|*| 关闭 UITextField 的键盘：覆盖 ViewController 的 touchesBegan:withEvent: 方法
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?)
{
view.endEditing(true)
super.touchesBegan(touches, withEvent: event)
}
|或|
override func viewDidLoad()
{
super.viewDidLoad()
// For tapping outside text box
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(DismisKeyPadFnc)))
}
// For tapping outside text box
func DismisKeyPadFnc()
{
view.endEditing(true)
}
|*| 关闭单个文本框上的 UITextField 键盘：
class NamVcc: UIViewController, UITextFieldDelegate
{
@IBOutlet var NamTxtBoxVid: UITextField!
override func viewDidLoad()
{
super.viewDidLoad()
// For hitting return key
NamTxtBoxVid.delegate = self
// For tapping outside text box
self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(DismisKeyPadFnc)))
}
/* For hitting return key */
func textFieldShouldReturn(NamTxtBoxPsgVid: UITextField) -> Bool
{
NamTxtBoxPsgVid.resignFirstResponder()
return true
}
/* For tapping outside text box */
func DismisKeyPadFnc()
{
view.endEditing(true)
}
}
|*| 实现下一步按钮单击：
1）您将需要在 xib/Storyboard 或代码中的文本字段的增量序列中设置标签。
2) 为每个文本字段设置委托。
3）然后将以下代码粘贴到您的视图控制器中以获得所需的效果：
func textFieldShouldReturn(TxtBoxPsgVar: UITextField) -> Bool
{
let NxtTxtBoxTagVal : Int = TxtBoxPsgVar.tag + 1
let NxtTxtBoxVal: UIResponder? = TxtBoxPsgVar.superview?.superview?.viewWithTag(NxtTxtBoxTagVal)
if let TxtBoxVal = NxtTxtBoxVal
{
// Found next responder, so set it.
TxtBoxVal.becomeFirstResponder()
}
else
{
// Not found, so remove keyboard.
TxtBoxPsgVar.resignFirstResponder()
}
return true
}
