This document provides an overview of iOS programming using Objective C and iOS. It introduces Ankit Desai and his background and research interests. It then provides code snippets for creating a GUI with a table view for video playback, parsing an XML file to load data into the table, and implementing the necessary delegate methods and orientations support. The code shows how to parse the XML data, load it into an array, and display it in the table view cells.

1. iOS Programming
Objective C + iOS

2. Profile
Ankit Desai
 Ph.D. Scholar, IET, Ahmedabad University
 Education: M. Tech. CE, B.E. I. T.
 Experience: 7.5 Years (Academic and Research)
 Research Interest: IoT, Big Data Analytics,
Machine Learning, Data Mining.

3. Create GUI for Video
Playback
Drag and Drop TableView on xib , Link DataSource and Delegate with
ViewController.

4. Drag Some xml file to
Project

5. ViewController.m
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
<NSXMLParserDelegate,UITableViewDataSource,UITableViewDelegate>
{
NSMutableArray *arrdata;
NSMutableDictionary *dictdata;
NSString *strcontent;
}
@end

6. ViewDidLoad Method
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSData *strdata=[[NSData alloc]initWithContentsOfFile:[[NSBundle
mainBundle]pathForResource:@"my" ofType:@"xml"]];
NSXMLParser *parsar=[[NSXMLParser alloc]initWithData:strdata];
parsar.delegate=self;
[parsar parse];
}

7. Delegate Method 1 & 2
- (void)parserDidStartDocument:(NSXMLParser *)parser
{
arrdata =[[NSMutableArray alloc]init];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString
*)elementName namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
if([elementName isEqual:@"student"])
{
dictdata=[[NSMutableDictionary alloc]init];
}
}

8. Delegate Method 3, 4 & 5
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(@"%@",[arrdata description]);
}

9. Orientation Support
-
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfac
eOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation !=
UIInterfaceOrientationPortraitUpsideDown);
}

10. Make sure about
orientations under project’s
properties

11. Load Table Data
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [arrdata count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[[UITableViewCell
alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
NSLog(@"%@",[arrdata description]);
cell.textLabel.text=[[arrdata
objectAtIndex:indexPath.row]objectForKey:@"name" ];
return cell;
}
