Difference between Modal and Push segue in storyboards?

A push Segue is adding another VC to the navigation stack. This assumes that VC that originates the push is part of the same navigation controller that the VC that is being added to the stack belongs to. Memory management is not an issue with navigation controllers and a deep stack.

As long as you are taking care of objects you might be passing from one VC to another, the compiler will take care of the navigation stack. See the image for a visual indication.

Modal segue can be created by simply ctrl-click and dragging to destination but when I do that with the push my app crashes. I am pushing from a button to a navigationcontroller that has a UIViewController.

As long as you are taking care of objects you might be passing from one VC to another, the compiler will take care of the navigation stack. See the image for a visual indication: A modal Segue is just one VC presenting another VC modally. The VC's don't have to be part of a navigation controller and the VC being presented modally is generally considered to be a "child" of the presenting (parent) VC.

The modally presented VC is usually sans any navigation bars or tab bars. The presenting VC is also responsible for dismissing the modal VC it created and presented. Hope this helps.

EIJay thanks for the great explanation. One more question when do I have to use the modal and when to use the push segue? – Gaurav_soni Feb 22 at 12:11 Generally, when you want to show a detail view of a summary view, use a navigation controller and Push Segues.

If the "parent" view doesn't really relate as far as data is concerned to the "child" view, then use a modal. A good example for a modal view would be a Login view. The Login view doesn't really have any relationship as far as data is concerned to the "parent" view.

– ElJay Feb 22 at 13:12 Can a modal view controller call another modal view controller? – T.J. Feb 22 at 14:39.

The push view must be builded in a navigation controller. Click on your master view, then in the file bar choose EDITOR->embed in->navigation controller.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
