使用解析SDK保存图像

Question

拍摄图像：

我正在使用此问题中的代码获取图像：使用UIIImagePicker的CGAffineTransform缩放UIImage并保存到Parse SDK

将UIImage转换为NSData并保存

    _imageData = UIImageJPEGRepresentation(_image, .1);
    PFFile *imageFile = [PFFile fileWithName:@"image.png" data:_imageData];
    newMessage[@"image"] = imageFile;

问题：

当我重新下载数据时，UIImage看上去被压缩了。 当我查看数据库中的图像时，似乎高度和宽度是相反的。 不知道为什么会这样...

NSData *imageData = UIImageJPEGRepresentation(yourImage, 1.0);
PFFile *imageFile = [PFFile fileWithName:@"Image.jpg" data:imageData];

    PFObject *userPhoto = [PFObject objectWithClassName:@"Photo"];
    [userPhoto setObject:imageFile forKey:@"image"];

    // Set the access control list to current user for security purposes
    userPhoto.ACL = [PFACL ACLWithUser:[PFUser currentUser]];

    [userPhoto setObject:user forKey:@"user"];

    [userPhoto saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (!error) {
            NSLog(@"sucess");
        }
        else{
            // Log details of the failure
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
        [[ConnectionManager sharedManager] removeload];
    }];
