I have a UITableView that's part of a Navigation-based Application. There's
one .xib, a DrinkDetailViewController class (.m .h files) and an
AddDrinkViewController class which inherits from DrinkDetailViewController.
Both share the same view, which contains a UITextField, two UITextViews, and
some UILabels. The DrinkDetailViewController.h declares three IBOutlets as
follows:
#import UIKit/UIKit.h
@interface DrinkDetailViewController : UIViewController
{
IBOutlet UITextField *nameField;
IBOutlet UITextView *ingredientsView;
IBOutlet UITextView *directionsView;
...
}
@end
so that I can access the UITextField, and the two UITextViews. IB shows in
the inspector window, that the UITextField, and UITextViews have a BOOL
enabled property (controlled by a checkbox labeled Enabled). But the
following doesn't work:
...
nameField.enabled = YES;
ingredientsView.enabled = YES;
directionsView.enabled = YES;
...
in the viewDidLoad: method of AddDrinkViewController. I unchecked the enabled
box for these controls as the normal use of the view is just to display drink
information, not for data entry. The AddDrinkViewController re-uses the view
for data entry, and I want to re-enable the fields, but only when the view
(xib) is used/loaded by the AddDrinkViewController. I looked in the docs for
UITextField, but didn't even see a reference to an enabled property. Is this
another of those view-within-a-view problems?
Theenabledproperty is defined in UIControl --- the super-class of
UITextField . . .
This is a good time for a plug for Xcode's incredibly useful but oft skipped
over Class Browser,
the second item in Xcode's Project menu . . .
