Question

I build an iPhone app and notice that there is the Analyze tool in XCode.

I have this code:

View * view = [[View alloc]initWithFrame:self.view.frame title:currentItem.name id:currentItem.idStr];
self.menuView = [[MenuView alloc]init];
self.menuView.contentView = view;
[view release];

and the View Property:

@property (retain,nonatomic) MenuView * menuView;

And when i make a Analyze on the project i get this potential leak warning.
And i want to know if it’s ok and the analyze just warn me? or i made a mistake with the code.

---

Edit

And if i do some thing like this :

@property (retain, nonatomic) IBOutlet UISlider *progressSlider;

.

self.progressSlider = [[[UISlider alloc]initWithFrame:CGRectMake(58, 12, 191, 23)]autorealese];
[view addSubview:self.progressSlider];

and in the dealloc:

[progressSlider realese];

This is what i sould to do too? or it’s wrong?

Answer 1

If you retain a property you should send it a release message in your dealloc method:

- (void)dealloc {
    [menuView release];
    [super dealloc];
}

Also, you alloc/init when you assign the menuView property. The init method gives you a retain count of one. Setting the property gives you a retain count of two. You should have a matching number of releases. Your setup code should look like this:

MenuView *m = [[MenuView alloc] init];
self.menuView = m;
[m release];
