Question

I have five integers.I added all integers to a mutableArray and shuffled it.

int A = 1;
int B = 2;
int C = 3;
int D = 4;
int E = 5;

myArray = [2,1,3,5,4]; //shuffled array

is it possible to get variable names of each integer in the array?
please help me.

Answer 1

In this case NSDictionary would be feasible, you can store both the Variable Names and their Values:

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:@"1",@"A",@"2",@"B",@"3",@"C",@"4",@"D",@"5",@"E", nil];

Now you can fetch all the keys of the dictionary like:

NSArray *arr = [dict allKeys];      // which will be [A,B,C,D,E]

And you can fetch the values for those keys like:

for (int i=0; i<arr.count; i++) {
        NSLog(@"%@",[dict valueForKey:[arr objectAtIndex:i]]);  // Will print 1,2,3,4,5
    }
