Accessing NSMutableData from another class

Question

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.

Answer 1

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.

Answer 2

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
