我是RxSwift的新手。很新通常,要在没有Rx的情况下链接您,可以将下一个函数放入补全闭包中。同行们告诉我改用flatmap或我们的concatmap版本,但从未给我提供示例。任何人都可以使用flatmap或concatmap的快速版本转换此代码吗?我还是新手,请谨慎对待判断。
SVProgressHUD.show()
params.address = address
print(params)
viewmodel
.postSeekerAvatar(image: image).subscribe(onSuccess: {
// SVProgressHUD.dismiss()
// SVProgressHUD.show()
self.viewmodel
.updateSeeker(withFirstName: params.firstName, lastName: params.lastName, isBusiness: params.isBusiness, abn: "none", address: params.address)
.subscribe(onSuccess: {
SVProgressHUD.dismiss()
self.performSegue(withIdentifier: SegueConstants.toProfileForm, sender: self)
}) { (error) in
SVProgressHUD.showDismissableError(with: error.message)
}.disposed(by: self.disposeBag)
}) { (error) in
SVProgressHUD.showDismissableInfo(with: error.message)
}.disposed(by: disposeBag)

postSeekerAvatar() method should return a Single response
Add showLoader/hideLoader method in BaseViewController.
viewmodel
.postSeekerAvatar(image: image) //Return Single<Response>
.do(onSubscribed: presenter.showLoader)
.do(onDispose: presenter.hideLoader)
.asCompletable()
.andThen(update(params: params))
.subscribe()
.disposeOnDeactivate(interactor: self)
//Returns a completable
private func update(params: Model) -> Completable {
viewmodel
.updateSeeker(
withFirstName: params.firstName,
lastName: params.lastName,
isBusiness: params.isBusiness,
abn: "none",
address: params.address
)
return Completable.empty()
}

因此,您想要的永远不会嵌套subscribe
调用。取而代之的是,您将源可观察的值转换为其他可观察的值,有时将其转换为另一个值。
SVProgressHUD.show()
params.address = address
print(params)
viewmodel
.postSeekerAvatar(image: image)
.flatMap {
self.viewmodel
.updateSeeker(withFirstName: params.firstName, lastName: params.lastName, isBusiness: params.isBusiness, abn: "none", address: params.address)
}
.subscribe(onSuccess: {
SVProgressHUD.dismiss()
self.performSegue(withIdentifier: SegueConstants.toProfileForm, sender: self)
}, onError: { (error) in
SVProgressHUD.showDismissableError(with: error.message)
})
.disposed(by: disposeBag)
因此,在这里,第一个postSeekerAvatar
将被订阅,并且每次推出一个值时,updateSeeker
也将被订阅。如果它们中的任何一个出错,错误关闭将运行。
