In my application, a NSDocument subclass mission-critical hardware – users really don’t want to close a document by accident! So, I’ve implemented canCloseDocumentWithDelegate… to show an NSAlert and ask before closing. I am now trying to implement this same thing in an application written in Swift. Since the answer comes asynchronously, the “should close” result is passed to a callback on a delegate, and not simply returned. In the documentation for -canCloseDocumentWithDelegate:shouldCloseSelector:contextInfo: , it says: The shouldCloseSelector callback method should have the following

I am new to Swift, and I'm trying to make a score collected program for Mac OS X. I do know about Swift programming on iOS, but I don't know that much about OS X Swift. So I wrote a program for OS X. I almost finished it, but i want to know how to make alert controller in mac using swift. I know how to do it on iso but i don't know how to do it on OS X and also i want to know how to use .isEmpty in OS X. import Cocoa class ViewController: NSViewController { @IBOutlet var Maths: NSTextField! = NSTextField() @IBOutlet var Science: NSTextField! = NSTextField() @IBOutlet var English: NSTextField!

Lets say I display a window like so: [[TBAddTaskWindowController new] showWindow:self]; Where is the TBAddTaskWindowController object meant to be released? Is the generic solution to call [self release] in windowWillClose? It doesn't feel right to have any other object "own" the window, because it's meant to exist until the user closes it. The same code that instantiated the window controller by sending the new message to the class, just the same as if it had done it by alloc and init messages. Peter N Lewis Yes, a common way to do release the window controller is with: - (void)windowWillClose

I am working on Xcode 6.1.1 on OSX 10.10. I am trying out storyboards for Mac apps. I have a NSTabViewController using the new NSTabViewControllerTabStyleToolbar tabStyle and it is set as the default view controller for the window controller. How do I make my window resize according to the current selected view controller? Is it possible to do entirely in Interface Builder? Here is what my storyboard looks like: The auto layout answer is half of it. You need to set the preferredContentSize in your ViewController for each tab to the fitting size (if you wanted the tab to size to the smallest

NSOutlineView is a subclass of NSTableView . And currently, NSTableView supports two implementations. Cell-based. View-based. To make OSX 10.8 Finder style side bar ( with automatic gray Icon styling ), need to use view-based table view with source-list highlight style. With NIBs, this is typical job. Nothing hard. (see SidebarDemo ) But I want to avoid any NIBs or Interface Builder. I want make the side bar purely programmatically. In this case, I have big problem. AFAIK, there's no way to supply prototype view for specific cell. When I open .xib file, I see <tableColumn> is containing

I have some submenu inserted as Window item submenu of Main Menu I have an instance of my object (let's assume its class name is MenuController) inherited from NSObject and supports 2 from NSMenuDelegate methods: – numberOfItemsInMenu: – menu:updateItem:atIndex:shouldCancel: This instance added as Blue-Object into NIB for awaking at runtime Object from steps 2-3 configured as delegate for submenu (step 1) Now, I can provide submenu content in runtime. Next, I do following: I can add new items or remove old from an array (inside MenuController which contains menu titles) that mapped to real
