使用自定义 inputView 将输入返回到 UITextfield

发布于 2024-09-08 20:51:34 字数 429 浏览 5 评论 0原文

我创建了一个 UITextField 和一个自定义视图。之后，我将此自定义视图作为“inputView”添加到我的 UITextField 中。

 amountKeyboardViewController *amountKeyboard = [[amountKeyboardViewController alloc] initWithNibName:@"amountKeyboardViewController" bundle:nil];

amountTextField.inputView = amountKeyboard.view;

[amountTextField becomeFirstResponder];

这工作得很好。但是我可以用在自定义视图（UIButtons）中单击的输入来填充“amountTextField”吗？

感谢您的一些提示！

i created a UITextField and a custom View.
after that i added this custom view as "inputView" to my UITextField.

 amountKeyboardViewController *amountKeyboard = [[amountKeyboardViewController alloc] initWithNibName:@"amountKeyboardViewController" bundle:nil];

amountTextField.inputView = amountKeyboard.view;

[amountTextField becomeFirstResponder];

this works quite fine. but can i fill my "amountTextField" with the input clicked in my custom View (UIButtons)?

thanks for some hints !

在您的 amountTextField 控制器中，您需要在 .h 文件中编写以下代码

创建文本字段的属性

@property(nonatomic,retain)UiTextField *txt; //whatever your textfield name

现在在 .m 文件中编写以下编写以下

@synthesize txt;

语句，在其中创建 amountKeyboardViewController 对象

 amountKeyboardViewController *amountKeyboard = [[amountKeyboardViewController alloc] initWithNibName:@"amountKeyboardViewController" bundle:nil]
 amountKeyboard.objamountTextField = self;

现在在 amountKeyboardViewController 控制器中编写以下代码，

@class amountTextField;       //forward declaration

然后创建此对象类

amountTextField *objamountTextField;

创建 Now 属性

@property(nonatomic,retain)amountTextField *objamountTextField;

然后单击按钮

-(IBAction)clickof1
{
    if([amountTextField.text length] <= 0)
        objamountTextField.txt.text = @"1";
    else
        objamountTextField.txt.text=[objamountTextField.txt.text stringByAppendingString:@"1"];
}

in your amountTextField controller you need to write the following code in .h file

create property of your textfield

@property(nonatomic,retain)UiTextField *txt; //whatever your textfield name

Now in .m file write the following

@synthesize txt;

write following statement where you create object of amountKeyboardViewController

 amountKeyboardViewController *amountKeyboard = [[amountKeyboardViewController alloc] initWithNibName:@"amountKeyboardViewController" bundle:nil]
 amountKeyboard.objamountTextField = self;

Now in amountKeyboardViewController controller write the following code

@class amountTextField;       //forward declaration

then create object of this class

amountTextField *objamountTextField;

then create property of

@property(nonatomic,retain)amountTextField *objamountTextField;

Now on click of button

-(IBAction)clickof1
{
    if([amountTextField.text length] <= 0)
        objamountTextField.txt.text = @"1";
    else
        objamountTextField.txt.text=[objamountTextField.txt.text stringByAppendingString:@"1"];
}

您的意思是，如果您按 1，则文本字段中应显示“1”。

之后，如果您按 2，则会显示“12”。

你想要这样吗？

你必须为所有按钮编写IBaction
例如。

-(IBAction)clickof1
{
    if([amountTextField.text length] <= 0)
       amountTextField.text = @"1";
    else
       amountTextField.text = [amountTextField.text stringByAppendingString:@"1"];
}

-(IBAction)clickof2
{
    if([amountTextField.text length] <= 0)
       amountTextField.text = @"2";
    else
       amountTextField.text = [amountTextField.text stringByAppendingString:@"2"];
}

就像你必须为所有按钮编写 IBaction

You mean that if you press 1 then '1' should shown in textfield.

after that if you press 2 then it will show '12'.

Do you want like this?

You have to write IBaction for all buttons
eg.

-(IBAction)clickof1
{
    if([amountTextField.text length] <= 0)
       amountTextField.text = @"1";
    else
       amountTextField.text = [amountTextField.text stringByAppendingString:@"1"];
}

-(IBAction)clickof2
{
    if([amountTextField.text length] <= 0)
       amountTextField.text = @"2";
    else
       amountTextField.text = [amountTextField.text stringByAppendingString:@"2"];
}

like that you have to write IBaction for all your buttons
