NSString type with index - json

Question

I have created Author class like this :
#interface Author : NSObject{
NSString *authorID;
NSString *email;
NSString *userName;
NSString *password;
NSString *jenisKelamin;
NSString *alamat;
NSString *kota;
NSString *telepon;
NSString *pekerjaan;
NSString *nama;
NSString *tanggalDaftar;
NSString *status;
NSString *lastLogin;
NSString *publishPhoto;
NSString *komentar;
NSString *balasKomentar;
NSString *newsLetter;
}
#property (nonatomic, retain)NSString *authorID;
#property (nonatomic, retain)NSString *email;
#property (nonatomic, retain)NSString *userName;
#property (nonatomic, retain)NSString *password;
#property (nonatomic, retain)NSString *jenisKelamin;
#property (nonatomic, retain)NSString *alamat;
#property (nonatomic, retain)NSString *kota;
#property (nonatomic, retain)NSString *telepon;
#property (nonatomic, retain)NSString *pekerjaan;
#property (nonatomic, retain)NSString *nama;
#property (nonatomic, retain)NSString *tanggalDaftar;
#property (nonatomic, retain)NSString *status;
#property (nonatomic, retain)NSString *lastLogin;
#property (nonatomic, retain)NSString *publishPhoto;
#property (nonatomic, retain)NSString *komentar;
#property (nonatomic, retain)NSString *balasKomentar;
#property (nonatomic, retain)NSString *newsLetter;
#end
and read json like this :
imageArray = [[NSMutableArray alloc]init];
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [[NSData alloc]initWithContentsOfURL:url];
NSError *jsonParsingError = nil;
id myJson = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&jsonParsingError];
NSDictionary *imageList;
for (int i=0; i<[myJson count]; i++) {
imageList=[myJson objectAtIndex:i];
currentImage = [ImageList alloc];
currentImage.imageID=[imageList valueForKey:#"id"];
currentImage.tanggal=[imageList valueForKey:#"tanggal"];
currentImage.judul=[imageList valueForKey:#"judul"];
currentImage.namaFile=[imageList valueForKey:#"nama_file"];
currentImage.deskripsi=[imageList valueForKey:#"deskripsi"];
currentImage.user=[imageList valueForKey:#"user"];
currentImage.status=[imageList valueForKey:#"status"];
currentImage.views=[imageList valueForKey:#"views"];
currentImage.rating=[imageList valueForKey:#"rating"];
currentImage.totalRating=[imageList valueForKey:#"total_rating"];
currentImage.totalPerating=[imageList valueForKey:#"total_perating"];
currentImage.imageThemeID=[imageList valueForKey:#"tema"];
currentImage.bayesianRating=[imageList valueForKey:#"bayesian_rating"];
currentImage.imageURL=[imageList valueForKey:#"img_url"];
NSDictionary *authorDict = [imageList objectForKey:#"author"];
currentImage.author = [[[Author alloc] init] autorelease];
currentImage.author.authorID = [authorDict valueForKey:#"id"];
currentImage.author.email = [authorDict valueForKey:#"email"];
currentImage.author.userName = [authorDict valueForKey:#"username"];
currentImage.author.password = [authorDict valueForKey:#"password"];
currentImage.author.jenisKelamin = [authorDict valueForKey:#"jenis_kelamin"];
currentImage.author.alamat = [authorDict valueForKey:#"alamat"];
currentImage.author.kota = [authorDict valueForKey:#"kota"];
currentImage.author.telepon = [authorDict valueForKey:#"telepon"];
currentImage.author.pekerjaan = [authorDict valueForKey:#"pekerjaan"];
currentImage.author.nama = [authorDict valueForKey:#"nama"];
currentImage.author.tanggalDaftar = [authorDict valueForKey:#"tanggal_daftar"];
currentImage.author.status = [authorDict valueForKey:#"status"];
currentImage.author.lastLogin = [authorDict valueForKey:#"last_login"];
[imageArray addObject:currentImage];
[currentImage release];
return self;
}
But if I try to get the value using :
jsonImage =[[JSONReader alloc]loadImageList:newURL];
ImageList *currentImage;
currentImage = [[jsonImage imageArray]objectAtIndex:0];
[jsonTheme release];
if([jsonImage.imageArray count]>0){
NSLog(#"getting image starting");
NSURL *imageURL=[NSURL URLWithString:currentImage.imageURL];
NSLog(#"image URL from array : %#", currentImage.imageURL);
NSData *imageData=[NSData dataWithContentsOfURL:imageURL];
imgTemp = [UIImage imageWithData:imageData];
self.imgImage.image = imgTemp;
NSLog(#"getting image stop");
lblDate.text = currentImage.tanggal;
lblDescription.text = currentImage.deskripsi;
lblSummary.text = currentImage.judul;
Author *currentAuthor = currentImage.author;
lblUser.text = currentAuthor.userName;
[currentImage release];
}
lblUser.text = currentTheme.author.userName; the result of lblUser is null.
when I tried to debug, the value of userName have index :
currentAuthor Author * 0x071a9a20
NSObject NSObject
authorID NSString * 0x0753e700
[0] id 0x071a4ad0
[0] id
email NSString * 0x075403a0
[0] id 0x071a58e0
userName NSString * 0x0753fef0
[0] id 0x071a5930
can you tell me how to get currentAuthor values ?

Answer 1

I think , while releasing currentImage . value of author also changed.
Please do the following changes and try it
Author *currentAuthor =[ currentImage.author copy];
