QQ Friends List Data Model encapsulation

QQ Friends in more information, if we separate from the plist directly remove the data is to solve the problem

But it's quite complicated to think of groups in the list, with different information in each group.

The approximate model is a set of arrays of array array arrays dictionary

So we're going to encapsulate the data model

  gpgroupcontroller.h//  02-Friends Group//#import <UIKit/UIKit.h> @interface Gpgroupcontroller: Uiviewcontroller@end

gpgroupcontroller.m//02-Friends Group//#import "GPGroupController.h" #import "GPGroup.h" #import "Nsarray+localprint.h" @ Interface Gpgroupcontroller () @property (Nonatomic,strong) Nsarray *groups; @end @implementation gpgroupcontroller-(        Nsarray *) groups{if (_groups = = nil) {//1.

Nsmutablearray *OBJS = [Nsmutablearray array];            For (Nsdictionary *dic in dicts) {Gpgroup *group = [Gpgroup groupwthdict:dic];        [Objs Addobject:group];        }//3.    _groups = OBJS; } return _groups;}    -(void) viewdidload {[Super viewdidload];    NSLog (@ "%@", self.groups); Do any additional setup after loading the view.}    -(void) didreceivememorywarning {[Super didreceivememorywarning]; Dispose of any resources the can be recreated.} /* #pragma mark-navigation//in a storyboard-based application, you'll often want to do a little preparation before navigation-(void) preparefor Segue: (uistoryboardsegue *) Segue sender: (ID) Sender {//Get the new view controller using [Segue Destinationviewcontrol    Ler].
