Aquí está mi archivo de cabecera:

@interface MyLocationViewController : UIViewController <CLLocationManagerDelegate, UITextFieldDelegate>

@property (nonatomic, retain) UITextField *textField;

No estoy usando Interface Builder. Cuando se carga la aplicación puedo ver mi campo de texto y el botón. El botón realiza su comportamiento de cambio predeterminado cuando se toca. El campo de texto no es editable: no se puede abrir el teclado haciendo clic en él, no puede escribir, etc.

Ejecuté el método de alguien para determinar si un marco está fuera de los límites de su vista principal y regresó diciendo que estaba fuera de límites, pero no estoy seguro de cómo resolverlo.
