I'm currently fairly comfortable with Mac development but still
struggling to learn iPhone. I'm seeing differences in how things are
coded and I'm not seeing many explanations as to why the difference.
For instance, on the Mac, in Interface Builder, I have a text field,
I link it up with the code using:
@interface someClass : NSObject
{
IBOutlet NSTextField *myLabel;
}
Then in the implementation I can call [myLabel setStringValue:
@"something new"]. No need to create the methods, alloc, init or
release anything, etc.
In iPhone examples many or all of them have:
@interface myViewController : UIViewController
{
IBOutlet UILabel *myLabel;
}
@property (retain, nonatomic) UILabel *myLabel;
and then @synthesize myLabel in the implementation. I've even seen
where the dealloc method will then release the object.
This should actually be
@interface MyViewController : UIViewController
{
UILabel *myLabel;
}
@property (retain, nonatomic) IBOutlet UILabel *myLabel;
The advantage of this approach is that it makes the memory management
semantics explicit and clear, and it works consistently across all
platforms for all nib files.
