UIview不会加载viewdidappear [英] UIview doesn't load with viewdidappear

问题描述

我有一个带视图的tableview项目，在此视图中执行的所有操作均由"viewdidappear"方法控制.

I have a tableview project which has a view, everything that I do in this view is controlled by "viewdidappear" method.

我添加了一个新的UIview，其中包含"lines.h"和"lines.m"文件.

I added a new UIview which has "lines.h" and "lines.m" files.

我使用此视图来绘制一些线条并创造上帝.

I use this view to draw some lines and works god.

此额外视图位于滚动视图中，因为要长时间显示在iPhone屏幕上.

This extra view is located in to a scroll view because is to long to display in to iPhones screen.

问题在于viewdidappear不会重新加载uiview数据，而只能与viewdidload一起使用.

The problem is that viewdidappear doesn't reload the uiview data, it only works with viewdidload.

我必须关闭应用程序并重新打开它才能重新加载数据.

I have to close the application and reopen it to get my data reload.

推荐答案

首先，尝试在 viewDidAppear 方法的末尾添加以下行:

First, try adding this line at the end of viewDidAppear method:

[self.view setNeedsDisplay];

或者:

[_linesView setNeedsDisplay];

第二，提供更多信息.将代码发布到 viewDidLoad 和 viewDidAppear 中.

Second, Provide some more information. Post the code in viewDidLoad and viewDidAppear.
