单个textfield校验
nameTextfield.rx.text.orEmpty
.map { $0.count > 1 } // $0代表第一个参数，就是输入内容必须大于1位
.share(replay: 1)
.subscribe(onNext: {[weak self] (bool) in
self?.loginBut.isEnabled = bool // 修改按钮是否可以点击
self?.loginBut.backgroundColor = bool == true ? ThemeBlue : ThemeGreyBlue
}, onError: { (error) in
}, onCompleted: nil, onDisposed: nil)
.disposed(by: disposeBag)
