If you mean a string, [check here](http://stackoverflow.com/questions/1612337/objective-c-nsstring-and-substring). If you mean a float, [check here](http://stackoverflow.com/questions/18063721/ios-objective-c-how-to-get-2-decimal-rounded-float-value) — Jamie Taylor, Dec 05 '13 at 09:03

Like so:

NSString *origString = @"1.2345677";
NSString *subString = [origString substringToIndex:3];

NSString *mainstr = @"1.2345677";
float conver = [mainstr floatValue];
NSString *floatedstr =[NSString stringWithFormat:@"%.2f",conver];

You can also do it with

NSNumberFormatter *format = [[NSNumberFormatter alloc] init];
[format setFormat:@"0.##"];
NSLog(@"%@", [format stringFromNumber:[NSNumber numberWithFloat:25.342]]);
