Valid URL string as NSUrl becomes null

Question

another issue where I seem to have found a solution for ObjC but not MonoTouch.

I want to get NSUrl from a url (as a string).

A string can contain spaces and backslashes.

Why does NSUrl return null for such a string, even if these are valid URLs in the browser?

For example: NSUrl foo = NSUrl.FromString (@ " http://google.com/search ? \ Query");

foo == null

Any suggestions?

[NSURL URLWithString: [googlSearchString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];

Answer 2

You probably need to process the string first with

stringByAddingPercentEscapesUsingEncoding: 

... so that it can handle a valid URL.

Answer 3
