Answer 1

Method 1: Do it in Objective-C

NSString *str = [NSString stringWithContentsOfURL:wkwebview.URL usedEncoding: NSUTF8StringEncoding error:nil];
NSRange range = [str rangeOfString:@"string to find"];
if (range.location != NSNotFound) {
    //found
}

Method 2: Do it in JQuery

NSString *js = @"var htmlString = $('body').html().toString();
var index = htmlString.indexOf('string to find');
if (index != -1) {alert('found')}";

[wkWebView evaluateJavaScript:js completionHandler:nil];
