在iOS中，您可以在PFOauth1FlowDialog.m中修改Parse的源代码.

In iOS, you can revise the source code of Parse in PFOauth1FlowDialog.m

- (void)loadURL:(NSURL *)url queryParameters:(NSDictionary *)parameters   {
    NSMutableDictionary *_parameter = [[NSMutableDictionary alloc] init];
    [_parameter setObject:@"true" forKey:@"force_login"];
    [_parameter addEntriesFromDictionary:parameters];
    _loadingURL = [[self class] _urlFromBaseURL:url queryParameters:_parameter];
    NSURLRequest *request = [NSURLRequest requestWithURL:_loadingURL];
    [_webView loadRequest:request];
}

然后一切都应该正常工作，并且在Android中也应该工作.

Then everything should work fine, And this should also work in Android.
