如何调用以json字符串形式传递的函数

Question

I am reading from a backend, a JSON file with parameters which include a function with arguments { "function": {"arg1": 45, "arg2": 73}} . I would like to execute the function using the arguments specified in the JSON string. How would I implement this in Swift 3?

Answer 1

You can execute javascript in an instance of WKWebView and get the result back with WKWebView.evaluateJavaScript(_:completionHandler:) . You need the actual code for the function though, which I don't see in your sample. You can grab the values of the arguments from the JSON with JSONSerialization , SwiftJSON, ObjectMapper or any of the other many JSON libraries.
