ios - 来电消失查看事件

Question

我里面有一个ContainerView和ViewController。然后，当用户单击按钮时，我隐藏此 ContainerView (myContainerView.hidden = true)，但 ViewController 继续工作，导致卡住。我如何隐藏 ContainerView 和 stop ViewController 内部，以触发 viewWillDisappear 方法。我不需要每次都杀掉它。

当您更改选项卡时，UITabBarController 具有相同的行为，它只会停止 Controller 。

Answer 1

Calling the standard function removeFromParentViewController we remove the current Detail Controller from the Container hierarchy. When this function is called, the function didMoveToParentViewController is automatically called with nil as parameter on the Detail Controller.

再次添加

- (void)presentDetailController:(UIViewController*)detailVC{

    //0. Remove the current Detail View Controller showed 
    if(self.currentDetailViewController){
        [self removeCurrentDetailViewController];
    }

    //1. Add the detail controller as child of the container
    [self addChildViewController:detailVC];

    //2. Define the detail controller's view size
    detailVC.view.frame = [self frameForDetailController];

    //3. Add the Detail controller's view to the Container's detail view and save a reference to the detail View Controller
    [self.detailView addSubview:detailVC.view];
    self.currentDetailViewController = detailVC;

    //4. Complete the add flow calling the function didMoveToParentViewController
    [detailVC didMoveToParentViewController:self];

}
