uiview in addsubview, the view does not appear to join

Made a simple example
addsubview
view add another view

viewController1.m

...
viewController2 * v2 = [[viewController2 alloc] init];

[Self.view addsubView: v2.view]
...

Does not show v2.view

But [[self.view subviews] count] but output 1, which means that has joined

This is how it

Thank you

What do you mean?

I use the storyboard,

Pull out viewcontroller2, I just set its background = storyboard blue

Then viewController1 in [self.view addsubView: v2.view]

The results did not show a blue

storyboard, you initialize the controller can not use
viewController2 * v2 = [[viewController2 alloc] init];
Initialize and you do not pass storyboard to generate views.
Instead, use:
UIStoryboard * storyboard = [UIStoryboard storyboardWithName: @ "MainStoryboard" bundle: nil];
viewController2 * v2 = [storyboard instantiateViewControllerWithIdentifier: @ "vc2"];
If so, then you can be initialized using stroyborad design view it.

Thank you,

But after I joined a tabelview, how this tableview can be shown that over that part of the screen, slide out point, it stops sliding, and went back to the first line?
Reply:
May be your UITableView's frame set incorrectly caused. You check again.

Reply:
I did not set the frame

Just a default uitableviewcontroller

But I was in view1 down into a sub-view (sub-view only part of the page), and then in the sub-view of the inner addsubview

Tablecontroller * table = [[Tablecontroller alloc] init];
[Self addChildViewController: table];
[[Self.view viewWithTag: 1] addSubview: table.view];

Always set the rect view it, or will be 0,0,0,0
