为什么 rx.text / rx.observe / rx.etc 不可用 (RxSwift)

Why are rx.text / rx.observe / rx.etc not available (RxSwift)

我用 Cocoapods 创建了一个简单的项目并安装了 RxSwift 和 RxCocoa。

我写过这段代码:

import UIKit
import RxSwift

class ViewController: UIViewController {

    @IBOutlet weak var field: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        //self.field.rx. (only suggests `base`)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

所以我应该可以 self.field.rx.text 对吧?但我只得到 self.field.rx.base

我错过了什么?

你也必须在顶部添加 import RxCocoa
