NSURL URLWithString returns nil

Question

I am stuck in a very obvious method of NSURL class URLWithString I am passing a string and while creating URL it returns nil, my string is perfect. When ever I uses same string in browser then it is working fine. I am using following method to convert NSString to NSURL:

NSURL *url = [NSURL URLWithString:urlString];
//urlString is my perfect string

I have also tried to encode my string first by using following

NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
// using this line my output string when I log url is "url%10%10%10%10%10%10..."

%10 becomes the suffix of my url with around 100+ repetition. If any one has idea what %10 is or what can be done to overcome this problem.

here is my urlString:
comment says too many character but it is obvious that there are not much characters

%10 is a hex code. That's 16 in decimal which is a strange control character. Show where urlString comes from and again, show its exact value. — rmaddy
please see my edited answer, i have posted an image which showing my url string in comment and site is saying too many characters — Syed Ali Salman
Add the following code: NSLog(@"urlString = \"%@\"", urlString); then update your question with the output from that log statement. — rmaddy
%10 = "data link escape" according to w3schools.com/tags/ref_urlencode.asp. Did you try using stringByTrimmingCharactersInSet:? Btw, if you've already found a solution (based on your comments) I think you could post your solution to help others in the future. — Islam Q.

Use below code to resolve your problem.

NSString *str = msgDetail[@"thumbnail"];

NSString* webStringURL = [str stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];

NSURL* url = [NSURL URLWithString:webStringURL];
