Take one NSTimer at time of launch splash screen.

Put your splash screen in sleep mode.

Store parse data in array.

In the below method of parser 

-(void)parserDidEndDocument:(NSXMLParser *)parser
{
if([array count]>0){
//load view whatever you want and display fresh data
}else{
//Alert msg Data not available or display old data if available in database.
}
}

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
{

}

Do this in AppDelegate API

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

Make a webservice call in this method. It is the first method that is invoked after main()
