<p>I wanted to know is it possible to capture the exact keyboard key press time and release time in an iOS application development? </p>

<p>For example, let's say I type "<code>Hello</code>". I'd like to know the <code>H</code>-Key pressed time and release time, then <code>E</code>, <code>L</code> etc. I think the answer will be in microseconds but that is what I want.</p>

<p>Any help would be really useful. </p>
