tabbar项大于5时,qmui_visibleViewControllerIfExist判断错误 #75

运行环境

• iOS 设备：iPhone / iPad / 模拟器
• 系统版本：iOS 10.x
• Xcode 版本：8.x
• QMUI iOS 版本：1.x.x

具体问题描述

当tab的item大于5,并且tab的selectedIndex大于等于5的时候,系统把子项强行放到了moreNavigationController,导致获取selectedViewController的navVC里面的viewControllers为0

• (UIViewController *)qmui_visibleViewControllerIfExist {

  if (self.presentedViewController) {
  return [self.presentedViewController qmui_visibleViewControllerIfExist];
  }

  if ([self isKindOfClass:[UINavigationController class]]) {
  return [((UINavigationController *)self).visibleViewController qmui_visibleViewControllerIfExist];
  }

  if ([self isKindOfClass:[UITabBarController class]]) {
  UITabBarController *tab = (UITabBarController *)self;
  if (tab.selectedIndex >= 4 && tab.customizableViewControllers.count > 5) {
  // 当tab的item大于5,并且tab的selectedIndex大于等于5的时候,系统把子项强行放到了moreNavigationController,导致获取selectedViewController的navVC里面的viewControllers为0
  return [tab.moreNavigationController qmui_visibleViewControllerIfExist];
  }else{
  return [((UITabBarController *)self).selectedViewController qmui_visibleViewControllerIfExist];
  }
  }

  if ([self qmui_isViewLoadedAndVisible]) {
  return self;
  } else {
  QMUILog(@"UIViewController (QMUI)", @"qmui_visibleViewControllerIfExist:，找不到可见的viewController。self = %@, self.view = %@, self.view.window = %@", self, [self isViewLoaded] ? self.view : nil, [self isViewLoaded] ? self.view.window : nil);
  return nil;
  }
  }
