Consider the following URL:
http://www.example.com/?utm_source=adsite&utm_campaign=adcampaign&utm_term=adkeyword
We are interested in the query parameter value of utm_term. We can parse the URL using the following code:
| // https://hashaam.com/2017/09/02/get-specific-urlqueryitem-from-urlcomponents | |
| func queryParam(urlString: String?, param: String) -> String? { | |
| guard let urlString = urlString else { return nil } | |
| guard let urlComponents = URLComponents(string: urlString) else { return nil } | |
| guard let queryItems = urlComponents.queryItems else { return nil } | |
| return queryItems.filter { queryItem in | |
| return queryItem.name == param | |
| }.first?.value | |
| } |
And call the function using:
| // https://hashaam.com/2017/09/02/get-specific-urlqueryitem-from-urlcomponents | |
| if let utmTermValue = queryParam(urlString: "http://www.example.com/?utm_source=adsite&utm_campaign=adcampaign&utm_term=adkeyword", param: "utm_term") { | |
| // handle utmTermValue | |
| } |
