Make db layer apart from code

Some times we need to do a big project in xcode
we should try to make datacotroller deferent than our codes

make a data controller


@interface DataController : NSObject {
NSMutableArray *list;
NSMutableArray *namelist;
NSMutableArray *mobiles;
NSMutableData *tdata;
NSMutableArray *ids;
NSMutableArray *sgns;
NSMutableArray *Emails;
NSMutableArray *Fexs;
NSMutableArray *Birthdays;
NSMutableArray *Annidays;
NSString *searchfilter;
}

- (unsigned)countOfList;
-(NSMutableArray *) GetList;
-(NSMutableArray *) GetIds;
-(NSMutableArray *) Getsgns;
-(NSMutableArray *) Getmobiles;
-(NSMutableArray *) GetEmails;
-(NSMutableArray *) GetFexs;
-(NSMutableArray *) GetBirthdays;
-(NSMutableArray *) GetAnniversarydays;
-(void) SetFilter:(NSString *)search;
-(NSString *)searchfilter;
- (void)createDemoData:(NSString *)search;
@end

and implement it as data layer



#import "DataController.h"
#import "DataSet.h"
#import "WebServiceHelper.h"

@interface DataController ()
