将对象传递给UIViewController类 [英] Passing an Object to UIViewController Class

问题描述

我正在开发一个应用程序，在该应用程序中我想将一个类的对象从一个UIViewController传递给另一个，我该怎么做?

I am working on an app in which I want to pass an object of a class from one UIViewController to another, How I can do that?

推荐答案

在初始化新的View Controller时，请定义一个变量，如下所示:

when you initialize your new View Controller define a variable as follows:

 MyClass *myClass = [[MyClass alloc] init];
 myClass.username = @"Rahul Kushwaha"; 
 // assume a property called username is defined in MyClass of a NSString type.

 NextViewController *controller = [NextViewController alloc];
 controller.myClassObject = myClass ;
 [self.navigationController pushViewController:controller animated:YES];

别忘了您必须在NextViewController中定义类型为(MyClass)的对象.

Don't forget you have to define an object of type (MyClass) in NextViewController.

样品

NextViewController. h

NextViewController.h

#import "MyClass.h"

@interface NextViewController
{
  MyClass *myClassObject;
}

@property (nonatomic,retain) MyClass *myClassObject;

---

NextViewController. m

---

NextViewController.m

@synthesize myClassObject;
