RxSwift、MVVM - 无法使用 RxSwift 绑定实现 UITableViewDataSource 方法

Question

I am implementing a simple UITableView of addresses using RxSwift and MVVM. I have created a binding in my view controller like this.

viewModel.addressList.asDriver()
   .drive(tableView.rx_itemsWithCellIdentifier(reusableIdentifier, cellType: SavedAddressTableViewCell.self)) { [weak self] (row, viewModel, cell) in
        self?.setUpAddressCell(cell, row: (row + 1))
    }
    .addDisposableTo(disposeBag)

However, I keep getting this error when I try to open the page in my app.

Maybe delegate was already set in `xib` or `storyboard` and now it's being overwritten in code.

I Googled and found that I have to set tableView.delegate and tableView.dataSource to nil.

However, there are some UITableViewDataSource methods that I still need, like

canEditRowAtIndexPath
commitEditingStyle

for deleting addresses.

How should I implement this? Thanks in advance.

Answer 1

在上面写这一行：

tableView.dataSource = nil

Answer 2

Okay I found the solution.

Use RxDataSources.

I really didn't want to use a new pod for this, but I couldn't find an alternative solution.

Okay I did find an alternative solution now!

Use

tableView.rx_itemDeleted

This function is ReactSwift's wrapper for commitEditingStyle (misleading yes!), whatever you would have written in commitEditingStyle you can now write in this function. For canEditRowAtIndexPath, I always wanted to return true, which is the default return value even if I don't write code for that, so I didn't have to implement canEditRowAtIndexPath at all!
