Here small snippet for UITextFieldDelegate:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if([[textField text] length] > 0) {
        if([[textField text] characterAtIndex:([[textField text] length]-1)] == ' ' && 
           [string isEqualToString:@" "]) return NO;
    }
    return YES;
}
