"Use of undeclared identifier"

Question

I'm pretty new to Objective C. Keep getting this error

"Use of undeclared identifier"

for this line of code:

NSString *textOut1 = textOut.text;

Obviously I am just trying to pull the textbox text. I have declared the following in my h file

@property (weak, nonatomic) IBOutlet UITextField *textOut;

So I cannot understand why I keep getting that damn error. Thanks!

Answer 1

Use this:

NSString *textOut1 = _textOut.text;

Checkout the extra underscore I added in front of textOut
