iPhone刘海屏适配

1、判断是否是刘海屏

//判断是否是刘海屏
BOOL isIPhoneNotchScreen(void)
{
    if (__IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_11_0) {
        return NO;
    }
    
    /* iPhone8 Plus  UIEdgeInsets: {20, 0, 0, 0}
     * iPhone8       UIEdgeInsets: {20, 0, 0, 0}
     * iPhone XR     UIEdgeInsets: {44, 0, 34, 0}
     * iPhone XS     UIEdgeInsets: {44, 0, 34, 0}
     * iPhone XS Max UIEdgeInsets: {44, 0, 34, 0}
     */
    UIEdgeInsets safeAreaInsets = UIApplication.sharedApplication.windows.firstObject.safeAreaInsets;
    
    CGFloat bottomSpace = 0;
    switch (UIApplication.sharedApplication.statusBarOrientation) {
        case UIInterfaceOrientationPortrait:{
            bottomSpace = safeAreaInsets.bottom;
        }break;
        case UIInterfaceOrientationLandscapeLeft:{
            bottomSpace = safeAreaInsets.right;
        }break;
        case UIInterfaceOrientationLandscapeRight:{
            bottomSpace = safeAreaInsets.left;
        } break;
        case UIInterfaceOrientationPortraitUpsideDown:{
            bottomSpace = safeAreaInsets.top;
        }break;
        default:
            bottomSpace = safeAreaInsets.bottom;
            break;
    }
    return bottomSpace > 0 ? YES : NO;
}

2、获取导航栏高度

//获取导航栏高度
CGFloat getNavigationBarHeight(void)
{
    if (__IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_11_0) {
        return 64.0f;
    }
    UIEdgeInsets safeAreaInsets = UIApplication.sharedApplication.windows.firstObject.safeAreaInsets;
    CGFloat topSpace = 0;
    switch (UIApplication.sharedApplication.statusBarOrientation) {
        case UIInterfaceOrientationPortrait:{
            topSpace = safeAreaInsets.top;
        }break;
        case UIInterfaceOrientationLandscapeLeft:{
            topSpace = safeAreaInsets.left;
        }break;
        case UIInterfaceOrientationLandscapeRight:{
            topSpace = safeAreaInsets.right;
        } break;
        case UIInterfaceOrientationPortraitUpsideDown:{
            topSpace = safeAreaInsets.bottom;
        }break;
        default:
            topSpace = safeAreaInsets.top;
            break;
    }
    return topSpace + 44.0f;
}

3、获取tabBar高度

//获取tabBar高度
CGFloat getTabBarHeight(void)
{
    if (__IPHONE_OS_VERSION_MAX_ALLOWED < __IPHONE_11_0) {
        return 49.0;
    }
    
    UIEdgeInsets safeAreaInsets = UIApplication.sharedApplication.windows.firstObject.safeAreaInsets;
    CGFloat bottomSpace = 0;
    switch (UIApplication.sharedApplication.statusBarOrientation) {
        case UIInterfaceOrientationPortrait:{
            bottomSpace = safeAreaInsets.bottom;
        }break;
        case UIInterfaceOrientationLandscapeLeft:{
            bottomSpace = safeAreaInsets.right;
        }break;
        case UIInterfaceOrientationLandscapeRight:{
            bottomSpace = safeAreaInsets.left;
        } break;
        case UIInterfaceOrientationPortraitUpsideDown:{
            bottomSpace = safeAreaInsets.top;
        }break;
        default:
            bottomSpace = safeAreaInsets.bottom;
            break;
    }
    return bottomSpace + 49.0;
}
