ReactiveCocoa v5.0.3 發布

ReactiveCocoa的核心為signals即RACSignal類。Signals發出三種類型的事件流:next、completed、和error。
通過此模式,ReactiveCocoa可以用來替代delegate、target-action、key-value observing等模式。
通過signal API創建的代碼更加統一且易讀.但ReactiveCocoa真正強大之處在于通過這些信號源能進行更多高級操作.這些操作能在相當簡潔高雅的操作下執行復雜的篩選、轉換、信號協調等。在MVVM中,ReactiveCocoa扮演著重要角色.它提供ViewModel和View之間的綁定操作。
更新日志
- New KVO API:
NSObject.reactive(self:).signal(forKeyPath:). (#3413, kudos to @Burgestrand) - New binding targets for
UINavigationItemandUITabBarItem. (#3444, kudos to @Marcocanc) - New binding targets for
UIFeedbackGeneratorand its subclasses. (#3447, kudos to @Marcocanc) NSObject.reactive(self:).values(forKeyPath:)is deprecated and replaced byNSObject.reactive(self:).producer(forKeyPath:). (#3413)- The KVO API now supports object values that are of native Swift classes properly. (#3439, kudos to@andersio)
- A bug that could lead to deadlocks and unexpected
nilin the KVO API on any arbitrary key path was fixed. (#3439) - Continuous text signals of
UITextFieldnow emits the latest value for all editing events emitted. In other words, replacements due to autocompletions are now covered by the signals. (#3442 , kudos to@andersio) - Fixed a ObjC swizzling bug that caused
ActionProxynot working well with KVO and RAC method interception. (#3435, kudos to @andersio)
