从 UIView ios 推送视图控制器 [英] push a view controller from a UIView ios

问题描述

我有一个基于导航的应用程序.单击第一个屏幕中导航栏上的按钮，我可以按如下方式推送另一个视图控制器:

I have a navigation based application.On click of a button on the navigation bar in the first screen , I am able to push another view controller as follows :

 -(void) buttonClicked:(id)sender
{

    UIViewController*  mv = [[SecondViewController alloc] init];

    [[self navigationController] pushViewController:mv animated:YES];  

}

现在我有一个 UIView(单独的 .h 和 .m 文件)作为第一个屏幕的一部分.单击 UIView 中的按钮，我想推送 SecondViewController.我尝试了以下方法:

Now i have a UIView(separate .h and .m files) as part of the first screen. On click of a button in the UIView, i want to push the SecondViewController. I have tried the following :

 UIViewController*  mv = [[SecondViewController alloc] init];
 UIViewController * home=[[FirstViewController alloc]init];
 [[home navigationController] pushViewController:mv animated:YES];

它不起作用！！请帮忙

推荐答案

你可以使用这个.它对我来说非常有效:-

You Can use this. It Works very well for me:-

首先在 UIView 类中创建 AppDelegate 对象并初始化.然后在 Appdelegate.h 中创建 Navigationcontroller 对象:-

Firstly Create Object of AppDelegate in UIView Class and initialize it. Then create Navigationcontroller object in Appdelegate.h :-

@property(strong,nonatomic) UINavigationController *navControl;

在你的 UIView 类中实现你想要推送的代码:-

In your UIView Class implement this code where you want to push :-

ViewController *objview = [[ViewController alloc]init]; [appDelegate.navControl pushViewController:objview animated:YES];
