POiOS layout; I'm not getting it
 

Note that there are some explanatory texts on larger screens.

    <p>Well, "not getting it" is too harsh; I've got it working in for what for me is a logical setup, but it does not seem to be what iOS deems logical. So I'm not getting something.</p> <p>Suppose I've got an app that shows two pieces of information; a date and a table. According to the MVC approach I've got three MVC at work here, one for the date, one for the table and one that takes both these MCVs and makes it into a screen, wiring them up.</p> <p>The master MVC knows how/where it wants to layout the two sub MVC's. Each detail MVC only takes care of its own childeren within the bounds that were specified by the master MVC. Something like:</p> <pre><code>- (void)loadView { MVC* mvc1 = [[MVC1 alloc] initwithFrame:...] [self.view addSubview:mvc1.view]; MVC* mvc2 = [[MVC2 alloc] initwithFrame:...] [self.view addSubview:mvc2.view]; } </code></pre> <p>If the above is logical (which is it for me) then I would expect any MVC class to have a constructor "initWithFrame". But an MVC does not, only view have this. </p> <p>Why? </p> <p>How would one correctly layout nested MVCs? (Naturally I do not have just these two, but the detail MVCs have sub MVCs again.)</p> <hr> <p>Thanks all for replying. I will study the links that were provided. </p> <p>Let me try to explain my issue one more time, hopefully to making it more clear. Do note that I already figured out that my view does not match iOS's, since I do not like where my code is going. </p> <p>Yes, I'm calling a UIViewController an "MVC", since it for me at the moment implements all aspects of a MVC; it has controller code and an embedded view, plus the controller usually also holds and provides the data (all TableView examples implement it like this). </p> <p>MVC can be present on many levels; basically a UITextField could (should?) be a MVC; there is a view, but also controller logic involved that you do not want to mix with other code. Encapsulation. For example: Java's Swing JTextField has a MVC. So does a JTable, JList, ... Multiple MVC patterns nested in other MVC's to build a whole screen.</p> <p>This what I expect when some platform says it uses the MVC pattern. So When I coded the table, I created a MVC and only send the loadData message with a date as the parameter to it. It needs to take care of the rest itself. I have a Detail MVC that can slide in; I then tell it the object it needs to show and it needs to take care of the rest itself. Encapsulation. </p> <p>So I have a lot of UIViewControllers with embedded UIViews. And that is not the way to do it...</p>

    1. COWhat is this **MVC** object you're talking about? Are you referring to UIViewControllers?

    2. COFirst, you only have 1 MVC. Unless the table references a CoreData dataset, and even then I'm sure you only have 1 MVC. You said it yourself = 1 View, with a date and table. Each of these 'subviews' can be controlled in the main Controller. [Check out this tutorial.](http://www.macresearch.org/cocoa_for_scientists_part_ix_mvc_is_not_the_motor_vehicle_commission)

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.
