实现键盘咔嗒声，丢失 [英] Implement a keyboard click sound, lost

问题描述

本网站上的每个人对我的iOS编程都非常有帮助，但我遇到了一个非常简单的功能。我已经找到了关于按钮触摸时实现工厂键盘点击声音的Apples文档，但我没有得到的是创建一个UIView的小部分部分。我有一个非常基本的计算器，按钮由标准的Round Rect制成，我想制作简单的咔嗒声。所以Apple说：采用UIInputViewAudioFeedback协议
执行以下三个步骤来采用UIInputViewAudioFeedback协议：

Everyone on this site has been very helpful on my schooling of iOS programming, but I've run into a brick wall with a very simple feature. I've found Apples documentation on implementing the factory keyboard click sound upon a button touch, but what Im not getting is the "creating a sub lass of UIView" part. I have a very basic calculator that I've built, the buttons are made of standard Round Rect's that I want to make the simple click sound. So Apple says:Adopting the UIInputViewAudioFeedback Protocol Perform the following three steps to adopt the UIInputViewAudioFeedback protocol:

在你的Xcode项目中，创建一个UIView类的子类。在头文件中，指示子类符合UIInputViewAudioFeedback协议，如下所示：
@interface KeyboardAccessoryView：UIView {
}

In your Xcode project, create a subclass of the UIView class. In the header file, indicate that the subclass conforms to the UIInputViewAudioFeedback protocol, as follows: @interface KeyboardAccessoryView : UIView { }

现在我我使用标准的UIViewController绑定到xib与我的所有按钮。我是：创建新文件，将其命名为UIView的子类，JUST所以我可以实现这个声音？这对我来说没有意义，如果这是非常业余的东西我道歉，但我从许多不同的地方学习。在此先感谢。

Now I am using the standard UIViewController tied to a xib with all my buttons. Am i to: Create New File, name it as a subclass of UIView, JUST so i can implement this sound? That doesn't make sense to me, and if this is really amateur stuff I apologize, but I'm learning from many different places. Thanks in advance.

推荐答案

您必须将自定义输入视图设置为 inputView 应该是第一个响应者的对象的属性（例如， UITextField 实例），以及 inputView （您的自定义输入视图）必须符合 UIInputViewAudioFeedback 协议。并实际发出咔嗒声： [[UIDevice currentDevice] playinputClick] 。

You have to set your custom input view as the inputView property of the object that is supposed to be the first responder (For example, a UITextField instance), and the inputView(your custom input view) must conform to the UIInputViewAudioFeedback protocol. And to actually play a click sound: [[UIDevice currentDevice] playinputClick].

例如：

@interface MyCalculatorDisplay : UIView
// ...
@end

@interface MyCustomKeyboard : UIView <UIInputViewAudioFeedback>
// ...
@end

// Then, somewhere in your controller:

MyCustomKeyboard *keyboard = [MyCustomKeyboard new];

MyCalculatorDisplay *display = [MyCalculatorDisplay new];

display.inputView = keyboard;
