Why i mention 2 times the objects i've used?

[nick.keroulis]

Why this:

@interface ViewControllerTextEditor : UIViewController <UITableViewDelegate, UITableViewDataSource>
{
    float fontSize;
    NSString *fontName;
}

@property (nonatomic, assign) float fontSize;

@property (nonatomic, assign) NSString *fontName;

And not just this:

@interface ViewControllerTextEditor : UIViewController <UITableViewDelegate, UITableViewDataSource>

@property (nonatomic, assign) float fontSize;

@property (nonatomic, assign) NSString *fontName;

??? Is the second one approved by apple?

The newer compiler automatically does the extra work in the second example. Previously, you had to declare the ivars and properties separate, as in example one. I believe they both wind up the same compiled code.

Although debugging programs where you only define the properties is painful. You can't see the instance variables in the debugger. I still create instance variables for all my properties for that reason.

You can still do that in the @synthesize line. They don't need to be specified in the .h file. I can't speak to any differences in debugger visibility.
