------ Solution ---------------------------------------- ----
how to structure a struct variable into NSMutableArray in it ? Similar with the numerical variables , but this is to convert it to NSValue object.
Assuming structure :
struct testStruct {
int value1;
int value2;
};
deposit code
struct testStruct t;
t.value1 = 1;
t.value2 = 2;
/ / struct object will be loaded into the NSArray in
[testArray addObject: [NSValue value: & t withObjCType: @ encode (struct testStruct)]];
extracted code
struct testStruct p;
[[testArray objectAtIndex: 0] getValue: & p];
