Add a subview (created in xib) into a UIView

Question

I have a UIView, that contains 3 other subviews. At the beginning, I do not add these 3 subviews into the UIView, instead I created them separately as follow:

enter image description here

I want to add the subview dynamically. So I try this code as follow:

Add MainView to UIViewController

UINib *nib = [UINib nibWithNibName:@"MainView" bundle:nil];
MainView* mainView = [[nib instantiateWithOwner:self options:nil] objectAtIndex:0];
[self.view addSubview:mainView];

It's ok so far. But now, in the MainView class, I add the subView, I got crash

UINib *nib = [UINib nibWithNibName:@"SubView1" bundle:nil];
SubView1* subView1 = [[nib instantiateWithOwner:self options:nil] objectAtIndex:0];
[self addSubview:subView1];

What's wrong with my code?

You can have 3 subviews in your main view and call that views when needed. Hide remaining ones and bringsubviewtofront the view which you want to show. — Manthan

I don't know why it crash cause I had never use this type. So what I suggest you try the below

UIView *mainView=[[[NSBundle mainBundle] loadNibNamed:@"yourNibName" owner:self options:nil] objectAtIndex:0];
[[self view] addSubview:mainView];

In the same way

UIView *subView1=[[[NSBundle mainBundle] loadNibNamed:@"yourNibName" owner:self options:nil] objectAtIndex:1];
[mainView addSubview:subView1];

UIView *subView2=[[[NSBundle mainBundle] loadNibNamed:@"yourNibName" owner:self options:nil] objectAtIndex:2];
[mainView addSubview:subView2];

UIView *subView3=[[[NSBundle mainBundle] loadNibNamed:@"yourNibName" owner:self options:nil] objectAtIndex:3];
[mainView addSubview:subView3];

I am sure it'll defiantly work
