iOS view visibility gone

by

As I have worked on both iOS & Android, You need to play with constraint outlet in ios to achieve Android functioning. iOS Does not support automatically like Android native support on visibility GONE & VISIBLE

You need to hook the outlet of particular constraint(it may vertical/horizontal/height) you need to set it to 0 & need to manage your UI.

To Hide:

self.viewYourConstraint.constant = 0
self.yourView.hidden = true
self.view.layoutIfNeeded()

To Show:

self.viewYourConstraint.constant = 100//your constant value
self.yourView.hidden = false
self.view.layoutIfNeeded()

Note: If other constraints will be affected because of the update to the constraint above, the following must also need to be called:

self.yourView.setNeedsUpdateConstraints()
