1、u3d 发出的xcode工程 崩溃出现这种信息 Display::DisplayLinkItem::dispatch()

到AppController.mm 修改成这样

- (void) RepaintDisplayLink

{

//#if USE_DISPLAY_LINK_IF_AVAILABLE

//    [_displayLink setPaused: YES];

//

//    static const CFStringRef kTrackingRunLoopMode = CFStringRef(UITrackingRunLoopMode);

//    while (CFRunLoopRunInMode(kTrackingRunLoopMode, kInputProcessingTime, TRUE) == kCFRunLoopRunHandledSource)

//        ;

//

//    [_displayLink setPaused: NO];

//    [self Repaint];

//#endif

     [self Repaint];

}
