如何以编程方式自动使父视图适合其子视图？

Question

I'm new to IOS development and I'm trying to make one of my parent view become automatically fit to its child views.

For example the picture above have a red circle which indicates a blank space I'm going to adjust the text upward so it fulfill the spaces and I also want that the container of all the text will automatically adjust its height to fit for its content.

Thanks.

Answer 1

You need to override the willMoveToSuperView and didMoveToSuperView

Check the answer here iPhone/iOS: Will there be called any method if a UIView is added as a subview

You can then adjust the view according to its super view. However, using auto layouts is a much preferred way.

Answer 2

You Should do one thing.
First alloc your parent view and give it a frame then, when your child view will alloc and it has a frame then set your parent view's frame one's again.

So, when your child view will appear then your parent view's frame will automatically set.

Hope this helps...
