How does JavaScript call the objective-C method?

Interaction between JavaScript and objc

How does one implement JavaScript to call an interface inside objc?

I implemented it in this way.

For example, an entry
<Input type = "button" id = "enter" value = "enter" onclick = "testclick ('printlog1: log2: ', 'ddddd', 'aaaaa '); "/>

JS
Function testclick (CMD, parameter1, parameter2)
{
Alert (1 );
Document. Write (date ());
Window. Location. href = "objc: //" + cmd + ":/" + parameter1 + ":/" + parameter2;
}

Note: window. location. href = "objc: //" + cmd + ":/" + parameter1 + ":/" + parameter2; // cmd indicates that the method name must not contain spaces, the latter is the attached Parameter
The parameter format depends on your needs.


-(Bool) webview :( uiwebview *) webview shouldstartloadwithrequest :( nsurlrequest *) Request navigationtype :( uiwebviewnavigationtype) navigationtype
{
Nsstring * urlstring = [[request URL] absolutestring];

Nsarray * urlcomps = [urlstring componentsseparatedbystring: @ ": //"];

If ([urlcomps count] & [[urlcomps objectatindex: 0] isequaltostring: @ "objc"])
{

Nsarray * arrfucnameandparameter = [(nsstring *) [urlcomps objectatindex: 1] componentsseparatedbystring: @ ":/"];
Nsstring * funcstr = [arrfucnameandparameter objectatindex: 0];

If (1 = [arrfucnameandparameter count])
{
// No Parameters
If ([funcstr isequaltostring: @ "dofunc1"])
{

/* Call the local function 1 */
Nslog (@ "dofunc1 ");

}
}
Else
{
// Parameters
If ([funcstr isequaltostring: @ "printlog1: log2:"])
{
[Self printlog1: [arrfucnameandparameter objectatindex: 1] log2: [arrfucnameandparameter objectatindex: 2];
}
}
Return no;
}
