QQ好友列表数据模型封装

QQ好友中的信息较多。假设我们单独从plist 中直接取出数据 是能够解决这个问题

可是相当复杂。以为列表中分组 。每组中还有不同信息

大致模型是 数组套数组  数组套字典

所以我们要封装数据模型

//
//  GPGroupController.h
//  02-好友分组

#import <UIKit/UIKit.h>
 
@interface GPGroupController : UIViewController

//
//  GPGroupController.m
//  02-好友分组

#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.
        NSString *path = [[NSBundle mainBundle]pathForResource:@"qq_group.plist" ofType:nil];
        NSArray * dicts =[NSArray arrayWithContentsOfFile:path];
 
        //2.
        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 that can be recreated.
}
 
/*

    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
