Dont try to create a custom method to handle number separator. IOS has built in methods for that and it works depending on the user Country.

You need to do something like this:

NSNumberFormatter *nf;
nf = [[NSNumberFormatter alloc] init];
[nf setMaximumFractionDigits:2]; // to show only two decimal places
NSNumber *num =[nf numberFromString:@"123456.789"];
NSLog([nf stringFromNumber:num]);

Check apple's doc for NSNumberFormatter , for more info and options.
