Caption of tabBarItem - Stack Overflow

Question

 foodViewController *food =[[foodViewController alloc]init];
    food.view.backgroundColor=[UIColor redColor];
    food.tabBarItem.title=@"觅食";
    
    food.tabBarItem= [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemSearch tag:1];

The title remains unchanged. How to solve it? I want to use UITabBarSystemItemSearch but how to change the title?
