添加子视图会在子视图和导航栏之间留下空白 [英] Adding subview leaves gap between subview and navigation bar

问题描述

我有一个包含在导航控制器中的视图的故事板，底部有一个UI标签栏。我动态添加子视图到此视图，但导航栏和子视图之间始终有一个空白行，显示为状态栏的宽度。在故事板上创建的每个子视图上，我将其模拟指标设置为将底部栏设置为选项卡栏，状态栏设置为无，顶部栏设置为导航栏。

I've got a storyboard with a view wrapped in a navigationcontroller, that has a UI tab bar at the bottom. I dynamically add sub views to this view, but there is always a blank line between the navigation bar and the subview that appears to be the width of a status bar. On each of the subviews that are created on the storyboard I have their Simulated Metrics set to have a bottom bar as a Tab Bar, status bar is set to none, and top bar is set to navigation bar.

下面是我添加子视图的代码：

Below is my code for adding the sub view:

    if(!self.homeViewController){
         self.homeViewController = [self.storyboardinstantiateViewControllerWithIdentifier:@"HomeView"];        
    }

    if(self.currentViewController != self.homeViewController)
    {            
        [self.view insertSubview:self.homeViewController.view belowSubview:self.tabBar];
        [self.currentViewController removeFromParentViewController];
    }

    self.currentViewController = self.homeViewController;

推荐答案

在Storyboard中定义的homeViewController，查看从NIB'属性到未命中（默认情况下已勾选）。这解决了我的差距问题。

On your homeViewController defined in Storyboard, set the 'Resize View From NIB' property to unticked (this is ticked by default). This cured the gap problem for me.
