ios - 我如何使用在另一个视图中解析的 XML，而不是我解析 XML 的视图？

Question

我想使用在我的主视图中解析的数据，主视图是一个导航表视图控制器，我想在一个提要的每个帖子的详细视图中使用解析的数据。我不知道我该怎么做，我需要帮助。谢谢 ：）

主视图控制器.h

#import <UIKit/UIKit.h>

@interface MasterViewController : UITableViewController <NSXMLParserDelegate>

@property NSMutableArray *posts;
@property NSMutableString *currentStr;
@property NSMutableDictionary *currentDic;

@end

主视图控制器.m

#import "MasterViewController.h"

#import "DetailViewController.h"

@interface MasterViewController () {
    NSMutableArray *_objects;

}
@end

@implementation MasterViewController
@synthesize currentDic, currentStr, posts;
- (void)awakeFromNib
{
    [super awakeFromNib];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSURL *url = [[NSURL alloc] initWithString:@"http://devlabs.es/feeds/"];
    posts = [[NSMutableArray alloc]init];
    NSXMLParser *parserFeed = [[NSXMLParser alloc] initWithContentsOfURL:url];
    parserFeed.delegate = self;
    [parserFeed parse];
}

- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {

    if ([elementName isEqualToString:@"item"]) {
        currentDic = [[NSMutableDictionary alloc]init];
        currentStr = [[NSMutableString alloc]init];
    }
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

    if ([elementName isEqualToString:@"title"]) {
        [currentDic setValue:currentStr forKey:@"titulo"];
    } if ([elementName isEqualToString:@"link"]) {
        [currentDic setValue:currentStr forKey:@"link"];
    } if ([elementName isEqualToString:@"description"]) {
        [currentDic setValue:currentStr forKey:@"description"];
    } if ([elementName isEqualToString:@"item"]) {
        [posts addObject:currentDic];
    }

    currentStr = nil;

}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    if (!currentStr) {
        currentStr = [[NSMutableString alloc]initWithString:string];
    } else {
        [currentStr appendString:string];
    }

    cell.detailTextLabel.text = [dic objectForKey:@"description"];
    return cell;

    return YES;

    }
