如何将NSData转换为const uint8_t?或者在Wifi上传递NSData时出错

i have a array with two strings:

我有一个有两个字符串的数组:

NSArray *sendingArray = [[NSArray alloc]initWithObjects:@"CAT",@"DOG",nil];

and i converted the array to NSData:

我将数组转换为NSData

NSData *myData = [NSKeyedArchiver archivedDataWithRootObject:sendingArray];

now i need to convert my NSData(myData) to const uint8_t

现在我需要将我的NSData(myData)转换为const uint8_t。

i am doing this code to send an array of values through Wifi network.

我做这个代码是为了通过Wifi网络发送一个值数组。

i send successfully a string over wifi using the below code(my string is "string").

我使用下面的代码通过wifi成功发送了一个字符串(我的字符串是“string”)。

 const uint8_t *message = (const uint8_t *)[string UTF8String]; 

    [_outStream write:bytes maxLength:len];

i wrote the below code to send NSData object but it got error.

我写了下面的代码来发送NSData对象，但是它出错了。

code is:

代码是:

const uint8_t *bytes = (uint8_t)[myData bytes];//this line getting error.
    [_outStream write:bytes maxLength:len];

can i send my NSData(myData) through the above method without converting it to const uint8_t? if yes,please give me the code that i need to write.

我可以通过上面的方法发送NSData(myData)而不将其转换为const uint8_t吗?如果是，请给我需要写的代码。

or can any one tell me the way to convert my NSData(myData) to const uint8_t

或者谁能告诉我如何将NSData(myData)转换为const uint8_t

 const uint8_t *bytes = (const uint8_t*)[myData bytes];
