Unity如果未做任何处理的话，导出的IPA运行起来的效果，刘海屏这块被自己被覆盖掉

解决方案

在导出的UnityAppController.mm文件中找到-(BOOL)didFinishWithLaunchingWithOptions:(NSDictionary*)launchOptions 方法

竖屏(参数刚好移出刘海的区域)

参数自己可以调节

//    _window         = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen].bounds];
 
    CGRect winSize = [UIScreen mainScreen].bounds;
    //IPHONEX
    if (winSize.size.height / winSize.size.width > 2) 
    {
        winSize.size.height -= 32;
        winSize.origin.y = 32;
    }  
    _window = [[UIWindow alloc] initWithFrame: winSize];
