对象必须是PHAsset类型

Question

我使用此代码删除图片选择器选择的照片应用中的图片。 选择多个图像后，它将返回assetArray中的所选图像。 现在我想删除那些图像，但它会给出错误＆＃34;对象必须是PHAsset类型＆＃34;

 - (void)assetsPickerController:(GMImagePickerController *)picker didFinishPickingAssets:(NSArray *)assetArray
     {
      [picker.presentingViewController dismissViewControllerAnimated:YES completion:nil];
NSLog(@"===%@===",assetArray);
void (^completionHandler)(BOOL, NSError *) = ^(BOOL success, NSError *error) {
    if (success) {
        dispatch_async(dispatch_get_main_queue(), ^{
            [[self navigationController] popViewControllerAnimated:YES];
        });
    } else {
        NSLog(@"Error: %@", error);
    }
};

   // Delete asset from library
      [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
      [PHAssetChangeRequest deleteAssets:@[assetArray]];
} completionHandler:completionHandler];

  NSLog(@"GMImagePicker: User ended picking assets. Number of selected items is: %lu", (unsigned long)assetArray.count);
}

你创建了一个数组数组。只需这样：

[PHAssetChangeRequest deleteAssets:assetArray];
