如何在越狱设备上使用GSEvent模拟多点触摸？

我想模拟在越狱设备上的多点触摸事件，我尝试了GSEvent ，我不知道每个领域的结构，所以我只是假设每个pathInfo意味着一个手指信息，但没有效果，任何人都可以给我一些帮助？非常感谢你。

 typedef struct touch { int identity; int x; int y; GSHandInfoType type; } touch; static void sendTouches(touch touches[]) { if (touches_count<1) { return; } uint8_t touchEvent[sizeof(GSEventRecord) + sizeof(GSHandInfo) + sizeof(GSPathInfo)*touches_count]; // structure of touch GSEvent struct GSTouchEvent { GSEventRecord record; GSHandInfo handInfo; } * event = (struct GSTouchEvent*) &touchEvent; bzero(touchEvent, sizeof(touchEvent)); // set up GSEvent event->record.type = kGSEventHand; event->record.subtype = kGSEventSubTypeUnknown; event->record.windowLocation = CGPointMake(touches[0].x, touches[0].y); event->record.timestamp = GSCurrentEventTimestamp(); event->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo); event->handInfo.type = touches[0].type; event->handInfo.x52 = touches_count; event->handInfo.pathInfosCount = touches_count; for (int i=0; i<touches_count; i++) { bzero(&event->handInfo.pathInfos[i], sizeof(GSPathInfo)); event->handInfo.pathInfos[i].pathIndex = 1; event->handInfo.pathInfos[i].pathIdentity = 2; event->handInfo.pathInfos[i].pathProximity = (touches[i].x == kGSHandInfoTypeTouchDown || touches[i].x == kGSHandInfoTypeTouchDragged || touches[i].x == kGSHandInfoTypeTouchMoved) ? 0x03 : 0x00;; event->handInfo.pathInfos[i].pathLocation = CGPointMake(touches[i].x, touches[i].y); } mach_port_t port = (mach_port_t)getFrontMostAppPort(); GSSendEvent((GSEventRecord *)event, port); } int test() { // simulate two fingers touch from the center to two sides of the screen. struct touch touchesDown[2] = [{0, 140, 200, kGSHandInfoTypeTouchDown}, {1, 160, 200, kGSHandInfoTypeTouchDown}]; struct touch touchesMove[2] = [{0, 40, 200, kGSHandInfoTypeTouchDragged}, {1, 300, 200, kGSHandInfoTypeTouchDragged}]; struct touch touchesUp[2] = [{0, 40, 200, kGSHandInfoTypeTouchUp}, {1, 300, 200, kGSHandInfoTypeTouchUp}]; sendTouches(touchesDown); usleep(20000); sendTouches(touchesMove); usleep(20000); sendTouches(touchesUp); }
