Accessing NSMutableData from another class

Ok I have declared the NSMutableData in the .h of class 1 as followed

NSMutableData *dataResponse;

@property (strong, nonatomic) NSMutableData *dataResponse;

in the .m of class 1 I have @synthezie dataResponse, and then I am giving it some data in a function.

I want to access dataResponse in class 2 with that data that I have assigned to it in the function.

How can I get the data from dataResponse in class 2? Any help would be great.

Create an instance of the class and use the -mutableByes method. If you still need more information, check out the class reference for NSMutableData, right here

You can use helper class for accessing array in different class. Create an NSObject file in the project. I've named it Passing Class

In your PassingClass.h

#import <Foundation/Foundation.h>

@interface PassinClass : NSObject
{
  NSMutableData *dataResponsetoPass;
}
+(PassinClass*)sharedString;


-(void)setdataResponsetoPass:(NSMutableData*)data;
-(NSMutableData*)getDataResponse;

In your PassinClass.m

#import "PassinClass.h"

@implementation PassinClass
@synthesize dataResponsetoPass;
static PassinClass*sharedString;

+(PassinClass*)sharedString
{
 if(!sharedString)
 {
    sharedString=[[PassinClass alloc]init];
  }

  return sharedString;
}


-(void)setdataResponsetoPass:(NSMutableData*)data
{
  dataResponsetoPass=data;
}
-(NSMutableData*)getDataResponse;
{
   return dataResponsetoPass;
}

In your class1.h create instance of this helper class.

#import "PassinClass.h"
{
  PassinClass*pClass;
}

In your class1.m, set the data using 

pClass=[PassinClass sharedString];
[pClass setdataResponsetoPass:Your Data];

In your class2.m get the data using

pClass=[PassinClass sharedString];
[pClass getDataResponse];

NSLog the [pClass getDataResponse ] to check, if everything went well you should be able to pass the response data from class 1 to class 2.
