swift – Promise.onSuccess立即调用

概述我正在使用 BrightFutures,当我运行以下代码时,在geoCoder completionHandler完成之前调用sequence().onComplete和sequence().onSuccess.你能帮助我吗？ self.uploadContentSequence = [Future<Future<Void, NoError>, NoError>]();for post in 我正在使用 BrightFutures,当我运行以下代码时,在geoCoder completionHandler完成之前调用sequence().onComplete和sequence().onSuccess.你能帮助我吗？

self.uploadContentSequence = [Future<Future<VoID,NoError>,NoError>]();for post in posts {     self.uploadContentSequence.append(future(self.preparePostUpload(post)))}self.uploadContentSequence.sequence().onComplete { (_) -> VoID in    print("onComplete")}.onSuccess { (_) -> VoID in    print("onSuccess")}.onFailure { (_) -> VoID in    print("onFailure")}[...]func preparePostUpload(post: Post) -> Future<VoID,NoError> {    let promise = Promise<VoID,NoError>()    [...]    let postLocation = CLLocation(latitude: Double(post.lat!),longitude: Double(post.lng!))    let geocoder = CLGeocoder();    let countryCode = NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String    post.country = countryCode    geocoder.reverseGeocodeLocation(postLocation,completionHandler: { (placemarks,locError) -> VoID in        [...]        promise.success()    });    return promise.future}

解决方法 正如phimage在本期杂志中所指出的那样： https://github.com/Thomvis/BrightFutures/issues/111我将在未来完成未来. 总结
