swift中，textField中：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | //3. username/phone number textFiled let textFieldPaddingX:CGFloat = 10 let textFieldPaddingY:CGFloat = 20 let textFieldHeight:CGFloat = 40 usernameTextField.frame = CGRectMake( textFieldPaddingX, appNameLabel.frame.origin.y + appNameLabel.frame.height + 40,//self.view.bounds.height*0.4, self.view.bounds.width - (textFieldPaddingX * 2), textFieldHeight) usernameTextField.textAlignment = NSTextAlignment.Left usernameTextField.font = UIFont.systemFontOfSize(16) usernameTextField.borderStyle = UITextBorderStyle.RoundedRect usernameTextField.placeholder = "请输入用户名（手机号）" usernameTextField.autocorrectionType = UITextAutocorrectionType.No usernameTextField.keyboardType = UIKeyboardType.Default usernameTextField.returnKeyType = UIReturnKeyType.Done usernameTextField.clearButtonMode = UITextFieldViewMode.WhileEditing usernameTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.Center //4. password textFiled passwordTextField.frame = CGRectMake( usernameTextField.frame.origin.x, usernameTextField.frame.origin.y + usernameTextField.frame.height + textFieldPaddingY, usernameTextField.frame.width, usernameTextField.frame.height) passwordTextField.textAlignment = NSTextAlignment.Left passwordTextField.font = UIFont.systemFontOfSize(16) passwordTextField.borderStyle = UITextBorderStyle.RoundedRect passwordTextField.placeholder = "请输入密码" passwordTextField.secureTextEntry = true passwordTextField.autocorrectionType = UITextAutocorrectionType.No passwordTextField.keyboardType = UIKeyboardType.Default passwordTextField.returnKeyType = UIReturnKeyType.Done passwordTextField.clearButtonMode = UITextFieldViewMode.WhileEditing passwordTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.Center |
键盘可以出现，但是点击完成后，键盘不能消失：
搜：
swift keyboard show and dismiss
参考：
用代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | class LoginViewController: UIViewController, UITextFieldDelegate { //3. username/phone number textFiled。。。 usernameTextField.delegate = self //4. password textFiled。。。 passwordTextField.delegate = self /*************************************************************************** * UITextFieldDelegate Functions ***************************************************************************/ //called when 'return' key pressed. return NO to ignore. func textFieldShouldReturn(textField: UITextField) -> Bool { textField.resignFirstResponder() return true; } |
点击Done后，键盘就可以消失了：
