Scheme Deep Link

點擊URL轉跳APP的某頁面或是啟動某項功能
比如Line所釋出的 line://msg/text/+文字
可以傳送訊息直接帶文字過去Line APP啟動
以下簡易示範

stevenApp://test.com:80/12345;param?account=1&password=2#fragment
Swift

監聽Scheme點擊事件

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    let result = ApplicationDelegate.shared.application(app, open: url, options: options)
    if url.host == nil {
        return true;
    }
    print("url:\(url)")
    print("scheme:\(url.scheme ?? "")")
    print("host:\(url.host ?? "")")
    print("port:\(url.port ?? 0)")
    print("pathComponents:\(url.pathComponents)")
    print("query:\(url.query ?? "")")
    print("fragment:\(url.fragment ?? "")")
    return result
}
Swift
  • scheme : 你APP設定得連結，比如Line就是line://
  • host : 主URL
  • port : port號 有的沒有就是nil
  • pathComponents : 子分層地址
  • query : GET 傳送參數
  • fragment : 分層
url:stevenApp://test.com:80/12345;param?account=1&password=2#fragment
scheme:stevenApp
host:test.com
port:80
pathComponents:["/", "12345;param"]
query:account=1&password=2
fragment:fragment
Swift

url query解析器

擴展一個URL+extension
自動把Get傳得參數轉為Dictionary

extension URL {
    /// 解析URL GET轉Dictionary
    var params: [String: String]? {
        if let urlComponents = URLComponents(url: self, resolvingAgainstBaseURL: true) {
            if let queryItems = urlComponents.queryItems {
                var params = [String: String]()
                queryItems.forEach{
                    params[0.name] =0.value
                }
                return params
            }
        }
        return nil
    }
}
Swift

AppDelegate

print("url params:\(String(describing: url.params))")
Swift
