IOS：導航欄 - 重新加載視圖控制器

Question

當我們從導航欄返回視圖控制器時，是否有任何方法可以發佈？

我想從導航欄返回到屏幕時重新加載NIB。

可能嗎？

感謝

你可能想看看viewWillAppear:animated和viewDidAppear:animated方法UIViewController。每次推送視圖控制器時都會調用它們。

- (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. 
}
