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}}
