store uint8_t in NSMutableArray

in my program i am getting my receiving data from sensors in uint8_t type. I need to store those data in a NSMutable array.

i created a NSMutable array 

NSmutableArray *test;

initialize it

test = [[test alloc]init];

Then i tried to store data in my array 

[test addObject:Message.data7];

Message.data7 is in uint8_t format

But it want allow me to store like that way ,

Can any one explain me how to do that.

thanks in advance

Solution

  • You can't store simple primitives in NSArray/NSMutableArray. However, you can convert it to a NSNumber and store that:

    [test addObject:@(Message.data7)];

    When you want to retrieve the value from the array:

    uint8_t value = (uint8_t)[test[index] unsignedCharValue];
