NSMutable Array from One Class to Another Class in iPhone

问题

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...

回答1:

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.

回答2:

in current class

#import "SecondViewController"

---

 SecondViewController *NextViewController = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

        NextViewController.nextClasssArray = thisClassarray;

in second class .h

@property(nonatomic,retain) NSMutableArray *nextClasssArray;

in second class .m

@synthesize nextClasssArray;
