Hi Guys
Can I just suggest something more?
> @interface Controller : NSObject {
> IBOutlet UIButton *beginButton;
> IBOutlet UIButton *endButton;
> IBOutlet UILabel *nameLabel;
> IBOutlet UILabel *numberLabel;
> MyModel *myModel;

>
> @property (nonatomic, retain) IBOutlet MyModel *myModel;
>
> /* some methods defined here as well */
> @end
From what I have read, and from good object-oriented practice, it would be
better to use Objective-C 2.0 properties for all your outlets. iVars really
should be @private, if you are using them, but don't forget that properties
will synthesize, not only the accessors, but the ivars as well.
@interface Controller : NSObject
{
}
@property IBOutlet UIButton *beginButton;
@property IBOutlet UIButton *endButton;
@property IBOutlet UILabel *nameLabel;
@property IBOutlet UILabel *numberLabel;
@property MyModel *myModel;
/* some methods defined here as well */
@end
@implementation Controller
@synthesize beginButton;
@synthesize endButton;
@synthesize nameLabel;
@synthesize numberLabel;
@synthesize myModel;
@end
Any outlets for controls (top level objects) in the Nib should be released in
the dealloc method only for OS X apps but not for iPhone apps. Setting the
properties to nil will ensure that the synthesized setter will be called, which
releases the previous contents of the synthesized ivar before setting it to nil.
- (void) dealloc
{
beginButton = nil;
endButton = nil;
nameLabel = nil;
numberLabel = nil;
myModel = nil;
[super dealloc];
}
