Substring from NSString [closed]

Question

I am using NSString and I want to get a substring of it that contains the first 20 characters of my string. How can I do that?

Answer 1

You can use substringToIndex.

NSString *mystring = @"This is a test message having more than 20 characters";
NSString *newString = [mystring substringToIndex:20];
NSLog(@"%@", newString);

Answer 2

NSString *str = @"123456789012345678901234";
NSString *subStr = [str substringWithRange:NSMakeRange(0, 20)];

Answer 3

NSString *string = @"I am having a simple question.I am having NSString and i want a substring of it that contains first 20 ";
NSString *first20CharString = [string substringToIndex:20];
