PODifficulty with accessing list of URLs in XML file
text
Body
copied!<p>I am trying to make an app that plays MP3 songs. My program flow is like this:</p> <p>I have an XML file here in my website: <a href="http://jeewanaryal.web44.net/SongsXML/songsListXML.xml" rel="nofollow">http://jeewanaryal.web44.net/SongsXML/songsListXML.xml</a>. It has song titles and the actual URL of those songs on the Internet. I have the following code for my Pop songs section:</p> <pre><code>NSString *urlString = @"http://jeewanaryal.web44.net/SongsXML/songsListXML.xml"; NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]]; NSDictionary *dict = [XMLReader dictionaryForXMLData:data error:nil]; NSArray *arrayOfSongs = [[NSArray alloc] initWithArray:[[[dict objectForKey:@"list"] objectForKey:@"songs"] objectForKey:@"song"]]; StartStopSound = [UIButton buttonWithType:UIButtonTypeRoundedRect]; StartStopSound.frame = CGRectMake(60, 360, 200, 30); [StartStopSound setTitle:@"बजाउनुहोस" forState:UIControlStateNormal]; [StartStopSound addTarget:self action:@selector(playSong) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:StartStopSound]; back = [UIButton buttonWithType:UIButtonTypeRoundedRect]; back.frame = CGRectMake(20, 320, 100, 30); [back setTitle:@"पछाडीको गीत " forState:UIControlStateNormal]; [back addTarget:self action:@selector(playSong) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:back]; next = [UIButton buttonWithType:UIButtonTypeRoundedRect]; next.frame = CGRectMake(200, 320, 100, 30); [next setTitle:@"अगाडीको गीत" forState:UIControlStateNormal]; [next addTarget:self action:@selector(playSong) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:next]; NSData *myData = [[NSData alloc] init ]; NSString *urlString1 = [[NSString alloc] init]; for (NSDictionary *fruitDict in arrayOfSongs) { UILabel *songTitle = [[UILabel alloc] initWithFrame:CGRectMake(40, 200, 300, 40)]; songTitle.text = [NSString stringWithFormat:@"%@",[[fruitDict objectForKey:@"title"] objectForKey:@"text"]]; [self.view addSubview:songTitle]; urlString1 = [NSString stringWithFormat:@"%@",[[fruitDict objectForKey:@"url"] objectForKey:@"text"]]; //NSLog(@"\n\n -- URL STRING : %@ \n\n",urlString); } myData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString1]]; player = [[AVAudioPlayer alloc] initWithData:myData error:nil]; [player play]; [player numberOfLoops]; [player currentTime]; </code></pre> <p>This works fine for a single song; that is, it only plays the last URL of my XML file. I want to make all songs to be played one by one, making a "Next" and "Previous" button on my app.</p> <p>Will you please tell me how I can implement that? I am using XMLReader.h and XMLReader.m file to parse the data from XML into my app.</p>
