状态事件类

  • 事件名称，只读

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSString *_Nonnull name;

  • 来源状态列表，只读

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly) NSArray<FWState *> *_Nonnull sourceStates;

  • 目标状态，只读

    Declaration

    Objective-C

    @property (nonatomic, strong, readonly) FWState *_Nonnull targetState;

  • 能否触发block

    Declaration

    Objective-C

    @property (nonatomic, copy, nullable) BOOL (^) (FWStateTransition *_Nonnull __strong) shouldFireBlock;

  • 即将触发block

    Declaration

    Objective-C

    @property (nonatomic, copy, nullable) void (^) (FWStateTransition *_Nonnull __strong) willFireBlock;

  • 正在触发block，必须调用completion标记完成结果。YES事件完成、状态改变，NO事件失败、状态不变。不设置默认完成

    Declaration

    Objective-C

    @property (nonatomic, copy, nullable) void (^) (FWStateTransition *_Nonnull __strong, void (^_Nonnull __strong)(BOOL)) fireBlock;

  • 触发完成block，finished为完成状态

    Declaration

    Objective-C

    @property (nonatomic, copy, nullable) void (^) (FWStateTransition *_Nonnull __strong, BOOL) didFireBlock;

  • 初始化事件

    Declaration

    Objective-C

    + (nonnull instancetype)eventWithName:(nonnull NSString *)name
                           fromStates:(nonnull NSArray<FWState *> *)sourceStates
                              toState:(nonnull FWState *)targetState;
