Opening URLs in chrome

On iOS device, by default the framework will launch Safari upon calling openURL method.

Below are the launch schemes for google chrome so that we can launch the Chrome browser directly from the app.

NSURL *inputURL = ;

    NSString *scheme = inputURL.scheme;

    

    // Replace the URL Scheme with the Chrome equivalent.

    NSString *chromeScheme = nil;

    if ([scheme isEqualToString:@"http"]) {

        chromeScheme = @"googlechrome";

    } else if ([scheme isEqualToString:@"https"]) {

        chromeScheme = @"googlechromes";

    }

    

    // Proceed only if a valid Google Chrome URI Scheme is available.

    if (chromeScheme) {

        NSString *absoluteString = [inputURL absoluteString];

        NSRange rangeForScheme = [absoluteString rangeOfString:@":"];

        NSString *urlNoScheme =

        [absoluteString substringFromIndex:rangeForScheme.location];

        NSString *chromeURLString =

        [chromeScheme stringByAppendingString:urlNoScheme];

        NSURL *chromeURL = [NSURL URLWithString:chromeURLString];

        

        // Open the URL with Chrome.

        [[UIApplication sharedApplication] openURL:chromeURL];

    }
