将viewControllers视图添加到另一个viewController [英] adding a viewControllers view to another viewController

问题描述

我对iPhone开发完全陌生.我有两个ViewControllers

I am completely new to iPhone development. I have two ViewControllers

1. ViewControllerA
2. ViewControllerB

ViewControllerA是第一个，并随应用程序一起启动.

ViewControllerA is the first one and launches with the app.

我现在有另一个ViewControllerB，我想在应用程序启动时将ViewControllerB的视图作为子视图添加到ViewControllerA的视图中.

I have another ViewControllerB now I want to add view of ViewControllerB as subview to ViewControllerA's view when application launches.

推荐答案

尝试一下

ViewControllerB *vcb = [[ViewControllerB alloc] init];

[self.view addSubview:vcb.view];
