Override UIViewController's view property

I want to override my MYViewController : UIViewController's setView: method, such that, I do not allow some one to set view's property to nil.

-(void)setView:(UIView*)view {
    if (view == nil)
       //ignore - make no change
    else 
       //default performance
}

How can I do this?

Calling the super class only when you want the default behavior should do the work:

-(void)setView:(UIView*)view {
    if (view == nil) {
       //ignore - make no change
    }
    else {
       //default performance
       [super setView:view];
    }
}

@synthesize view = _view;

-(void)setView:(UIView*)view {
        if (view)
           _view = view;
    }

It could be done as simple as this. If view is not nil, set the variable.
