UIView *MainView = [[UIViewalloc]initwithframe: CGRectMake    (0,0,self.view.frame.size.width, self.view.frame.size.height) ];
TopView.backgroundColor = [UIColor grayColor];

To add view above view:-

UIView *UnitsView = [[UIView alloc]initwithframe:CGRectMake(0,0,100,100)];
UnitsView.backgroundColor = [UIColor grayColor];
[self.view addSubView:UnitsView];


UIView *SubUnit = [[UIView alloc]initwithframe:CGRectMake(0,0,50,50)];
SubUnit.backgroundColor = [UIColor greenColor];
[self.UnitsView addSubView:SubUnit];
