I have a application with a tab view when the user clicks in the menu for example "client data" I generate a tab programmaticaly. Now I want to subclass the tab view to add a close button for each NSTabviewitem. If you don't have an answer you could help with documentation or sample code
I know this question is ancient, but...
I spent some time trying to add buttons to NSTabViewItems with a custom subclass, and as far as I can tell it's not really possible. NSTabViewItem simply isn't customizable enough to do the job.
My suggestion is to take a look at chromium-tabs or perhaps PSMTabBarControl; they have a different appearance than standard NSTabViewItems, but provide out-of-the-box functionality for icons and close buttons.

Apologies in advance if this is answered but I genuinely couldn't find it. I'm trying to bring up the keyboard type on iPad which appears when pressing the "#+=" button. I've tried going through all the types on the docs and I'm sure that this wasn't successful. Am I missing something or does the user have to click this button every time?
Edit: this question was closed as "off-topic" because it didn't include code or ideas or what I've tried already... Therefore for a bit of extra detail, I used EVERY keyboard type that is available on the docs e.g.
theTextField.keyboardType = UIKeyboardTypeNumberPad;
This did not yield the results that I require, which is the keyboard plane that appears when you press the #+= button because I wanted users to go straight to that one.
Unfortunately, this is impossible. It's not a keyboard type you want, it's a keyboard plane. There is no public API to switch or in any way access the keyboard planes.
One solution could be to create your own keyboard with the symbols you want. Another solution would be to open the keyboard and then generate a touch event that will switch the keyboard plane. However, this would be complicated, non-portable and a bit dangerous.
You have no ability to affect the built-in keyboards.
You can however create your own custom input view which you would set on the inputView of your text editing view before you make it first responder. Then iOS will show this view instead.
Have a look at this project of mine which implemented a "Morse keyboard" (April Fool's joke), but demonstrates how to achieve a custom keyboard that still interacts with a text field as you'd expect. http://www.cocoanetics.com/2012/04/dtmorsekeyboard-tutorial/
I wonder if someone could help me please? I'm brand new to iOS and whilst I've been searching various sites for my answer, I'm afraid I haven't come across it yet but feel this could just be my naivety to the language so I apologise if this is a really simple thing...
I have a Tab Bar Controller with 3 views. On my first tab I have a button which when clicked, I want it to go to the 3rd tab (which is does). However, on the 3rd tab, I would like to insert a back button so that the user has the option of clicking back to go back to what is essentially the main menu of my application.
Can anyone tell me how I can do this please? I'm currently using storyboarding as I'm not very good with the language yet but any help would be greatly appreciated.
Thanks

You need to add a navigation bar to the view and set a bar button item with the action to change the tab.
Remember that a tab controller is standard across multiple apps, the user is use to tapping the tab to change the view rather than pressing buttons within the view.
It might be worth you looking into a UINavigationController
The first thing, you are implementing UITabBarController. you don't have to create a back button, because user can navigate between screens by tap on tab bar.
Second thing, you can use UINavigationController to manage you viewControllers,the Back button will automatically show when you push ViewController by method pushViewController:animated:
I'd like to customize my UIToolBar, so the centered button looks something similar to the check-in foursquare button.
I've seen a commercial source code called ALToolBar, wich is similar to the effect I want on my UIToolBar. So in resume, changing the height of a button, and the background of a specific button, if that is the right way to go.
I'm pretty new to iOS, but comfortable enough to dig ideas the community can bring on.
Thanks for your help.
One approach is to just write your own Tabbar/Toolbar instead of using the built-in classes. Subclass UIView and add UIButtons for each item, which you can then customize as you wish.
The downside to this approach is, you loose the "More" functionality, that allows you to drag-and-drop items into the Tabbar, but if you just have 5 or fewer items, that's fine.
How would make a Status Item when the actually button is clicked in the Menu Bar not in a drop down menu show or hide a window?
Sorry if this is a bit vague.
NSStatusItem supports the target/action mechanism like many other controls. I haven't used this myself -- I've only ever used an NSStatusItem with a menu attached -- so I don't know when the message is sent (i.e. when the mouse button is clicked or when it's released). If it doesn't do what you want by default, you would need a custom view like Daniel suggests.
To achieve this with NSStatusItem you need to create a custom view and replace the default NSStatusItem view by calling its "setView:" method.
You'll implement code in your custom view to react to mouse clicks by e.g. putting up a window. (You can use a button, or other standard views if it works best for you).
I'll warn you this is a bit tricky to get right. Lots of little nuances e.g. with getting the look of your custom view to look right in the menu bar. But this is the general approach you need to take if you want to override the default menu-prompting status item view.
I have an NSPopUpButton providing the NSMenu for a status item with a custom view. The popup button displays a list of links. When the user selects a link from the list, the link is displayed in the user's browser (in the background).
Naturally, the menu closes every time the user selects a link.
I would like to change this: I want the menu to stay open while the user clicks on various links, all of which can be opened in the background. The menu can then go away when the user clicks elsewhere.
How can this be accomplished? Should I subclass NSMenuItem and intercept the mouse clicks somehow? Overlay a transparent NSView on the popped-up menu and, again, intercept the clicks somehow? I make these suggestions blithely, but I would have trouble implementing either of these...pointers to the right methods for override would be appreciated.
Instead of using a menu, one might use a collapsible box.I have seen that in many apps ( also provided by Apple) , so I guess this is the recommended style guide for multiple selections.
The collapsible box expands when you click the disclosure button, and it gives free all items desired - like a tableview with checkboxes.
Views below this box must move down in this case, not to interfere with the box.
Clicking again on the disclosure button will shrink the box back to its origin. The effect is similar to closing a menu.
Usually you should not bend a control too far past it's original intent. Users expect pop up buttons to close after making a selection. I don't think you should, or can, force NSPopUpButtonCell to behave in this way. If you do, you'll be subclassing and modifying the control so heavily that it might change/break with a future version of Mac OS X. You'd also have to worry about the usability problem of users thinking the menu will close after making a selection.
You might consider writing you're own subclass of NSView to work like the menu button you're describing. After the user clicks on the button. You'll want to create a new NSWindow, with no border by using NSBorderlessWindowMask as the style mask. The content view of that window should be another custom view of yours that you implement the menu selection in.
