iOS11.0 contentInsetAdjustmentBehavior改变的是 adjustContentInset 而不是 contentInset

 //设置不透明
     self.navigationController.navigationBar.translucent = NO;
     self.tabBarController.tabBar.translucent = NO;
     
     当navBar和 tabBar 透明时候，extendedLayoutIncludesOpaqueBars无影响，
       self.view.frame =  {{0, 0}, {375, 667}}
     当navBar或 tabBar 不透明时候：
     NO，UIRectEdgeAll：self.view.frame = {{0, 64}, {375, 554}}
     YES，UIRectEdgeAll：self.view.frame = {{0, 0}, {375, 667}}
