Webview & Javsscript
from javascript to ios
javascriptでiosのfunctionをwebkit.messageHandlersでcall
// window.webkit.messageHandlers.[name].postMessage // syntax
window.webkit.messageHandlers.callbackHandler.postMessage('Hello Native!');
ios側で callbackHandler部分を処理するコードを作成
func userContentController(userContentController: WKUserContentController, didReceiveScriptMessage message: WKScriptMessage) {
if(message.name == "callbackHandler") {
print("JavaScript is sending a message : \(message.body)")
}
}
- [name]は whatever you call the script handler
