我需要尽快刷新视图的内容popViewController [英] I need to refresh the content of a view as soon as I popViewController

问题描述

ViewA 从Coredata加载一些数据，然后推送到下一个 viewB .在 viewB 中，有一些功能可以更改viewA的内容(意味着viewB可以更改核心数据的内容).但是，当我将视图弹出回到 viewA 时，我的内容与以前相同.我怎样才能解决这个问题?

ViewA load some data from Coredata, then push to the next viewB. In viewB, there are some function, that will change the content of viewA (meaning viewB change the content of core data). However, when I pop the view back to viewA, my content stay the same as before. How can I fix this?

推荐答案

在viewA的-(void)viewWillAppear:(BOOL)animated 委托方法中，您可以刷新所需的控件...即，如果您想重新加载表在viewWillAppear方法中写

in viewA's -(void)viewWillAppear:(BOOL)animated delegate method you can refresh the control you need... i.e. if you want to reload table that in viewWillAppear method write

[Table reloadData];
