标签:插入 tps lis scribe 操作 with let zip publish
在订阅的时候插入发送事件,后加入的先发送。完成事件发送时不会插入。
let ob = PublishSubject<String>()
ob.startWith("插入1").startWith("插入2").subscribe(onNext: { element in
print(element)
}).disposed(by: disposeBag)
ob.onNext("发送1")
插入2
插入1
发送1
合并操作,将多个 Observable
合并成一个
let ob1 = PublishSubject<String>()
let ob2 = PublishSubject<String>()
Observable.of(ob1,ob2).merge().subscribe { (event) in
print(event)
}.disposed(by: disposeBag)
ob1.onNext("ob1 发1")
ob2.onNext("ob2 发1")
ob1.onNext("ob1 发2")
ob2.onNext("ob2 发2")
将 n 个Observable
压缩成一个发送事件,必须每个都参与的发送完才会发送一次事件。参与的成对发送完
let ob1 = PublishSubject<String>()
let ob2 = PublishSubject<String>()
Observable.zip(ob1,ob2).subscribe { (event) in
print(event)
}
ob1.onNext("ob1 2")
ob1.onNext("ob1 3")
ob2.onNext("ob2 A")
ob2.onNext("ob2 B")
ob2.onNext("ob2 C")
ob1.onNext("ob1 1")
//next(("ob1 2", "ob2 A"))
//next(("ob1 3", "ob2 B"))
//next(("ob1 1", "ob2 C"))
8. RxSwift 插入发送合并压缩 startWith、merge、zip
