UISegmentedControl

    segment.rx.selectedSegmentIndex.asObservable()
        .subscribe(onNext:{
            print("选择了第\($0)个")
        })
        .disposed(by: disposeBag)
    

UIActivityIndicatorView

通过UISwict控制UIActivityIndicatorView是否旋转，也可以控制左上角网络是否是否旋转。

    switch1.rx.isOn
        .bind(to: activityView.rx.isAnimating)
        .disposed(by: disposeBag)
    
    switch1.rx.isOn
        .bind(to: UIApplication.shared.rx.isNetworkActivityIndicatorVisible)
        .disposed(by: disposeBag)

UISlider

    slider.rx.value.asObservable()
        .subscribe(onNext:{
            print("UISlider当前的值：\($0)")
        })
        .disposed(by: disposeBag)

UIStepper

    steper.rx.value.asObservable()
        .subscribe(onNext:{
            print("UIStepper当前的值：\($0)")
        })
        .disposed(by: disposeBag)

通过修改UIStepper的值来改变slider的值

    steper.rx.value.asObservable()
        .map({Float($0)})
        .bind(to: slider.rx.value)
        .disposed(by: disposeBag)

UIDatePicker

    datePicker.rx.date
        .map{ [weak self] in
            "选中的时间:"  + self!.dateFormater.string(from: $0)
        }
        .bind(to:label.rx.text)
        .disposed(by: disposeBag)

UIPickerView

导入RxDataSources使用起来更方便
单列的情况

    private let adapter1 = RxPickerViewStringAdapter<[String]>(
        components: [],
        numberOfComponents: { _,_,_  in 1 },
        numberOfRowsInComponent: { (_, _, items, _) -> Int in
            return items.count},
        titleForRow: { (_, _, items, row, _) -> String? in
            return items[row]}
    )
    
    Observable.just(["1","2","3"])
        .bind(to: pickerView.rx.items(adapter: adapter1))
        .disposed(by: disposeBag

多列的情况

    private let adapter2 = RxPickerViewStringAdapter<[[String]]>(
        components: [],
        numberOfComponents: { dataSource,pickerView,components  in components.count },
        numberOfRowsInComponent: { (_, _, components, component) -> Int in
            return components[component].count},
        titleForRow: { (_, _, components, row, component) -> String? in
            return components[component][row]}
    )
    
    Observable.just([["1","2","3"],["A","B","C"]])
        .bind(to: pickerView2.rx.items(adapter: adapter2))
        .disposed(by: disposeBag)

手势

对UIGestureRecognizer增加了响应方法，手势使用方法都一致。

    //滑动手势
    swipeGesture.rx.event
        .subscribe(onNext:{ [weak self] recognizer in
            let point = recognizer.location(in: recognizer.view)
            self?.showMessage(text: "上滑了",message: "x:\(point.x) y: \(point.y)")
        })
        .disposed(by: disposeBag)
    
    //点击手势
    tapGesture.rx.event
        .subscribe(onNext:{ [weak self] recognizer in
            let point = recognizer.location(in: recognizer.view)
            self?.showMessage(text: "点击了",message: "x:\(point.x) y: \(point.y)")
        })
        .disposed(by: disposeBag)
