Objective C: “Property implementation must have its declaration in interface”

Question

I have the following code:

//RootViewController.h:

#import 

@interface RootViewController : UIViewController{
    IBOutlet UITe         


        

Answer 1

You need to declare the property with @property in your interface.

@property( nonatomic, retain ) IBOutlet UITextField * login_uname;

Here, non-atomic is used because it's an IBOutlet. Also note the property has the retain modifier, meaning you are responsible to release the object when you don't need it anymore.
