Hi. I use an instance of NSXMLParser. I store found chars in NSMutableStrings that are stored in an NSMutableDictionary and these Dicts are then added to an NSMutableArray.
When I test this everything seems normal: I count 1 array, x dictionnaries and x strings.
In a detailview controller file I want to show my parsed results. I call the class where everthing is stored but I get (null) returned.
This is what I do (wrong):
XMLParser.h
@interface XMLParser : NSObject {
NSMutableArray *array;
NSMUtableDictionary *dictionary;
NSSMutabletring *element;
}
@property (nonatomic, retain) NSMutableArray *array;
@property (nonatomic, retain) NSMutableDictionary *dictionary;
@property (nonatomic, retain) NSMutableString *element;
XMLParser.m
@synthesize array, dictionary, element;
//parsing goes on here & works fine
//so 'element' is filled with content and stored in a dict in an array
//and released at the end of the file
In my controller file I do this:
controller.h
@class XMLParser;
@interface controller : UIViewController {
XMLParser *aXMLParser;
}
@property (nonatomic, retain) XMLParser *aXMLParser;
controller.m
#import "XMLParser.h"
@synthesize aXMLParser;
- (void)viewDidLoad {
NSLog(@"test array: %@", aXMLParser.array);
NSLog(@"test dict: %@", aXMLParser.dictionary);
NSLog(@"test element: %@", aXMLParser.element);
}
When I test the value of my array, a dict or an element in the XMLParser.h file I get my result. What am I doing wrong so I can't call my results in my controller file? Any help is welcome, because I'm pretty stuck right now :/
