NSArray *escapeChars = [NSArray arrayWithObjects:@" ", nil];

NSArray *replaceChars = [NSArray arrayWithObjects:@"",nil];
int len = [escapeChars count];
NSMutableString *temp = [[textField text] mutableCopy];
for(int i = 0; i < len; i++) {
    [temp replaceOccurrencesOfString: [escapeChars objectAtIndex:i] withString:[replaceChars objectAtIndex:i] options:NSLiteralSearch range:NSMakeRange(0, [temp length])];
}
[textField setText:temp];
return TRUE;
