Validate against empty UITextField?

Question

What is the value of a UITextField when it is empty? I can't seem to get this right.

I've tried (where `phraseBox' it the name of the said UITextField

if(phraseBox.text != @""){

and

if(phraseBox.text != nil){

What am I missing?

Answer 1

// Check to see if it's blank
if([phraseBox.text isEqualToString:@""]) {
  // There's no text in the box.
}

// Check to see if it's NOT blank
if(![phraseBox.text isEqualtoString:@""]) {
  // There's text in the box.
}
