 
     UIStoryboard *storyboard = [UIStoryboard storyboardWithName:[ApplicationSupport getStoryBoardName] bundle:nil]; 
     UploadViewController *uploadView = [storyboard instantiateViewControllerWithIdentifier:@"ViewUploadFile"]; 

     UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage]; 
     NSDictionary *metadataImage = [info valueForKey:UIImagePickerControllerMediaMetadata]; 

     uploadView.imageToUpload = image; 

     if([[metadataImage objectForKey:@"Orientation"] intValue] == 3) { 
      UIImage *imageRotated = [UIImage imageWithCGImage:[image CGImage] scale:[image scale] orientation:UIImageOrientationDown]; 
      uploadView.dataToUpload = UIImagePNGRepresentation(imageRotated); 
     } else { 
      uploadView.dataToUpload = UIImagePNGRepresentation(image); 
     } 

     // ETC... 
    } 

我不能和我不想使用JPEGRepresentation。當iPad處於特定位置時，我需要將照片旋轉180°。

任何想法？

Answer 1

看看這個：http://www.catamount.com/blog/1015/uiimage-extensions-for-cutting-scaling-and-rotating-uiimages/

只需撥打

UIImage *rotatedImage = [originalImage imageRotatedByDegrees:180.0];

Answer 2

UploadView.DataToUpload = [UIImage imageWithCGImage：[image CGImage] scale：1.0 orientation：UIImageOrientationDown];

180度旋轉。
