I have 3 buttons one below the other.The requirement is , all should be centrally aligned.Also the dynamic contents should fit in these 3 buttons.Please help me with this issue. I have only a vague understanding about content hugging, compression resistance and intrinsic content size.Thank you very much in advance.

For iOS 9 and later:

Use UIStackView to embed all your buttons and set that stack view in centre of the view. For dynamic content, set stackView's heightConstraint greater than equal relation (>=).

For iOS 8 and earlier:

Just use UIView Instead of UIStackView. Rest of the things will be same.

Embed all UIBUttons within a UIStackView and set the stackViews properties to you needs.

To get the idea, see this answer.

Note: UIStackView is only available under iOS >= 9.
