Answer 1

-(NSString *)downloadXML:(NSString *)path newFileName:(NSString *)newFileName { 

    //NSLog(@"\nENTRATO NEL METODO DI DOWNLOAD"); 
    NSURL *URL = [NSURL URLWithString:[path stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]]; 
    NSData *xmlData = [NSData dataWithContentsOfURL:URL]; 
    if(xmlData == nil) { 
     // Error - handle appropriately 
    } 
    NSString *applicationDocumentsDir=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]; 
    NSString *storePath=[applicationDocumentsDir stringByAppendingPathComponent:newFileName]; 
    [xmlData writeToFile:storePath atomically:TRUE]; 

    //NSLog(@"\nFINITO IL METODO DI DOWNLOAD"); 
    return storePath; 

}
