When printing a view in Cocoa how can I print only one view of a NSSplitView, when is displaying all of its subviews?
In the picture below I would like to print the Header View and the SubView1, not SubView2.
I know that I could create a new view for printing, but I would like to know if this is possible with what I got.
Thanks
PS: I'm using storyboards

I have a view controller contains a table view that displays list of items. Each item could contains list of items (or could be a leaf).
To drilldow the list items, I would like to create a show/push segue, kinda in recursively way, but I seem not able to draw the manual segue to the view controller itself?
Is it supported?
I was playing around with it just after leaving that first comment - I don't think you can have a manual segue to the same view controller!
The best thing to do would be to give that view controller a storyboard identifier (e.g Selection and then create an instance of that view controller with (in Swift):
let subCategoryVC = storyboard.instantiateViewControllerWithIdentifier("Selection") as! SelectionViewController
or in Objective-C:
SelectionViewController *subCategoryVC = (SelectionViewController *) [self.storyboard instantiateViewControllerWithIdentifier:#"Selection"];
(Docs for UIStoryboard.instantiateViewControllerWithIdentifier:)
You could put that in your table view section method along with a manual segue to the leaf view controller.
(The code above assumes the view controller with the table view is called SelectionViewController!)
As Rich mentioned, this is probably not doable as for today. There are two workaround/solutions I can think of:
Instaniate the vc programatically from storyboard and programatically
use navigationController to push it. (I think this is what Rich was
talking about.)
Embed the View Controller in another Navigation Controller and draw
the manual segue to the Navigation Controller.
I choose the 2nd one just because it is very easy and more visual in storyboard. The first one should just work, too.
So what I want is I have two ViewControllers in my Storyboard, one is supposed to be displayed when the current pageControl page is 0, the other one is for page 1.
Let's say I have AViewController and BViewController, both are from the same class TestViewController. I have properties from both classes in my TestViewController.h file, so that works. It loads AViewController but when I try to display BViewController nothing happens. I know I can do this by using multiple View but that can be confusing so two ViewController in my Storyboard does seem like a good solution. What I've tried to display the view is adding it as a subview, i also set the frame programmatically and setHidden = false, i also created another view and sub viewed the table into the view and then this view into the original one but nothing has worked so far. Now I'm wondering is that even possible and how'd I do this?
I have a reasonably complicated UIView which contains several nested views which are displayed according to a variety of responses - all are laid out in a storyboard.
Is there a way to hide a view in the foreground to work on a view in the background? As its really fiddly selecting particular elements to arrange / style!?
I've been trying to figure out a nice way to do this, some function like hiding the view and its subviews from the storyboard (not from the actual application), but couldn't find anything.
This is not the nicest of ways but it is how I do it at the moment...
What I do is select the views I want to "hide" from the document outline and add a constant (screen width/height) value to its x/y origin value to push them out of the screen. I also change the document label for those views (Identity Inspector > Document > Label) to something like "Hidden" so I can later search for the "hidden" views from the document outline and put them back where they belong.
I have 2 work arounds.
A) Change the View Controllers size to freeform. Set its size to be really large so I can space out the views.
B) Use the sort order of the views Document Outline (lowest is front most) and add an image view (same as the view background) under the first view to block the others. Then delete it after finishing my edits.
or xcode developers could just simple add a design-visible checkbox for views and controls.... but ill take my rants somewhere else.
In xcode 7 you can do it from the storybord

Maybe this could help you :
Open your storyboard in the Finder and edit it with a simple text editor (not xcode).
You will see it's just a xml file.Look for the view you want to hide, and add hidden="YES" in the parameters list.
That's what I do on my own project.
In Xcode when you select your storyboard, you have a panel that displays all your view controllers and their hierarchy. If you change the order of the elements you change the background/foreground order.
You can add extra views to the scene dock.
These views get initiated along with the view controller, but are not added to the view controller's view hierarchy. You can reference them using IBOutlets.
e.g. I have a full screen loading view that I added to the scene dock instead of covering up the view controller in the storyboard. I can add the loading view to the view controller's view hierarchy in code:
#IBOutlet weak var loadingView: UIView!
...
loadingView.frame = view.bounds
loadingView.autoresizingMask = UIViewAutoresizing.FlexibleWidth.union(UIViewAutoresizing.FlexibleHeight)
view.addSubview(loadingView)

I'm just learning and playing with the apple Seismic XML example
http://developer.apple.com/library/ios/#samplecode/SeismicXML/Introduction/Intro.html
I've got most of it figured out, but the one area I can't get past is, if I want to remove the tableview controller and create a view controller populated with a tableview. I can get the tableview to appear fine, but no matter what I try I can never get it to populate.
In the viewdidload area I can setup the tableview, color the background, do whatever I want to do, but I seem to 'lose' control of it somehow.
In short, would someone please be able to give me the steps involved in correctly changing the tableviewcontroller to a viewcontroller with a tableview in the apple example?
Thank you.
Lian, you need to read the documentation on UITableViewController. http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/TableView_iPhone/AboutTableViewsiPhone/AboutTableViewsiPhone.html
I'm not sure what you mean by "remove the tableview controller and create a view controller populated with a tableview" or why you would want this configuration. If you're having trouble with populating the tableViewController, you just pass in the data, usually from an NSArray or NSDictionary in the cellForRowAtIndexPath method. You either need to select the UITableViewController template when you create the class file or include the UITableViewDataSource and UITableViewDelegate if you're adding a tableView to a ViewController.
If you mean you want to change the view controller on screen, then you're looking to pop to another view using the navigation controller.
I created a view Called ProgrammaView that appears when a row of a table is clicked.
This view has a UILabel, a UIImageView and a UITextView.
Now.
ProgrammaView's Outlets have to be changed by the parameter passed to a method of the view called iniz.
in this
image there is first the ProgrammaView.h and then the method iniz.
The problem is that the label and other stuff doesn't change!
I checked 3 million times that everything between the xib file and the controller is linked.
The trick to call iniz in the other viewcontrollers works well in other part of the program so i think is not that the problem.
Thank you in advance!
You need to call setNeedsDisplay to indicate that the view should be redrawn.
My understanding is that you start up and show view after that you update the values and expect the view to display new values.
You need to call setNeedsDisplay to indicate that the view should be redrawn. Try to add it at the end of your iniz method.
See apple doc.
