Let’s say you have to send a POST HTTP request that contains UTF-8 characters. But the problem is that url will not be formed if you simply try to generate it from a string. I managed that problem in the following way:
</p>
<pre>NSLog(@"The urlString is: >>>>>%@<<<<<", urlString);
NSString* escapedUrlString =[urlString stringByAddingPercentEscapesUsingEncoding:
NSUTF8StringEncoding];
NSLog(@"The urlString is: >>>>>%@<<<<<", escapedUrlString);
NSURL* url = [NSURL URLWithString: escapedUrlString];
NSLog(@"The url is: >>>>>%@<<<<<", url);</pre>
