   @interface PlistReader : NSObject
   {
       NSDictionary *temp;
   }
   @property (nonatomic,retain) NSDictionary *temp;
   
   -(int)LengthOfPList;
   -(id)GetTheObjectById:(NSString*)ObjId;
   -(void)initWithFileName:(NSString*)fileName;
   - (id)getCountryInfoById:(int)id;
   @end

   Implementation file

   #import "PlistReader.h"
   
   @implementation PlistReader
   @synthesize temp;
   
   -(id)init
   {
       if(self =[super init])
       {
   
       }
       return self;
   }
   -(void)initWithFileName:(NSString*)fileName
   {
       // Data.plist code
       // get paths from root direcory
   
       NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
       // get documents path
       NSString *documentsPath = [paths objectAtIndex:0];
       // get the path to our Data/plist file
       NSString *plistPath = [documentsPath stringByAppendingPathComponent:[fileName stringByAppendingString:@"plist"]];
   
       // check to see if Data.plist exists in documents
       if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath])
       {
           // if not in documents, get property list from main bundle
           plistPath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"plist"];
       }
   
       // read property list into memory as an NSData object
       NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];
       NSString *errorDesc = nil;
       NSPropertyListFormat format;
       // convert static property liost into dictionary object
       temp =(NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];
       if (!temp)
       {
           NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
       }
       // assign values
   
   }
   
   -(int)LengthOfPList
   {
       return temp.count;
   }
   -(id)GetTheObjectById:(NSString*)ObjId
   {
   
      return [temp objectForKey:ObjId];
   
   }
   -(id)getCountryInfoById:(int)objId
   {
   
       NSString *objsId = [NSString stringWithFormat:@"%d",objId];
       NSDictionary *CDirectory = (NSDictionary*) [self GetTheObjectById:objsId];
       int count = CDirectory.count;
       if(count>0)
       {
           CountryClass *objCountry = [[CountryClass alloc] init];
           objCountry.Name= [CDirectory objectForKey:@"Name"];
           objCountry.LocationX =[[CDirectory objectForKey:@"PositionX"] intValue];
           objCountry.LocationY = [[CDirectory objectForKey:@"PositionY"] intValue];
           objCountry.ImageUrl = [CDirectory objectForKey:@"ImageUrl"];
           objCountry.AnthemUrl =[CDirectory objectForKey:@"AnthemUrl"];
           objCountry.ShortDetail =[CDirectory objectForKey:@"short Info"];
           objCountry.completeDetails = [CDirectory objectForKey:@"Details"];
           id ObjCountryInfo= objCountry;
           [objCountry release];
           return ObjCountryInfo;
       }
       return NULL;
   }
   
   -(void)dealloc
   {
       NSLog(@"dealloc plist");
       [temp release];
       [super dealloc];
   }
   
   @end

   and the other is country class which has following code
   

   //
       //  CountryClass.h
       //  NationalAntemsAndFlags
       //
       //  Created by mac on 12/17/11.
       //  Copyright (c) 2011 __MyCompanyName__. All rights reserved.
       //
   
       #import <Foundation/Foundation.h>
   
       @interface CountryClass : NSObject
       {
           NSString *Name ;
           NSString *ImageUrl;
           NSString *AnthemUrl;
           NSString *ShortDetail;
           NSString *completeDetails;
           int LocationX ;
           int LocationY ;
   
       }
       @property (nonatomic,retain) IBOutlet NSString *Name;
       @property (nonatomic,retain) IBOutlet NSString *ImageUrl;
       @property (nonatomic,retain) IBOutlet NSString *AnthemUrl;
       @property (nonatomic,retain) IBOutlet NSString *ShortDetail;
       @property (nonatomic,retain) IBOutlet NSString *completeDetails;
       @property (nonatomic) IBOutlet int LocationY;
       @property (nonatomic) IBOutlet int LocationX;
   
       @end

   implementation file

   //
       //  CountryClass.m
       //  NationalAntemsAndFlags
       //
       //  Created by mac on 12/17/11.
       //  Copyright (c) 2011 __MyCompanyName__. All rights reserved.
       //
   
       #import "CountryClass.h"
   
       @implementation CountryClass
   
       @synthesize Name,ImageUrl,AnthemUrl,ShortDetail,completeDetails,LocationX,LocationY;
   
       @end

   so i called this in my scene like this
   

   -(void)LoadData:(int)countryId
       {
           CId = countryId;
           PlistReader *pList =[[PlistReader alloc]init];
           [pList initWithFileName:@"CountryDetails"];   
   
           CountryClass *objcountry = (CountryClass*) [pList getCountryInfoById:countryId];
   
           NSString *tempLongDetails = objcountry.completeDetails;
           NSString *tempShortDetails = objcountry.ShortDetail;
           NSString *fileName =  objcountry.ImageUrl ;
           CCSprite *flag ;
   
           NSString * fullPath = [[NSBundle mainBundle] pathForResource: [fileName stringByDeletingPathExtension]
                                                                    ofType: [fileName pathExtension]
                                                                  inDirectory: @"CountryFlags"];
   
           NSLog(fullPath);
           if (fullPath)
           {
              UIImage  *theImage = [UIImage imageWithContentsOfFile: fullPath];
              if (theImage)
              {
                   flag = [CCSprite spriteWithCGImage: [theImage CGImage] key: fileName];
                  // flag = [CCSprite spriteWithFile:fileName];
                   flag.position = ccp(200, 265);
                  flag.scale = .255;
              }
           }
   
           TextViewTopFlagData = [[UITextView alloc]init];
           TextViewTopFlagData.text = tempShortDetails;
           TextViewTopFlagData.frame = CGRectMake(260,17, 105, 75);
           TextViewTopFlagData.backgroundColor = [UIColor clearColor];
           [TextViewTopFlagData setEditable:NO];
   
           TextViewDownFlagData = [[UITextView alloc]init];
           TextViewDownFlagData.text = tempLongDetails;
           TextViewDownFlagData.frame = CGRectMake(22,240, 242, 61);
           TextViewDownFlagData.backgroundColor = [UIColor clearColor];
           [TextViewDownFlagData setEditable:NO];
           [[[CCDirector sharedDirector]openGLView]addSubview:TextViewTopFlagData];
           [[[CCDirector sharedDirector]openGLView]addSubview:TextViewDownFlagData];
           [self addChild:flag];
   
       }
   
       @end

   but at the end of the function objcountry will be empty or out of reference can any one explain me that why this is happaning
