单选、全选处理

//全选
- (IBAction)clikeMainSleocted:(UIButton *)sender {
    
    allprice = 0;
     __weak typeof(self) weakSelf = self;
    
    [self.data enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        
        WineModel *mod = obj;
        mod.seleoctedShop = !sender.selected;

        
        if(mod.seleoctedShop == NO){
            
            self.moneyMain.text = @"0";
        }else{
            
            int  total = mod.money.intValue * mod.shopCount;
            allprice = allprice + total;
            weakSelf.moneyMain.text = [NSString stringWithFormat:@"%d",allprice];
            
        }
        
         
    }];
    
    [self.table reloadData];

    sender.selected = ! sender.selected;
}
//选中
- (void)TableViewCellWithClikeSeleocCell:(TableViewCell *)cell{
    
    if(cell.mod.seleoctedShop){
        
        int total =  self.moneyMain.text.intValue + cell.mod.money.intValue * cell.mod.shopCount;
        self.moneyMain.text = [NSString stringWithFormat:@"%d",total];
        
    }else{
        
        int total =  self.moneyMain.text.intValue -   cell.mod.money.intValue * cell.mod.shopCount;
        self.moneyMain.text = [NSString stringWithFormat:@"%d",total];

    }
    
    
    if(self.shopCar.count == self.data.count){
        
        self.seleocMain.selected = YES;
    }else{
        self.seleocMain.selected = NO;
    }
    
}

加、减处理

//加
- (void)TableViewCellWithClikeAddCell:(TableViewCell *)cell{
    
    int main = self.moneyMain.text.intValue + cell.mod.money.intValue;
    self.moneyMain.text = [NSString stringWithFormat:@"%d",main];
    if(![self.shopCar containsObject:cell.mod]){
        
        [self.shopCar addObject:cell.mod];
    }
    
}
//减
- (void)TableViewCellWithClikeDeleocCell:(TableViewCell *)cell{
    
    int main = self.moneyMain.text.intValue - cell.mod.money.intValue;
    self.moneyMain.text = [NSString stringWithFormat:@"%d",main];
    if(cell.mod.shopCount == 0){
        
        [self.shopCar removeObject:cell.mod];
    }
}
