@interface ViewController ()
@property(nonatomic,retain)NSMutableArray *mydata;
@end

@implementation ViewController

#pragma mark -生命周期方法
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    UITableView *tableview=[[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStyleGrouped];
    tableview.dataSource=self;
    tableview.delegate=self;
    [self.view addSubview:tableview];
    [tableview release];
    self.mydata=[NSMutableArray array];
    [self InitData1];
}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(void)viewDidUnload{
    [super viewDidUnload];
    self.mydata=nil;
}

- (void)dealloc
{
    self.mydata=nil;
    [super dealloc];
}
//数据类－－》数组－－（包含数组）－－（每一个数组中只包含多个字典（并且每个字典只有一个key--value)

#pragma mark -初始化数据

-(void)InitData1{
    //最外面的数组
    for (int i=0; i<2; i++) {
        NSMutableArray *arr1=[NSMutableArray array];
        for (int j=0; j<3; j++) {
            NSString *key=[NSString stringWithFormat:@"itcast-->%zi",j];
            NSDictionary *dic=@{key:@(i)};
            [arr1 addObject:dic];
            
        }
        [self.mydata addObject:arr1];
    }
    
}

第一种是字典

//一般数据和控件没有太大直接关系
#pragma mark -uitableview 代理方法
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return self.mydata.count;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
   NSArray *sectionq= self.mydata[section];
    return sectionq.count;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *cellIndetify=@"cell";
    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:cellIndetify];
    if(cell==nil){
        cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIndetify];
        
    }
    NSArray *section=self.mydata[indexPath.section];
    NSDictionary *row=section[indexPath.row];
   
    cell.textLabel.text=row.allKeys[0] ;
    cell.detailTextLabel.text=[NSString stringWithFormat:@"%zi",[row.allValues[0] intValue]];
    return  cell;
}

@end

第二种模型

#import <Foundation/Foundation.h>

@interface Person : NSObject
@property(nonatomic,copy)NSString *name;
@property(nonatomic,copy)NSString *dec;
@end

        }
        [self.mydata addObject:arr1];
    }
    
}


//一般数据和控件没有太大直接关系

    }

    cell.textLabel.text=row.name;

    return cell;
