So I want the ability to change the title of the UINavigationItem from within the app. To be more specific, I want to be able to tap the title on the navigation bar and have it go into edit mode; where I can type in a new title. Is there any way to do this?
It's quite possible and not very hard in fact. Here are the simple steps:
Navigation item allows for custom views in its title
Add a view with a label similar to that of the native navigation item
Add a transparent button (custom button) on top of the label
Add a hidden text field on top of the button
When the button is pressed, hide the label and show the text field - focus on the text field (becomeFirstResponder)
You are in editing mode: now track for "Return" key being pressed, and once that happens set your label text to what has been entered, resign first responder from the text field and hide it, then show the label
If you adjust all the properties of the UI components it will look like your navigation item supports inline editing!

How to display show/Hide button in highlight regular mode of NSOutlineView?
I have a grop item at the top of NSOutlineview. I try to display show/hide button in that group item, but I can't find any method to do it. The source list mode can display it but regular mode doesn't.
Is it possible to display show/hide button in highlight regular mode of NSOutlineview?
thanks for helping
This behavior is specific to the source list appearance. There is no public API for getting around this, as it's an intentional enforcement (on Apple's part) of standardized appearances. You could dig around in the headers to look for a way to "hotwire" things, but use of private API bars you from distributing your app through the App Store.
The easier (non-private-API-using) route is to create your own cell view with a borderless button with show/hide title. Use a mouse tracking area (see NSTrackingArea) on the cell view (the superview of your button) to set the button's alpha (via its animator) to fade the button in/out on mouse in/out. Your button would tell the outline view to expand/collapse its cell view's represented item (the easiest way would be to define an outlet to the button via your custom NSView cell view class and configure the button's target/action when the cell view is created for the item).
How can you add or replace a view within a view with code? I'm programming for OSX, not IOS.
I am using a drawer that utilizes a custom view. In the custom view I have two boxes, one with a custom set of icons that I want to stay static and another box that has the information related to that button. What I want to do is when a user clicks one of the buttons that the 2nd box view changes to reflect the info for that button.
For example, I have five buttons and the default 2nd box is "Info", if the user clicks the 2nd button in the first box view I want to change the 2nd box to be the "List" box instead while the 1st box with the buttons stays intact.
I'm not sure how this would impact constraints since while the first box is a fixed size, the 2nd box needs to be dynamic so that it fills in the "rest of the space" so that when the drawer size changes with the window size that the 2nd box is taking up the remaining real estate.
Thank you!
I have implemented such a scenario in the past using a tabless NSTabView, and an NSSegmentedControl (for the buttons). The NSTabView has it's -takeSelectedTabViewItemFromSender: action connected to the NSSegmentedControl, using Interface Builder.
In the Connections Inspector, this shows up like so:
This has the effect that the index of the selected NSTabViewItem in your NSTabView will correspond to the index of the selected segment in the NSSegmentedControl.
I would like to create a menu item with an embedded NSProgressIndicator, similar to the "Wi-Fi: Looking for Networks…" menu item of the Wi-Fi status menu:
I think that I will need to use the setView: method as discussed at: Views in Menu Items. However, when I call setView: and pass an NSProgressIndicator, only the NSProgressIndicator is displayed.
How can the custom menu item view be created to get a similar result as the "Wi-Fi: Looking for Networks…" menu item of the Wi-Fi status menu?
As noted in the document to which you linked:
A menu item with a view does not draw its title, state, font, or other standard drawing attributes, and assigns drawing responsibility entirely to the view.
So, if you want your menu item to look like a normal menu item plus some other stuff, your view has to draw the normal menu item features in addition to the other stuff. So, you could set the menu item's view to a custom view. The progress indicator would be one subview of that custom view, but you would need other subviews for the other features. For example, a text field for the text of the menu item and an image view for a state indicator (if your item shows state).
You'll have to draw highlighting as the item is selected or tracked. You'll also have to do mouse tracking. Apple has some sample code which demonstrates various parts of this:
MenuItemView
CustomMenus
GridMenu
How can i show toolbar with "Next" and "Previous" buttons on top of the keyboard on iPad like in ShareKit(when logging in)? I have many of text fields, and i need switching between this text fields by using toolbar buttons
Design your toolbar however you prefer, then set it to the InputAccessoryView property of the UITextField whose keyboard it should accompany. It will be automatically displayed above the keyboard whenever it appears.
how can I have a back button and another button both on the left side of the nav bar?
Do you also need the title? If not, you can simply place the button in the center area. Otherwise, if you also need the title, you will need to create a UIView with a label and a button in it and set that as the center view. You will have to set the label's text manually if the title of the view ever changes.
Or, if you don't care too much about the back button, you can create a button that looks like the back button and put your other button next to it in a parent view that you use as the left view. You would have to manually handle going back when pressing the back button, and unless you got an image that looks like the back button, your button would not have the arrow shape.
