Expanding and Collapsing table view cells in ios

Find a great code for expanding and collapsing table view on apple developer webiste. This is the link:
https://developer.apple.com/library/ios/samplecode/TableViewUpdates/Introduction/Intro.html


"TableViewUpdates" demonstrates how you can use animated updates to open and close sections of a table view for viewing, where each section represents a play, and each row contains a quotation from the play. It also uses gesture recognizers to respond to user input: * A UITapGestureRecognizer to allow tapping on the section headers to expand the section; * A UIPinchGestureRecognizer to allow dynamic changes to the height of table view rows; and * A UILongPressGestureRecognizer to allow press-and-hold on table view cells to initiate an email of the quotation.

What is NSDictionary?

If you are parsing xml data on your iOS program, please keep in mind that the code is slightly different when read xml file local from when you read it from a server.

Parsing Local XML file: ( xmlparser.m )

-(id) loadXMLByURL:(NSString *)urlString

{

   

   

    NSData *xmlData = [NSData dataWithContentsOfFile:urlString];

    NSXMLParser  *parser = [[NSXMLParser alloc] initWithData:xmlData];

    parser.delegate = self;

    [parser parse];

    return self;

   

}

Parsing  XML file from Server: ( xmlparser.m )

-(id) loadXMLByURL:(NSString *)urlString

{    

   

    NSData *xmlData = [NSData dataWithContentsOfFile:urlString];

    NSXMLParser  *parser = [[NSXMLParser alloc] initWithData:xmlData];

   NSURL *url = [NSURL URLWithString:urlString];

    NSXMLParser parser = [[NSXMLParser alloc]initWithContentsOfURL: url];

    parser.delegate = self;

    [parser parse];

    return self;

   

}
