I came across the requirement where I need to sort my information based on various condition like
1. Sort the item details in ascending order based on Selling price
2. If selling price are same, then sort the item details in ascending order based on item name
3. If selling price and item name are same then sort based existing of monogramming information
We usually call it as Multi level sorting. I just done it by using below code.
//sort the values [arrItem sortUsingComparator:^NSComparisonResult (id a, id b){ ItemDetail * itemA = (ItemDetail*)a; ItemDetail* itemB =(ItemDetail*)b; //item price are same if (itemA.m_price.m_selling== itemB.m_price.m_selling) { NSComparisonResult result= [itemA.m_itemName compare:itemB.m_itemName]; //if item names are same, then monogramminginfo has to come before the non monograme item if (result==NSOrderedSame) { if (itemA.m_monogrammingInfo) { return NSOrderedAscending; }else{ return NSOrderedDescending; } } return result; } //asscending order return itemA.m_price.m_selling > itemB.m_price.m_selling; }];
Cheers:), Please let me know if you have queries for the same.
