[["A1","A2","A3"],["B1","B2","B3"],["C1","C2"]]I want to show this values in picker view. Show before this values I have another array mother of this array. [A,B,C] if I selected A, second picker view contains A1,A2,A3 similar for B and C. My problem begins after here. I have to know selected item id. This id not row. For example A1 id is 33. A2 id is 34 ...
