问题 I need to create a compiled framework for distribution to third parties. I am using cocoa-pods to handle my dependencies. In order to accomplish this, it would seem that that creating a dynamic linked framework is the best option, but I am not sure and open to suggestions. The steps I took are: I created a wrapper project to contain the framework target Inside the wrapper project I added a new target "Cocoa touch framework" - "MyFramework" All of the relevant code is added to the target Added

问题 I'm developing an app on MacOS X with Xcode5.1 and there's an action I want to trigger everytime the user opens or shows a NSWindowController all I found was windowDidLoad windowWillLoad awakeFromNib but nothing like in iOS: my methods... viewWillAppear viewDidAppear because even if I close an NSWindowController with [NSWindowController close]; if I open it again, it doesn't trigger my actions from windowDidLoad, windowDidAppear or awakeFromNib and now I need something like them, what's the

问题 How can I terminate another app that is running in cooca. Let's say I have iTunes running, and I type in quit in my app, it would quit itunes. "iTunes" is just an example, it could be anything the user wants. I can open any app from my application, but I want to know how to close any app running. thanks kevin 回答1: If you're running on Mac OS X 10.6, Snow Leopard, you can use the new NSRunningApplication terminate method. 回答2: AppleScript is a pretty high-level way to send a single Quit event.

问题 I'm creating a KVC/KVO-compliant mutable array on one of my objects the recommended way: @interface Factory { NSMutableArray *widgets; } - (NSArray *)widgets; - (void)insertObject:(id)obj inWidgetsAtIndex:(NSUInteger)idx; - (void)removeObjectFromWidgetsAtIndex:(NSUInteger)idx; @end Clearly this is a tricky thread-safety issue. In the insert and remove methods I'm locking around array access to prevent concurrent modification, as recommended. My question is, what is the proper way to implement

问题 I have an NSTableView which is bound to an NSArrayController. I would like to have one of the table columns showing the index of the table row. This is easy enough to do when you implement NSTableDataSource yourself but I can't figure it out with a bound table view. I guess I'm looking here for something like the @count key path which gives me the count of arrangedObjects (that is @index) but this is obviously missing. Two clarifications: The index that is shown in each row is the index of

问题 How could I read an environmental variable that a user has set? I'm new to desktop development on the Mac (cocoa), and I am building a little tool that I can use to access amazon's s3 service. I set my environmental variables in my .bash_profile, but I want this to work regardless of where the user entered it (.bashrc, .bash_profile or .profile etc). 回答1: Look at the environment method on a NSProcessInfo. It returns a NSDictionary of the environment so e.g. for PATH NSString* path = [[

问题 I tried to add a simple status menu to the status bar with swift but it will not be shown. with objective-c this worked: AppDelegate.h @interface AppDelegate : NSObject <NSApplicationDelegate> { IBOutlet NSMenu *statusMenu; NSStatusItem * statusItem; } @end AppDelegate.m @implementation AppDelegate - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { statusItem = [[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength]; [statusItem setMenu:statusMenu]

问题 I am wondering if there is a way to do this using Core Animation. Specifically, I am adding a sub-layer to a layer-backed custom NSView and setting its delegate to another custom NSView. That class's drawInRect method draws a single CGPath: - (void)drawInRect:(CGRect)rect inContext:(CGContextRef)context { CGContextSaveGState(context); CGContextSetLineWidth(context, 12); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, 0, 0); CGPathAddLineToPoint(path, NULL, rect

问题 I need to use NSPageController in some project but I have no idea how it works, does anybody have time for some simple tutorial to show me because the documentation isn't helping me. Forgot to mention: I'm working on Mac project ( NOT iOS ) 回答1: Simple NSPageController book mode tutorial Create new Cocoa Application -project. Open MainMenu.xib in interface builder and add Image Well and Label objects to your application window. Also add Page Controller object. Set Page Controller's view to
