[iOS]我可以在代码上更改自由格式UIViewController的大小吗？

Question

I want to change the size of UIViewController whose size has already set in storyboard as freeform . I need to remove some subview s after I get a certain result from a server. Originally the size is 320x750 but it sometimes will be reduced to 320x500.

I use autolayout.

Any suggestions?

Answer 1

I would remove autolayout and then use

   setPreferredContentSize:(CGSize)

If you want to keep autolayout, you'll have to programatically add constraints.
