iOS遍曆數組相同值元素到同一對象的子數組

標籤：ios

saledGoodsArray數組中儲存商品對象saledgoods，saledgoods有seatNo屬性，將saledGoodsArray數組中saledgoods對象相同座位兒號的商品賦值給同一個人(personObject)的購買商品數組(purchasedGoodsArr)。

剛發現可以這樣寫，慚愧得緊！

  dataArray = [[NSMutableArray alloc] init];    saledGoodsArray = [ShoppingCartDataCenter queryNoPayGoodsByFlightID:@"8815"];    NSMutableDictionary *personObjectDics = [[NSMutableDictionary alloc] init];    for (NSInteger i=0; i<saledGoodsArray.count; i++) {        SaledGoods *saledgoods = [saledGoodsArray objectAtIndex:i];        SCPersonObject * personObject = [personObjectDics objectForKey:[saledgoods seatNo]];        if (!personObject) {            personObject = [[SCPersonObject alloc] init];            [[personObject purchasedGoodsArr] addObject:saledgoods];            [personObjectDics setObject:personObject forKey:[saledgoods seatNo]];        }else {            [[personObject purchasedGoodsArr] addObject:saledgoods];        }    }    for (SCPersonObject * personObject in [personObjectDics allValues]) {        if ([personObject isKindOfClass:[SCPersonObject class]]) {            [dataArray addObject:personObject];        }    }
