iOS-UISearchController 的 Bug 之 A

如下报错：

Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior (<UISearchController: 0x7fb91a72b400>)

点击退出登录时，控制台打印的错误提示.png

解决办法：

-(void)dealloc
{
    /**
     * 解决退出登录时 UISearchController 报错的相关问题
     */
    [self.searchVc.view removeFromSuperview];
}
