loading a xib inside a uiview but not responding

Question

I have created a multi-tab page which on click changes view.

One tab includes an order form but I already have a separate order form in my storyboard so I tried to load that form inside the order tab view which I did by coding.

OrderViewController *we = [self.storyboard instantiateViewControllerWithIdentifier:@"OrderViewController"];


we.view.frame = CGRectMake(-8,10, 320, 500);
we.calc.frame = CGRectMake(0,1, 320, 45);

[order addSubview:we.view];
[self.view addSubview:order];

But when I click any button or item on the order form it goes to warning ... dont get it why any help.

Answer 1

[we retain];

因为，（如果我错了，请纠正我）一段时间后，VC将被释放（自动释放）。
