升级到iOS Beta 13之后，我注意到了一件不愉快的事情：我的应用有时会因传入的VoIP推送而崩溃。
在崩溃报告中，我看到以下内容：

CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE …我有2个UITextField属性和1个UIButton的授权控制器.我想将View绑定到ViewModel,但不知道如何操作.这是我的AuthorizatioVC.swift:
class AuthorizationViewController: UIViewController {
let disposeBag = DisposeBag()
@IBOutlet weak var passwordTxtField: UITextField!
@IBOutlet weak var loginTxtField: UITextField!
@IBOutlet weak var button: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
addBindsToViewModel()
}
func addBindsToViewModel(){
let authModel = AuthorizationViewModel(authClient: AuthClient())
authModel.login.asObservable().bindTo(passwordTxtField.rx_text).addDisposableTo(self.disposeBag)
authModel.password.asObservable().bindTo(loginTxtField.rx_text).addDisposableTo(self.disposeBag)
//HOW TO BIND button.rx_tap here?
}
}
这是我的AuthorizationViewModel.swift:
final class AuthorizationViewModel{
private let disposeBag = DisposeBag()
//input
//HOW TO DEFINE THE PROPERTY WHICH WILL BE BINDED TO RX_TAP FROM THE BUTTON IN VIEW???
let authEvent = ???
let login = …我想取消订阅RxSwift中的Observable.为了做到这一点,我曾经将Disposable设置为nil.但在我看来,在更新到RxSwift 3.0.0-beta.2后,这个技巧不起作用,我无法取消订阅Observable:
//This is what I used to do when I wanted to unsubscribe
var cancellableDisposeBag: DisposeBag?
func setDisposable(){
cancellableDisposeBag = DisposeBag()
}
func cancelDisposable(){
cancellableDisposeBag = nil
}
那么可能有人可以帮我如何正确取消订阅Observable？
当我开始使用RxSwift时,我曾经BaseViewController使用RxSwift在我所有的控制器上创建和扩展它.BaseViewController.swift的代码:
class BaseViewController: UIViewController {
var mSubscriptions: CompositeDisposable?
func addSubscription(subscription: Disposable){
if(mSubscriptions == nil){
mSubscriptions = CompositeDisposable()
}
if let mSub = mSubscriptions{
mSub.addDisposable(subscription)
}
}
func unsubscribeAll(){
if let mSub = mSubscriptions{
mSub.dispose()
mSubscriptions = nil
}
}
override func viewWillDisappear(animated: Bool) {
super.viewWillDisappear(animated)
unsubscribeAll()
}
deinit{
unsubscribeAll()
}
}
我在我的子控制器中使用addSubscription(:_)方法.例如,一段代码来自:
class TasksViewController: BaseViewController{
overrided func viewWillAppear(){
//...
var subscribe = dataLoader.load(requestNetwork, dataManager: taskDataManager)
.observeOn(ConcurrentDispatchQueueScheduler(queue: queue))
.subscribe({ (event) -> Void in
//...
}) …如果在RxSwift中遇到错误,我需要发出一系列项目.在JAVA中,可以使用"onErrorResumeNext"运算符完成.但是我在Swift中找不到相同的运算符或它的替代品.
我的VC.swift中有两个Bool属性:
var isRecording = false
var isPlaying = false
在viewDidLoad()方法中我有这样的代码:
let observable = Observable.combineLatest(self.rx_observe(Bool.self, "isRecording"), self.rx_observe(Bool.self, "isPlaying")) { (val1, val2) -> Void in
if(val1 == false && val2 == false){
self.recordButton.enabled = true
self.playButton.enabled = true
self.recordButton.setImage(UIImage(named: "record"), forState: UIControlState.Normal)
self.playButton.setImage(UIImage(named: "play"), forState: UIControlState.Normal)
} else if(val1 == true && val2 == false){
self.recordButton.enabled = true
self.recordButton.setImage(UIImage(named: "stop"), forState: UIControlState.Normal)
self.playButton.enabled = false
} else if(val1 == false && val2 == true){
self.recordButton.enabled = false
self.playButton.enabled = true
self.playButton.setImage(UIImage(named: "stop"), …我尝试在Sierra OS上启动kamailio.当我使用"/ usr/local/sbin/kamailio -c"运行kamailio时出现此错误:
