iPhone中从一个类到另一个类的NSMutable数组

问题描述

我在FirstViewController类中有一个NSMutable数组，我想将该数组传递给SecondViewController类。我想在SecondViewController类中使用它。我正在使用ARC在Xcode 4.2.1中这样做...我怎么能......？设置属性时我想要使用的属性是什么...（或者）使用Appdelegate文件解释我...

解决方案

有两种方法可以做到这一点。

1：在appdelegate中为NSMutableArray创建一个属性，在FirstViewController中设置数组的值并在SecondViewController中检索值。

2：在SecondViewController中为NSMutableArray创建一个属性，并为FirstViewController调用此属性，但调用SecondViewController的对象，并通过FirstViewController的secondViewController对象引用调用该属性。 p>

I have an NSMutable Array in FirstViewController class, I want to Pass that array to SecondViewController class. And I want to use that in SecondViewController class. I am doing this in Xcode 4.2.1 with ARC... How can I...? and what are the attributes i want to use when setting property... (OR) Explain me using Appdelegate files also...

解决方案

There are two ways to do this.

1: Make a property for NSMutableArray in appdelegate, set the value for array in FirstViewController and retrieve value in SecondViewController.

2: Make a property for NSMutableArray in SecondViewController, and call this property for FirstViewController but making the object of SecondViewController, and calling the property via object reference of secondViewController from FirstViewController.
