memory release problem

I have created a view and assigned the view to viewcontroller

UIView *newView=[[UIView alloc] initWithFrame:CGRectMake(0,0,320,460)];

in viewDidLoad method I have assigned the view to the viewcontroller

-(void)viewDidLoad{
  开发者_开发问答  self.view=newView;
    //[view release]; In this case also the application crashing
}

-(void)dealloc{
   [newView release];//IN this case also the application crashing.
   [super dealloc];
}

The crash log is this.

how to release the newView? or else the viewcontroller itself will take care of releasing the newView.

In most circumstances you will do the following:

- (void) loadView {
    // Don't call super here if you assign the view property
    UIView *newView = [[UIView alloc] initWithFrame: [UIScreen mainScreen].applicationFrame];
    self.view = newView;
    [newView release];
    // the view is now owned and retained by the UIViewController
}

Apple recommends you allocate the view, assign and release it in -loadView and don't worry about it in -dealloc. This is important in cases when your view may be purged under low memory conditions.
