numberFormatter = [[NSNumberFormatter alloc] init]; 
[numberFormatter setNumberStyle: NSNumberFormatterNoStyle]; 
[numberFormatter setGroupingSize:3]; 
[numberFormatter setGroupingSeparator:@","]; 
[numberFormatter setUsesGroupingSeparator:YES]; 
number= [NSNumber numberWithInt:[textFieldString intValue]]; 
NSString *numberString = [NSString stringWithFormat:@"$%@",[numberFormatter stringForObjectValue:number]];

Answer 3

試試這個碼。它可以幫助你

NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init] autorelease]; 
    [numberFormatter setFormat:@"#,###"]; 
    NSNumber *averageResponseTime = [NSNumber numberWithInt:[textfield.text intValue]]; 

//If you print text 


[NSString stringWithFormat: @"%@ms",[numberFormatter stringForObjectValue:averageResponseTime]];
