Question

In class

@interface StartScene : UIView

I call an instance of

@interface HelpView : UIView {
    GameOverMenu* gorm;
    PlayScene* tView;
}

and use addSubview. I also got huge code here

-(void) removemyself {
    [tView removeFromSuperview];
    [gorm removeFromSuperview];
    [self removeFromSuperview];
}

-(void)restartPlay {
    [tView removeFromSuperview];
    [self playSceneDidLoad];
}

-(void)gameOverDidLoad {
    [tView removeFromSuperview];
    gorm = [[GameOverMenu alloc]initWithFrame:CGRectMake(0, 0, 320, 520)];
    gorm.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backGround.jpg"]];
    [gorm checkScore:Scores];
    [self addSubview:gorm];
}

-(void)playSceneDidLoad {
    [gorm removeFromSuperview];
    tView = [[PlayScene alloc]initWithFrame:CGRectMake(0, 0, 320, 520)];
    tView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"backGround.jpg"]];
    [self addSubview:tView];
    [tView ooneFingerTwoTaps];
}

And two sub classes of HelpView:

@interface PlayScene : HelpView

@interface GameOverMenu : HelpView <UITextFieldDelegate>

In StartScene when I push on a button, an instance of HelpView is created and in init method playSceneDidLoad is called.

Inside the PlayScene there is restart button which calls restartPlay method. When game is lost gameOverDidLoad method is called.

And In both PlayScene and GameOverMenu there are quit button, which calls removemyself method, that are supposed to return player to the main menu.

At first glance it should work fine, but if I press restart button for several times and than try to press Quit, it occurs that the views were not removed from superview, one press on a quit button only now removes them one by one.
And we stop on the HelpView, it didn’t remove itself (even if I try to call [super removeFromSuperview]; somewhere.

I need to remove views correctly in time and to get to the main menu (StartScene) when quit is pressed. I don’t think that a lot of views covering each other is a good variant. What is the problem?

Answer 1

Well I occurs that the point is that if super class’ method is called from the subclass and there is such a command [self removeFromSuperview]; or [(someOtherSubview) removeFromSuperview];, it is subclass that uses self or (someOtherSubview). If our subclass doesn’t have the pointed subView, than the command would do nothing. And if there is [self removeFromSubview];, subclass would remove itself.

Actually I solved this problem by using buttons as subView of superclass.
