Code Block - (void)viewDidLayoutSubviews{
  [super viewDidLayoutSubviews];
  UIButton* button =[[UIButton alloc] initWithFrame:CGRectMake(0, 200, [UIScreen mainScreen].bounds.size.width, 300)];
  [button setBackgroundColor:[UIColor orangeColor]];
  [button addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];
}

I just add a UIButton with 300 height. When I run in iphone 6 plus and iphone XR, the UIButton's height in iphone 6 plus is biggger than in iphone XR. Why?

viewDidLayoutSubviews is not the right place to create objects,

you will create new objects each time to have to layout
your risk creating infinite recursive loops

you should do it either in viewDidLoad or in viewWillAppear.

How much bigger is the button ?
Does it occur in simulator or device ?
