I am not entirely sure whether this is as clean as it can be, but this is
working for me. Might be a starting point, please give me feedback if this can
be improved..
In your Objective-C class, put in appropriate method:
NSString *path = [[NSBundle mainBundle]
pathForResource:@"javascriptFileName" ofType:@"js"];
NSString *jsCode = [NSString stringWithContentsOfFile:path
encoding:NSUTF8StringEncoding error:nil];
[self.myWebView stringByEvaluatingJavaScriptFromString:jsCode];
[self.myWebView
stringByEvaluatingJavaScriptFromString:@"javascriptFunction()"];
NSString *someString = [self.myWebView
stringByEvaluatingJavaScriptFromString:@"javascriptFunction()"];
In javascriptFileName.js file that has been added to the NSBundle:
function javascriptFunction() {
// javascript logic here
return someReturnValue;
}
By the way, if you want to catch javascript click events, then I think you'd
need to have that event trigger a return value. That way, your Objective-C
class can interpret the javascript and act accordingly…
