チュートリアルに従っていますがうまくいきましたが、2つのRSSフィードを解析したい場合は、それぞれの配列に保存する代わりに1つの配列を上書きするように見えます。2つのRSSフィードをアプリデリゲートで解析する
これは私の代表である：次いで、2を解析し
@synthesize pics;
@synthesize books;
NSURL *url2 = [[NSURL alloc] initWithString:@"myRSSFEED1"];
NSXMLParser *xmlParser1 = [[NSXMLParser alloc] initWithContentsOfURL:url2];
//Initialize the delegate.
XMLParser1 *parser1 = [[XMLParser1 alloc] initXMLParser];
//Set delegate
[xmlParser1 setDelegate:parser1];
//Start parsing the XML file.
BOOL successs = [xmlParser1 parse];
if(successs)
NSLog(@"No Errors");
else
NSLog(@"Error Error Error!!!");
//VIDS
NSURL *url = [[NSURL alloc] initWithString:@"MYRSSFEED2"];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
//Initialize the delegate.
XMLParser *parser = [[XMLParser alloc] initXMLParser];
//Set delegate
[xmlParser setDelegate:parser];
//Start parsing the XML file.
BOOL success = [xmlParser parse];
if(success)
NSLog(@"No Errors");
else
NSLog(@"Error Error Error!!!");
アレイにそれを割り当てます。
そして、私のXMLParser & XMLParser1
に保存された私は、上書きからそれを停止する方法を見つけ出すことはできません。私はどこのポイントにブレークポイントを置くことをお勧めし、この上の任意のヘルプは素晴らしいだろう

そして、私のXMLParser.m

//Extract the attribute here.
aBook.bookID = [[attributeDict objectForKey:@"id"] integerValue];
NSLog(@"Reading id value :%i", aBook.bookID);
}
NSLog(@"Processing Element: %@", elementName);
}

}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName

カントーヘルプは？ –
2番目のフィードを処理する部分をデリゲートに表示すると便利です。 – sosborn
@Chris Greggそれだけの本の配列に保存するようだ写真 –
