我有四个uint8_t数组:

uint8_t arrayOne[12]   = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x01,0xC1,0x00,0x01 };

uint8_t arrayTwo[12]   = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x4E,0x2D,0x00,0x0C };

uint8_t arrayThree[12] = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x01,0xF3,0x00,0x01 };

uint8_t arrayFour[12]  = { 0x00,0x01,0x00,0x00,0x00,0x06,0xFE,0x03,0x20,0x04,0x00,0x01 };

我已将它们添加到数组中:

uint8_t *theArray[] = { arrayOne,arrayTwo,arrayThree,arrayFour };

现在我想将此数组传递给方法,例如:

[self theMethod:theArray];

为:

-(void)theMethod:(uint8_t *)pointersArray[]{
...
...
}

将数组指向某个方法的正确方法是什么 - (void)theMethod ...?

2 个答案:

答案 0 :(得分:1)

这一行:

uint8_t *theArray = { arrayOne,arrayTwo,arrayThree,arrayFour };

实际上是创建一个数组,其中包含转换为uint8_t 值的数组的指针。我不认为这是你想要的。

首先(注意双指针):

uint8_t *theArray[] = { arrayOne,arrayTwo,arrayThree,arrayFour };

然后你的ObjC方法变为:

-(void)theMethod:(uint8_t **)pointersArray {

}

答案 1 :(得分:0)

声明您的方法以获取指向数组指针的指针

-(void)theMethod:(uint8_t **)pointersArray{
...
...
}

通过像

这样传递方法来调用方法
[self theMethod:&theArray];
