Swift 2.0在一个视图控制器cellForRowIndexPath中包含两个表视图

Question

Ive seen a few questions here about this but no defitnive answer Im using an up to date version of Xcode and swift...

Im trying to work with two table views in one view controller here is my cellForRowIndexPath function

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    var cell: UITableViewCell!

    if(tableView == self.allTableView){

        cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! BMRadioAllTableViewCell

            cell.mixImage.image = mixPhotoArray[indexPath.item]

            let dateFormatter = NSDateFormatter()
            dateFormatter.dateFormat = "yyyy-MM-dd"
            cell.mixDateLabel.text = dateFormatter.stringFromDate(mixDateArray[indexPath.item])


    }

    if(tableView == self.featuredTableView){
    // SET UP THE NEXT TABLE VIEW

    }


    return cell
    }

Im getting the error "Value of type UITableViewCell has no member "xxxx" so its obviously not registering the change to cell I'm making in the if statement.

I have tried various other ways, like declaring the variable within the if statement and returning it there. But you get the error "Missing return in a function expected to return UITableViewCell" since you need to get it outside the if statement.

If you have two different cell types for two different tables, you should make your code look something like this:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    if(tableView == self.allTableView){
        var cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! BMRadioAllTableViewCell

        cell.mixImage.image = mixPhotoArray[indexPath.item]

        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd"
        cell.mixDateLabel.text = dateFormatter.stringFromDate(mixDateArray[indexPath.item])

        return cell;
    } else {
        var cell = ...
        // SET UP THE NEXT TABLE VIEW
        return cell
    }
}

There's no need to have a single generic cell variable that handles both tables.

The error doesn't really have to do with you trying to configure two table views.

Even though you're casting the result of dequeueReusableCellWithIdentifier:forIndexPath: to BMRadioAllTableViewCell , you are then assigning it to a variable of type UITableViewCell! . As such, it will be a compiler error for you to access fields of BMRadioAllTableViewCell .

You would either need to change the cell type to BMRadioAllTableViewCell , or have a locally scoped variable of the correct type that you configure and then assign to cell :

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell: UITableViewCell!

    if(tableView == self.allTableView){

        let bmRadioAllCell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! BMRadioAllTableViewCell

        bmRadioAllCell.mixImage.image = mixPhotoArray[indexPath.item]

        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd"
        bmRadioAllCell.mixDateLabel.text = dateFormatter.stringFromDate(mixDateArray[indexPath.item])

        cell = bmRadioAllCell
    }

    if(tableView == self.featuredTableView){
    // SET UP THE NEXT TABLE VIEW

    }


    return cell
}
