ios中怎样把数组加到数组里面

// NSMutableArray *mutArr = [NSMutableArray array];
// [mutArr addObject:dict];
//
// NSMutableDictionary *dictbbb =[[NSMutableDictionary alloc]init];
// [dictbbb setObject:mutArr forKey:@"person"];
// NSLog(@"dictbbb is %@",dictbbb);
//
//
// NSData *dictData1 = [NSJSONSerialization dataWithJSONObject:dictbbb options:NSJSONWritingPrettyPrinted error:nil];
// NSString *jsonString1= [[NSString alloc]initWithData:dictData1 encoding:NSUTF8StringEncoding];
//
// NSLog(@"jsonbbbb str is %@",jsonString1);
//
//
//
// NSData* xmlData = [jsonString1 dataUsingEncoding:NSUTF8StringEncoding];
// NSMutableArray *mutDict1 = [NSJSONSerialization JSONObjectWithData:xmlData options:(NSJSONReadingMutableLeaves) error:nil];
//
// NSLog(@"mutdicr1 是%@",mutDict1);
NSDictionary *dictaaaaa = [mutDict1 objectForKey:@"name" ];

// NSString *name2 = [perDict objectForKey:@"name"];
// NSLog(@"姓名是：%@",name2);
