拍摄图片

我正在使用此问题中的代码拍摄图片： Scaling UIImage with a UIIImagePicker's CGAffineTransform and Saving to Parse SDK

将UIImage转换为NSData＆amp;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会出现挤压。当我查看数据库中的图像时，高度和宽度似乎相反。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];
    }];

使用Parse SDK保存图像
