如何在文本字段上双击键盘 [英] How to get Keyboard on double tap on a text field

问题描述

我正在制作一个应用程序，我想要双击键盘，我通过使用textfield委托方法在单击时禁用了键盘：

I am making a application in which I want keyboard on double-tap, I have disabled keyboard on single tap by using textfield delegate method:

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField 
{
    return NO; 
}

之后我为textfield制作了一个动作方法

And after that I make a action method for textfield

[textField1 addTarget:self action:@selector(clicked) forControlEvents:UIControlEventTouchDownRepeat];

在这种方法中我使用了这段代码：

And in this method I used this code:

[textField1 becomeFirstResponder];

但这不起作用

建议我，我该怎么办？

推荐答案

首先创建一个Bool类型的类变量（比如说 BOOL shouldFire ）并将其初始化为NO。
并将 UITapGestureRecogniser 与点击次数= 2 添加到UITextField。

First create a class variable of type Bool (say BOOL shouldFire) and initialise it to NO. And add UITapGestureRecogniser with number of taps = 2 to the UITextField.

当连接到TapGesture的选择器触发时，使用下面的代码

When the selector attached to TapGesture fires, use below code

-(void)tapped:(UITapGestureRecogniser *)ges{
 _shouldFire=YES;
 [textField1 becomeFirstResponder];
}

并将您的方法更改为 - >

And change your method to->

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField 
{   
    if(self.shouldFire==YES){
      self.shouldFire=NO;
      return YES: 
    }
    return NO;
}
