Xcode Assistance with Coding

I am trying to figure out how to do an extension for a html file. I'm new to coding and Xcode and trying to create an app but I have enough experience in coding to understand what goes where and why.

The problem I'm facing is that I need to add an extension to a html file; example

(index.html?lc=uk) instead of (index.html).

I've created a interface and all the other information required but I can't seem to get this part to work. The coding I'm using on the ViewController.m is;

[super viewDidLoad];
    NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webview loadRequest:request];

I've tried adding to the (pathForResource) @"index.html?lc=uk" but when I test the app it doesn't work and gives me an error.

Can someone give me a idea on what I need to do?

Kind Regards,

Seb

[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
path = [NSString stringWithFormat:@"%@?lc=uk", path]; // add the '?lc=uk'
NSURL *url = [NSURL URLWithString:path]; // build URL with string
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];

When I've added this code I get this error 

int main(int argc, char * argv[]) {
@autoreleasepool {
    return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}

}

If i get you right, you need to change the NSString* path like this:

path = [NSString stringWithFormat:@"%@?lc=uk", path];

But if never tried this for a local Path ([NSURL fileURLWithPath:path];) maybe you should use [NSURL URLWithString:path];? Do you have the HTML-File as resource or are you trying to access a remote source?

For a local source the GET-Parameter is eventually even not taken in account, cause there is no PHP or whatever installed as processor for the HTML file.

edit:

your Source:

[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];

new Source:

[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"354"];
path = [NSString stringWithFormat:@"%@?lc=uk", path]; // add the '?lc=uk'
NSURL *url = [NSURL URLWithString:path]; // build URL with string
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webview loadRequest:request];

I hope this will help you.
