我正在用画布制作游戏。游戏因为一流而被剪辑,我试过SafeAreaLayoutGuide,但什么也没发生。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);

红色进入***。我是说全屏。如何解决?

【问题讨论】:

如果我理解正确,您需要将 glView 捏到其超级视图的安全区域。像这样 [glView.leadingAnchor constraintEqualToAnchor:self.safeAreaLayoutGuide.leadingAnchor].active = YES; 【参考方案1】:

您需要有一个全屏父视图。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);
