ios - xcode-将登录屏幕输入链接到网站输入

Question

我正在通过XCode构建IOS应用程序，该应用程序具有一个带有用户名和密码输入的登录屏幕。我还有一个带有登录屏幕的网站，可以将您带到我的数据库。我不想通过IOS App与数据库对话。当我点击IOS App上的登录按钮时，我希望用户名和密码字段中的信息可以在网站上填写。我实质上是在IOS应用程序上制作一个外观更好的GUI，该IOS应用程序仅从网站读取其所有信息，就像该网站在数据库中查找信息一样。我不确定如何做到这一点，但是如果您能指出正确的方向，将会很有帮助。

编辑:这是我的IOS快速代码的修改版本。只是想知道您将在哪里添加将IOS应用程序输入链接到网站的代码。

您可以在ViewController上创建隐藏的WKWebview，而WK的URL是您的Web用户登录URL，然后通过View Controller输入将值发布到Webinterface。

NSString *scriptSource = [NSString stringWithFormat:@" document.queryString('#username').value='@%';document.queryString('#password').value='@%';document.querySelector('form').submit;",[inputUsername text],[inputPassword     
WKUserScript *userScript = [[WKUserScript alloc] initWithSource:scriptSource
                                                      injectionTime:WKUserScriptInjectionTimeAtDocumentEnd
                                                   forMainFrameOnly:YES];
[wkWebView.configuration.userContentController addUserScript:userScript];
[wkWebView reload];
