往NSMuArray和NSMutableDictionary填充数据

三种方法，相同效果；

NSMutableDictionary *parDic = [[NSMutableDictionary
alloc] init];
[parDic setValue:@"616"
forKey:@"id"];
&
[parDic setObject:@"616"
forKey:@"activity_id"];
&
parDic = @{@"activity_id":@"616"};

数组
NSArray *array = [[NSArray alloc] initWithObjects:@"One",@"Two",@"Three",@"Four",nil];

array =
@[@"65465",@"54556456",@"1221"];
可变数组除了声明时可以直接添加多个，后面只能一个一个的添加；
NSMutableArray *arr = [[NSMutableArray
alloc] init];
[arr addObject:@"652626"];
