自定义iPad键盘，看起来像系统键盘-CustomiPadkeyboardthatlookslikethesystemkeyboards

I used the following:

我使用了以下内容：

tenDigitKeyboard.m

tenDigitKeyboard.m

-(IBAction)pressedKey:(UIButton *)sender
{
    [delegate pressedKey:sender.tag];
}

where delegate is defined as `id delegate;

其中delegate被定义为`id delegate;

then in the delegate i do...

然后在代表中我做...

-(void)pressedKey:(NSInteger)key
{
    NSString * bufferString = model.string;
    if (key == -1) {//delete
        model.string = [bufferString substringWithRange:NSMakeRange(0, [bufferString length]-1)];
    }else{
     //will need to change the following to lookup key value based on a lookup of the button.tag
        model.string = [bufferString stringByAppendingFormat:@"%i",key];
    }
    [self update];//updates the view
}

I got the keyboard button artwork from: http://www.teehanlax.com/blog/iphone-gui-psd-v4/

Create a view controller and xib. The xib should have 1-9,0 and delete buttons mapped to IBOutlets in your controller. Store and retain the return value string as a property. You can add decimals, etc. if you wish. In the header, store an edition block closure with a property (or alternatively create a delegate or use notification).

创建一个视图控制器和xib。 xib应该有1-9,0并且删除按钮映射到控制器中的IBOutlets。存储并保留返回值字符串作为属性。如果您愿意，可以添加小数等。在标题中，使用属性存储版块闭包（或者创建委托或使用通知）。

@property (copy) void(^valueChangedBlock)(NSString* string);

On touch up, each button sends an event to a method like this:

在修饰时，每个按钮都会向这样的方法发送一个事件：

- (IBAction) pressKey:(id)sender
{
    NSString *toAppend;

    // Instead of this switch you can store the values in a dictionary mapped by sender.
    switch(sender)
    {
        case oneButton: toAppend=@"1"; break;
        case twoButton: toAppend=@"2"; break;
        ...
    }

    returnValue = [returnValue appendString:toAppend];
    valueChanged(returnValue);
}

Obviously the delete key should remove a character from the end of the string instead of appending. Other than creating the controller and adding this view as the inputView, you should add the valueChangedBlock and set it to update the text field. You may want to put a clear custom button over the text field set to make the field first responder so it doesn't appear as if the user can edit at any point in the string.

显然，删除键应该从字符串的末尾删除一个字符而不是追加。除了创建控制器并将此视图添加为inputView之外，您应该添加valueChangedBlock并将其设置为更新文本字段。您可能希望在文本字段集上放置一个清晰的自定义按钮，以使字段成为第一响应者，这样就不会显示用户可以在字符串中的任何位置进行编辑。
