Hello! i am developing an ios app to connect to product.product and i am trying to make a simple search call, this is how i am doing it:

NSArray *arr = [NSArray arrayWithObjects:@"active", @"=", YES, nil];

    NSArray *arri =[NSArray arrayWithObjects:arr, nil];

    [request2 setMethod:@"execute" withParameters:[NSArray arrayWithObjects:@"db_ms",1,@"pass1", @"product.product", @"search", arri, nil]];

but it's giving me Thread 1:EXC_BAD_ACCESS(code =2, adress=0x1) when creating arr array, i don't know what i am doing wrong.

I already managed to login with this code:

XMLRPCRequest *request = [[XMLRPCRequest alloc] initWithURL:[NSURL URLWithString:@"http://192.168.1.106:8069/xmlrpc/common"]];

    XMLRPCConnectionManager *manager = [XMLRPCConnectionManager sharedManager];

    [request setMethod:@"login" withParameters:[NSArray arrayWithObjects:@"db_ms",@"admin",@"pass1", nil]];

and it worked. I don't know what is the syntax to pass values to the search, i would appreciate some help.
