Why reinvent the wheel? Just use an NSNumberFormatter.

double someNumber = 1000.0;

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
// Use decimal style - this includes grouping
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
// Force two decimal places
[formatter setMinimumFractionDigits:2];
[formatter setMsximumFractionDigits:2];

NSString *formattedNumber = [formatter stringFromNumber:@(someNumber)];

This also has the advantage that it will format the number properly based on the user's locale.

It will appears as 1,000.00 or 1.000,00 or 1 000,00 or some other proper format for the user.
