预览和模拟器上的自动布局看起来有所不同
[英]Autolayout on preview and simulator looks different
问题描述
Autolayout for landscape mode isn't working. 
横向模式的自动版式无法正常工作。 Here's what I see in storyboard (preview): 这是我在情节提要（预览）中看到的内容：

And here's simulator: 这是模拟器：

As you can see, toolbar is disappearing to somewhere off the screen. 如您所见，工具栏消失在屏幕之外。 I've tried both Top Space to Superview = Standart value and Top Space to Top Layout Guide = Standart value in toolbar's contraints, but got no result. 我在工具栏的Top Space to Superview = Standart value都尝试了Top Space to Superview = Standart value和“要使用Top Space to Top Layout Guide = Standart value ，但是没有结果。
PS In the portrait mode everything works good. PS在人像模式下，一切正常。

First of all change device in preview and set it to iPhone 5 and then check looking perfect or not.If not then try to set from Size inspector from Utility area. 首先在预览中更改设备并将其设置为iPhone 5，然后检查外观是否完美;如果不正确，请尝试从工具区域的尺寸检查器中进行设置。
If this doesn't work then try this. 如果这不起作用，请尝试此操作。 Delete Derived data of your project.Then run again. 删除项目的派生数据。然后再次运行。 Derived Data located at ~/Library/Developer/Xcode/DerivedData/(your app data) 派生数据位于〜/ Library / Developer / Xcode / DerivedData /（您的应用程序数据）
