In Xcode 8.1, I can update for each view in the storyboard by clicking on the "Update Frames" button. But I want to update all views, how I can do that?
回答1:
It seems to update the frames hierarchically. If you select the main view or even the view controller and press the button, it will update frames for all child views.
回答2:
They added one standalone button to the leftmost side in the constraints controls (it looks like a refresh button). And you can also look for "Update Frames", from the toolbar and selecting Editor -> Resolve Auto Layout Issues -> Update Frames if you want you can select "Apply to all views in container" as before.. for you reference attaching screenshots.

If I understand you right you update frames when you have warnings about misplaced views. In this case, you can simply check the "Apply for all views in container" checkbox at the bottom of popup (which appears when you try to solve your warnings in the Document Outline) before pressing "Update Frames"
