我创建了一个UITextField和一个自定义视图。

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

amountTextField.inputView = amountKeyboard.view;

[amountTextField becomeFirstResponder];

这个很好用。但是我可以用在自定义视图(UIButtons)中单击的输入填充“amountTextField”吗?

谢谢你的提示!

在amountTextField控制器中,需要在.h文件中编写以下代码

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

现在在.m文件中编写以下命令

@synthesize txt;

在创建amountKeyboardViewController对象的位置编写以下语句

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

现在在amountKeyboardViewController中编写以下代码

@class amountTextField;       //forward declaration

amountTextField *objamountTextField;

然后创建属性

@property(nonatomic,retain)amountTextField *objamountTextField;

现在点击按钮

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

你的意思是如果你按1,那么“1”应该显示在文本字段中。

你想要这样吗?

您必须为所有按钮编写iAction

-(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"];
}

像这样,你必须为你所有的按钮写iAction
