    //getting value from text field when entered
    charlieInputSelf = [sender stringValue];

           


        

Answer 1

The Most efficent way to do this is by using this

// set it into an NSString
NSString *yourText = yourVariable.text;

if([theText length] == 0])
{
 // Your Code if it is equal to zero
}
else
{
// of the field is not empty

}
