Question

I want to load data from Web service while showing the Splash Screen. In the initial Screen I need to display those data. How can I do this ? From where I need to call the webservice?

Answer 1

you must call webservice in your Appdelegate and create globle NSmutableArray and use this array in your app
with xml parsiong

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  

  NSString *path = [NSString stringWithFormat:your url path];

    NSLog(@"path= %@",path);

    [self parseXMLFileAtURL:path];

}
-(void)parseXMLFileAtURL:(NSString*)URL
{

    NSURL *url = [NSURL URLWithString:URL];
    RssParser = [[NSXMLParser alloc] initWithContentsOfURL:url];
    [RssParser setDelegate:self];
    [RssParser setShouldProcessNamespaces:NO];
    [RssParser setShouldReportNamespacePrefixes:NO];
    [RssParser setShouldResolveExternalEntities:NO];
    [RssParser parse];
}

-(void)parserDidStartDocument:(NSXMLParser *)parser
{   

}

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{


}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{

}


- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{

}
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError 
{
}

-(void)parserDidEndDocument:(NSXMLParser *)parser
{

}
