ios - 将图像上传到解析

Question

我正在尝试为我在 Parse 中的用户上传图像作为 PFFile。我没有收到任何错误，但文件不存在？我究竟做错了什么？

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    self.imageToUpload = info[UIImagePickerControllerOriginalImage];
    self.profileImageView.image = self.imageToUpload;

    NSData *pictureData = UIImagePNGRepresentation(self.imageToUpload);

    PFFile *image = [PFFile fileWithName:@"img" data:pictureData];
    [image saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (succeeded) {
            PFUser *user = [PFUser currentUser];
            user[@"picture"] = image;
            [picker dismissViewControllerAnimated:YES completion:nil];
        }
        else {
            [[[UIAlertView alloc] initWithTitle:@"Error" message:[error userInfo][@"error"] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
        }
    } progressBlock:^(int percentDone) {
        NSLog(@"Uploaded: %d%%", percentDone);
    }];
}

您实际上并没有保存 user ，因此不会建立用户和新文件之间的链接。这使文件漂浮在周围，没有连接到任何东西。

基本上，保存 user设置后[@"picture"] = image .
