如何在加载下一个视图之前执行UIButton操作 [英] How to perform UIButton action before loading next view

问题描述

我有一个视图，用户在其中输入3个字符串字段.在按钮上按下，字段将存储在数组中.该按钮还可以更改视图.

I have a view where a user enters 3 sting fields. On the button press the fields are stored in an array. The button also changes the view.

我遇到的问题是，当我从另一个视图的数组中获取字符串时.返回的值是已输入的先前值.

The problem im having is when I get the strings from the array in the other view. The values that are being returned are the pervious values that have been entered.

我添加了一些行来记录正在执行的操作以及从数组中执行的操作.从日志中，我可以看到在设置数组之前已调用了该数组.

I have added some lines to log what is going in and what is come out of the arrays. From the log I can see that the array is being called before it is set.

在更改视图之前，如何获取按钮以运行其操作?

How to I get the button to run its action before it changes the view?

这是我的日志:
