iphone - How to wait for NSXMLParser to complete in iOS -

i want wait nsxmlparser process complete , continue other processes. use nsxmlparser parse xml data.

this code:

 - (void)parser:(nsxmlparser *)parser didstartelement:(nsstring *)elementname namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qualifiedname attributes:(nsdictionary *)attributedict {    nslog(@"did start element");    if ( [elementname isequaltostring:@"filename"])    {        xml_field = filename_cloud2;        nslog(@"found rootelement");        return;    }    else if ( [elementname isequaltostring:@"uploadtime"])    {        nslog(@"found rootelement");        xml_field = uploadtime2;        return;    }  } 

didendelement():

 - (void)parser:(nsxmlparser *)parser didendelement:(nsstring *)elementname namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qname {    nslog(@"did end element");    if ([elementname isequaltostring:@"filename"])    {       nslog(@"rootelement end");    }    xml_field = unimportant2; } 

foudcharaters():

- (void)parser:(nsxmlparser *)parser foundcharacters:(nsstring *)string {    if (xml_field == filename_cloud2)    {       nslog(@"value %@",string);       [filecompletedarray insertobject:string atindex:0];    }    else if (xml_field == uploadtime2)    {       nslog(@"value %@",string);       [uploadtimearray insertobject:string atindex:0];    } } 

above code used data nsxmlparser app needs wait parse xml process complete. can use dispatch () ?

nsxmlparser works synchronous. when parse method returns parsing finished (or has failed error). there no need "wait" complete.
