我有以下代码:
loginViewModel.facebookLogin
.asObservable()
subscribe() { [unowned self] facebookLogin in
if let isLoggedIn = facebookLogin.element?.isLoggedIn {
if isLoggedIn {
elf.performSegue(withIdentifier: "toRestaurantSelect", sender: self)
}
}
if let didLoginFail = facebookLogin.element?.didLoginFail {
self.errorLabel.isHidden = !didLoginFail
}
}
.disposed(by: disposeBag)
facebookLogin是一个变量,并在用户登录时更新。但是,不调用performSegue(条件为true)。奇怪的是,如果我在模拟器中打开慢速动画,则会执行segue。当关闭慢速动画时,将不会执行搜索(Facebook登录有效)。任何帮助表示赞赏。谢谢!
最佳答案
我认为你应该使用主线程来使其工作
loginViewModel.facebookLogin
.asObservable()
.subscribe() { [unowned self] facebookLogin in
if let isLoggedIn = facebookLogin.element?.isLoggedIn {
if isLoggedIn {
DispatchQueue.main.async {
self.performSegue(withIdentifier: "toRestaurantSelect", sender: self)
}
}
}
if let didLoginFail = facebookLogin.element?.didLoginFail {
self.errorLabel.isHidden = !didLoginFail
}
}
.disposed(by: disposeBag)
关于ios - swift-performSegue在RxSwift中不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/50668925/
