How about this?

NSString *firstNameActual = firstNameTF.text;
NSString *firstNameTrimmed = [firstNameTF.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

if ([firstNameActual isEqualToString:firstNameTrimmed]) {
    // there is no space at start or end
} else {
    // there are spaces at start or end
}
