Separate number with commas on a string iOS

Question

I have an NSInteger (say with value 60000), when I convert it to string however, I want to get "60,000" instead of "60000". Is there some method to do it? Thanks.

Answer 1

Use a number formatter:

NSNumberFormatter *fmt = [[NSNumberFormatter alloc] init];
[fmt setNumberStyle:NSNumberFormatterDecimalStyle]; // to get commas (or locale equivalent)
[fmt setMaximumFractionDigits:0]; // to avoid any decimal

NSInteger value = 60000;

NSString *result = [fmt stringFromNumber:@(value)];
