如何检查设备是否需要SafeArea？(需要底部/顶部填充)

if #available(iOS 11.0, *) {
    let window = UIApplication.shared.keyWindow
    let safeAreaInsets = window?.safeAreaInsets
    if safeAreaInsets?.bottom ?? 0 > 0 || safeAreaInsets?.top ?? 0 > 0 {
        // 设备需要底部或顶部填充
    } else {
        // 设备不需要底部或顶部填充
    }
}

if #available(iOS 11.0, *) {
    let safeAreaInsets = UIApplication.shared.windows.first?.safeAreaInsets
    if safeAreaInsets?.bottom ?? 0 > 0 || safeAreaInsets?.top ?? 0 > 0 {
        // 设备需要底部或顶部填充
    } else {
        // 设备不需要底部或顶部填充
    }
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    ViewCompat.setOnApplyWindowInsetsListener(view, new OnApplyWindowInsetsListener() {
        @Override
        public WindowInsetsCompat onApplyWindowInsets(View v, WindowInsetsCompat insets) {
            int bottomInset = insets.getSystemWindowInsetBottom();
            int topInset = insets.getSystemWindowInsetTop();
            if (bottomInset > 0 || topInset > 0) {
                // 设备需要底部或顶部填充
            } else {
                // 设备不需要底部或顶部填充
            }
            return insets;
        }
    });
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    View view = getWindow().getDecorView();
    WindowInsets windowInsets = view.getRootWindowInsets();
    int bottomInset = windowInsets.getSystemWindowInsetBottom();
    int topInset = windowInsets.getSystemWindowInsetTop();
    if (bottomInset > 0 || topInset > 0) {
        // 设备需要底部或顶部填充
    } else {
        // 设备不需要底部或顶部填充
    }
}
