    <p>in my app, there is a chatting service. when the user wants to message someone new, he press on "new chat" and a Table View Controller is shown to select from the list of friends. i'm using unwind segues in order to go back to the previous view controller and share the data between the two view controllers (mainly the data will be the friend to have a chat with). the unwind segue works perfectly, however in my app, when the user goes back to the main VC, i fire a new segue in order to go to another VC directly where the user has the chat; and this isn't working. All segues are well connected and i tried NsLog in every corner and it's entering there and even the prepareForSegue: is being accessed. i tried putting an NsTimer, thought there might be some technical conflict, and it didn't work. i change the segue to the chat VC to a modal and now it's giving me this error:</p> <blockquote> <p>Warning: Attempt to present on whose view is not in the window hierarchy!</p> </blockquote> <p>i can access this VC in other ways and it's in the hierarchy. my questions are: what could be wrong? does unwind segues alter the windows hierarchies ? </p> <p>PICTURE: <img src="https://i.stack.imgur.com/bIvGI.png" alt="enter image description here"></p> <p>to present the problem more visually, the main VC i'm talking about is on the bottom left connected to a navigation view controller. when a user presses new chat, the two VC on the top right are presented (one to choose between friends or group, the other to show the friends/ groups). so when a friend is selected for say from the top right VC i should unwind segue to the main VC. as you can see from the main VC there is other segues. non of them can work if i do unwind segue and they do work if i operate normally.</p>

    1. COpure guess here considering we cant see your storyboard or your code, but most likely you are trying to present the view controller from a view which the unwind segue has dismissed, can you show us any code or anything?

    2. CO@JAManfredi okay i added a picture and an explanation. i guess code is minimal and wouldn't do any difference. hope it's clear.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
