I want to inject touch event in iPhone. I get the coordinates of touch event via network socket. GSSendEvent seems to be good choice. However, it needs GSEventRecord as one of the inputs.
Does anyone know how to prepare GSEventRecord? I prepared it based on some examples but the app crashes after GSSendEvent call.
Appreciate any help.
-(void) handleMouseEventAtPoint:(CGPoint) point
{
static mach_port_t port_;
// structure of touch GSEvent
struct GSTouchEvent {
GSEventRecord record;
GSHandInfo handInfo;
} ;
struct GSTouchEvent *touchEvent = (struct GSTouchEvent *) malloc(sizeof(struct GSTouchEvent));
bzero(touchEvent, sizeof(touchEvent));
// set up GSEvent
touchEvent->record.type = kGSEventHand;
touchEvent->record.windowLocation = point;
touchEvent->record.timestamp = GSCurrentEventTimestamp();
touchEvent->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo);
touchEvent->handInfo.type = getHandInfoType(0, 1);
touchEvent->handInfo.pathInfosCount = 1;
bzero(&touchEvent->handInfo.pathInfos[0], sizeof(GSPathInfo));
touchEvent->handInfo.pathInfos[0].pathIndex = 1;
touchEvent->handInfo.pathInfos[0].pathIdentity = 2;
touchEvent->handInfo.pathInfos[0].pathProximity = 1 ? 0x03 : 0x00;
touchEvent->handInfo.pathInfos[0].pathLocation = point;
port_ = GSGetPurpleSystemEventPort();
GSSendEvent((GSEventRecord*)touchEvent ,port_);
}
static GSHandInfoType getHandInfoType(int touch_before, int touch_now){
if (!touch_before) {
return (GSHandInfoType) kGSHandInfoType2TouchDown;
}
if (touch_now) {
return (GSHandInfoType) kGSHandInfoType2TouchChange;
}
return (GSHandInfoType) kGSHandInfoType2TouchFinal;
}
