ios - 如何修复 SafeAreaLayoutGuide

Question

我正在用 Canvas 制作游戏。游戏因为一流而被剪裁，我试过 SafeAreaLayoutGuide 但没有任何反应。请查看下面的代码，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);
}

红色进入顶部槽口。我的意思是全屏。如何解决？

您需要有全屏父 View 。然后您可以将 OpenGLView 添加为 subview ，并将其约束连接到父 View 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);
}
