下面的步驟添加代碼

Add all the classes,except detailtableviewcontroller and Rootviewcontroller from the code you downloaded from the link. Then add #import "MWFeedParser.h" in your.h file where you are parsing .Then add // Parsing 
MWFeedParser *feedParser; 
NSMutableArray *parsedItems; 

// Displaying 
NSArray *itemsToDisplay; 
NSDateFormatter *formatter;and /***mwfeed (*/ 
@property (nonatomic, retain) NSArray *itemsToDisplay;  
/*------------*/ 
Then in .m add the codeformatter = [[NSDateFormatter alloc] init]; 
[formatter setDateStyle:NSDateFormatterShortStyle]; 
[formatter setTimeStyle:NSDateFormatterShortStyle]; 
parsedItems = [[NSMutableArray alloc] init]; 
self.itemsToDisplay = [NSArray array]; 
// Parse 
NSURL *feedURL = [NSURL URLWithString:@"http://feeds.feedburner.com/yummydietfood?format=xml"]; 
feedParser = [[MWFeedParser alloc] initWithFeedURL:feedURL]; 
feedParser.delegate = self; 
feedParser.feedParseType = ParseTypeFull; // Parse feed info and all items 
feedParser.connectionType = ConnectionTypeAsynchronously; 
[feedParser parse]; 
#pragma mark - 
#pragma mark MWFeedParserDelegate 

- (void)feedParserDidStart:(MWFeedParser *)parser { 
    //[UIApplication sharedApplication].networkActivityIndicatorVisible=YES; 
    NSLog(@"Started Parsing: %@", parser.url); 
} 

- (void)feedParser:(MWFeedParser *)parser didParseFeedInfo:(MWFeedInfo *)info { 
    NSLog(@"Parsed Feed Info: 「%@」", info.title); 
    //self.title = info.title; 
} 

- (void)feedParser:(MWFeedParser *)parser didParseFeedItem:(MWFeedItem *)item { 
    NSLog(@"Parsed Feed Item: 「%@」", item.title); 
    if (item) [parsedItems addObject:item]; 
} 

- (void)feedParserDidFinish:(MWFeedParser *)parser { 
    NSLog(@"Finished Parsing%@", (parser.stopped ? @" (Stopped)" : @"")); 
    self.itemsToDisplay = [parsedItems sortedArrayUsingDescriptors: 
          [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"date" 
                       ascending:NO] autorelease]]]; 

    [UIApplication sharedApplication].networkActivityIndicatorVisible=YES; 

    //[self performSelector:@selector(loadData)]; 
    [self performSelector:@selector(loadDataWithOperation)]; 

} 

- (void)feedParser:(MWFeedParser *)parser didFailWithError:(NSError *)error { 
    NSLog(@"Finished Parsing With Error: %@", error); 

    UIAlertView *erroralert = [[UIAlertView alloc]initWithTitle:@"Error!" message:@"Problem connecting server, try again in few minutes" delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil]; 
    [erroralert show]; 
    [erroralert release]; 
    self.itemsToDisplay = [NSArray array]; 
    [parsedItems removeAllObjects]; 
    self.tbl.userInteractionEnabled = YES; 

    [self.tbl reloadData]; 
} 

，並在您需要通過調用該行代碼

if (item) { 
    NSString *itemTitle = item.title ? [item.title stringByConvertingHTMLToPlainText] : @"[No Title]"; 


    lbl.text = itemTitle; 
} 
else { 
    lbl.text=@"No Title"; 
}

檢查您的編碼。底線是你可能得到的UTF-8的HTML和ISO-8859-1的字符串
