如何将 RxSwift 与 NVActivityIndicatorView 一起使用?
How to use RxSwift with NVActivityIndicatorView?
我正在尝试将 NVActivityIndicatorView
与 RxSwift
和 MVVM
一起使用。
我正在扩展 NVActivityIndicatorView
,如下所示:
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()
}
}
}}
并像这样绑定数据:
splashVM.loading.bind(to: NVActivityIndicatorView.rx.isAnimating).disposed(by: disposeBag)
但是我得到了这个错误:
Instance member 'isAnimating' cannot be used on type 'Reactive<NVActivityIndicatorView>'
如果我将 isAnimation
设置为静态,该错误就会消失,但会弹出另一个错误:
Instance member 'base' cannot be used on type 'Reactive<Base>'
到底是什么问题?我应该改变什么?
你绑定错了。您需要绑定到特定的 activity 指标视图而不是 class:
let activityIndicatorView: NVActivityIndicatorView
splashVM.loading
.bind(to: activityIndicatorView.rx.isAnimating)
.disposed(by: disposeBag)
