Answer 1

Try this to remove commas and get an NSNumber from string,

NSNumber *numberObj = [NSNumber numberWithFloat:[[string stringByReplacingOccurrencesOfString:@"," withString:@""] floatValue]];

Then to get the string with comma in number,

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setGroupingSeparator:@","];
[formatter setGroupingSize:3];
NSString *formattedString = [formatter stringFromNumber:[NSNumber numberWithFloat:floatNumber]];
