使用GSEvent发送触摸事件，但它是无效的

我的代码是通过GSEvent向我的应用程序发送触摸事件，通过GSCopyPurpleSystemEventPort（）获取mach_port_t。

在ApplicationDidFinishLaunch：选项已经完成后，发送function启动。该应用程序是UIControlView应用程序。

代码如下：

void handleMouseEventAtPoint(CGPoint point, int buttons) { // NOTE: Must store button state for comparision, port for // mouse dragging and button up static int buttons_; static mach_port_t port_; int diff = buttons_ ^ buttons; bool twas = ((buttons_ & 0x1) != 0); bool tis = ((buttons & 0x1) != 0); buttons_ = buttons; // Round point values to prevent subpixel coordinates point.x = roundf(point.x); point.y = roundf(point.y); // Check for mouse button events mach_port_t purple; if ((diff & 0x10) != 0) { // Simulate Headset button press struct GSEventRecord record; memset(&record, 0, sizeof(record)); record.type = (buttons & 0x4) != 0 ? kGSEventHeadsetButtonDown : kGSEventHeadsetButtonUp; record.timestamp = GSCurrentEventTimestamp(); FixRecord(&record); GSSendSystemEvent(&record); } if ((diff & buttonThree) != 0) { // Simulate Home button press struct GSEventRecord record; memset(&record, 0, sizeof(record)); record.type = (buttons & buttonThree) != 0 ? kGSEventMenuButtonDown : kGSEventMenuButtonUp; record.timestamp = GSCurrentEventTimestamp(); FixRecord(&record); GSSendSystemEvent(&record); } if ((diff & buttonTwo) != 0) { // Simulate Sleep/Wake button press struct GSEventRecord record; memset(&record, 0, sizeof(record)); record.type = (buttons & buttonTwo) != 0 ? kGSEventLockButtonDown : kGSEventLockButtonUp; record.timestamp = GSCurrentEventTimestamp(); FixRecord(&record); GSSendSystemEvent(&record); } if (twas != tis || tis) { // Main (left button) state changed, or was dragged struct { struct GSEventRecord record; struct { struct GSEventRecordInfo info; struct GSPathInfo path; } data; } event; memset(&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 = twas == tis ? kGSHandInfoTypeTouchDragged : tis ? kGSHandInfoTypeTouchDown : kGSHandInfoTypeTouchUp; event.data.info.handInfo._0x44 = 0x1; event.data.info.handInfo._0x48 = tis ? 0x1 : 0x0; event.data.info.pathPositions = 1; event.data.path.pathIndex = 0x01; event.data.path.pathIdentity = 0x02; event.data.path.pathProximity = tis ? 0x03 : 0x00; event.data.path.pathLocation = event.record.windowLocation; if (twas != tis && tis) { // Button down and was not down before port_ = 0; CAWindowServer *server; server = [CAWindowServer serverIfRunning]; char svrptrstr [255]; sprintf(svrptrstr, "%p", server); NSLog(@"One!"); if (server = [CAWindowServer serverIfRunning]) //if (true) { NSLog(@"Two!"); //NSArray *displays([server displays]); NSArray *displays = [server displays]; if (displays != nil && [displays count] != 0) { NSLog(@"Three!"); //CAWindowServer *display; if (CAWindowServerDisplay *display = [displays objectAtIndex:0]) { NSLog(@"Four!"); port_ = [display clientPortAtPosition:point]; } } } if (port_ == 0) { // Is SpringBoard if (purple == 0) { purple = GSGetPurpleSystemEventPort(); port_ = purple; } } } FixRecord(&event.record); GSSendEvent(&event.record, port_); NSLog(@"Event sent!"); //GSSendSystemEvent(&event.record); //GSSendEvent(&event.record, purple); } if (purple != 0 && PurpleAllocated) { mach_port_deallocate(mach_task_self(), purple); NSLog(@"Deallocated mach_port!"); } } 

但在越狱ipad2（iOS5.01）启动应用程序，没有任何点击结果，如果单击事件完成，debug.log将在那里。

谁能告诉我我错过了什么？

我在别的地方看过这个代码（我想这是一个将鼠标点击转换为iPhone / iPad的应用程序）。 这里的问题不是代码或端口，而是你发送的事件结构。 这是iOS 3.0的GSevent结构，不适用于iOS 5.0。 它不仅在结构上，而且在价值和标签上都发生了变化。 我build议接收UIEvents，将它们翻译成GSEvents并查看其内容。
