如何修复SafeAreaLayoutGuide

Question

我正在用画布做游戏。这个游戏因为最高档次而被删减，我尝试过SafeAreaLayoutGuide，但是什么也没发生。请看下面的代码，让我知道我做错了什么。

-(void) createGLView {
    //create our openglview and size it correctly
    OpenGLView *glView = [[OpenGLView alloc] initWithFrame:self.appDelegate.initFrame];

    self.view = glView;
    self.appDelegate.canvas = glView;

    core_init_gl(1);

    glView.backgroundColor = [UIColor redColor];
    glView.translatesAutoresizingMaskIntoConstraints = NO;

    [glView.leadingAnchor constraintEqualToAnchor:glView.safeAreaLayoutGuide.leadingAnchor].active = YES;
    [glView.trailingAnchor constraintEqualToAnchor:glView.safeAreaLayoutGuide.trailingAnchor].active = YES;
    [glView.topAnchor constraintEqualToAnchor:glView.safeAreaLayoutGuide.topAnchor].active = YES;
    [glView.bottomAnchor constraintEqualToAnchor:glView.safeAreaLayoutGuide.bottomAnchor].active = YES;

    int w = self.appDelegate.screenWidthPixels;
    int h = self.appDelegate.screenHeightPixels;
    tealeaf_canvas_resize(w, h);

    NSLOG(@"{tealeaf} Created GLView (%d, %d)", w, h);
}

红色在顶端凹口内。我的意思是全屏。如何解决这个问题？

你需要有一个全屏的父视图。然后，您可以将OpenGLView添加为子视图，并将其约束连接到父视图的safeAreaLayoutGuide。

- (void)createGLView {

    OpenGLView *glView = [[OpenGLView alloc] initWithFrame:self.appDelegate.initFrame];
    [self.view addSubview:glView];

    self.appDelegate.canvas = glView;

    core_init_gl(1);

    glView.backgroundColor = [UIColor redColor];
    glView.translatesAutoresizingMaskIntoConstraints = NO;

    [glView.leadingAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.leadingAnchor].active = YES;
    [glView.trailingAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.trailingAnchor].active = YES;
    [glView.topAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.topAnchor].active = YES;
    [glView.bottomAnchor constraintEqualToAnchor:self.view.safeAreaLayoutGuide.bottomAnchor].active = YES;

    int w = self.appDelegate.screenWidthPixels;
    int h = self.appDelegate.screenHeightPixels;
    tealeaf_canvas_resize(w, h);

    NSLOG(@"{tealeaf} Created GLView (%d, %d)", w, h);
}
