ios - What does clear button set UITextField to? -


I have a piece of code that is responding to the text field. I want to see when . The text of the field is empty (either bypassed all the way or cleaned with a small round x button on the right).

If I .text == @ " my code works, the user provides backspace. This does not work if the user has used a clear button.

What does the explicit button set the .text of the text field? (I have logged it out and if I print it between two other characters, I see the blank.)

Maybe me just .text == @ "" ? Maybe .length == 0 or something else?

thanks !

"Clear" button probably sets text property to zero .

Whenever you want to see that the text is free to use: 

  if there is no text (some text is zero in someText.length == 0) {// soneText }

This works for empty code as zero values.

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
