Answer 1

The easiest way to do it.

Create new NSString without " " (spaces)

NSString *textWithoutSpaces = [self.textField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

Now you have string without spaces. You just have to check is this string empty or not.

if (textWithoutSpaces != 0) {
 /* not empty - do something */
} else {
  /* empty - do something */
}
