问题描述
我想生成键盘的keydown和编程KEYUP事件。我目前使用CGPostKeyboardEvent要做到这一点，但是我正在寻找这样做的方式在一个较低的水平。我已经看过DDHidLib但不能想出一个办法来创建一个假的事件。谁能帮助？
I am trying to generate keyboard keydown and keyup events programmatically. I am currently using CGPostKeyboardEvent to do this, but I am searching for a way to do this at a lower level. I have looked at DDHidLib but could not figure out a way to create a fake event. Can anyone help?
更新：
由于weichsel的意见，我现在正在创建具有以下关键down事件：
update: Thanks to weichsel's advice I am now creating a key down event with the following:
CGEventRef e = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)52, true);
CGEventPost(kCGSessionEventTap, e);
CFRelease(e);

which I found here.
然而，我的问题仍然有效，所以我会详细一点。我想发送键presses来实现键捕获功能：
However, my problem still stands so I will elaborate a bit. The application (3rd party) that I would like to send keypresses to implements DDHidLib's key capturing function:
- (void) ddhidKeyboard: (DDHidKeyboard *) keyboard
keyDown: (unsigned) usageId;
和这永远不会使用当前的方法被调用。我的猜测是，与CGEventCreateKeyboardEvent下模拟的关键是在过高的水平，由ddhidKeyboard捕获：KEYDOWN。所以，我所要做的是在足够低的水平，这样它将被ddhidKeyboard识别创建keydown事件：KEYDOWN。
And this never gets called using the current method. My guess is that the key down simulated with CGEventCreateKeyboardEvent is at too high of a level to be captured by ddhidKeyboard:keyDown. So what I am trying to do is create the keydown event at a sufficiently low level such that it will be recognized by ddhidKeyboard:keyDown.
推荐答案
这有什么错Quartz事件服务？结果
我认为你是正确的轨道上，但你应该使用<$c$c>CGEventCreateKeyboardEvent而不是 CGPostKeyboardEvent ，因为后者是因为Mac OS X 10.6 pcated德$ P $。
What's wrong with Quartz Event Services?
I think you are on the right track, but you should use CGEventCreateKeyboardEvent instead of CGPostKeyboardEvent because the latter is deprecated since Mac OS X 10.6.
