變量連接到Interface Builder時釋放內存不釋放時，如何修復？

Question

這個視圖控制器會消耗內存，當視圖釋放所有內存不空閒時 如何釋放內存？

@interface Agro01ViewController : UIViewController<UIScrollViewDelegate> { 

    NSInteger picIndex; 
    BOOL isOverrideing; 
    NSTimer *myTimer; 
    NSInteger maxPicture; 
} 

@property (nonatomic, retain) IBOutlet UIScrollView *myscrollView;

擺脫：

- (void)viewDidUnload { 
self.simgView = nil; 
self.simgView3 = nil; 
self.myscrollView = nil; 
self.myscrollView3 = nil; 
self.Landscape = nil; 
self.Portrait = nil; 
self.imgView = nil; 
self.imgView2 = nil; 
self.imgView3 = nil; 
self.imgView4 = nil; 
self.imgView5 = nil; 
self.imgView6 = nil; 
self.imgView7 = nil; 
self.imgView8 = nil; 
[super viewDidUnload]; 
} 

你清理出的指針，你想擺脫的對象，之前的dealloc才能進行。讓dealloc處理它。
