1，修改main方法

int main(int argc, char * argv[]) {
    @autoreleasepool {
        return UIApplicationMain(argc, argv, NSStringFromClass([AppDelegate class]), NSStringFromClass([AppDelegate class]));
    }
}

2，让 AppDelegate继承自UIApplication，原来是继承自UIResponder

@interface AppDelegate : UIApplication <UIApplicationDelegate>

3，在AppDelegate中实现 sendEvent方法

- (void)sendEvent:(UIEvent *)event
{
    [super sendEvent:event];
    
    NSSet *allTouches = [event allTouches];
    if (allTouches.count > 0) {
        UITouchPhase phase = ((UITouch *)[allTouches anyObject]).phase;
        if (phase == UITouchPhaseBegan) {
            NSLog(@"TouchPhaseBegan");
        }
    }
}
