    <p>I would like to achieve system-wide tap simulation on iOS, via a MobileSubstrate plugin. The idea is to be able to simulate touches (in a first time single touch, then multitouch) on a system-wide level, in iOS 5.1.1 .</p> <p>I've been successful in implementing <a href="http://cocoawithlove.com/2008/10/synthesizing-touch-event-on-iphone.html" rel="nofollow">this article</a> to simulate touches on a specific view, I now would like to be able to simulate them system-wide. </p> <p>I understand I should use the private MobileServices framework to do so, and I've <a href="https://github.com/kennytm/iphone-private-frameworks/blob/master/GraphicsServices/GSEvent.h" rel="nofollow">documented myself</a> on GSEvent (I've also looked at Veency &amp; MouseSupport sourcecodes). </p> <p>I tried to hook up a view to intercept UIEvents and look at the underlying structure :</p> <pre><code>-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ GSEventRef eventRef = (GSEventRef)[event performSelector:@selector( _gsEvent)]; GSEventRecord record = *_GSEventGetGSEventRecord(eventRef); &lt; breakpoint here to look at record &gt; } </code></pre> <p>and the result is extremely similar to the old (iOS 3) structure detailled above.</p> <p>I then tried to fire up those events myself (on a Standalone app, not a MS tweak for now) : </p> <pre><code>+(void)simulateTouchDown:(CGPoint)point{ point.x = roundf(point.x); point.y = roundf(point.y); GSEventRecord record; memset(&amp;record, 0, sizeof(record)); record.type = kGSEventHand; record.windowLocation = point; record.timestamp = GSCurrentEventTimestamp(); GSSendSystemEvent(&amp;record); } </code></pre> <p>Now, that doesn't work at all (doesn't crash either).</p> <p>Most codes (MouseSupport, Veency) look like this</p> <pre><code>// Create &amp; populate a GSEvent struct { struct GSEventRecord record; struct { struct GSEventRecordInfo info; struct GSPathInfo path; } data; } event; memset(&amp;event, 0, sizeof(event)); event.record.type = kGSEventHand; event.record.windowLocation = point; event.record.timestamp = GSCurrentEventTimestamp(); event.record.infoSize = sizeof(event.data); event.data.info.handInfo.type = kGSHandInfoTypeTouchDown; event.data.info.handInfo._0x44 = 0x1; event.data.info.handInfo._0x48 = 0x1; event.data.info.pathPositions = 1; event.data.path.pathIndex = 0x01; event.data.path.pathIdentity = 0x02; event.data.path.pathProximity = 0x00; event.data.path.pathLocation = event.record.windowLocation; GSSendSystemEvent(&amp;event.record); </code></pre> <p>Only :</p> <ul> <li>GSEventRecordInfo is unknown (and I can't find where it might be defined)</li> <li>I don't see the point of making a whole event to only pass the record</li> </ul> <p>Please someone who's been through this on iOS 5 guide me.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
