ios - Xcode 7 键盘控制功能错误

Question

我试图创建一个功能，以便通过单击键盘外部或键盘内的回车键来收起键盘，但不幸的是，它仅在我单击键盘外部时才起作用，按键盘不起作用键盘上的返回键。

import UIKit

class ViewController: UIViewController,UITextFieldDelegate {

@IBOutlet var numberEnter: UITextField!


@IBAction func findButton(sender: AnyObject) {

    resultLabel.text = numberEnter.text
}


@IBOutlet var resultLabel: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

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

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    self.view.endEditing(true)
}

func textFieldShouldReturn(textField:UITextField) -> Bool{

textField.resignFirstResponder()

return true

}

}

Answer 1

如果您尚未为文本字段设置委托(delegate)，则需要执行此操作。您可以在 Interface Builder 或代码中设置委托(delegate)。请参阅此 StackOverflow 答案作为示例:Text Field Should Return, is this correct for ios7?
