如何在NVActivityIndi catorView中使用RxSwift？

Question

我正在尝试使用NVActivityIndicatorView和RxSwift和MVVM。我正在扩展NVActivityIndicatorView如下：

extension Reactive where Base: NVActivityIndicatorView {

/// Bindable sink for `startAnimating()`, `stopAnimating()` methods.
public var isAnimating: Binder<Bool> {
    return Binder(self.base) { activityIndicator, active in
        if active {
            activityIndicator.startAnimating()
        } else {
            activityIndicator.stopAnimating()
        }
    }
}}

和绑定数据如下：

splashVM.loading.bind(to: NVActivityIndicatorView.rx.isAnimating).disposed(by: disposeBag)

但我得到错误：

Instance member 'isAnimating' cannot be used on type 'Reactive<NVActivityIndicatorView>'

如果我设置isAnimation静态，该错误消失但弹出另一个错误：

Instance member 'base' cannot be used on type 'Reactive<Base>'

究竟是什么问题？我应该改变什么？

你绑定错了。您需要绑定到特定活动指示器视图而不是类：

let activityIndicatorView: NVActivityIndicatorView

splashVM.loading
    .bind(to: activityIndicatorView.rx.isAnimating)
    .disposed(by: disposeBag)
