CkoHttp *http = [[CkoHttp alloc] init];

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).

// To delete a file or folder, send a DELETE request like this:
// If not using "me", then the URL path should be /v1.0/users/{id | userPrincipalName}/...
// DELETE /v1.0/me/drive/root:/{item-path}

    NSLog(@"%@",http.LastErrorText);
    return;
}

// A 204 response (with no response body) indicates success.
if ([http.LastStatus intValue] == 204) {
    NSLog(@"%@",@"DriveItem deleted.");
}
