let observable = Observable<thing>()
订阅Observables
observable.subscribe(
onNext: { thing in ... }, // do something with thing onError: { error in ... }, // do something with error onDone: { ... } //do something when it's done)
Closures are optional too...
observable.subscribe(
onNext: { thing in ... } // do something with thing)
observable.subscribe(
)
创建Observables变量let variable = Variable<whatever>(some initial value)
let optionalString = Variable<String?>(nil)
optionalString.asObservable().subscribe(
)
optionalString.value = "something"
let int = Variable<Int>(12)
int.asObservable().subscribe(
)
int.value = 42
其他变量let just = Just(1) // always returns the initial value (1 in this case)
enum TestError: Error {
case test
}
let failure = Fail(TestError.test) //always fail with error
let n = 5
let replay = Replay(n) // replays the last N events when a new observer subscribes
let control = UIControl()
control.controlEvent(.touchUpInside).subscribe(
onNext: { ... } // do something with thing
)
let button = UIButton()
button.tap.subscribe(
onNext: { ... } // do something with thing
)
