当我在没有动画的情况下推送 UIViewController 时无法设置插座
我有一个 UINavigationController，我可以使用 pushViewController:animated: 将 UIViewController 推送到它上面。之后，我在该传入视图上调用一个方法来设置它的一些 IB 出口。不幸的是，这些只有在我为视图设置动画时才会设置。
所以这会起作用：
MyViewController *newView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[self.navigationController pushViewController:newView animated:YES];
[newView updateOutletsForObject:myObject];
但这不会：
MyViewController *newView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[self.navigationController pushViewController:newView animated:NO];
[newView updateOutletsForObject:myObject];
有谁知道为什么会发生这种情况？提前致谢。
I have a UINavigationController with which I push UIViewControllers onto using pushViewController:animated:. After this, I call a method on that incoming view to set some of its IB outlets. Unfortunately, these only get set when I animate the view.
So this will work:
MyViewController *newView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[self.navigationController pushViewController:newView animated:YES];
[newView updateOutletsForObject:myObject];
But this won't:
MyViewController *newView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil];
[self.navigationController pushViewController:newView animated:NO];
[newView updateOutletsForObject:myObject];
Does anyone know why this would be happening? Thanks in advance.

在我看来，父视图控制器不应该设置子视图控制器。您应该在子视图控制器的
-viewDidLoad中处理 IBOutlet 连接。It seems to me that the parent view controller shouldn't be setting up the child's outlets. You should be handling IBOutlet connections in
-viewDidLoadof the child view controller.
