我试图获取将视图转换到第二页的按钮，以同时将文本分配给第三页上的主题行。我知道如何在主题中获取文本，但我不知道如何获取文本。

我很抱歉不清楚这我是初学者。

没有看到一些代码很难回答，但我会试一试。

从软件设计的角度来看，您的“第三页”不要依赖第一页或第二页，这一点很重要。因此，当您推送第二页时，您向它提供了第一页所需的信息。例如：

第一页代码（伪代码，不在 Mac 上）：

SecondPageController *secondPage = [[SecondPageController alloc]init];
secondPage.subjectLine = @"Flat Tire";
[self PushViewController:secondPage];

然后在您的第二页上，当移动到第三页时：

ThirdPageController *thirdPage = [[ThirdPageController alloc] init];
thirdPage.subjectLine = self.subjectLine;
[self PushViewController:thirdPage];

这样每个控制器都知道它需要知道什么来完成它的工作。第三个控制器不依赖，也不需要知道任何关于第一个或第二个控制器的信息，只知道创建它的任何东西，初始化它的subjectLine属性（加上其他需要的东西）。
