Cant replace string in NSMutableString

Question

This is my string:

2011-10-07T08:55:16-05:00

I am trying to remove the colon with this code:

NSRange range = NSMakeRange(dateString.length-3, 1);
NSString *temp = [dateString substringWithRange:range];
if ([temp isEqualToString:@":"])
    [dateString replaceCharactersInRange:range withString:@""];

My code enters the if statement, so I know that it found the colon. But it crashes with no errors on the last line. What am I doing wrong?

try this :

NSMutableString *dateString = [NSMutableString stringWithString:@"2011-10-07T08:55:16-05:00"];

NSRange range = NSMakeRange(dateString.length-3, 1);
NSString *temp = [dateString substringWithRange:range];
if ([temp isEqualToString:@":"])
    [dateString replaceCharactersInRange:range withString:@""];
