ios - 如何记录 IOS 中的每个用户交互

Question

我想通过 NSLog 记录 IOS 上的每个用户交互， 然后可能添加文件名、方法名和行号。

通常我希望看到这样的东西:

UI Front-most view controller: MYViewController (no title)
Interaction Action [MyViewController showMenu] by sender UIBarButtonItem

这是否可能使用 Objective-C。我不想更改每个文件，而是希望调用一些全局方法。我更愿意在 ApplicationDelegate 类中执行此操作。

有些地方你理解错了。 UIBarButtonItem never 是发件人，因为它的类是 NSObject不是UIView . UIBarButtonItem无法接收触摸，当我们点击一​​个条形项时接收触摸是一个UINavigationButton (私有(private)类(class))。

如果您想在用户点击 View 时记录每个用户交互，我有适合您的解决方案。

• 创建 UIWindow 的子类(调用 CustomWindow)。
• 覆盖 sendEvent UIWindow的方法|捕捉用户交互，检查并记录其中的交互。
• 内部didFinishLaunchingWithOptions AppDelegate的方法| , 替换默认 window带有窗口的类型为 CustomWindow .

这是我的 CustomWindow记录用户与控件事件的交互 UIControlEventTouchUpInSide的 UIControl类。

@implementation CustomWindow

- (void)sendEvent:(UIEvent *)event {
  UITouch *touch = [[event allTouches] anyObject];

  switch ([touch phase]) {
    case UITouchPhaseBegan:
    {
      NSLog(@"Touch Began");
    }
      break;
    case UITouchPhaseMoved:
      NSLog(@"Touch Move");
      break;
    case UITouchPhaseEnded:
    {
      NSLog(@"Touch End");
      // Check if touch ends inside view (UIControlEventTouchUpInSide)
      if (CGRectContainsPoint(CGRectMake(0, 0, touch.view.frame.size.width, touch.view.frame.size.height), [touch locationInView:touch.view])) {

        // Only log info of UIControl objects
        if ([touch.view isKindOfClass:[UIControl class]]) {
          [self logViewInfo:(UIControl *)touch.view];
        }
      }
    }
      break;
    case UITouchPhaseCancelled:
      NSLog(@"Touch Cancelled");
      break;
    default:
      break;
  }
  [super sendEvent:event];
}

- (void)logViewInfo:(UIControl *)clickedButton {
  NSString *frontMostViewcontrollerClassName = NSStringFromClass(self.topViewController.class);
  NSString *targetClassName = NSStringFromClass([[clickedButton.allTargets anyObject] class]);
  NSString *selectorName =[[clickedButton actionsForTarget:[clickedButton.allTargets anyObject] forControlEvent:UIControlEventTouchUpInside] firstObject];
  NSString *senderClassName = NSStringFromClass(clickedButton.class);

  NSLog(@"UI Front-most view controller: %@\nInteraction Action [%@ %@] by sender %@ control event UIControlEventTouchUpInSide", frontMostViewcontrollerClassName, targetClassName, selectorName, senderClassName);
}

- (UIViewController*)topViewController {
  return [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
}

- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)viewController {
  if ([viewController isKindOfClass:[UITabBarController class]]) {
    UITabBarController* tabBarController = (UITabBarController*)viewController;
    return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
  } else if ([viewController isKindOfClass:[UINavigationController class]]) {
    UINavigationController* navContObj = (UINavigationController*)viewController;
    return [self topViewControllerWithRootViewController:navContObj.visibleViewController];
  } else if (viewController.presentedViewController && !viewController.presentedViewController.isBeingDismissed) {
    UIViewController* presentedViewController = viewController.presentedViewController;
    return [self topViewControllerWithRootViewController:presentedViewController];
  }
  else {
    for (UIView *view in [viewController.view subviews])
    {
      id subViewController = [view nextResponder];
      if ( subViewController && [subViewController isKindOfClass:[UIViewController class]])
      {
        if ([(UIViewController *)subViewController presentedViewController]  && ![subViewController presentedViewController].isBeingDismissed) {
          return [self topViewControllerWithRootViewController:[(UIViewController *)subViewController presentedViewController]];
        }
      }
    }
    return viewController;
  }
}
