Hello, im a java developer, now trying to learn objective c. I got one problem while developing app. The concept of app is to download some html page and to parse values from tables. On java it is easy to parse some substring: Code: You must Login or Register to view and contribute code!

Code: s="<td>Hello world</td>"; s=s.substring(s.indexOf("<td>")+4); s=s.substring(0,s.indexOf("</td>")); So string s will contain Hello World. But i did not find such method as substring in NSString class. How can i do such task in Ob-C?
