IOS：导航栏 - 重新加载视图控制器

Question

从导航栏返回viewcontroller时有什么方法可以释放吗？

当我从导航栏返回屏幕时，我想重新加载 NIB。

有可能吗？

谢谢

您可能想看看UIViewController 中的viewWillAppear:animated 和viewDidAppear:animated 方法。每次将视图控制器推送到显示时都会调用它们。

- (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];
    // Reload your data here, and this gets called
    // before the view transition is complete.
}

- (void)viewDidAppear:(BOOL)animated {

    [super viewDidAppear:animated];
    // Reload your data here, and this gets called
    // after the view transition is complete.
}
