在window上添加view模拟lunchImage

代码部分
#pragma mark 各种尺寸的图片
#define foureSize ([UIScreen mainScreen].bounds.size.height == 480)
#define fiveSize ([UIScreen mainScreen].bounds.size.height == 568)
#define sixSize ([UIScreen mainScreen].bounds.size.height == 667)
#define sixPSize ([UIScreen mainScreen].bounds.size.height > 668)

    // Override point for customization after application launch.
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    [self.window makeKeyAndVisible];
    
#pragma mark 这部分一定要写在下面
    self.window.rootViewController = [[BlueViewController alloc] init];
    [self setStartAnamation]; //添加登录图片
    
    return YES;

#pragma mark 添加页面显示的动画图片
