Better url escape

[mureev]

I can suggest to use "@"!'"();:@&=+$,/?%#[]% " instead of "@"!'();:@&=+$,/?%#[]" in encodeByAddingPercentEscapes methos

What situations does the current one fail under?

I'm just not sure how an NSURL would have an unescaped quote in it. In this example below, urlToShare is nil because NSURL expects to be given a valid URL.

NSURL *urlToShare = [NSURL URLWithString:@"http://example.com/\"quotes\"/"];

I get this string from stakoverflow a long time ago and I don't know about quotes too. But there is more important difference - space char;
