我有 3 个带有整数（枚举）的数组：

static int *openEnv[] = {INGMenuItemLogon,INGMenuItemSpace,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};
static int *closedEnv[] = {INGMenuItemLogoff,INGMenuItemSpace,INGMenuItemOverview,INGMenuItemAccounts,INGMenuItemTransfer,INGMenuItemAnalyse,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};
int *currentEnv[];

如果用户点击一个按钮，我希望将currentEnv其更改为openEnv或closedEnv

- (void) tap
{
    if( closed ) currentEnv = closedEnv;
    else currentEnv = openEnv;
}

但这会产生构建错误。 openEnv并且closedEnv有 2 种不同的尺寸，我应该怎么做才能复制它？我该怎么做才能引用或复制到它的静态数组？

尝试这个：

static int *openEnv[] = {INGMenuItemLogon,INGMenuItemSpace,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};
static int *closedEnv[] = {INGMenuItemLogoff,INGMenuItemSpace,INGMenuItemOverview,INGMenuItemAccounts,INGMenuItemTransfer,INGMenuItemAnalyse,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};
//int *currentEnv[];
int **currentEnv;

- (void) tap
   {
     if( closed ) 
        currentEnv = closedEnv;
     else 
        currentEnv = openEnv;
   }

只需使用：int ** currentEnv = <the array>

您已经声明了指向 int的指针数组。正确的是

static int openEnv[] = {INGMenuItemLogon,INGMenuItemSpace,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};
static int closedEnv[] = {INGMenuItemLogoff,INGMenuItemSpace,INGMenuItemOverview,INGMenuItemAccounts,INGMenuItemTransfer,INGMenuItemAnalyse,INGMenuItemAppointment,INGMenuItemInfo,INGMenuItemSettings};

（不带星*号）声明 int 数组，以及

int *currentEnv;

作为指向 int 的指针。然后您可以分配 egcurrentEnv = openEnv以便currentEnv指向 的元素openEnv。
