Question

I am trying to use the same system to convert a page with readability bookmarklet as Safari does.

I tried the following:

NSString *searchURL = @"javascript:(%28function%28%29%7Bwindow.baseUrl%3D%27https%3A//www.readability.com%27%3Bwindow.readabilityToken%3D%27%27%3Bvar%20s%3Ddocument.createElement%28%27script%27%29%3Bs.setAttribute%28%27type%27%2C%27text/javascript%27%29%3Bs.setAttribute%28%27charset%27%2C%27UTF-8%27%29%3Bs.setAttribute%28%27src%27%2CbaseUrl%2B%27/bookmarklet/read.js%27%29%3Bdocument.documentElement.appendChild%28s%29%3B%7D%29%28%29)";

NSURL *url =  [NSURL URLWithString:[searchURL stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

NSLog(@"launched readability");


// NSURL *url = [NSURL URLWithString:searchURL];
[webBrowser loadRequest:[NSURLRequest requestWithURL:url]];

but that did not work..

I also tried the following:

[webBrowser stringByEvaluatingJavaScriptFromString:@"function%28%29%7Bwindow.baseUrl%3D%27https%3A//www.readability.com%27%3Bwindow.readabilityToken%3D%27%27%3Bvar%20s%3Ddocument.createElement%28%27script%27%29%3Bs.setAttribute%28%27type%27%2C%27text/javascript%27%29%3Bs.setAttribute%28%27charset%27%2C%27UTF-8%27%29%3Bs.setAttribute%28%27src%27%2CbaseUrl%2B%27/bookmarklet/read.js%27%29%3Bdocument.documentElement.appendChild%28s%29%3B%7D%29%28%29"];

but that did not work either. Could someone point me in the right direction?

You need to unescape the JavaScript (i.e., run it through JavaScript’s unescape function). So instead of what you have there, use: (function(){window.baseUrl='https://www.readability.com';window.readabilityToke‌​n='';var s=document.createElement('script');s.setAttribute('type','text/javascript');s.se‌​tAttribute('charset','UTF-8');s.setAttribute('src',baseUrl+'/bookmarklet/read.js');document.documentElemen‌​t.appendChild(s);})()
