The method intrinsicContentSize in NSView returns what the view itself thinks of as its intrinsic content size. NSTextField calculates this without considering the wraps property of its cell, so it will report the dimensions of the text if laid out in on a single line. Hence, a custom subclass of NSTextField can override this method … Read more
You use it when you want to execute a block and wait for the results. One example of this is the pattern where you’re using a dispatch queue instead of locks for synchronization. For example, assume you have a shared NSMutableArray a, with access mediated by dispatch queue q. A background thread might be appending … Read more
Mike Lee has an implementation of the flip effect for which he has released some sample code. (Unfortunately, this is no longer available online, but Drew McCormack built off of that in his own implementation.) It appears that he grabs the layers for the “background” and “foreground” views to be swapped, uses a CATransform3D to … Read more
Here are some specific implementations and details, note that proc->kp_proc.p_comm has a character length limit that’s why I’m implemented infoForPID: instead Cocoa : [NSWorkspace launchedApplications] (10.2+ , deprecated in 10.7, very limited process listing) [NSWorkspace runningApplications] (10.6+ , less limited process listing but still not including daemon processes) Carbon : – (NSArray*)getCarbonProcessList { NSMutableArray *ret … Read more
It’s actually much simpler and you won’t need private API. Make the root view of your view controller a custom class @implementation MyPopoverRootView -(void)viewDidMoveToWindow { NSView * aFrameView = [[self.window contentView] superview]; MyPopoverBackgroundView * aBGView =[[MyPopoverBackgroundView alloc] initWithFrame:aFrameView.bounds]; aBGView.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable; [aFrameView addSubview:aBGView positioned:NSWindowBelow relativeTo:aFrameView]; [super viewDidMoveToWindow]; } @end Your background view just … Read more
To launch an application : [[NSWorkspace sharedWorkspace] launchApplication:@”/Applications/Safari.app”]; To activate an app : NSRunningApplication* app = [NSRunningApplication runningApplicationWithProcessIdentifier: PID]; [app activateWithOptions: NSApplicationActivateAllWindows]; // or NSArray* apps = [NSRunningApplication runningApplicationsWithBundleIdentifier:@”com.bla.blah”]; [(NSRunningApplication*)[apps objectAtIndex:0] activateWithOptions: NSApplicationActivateAllWindows];
Matt Gallagher has written a pretty informative article on Cocoa’s collection classes, along with a couple of benchmarks (with & without initWithCapacity:, as well as cross class comparisons) http://cocoawithlove.com/2008/08/nsarray-or-nsset-nsdictionary-or.html His test (source available) for an NSMutableArray of length 1,000,000 took 0.582256sec without capacity and just 0.572139sec with capacity. Test | Time [NSMutableArray array] | 0.582256 … Read more
The other answers didn’t work for multiple lines. Therefore I initially continued using the undocumented cFlags.vCentered property, but that caused my app to be rejected from the app store. I ended up using a modified version of Matt Bell’s solution that works for multiple lines, word wrapping, and a truncated last line: -(void)drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView … Read more
Here’s a class I created to perform a “deep copy” of managed objects: attributes and relationships. Note that this does not check against loops in the object graph. (Thanks Jaanus for the starting off point…) @interface ManagedObjectCloner : NSObject { } +(NSManagedObject *)clone:(NSManagedObject *)source inContext:(NSManagedObjectContext *)context; @end @implementation ManagedObjectCloner +(NSManagedObject *) clone:(NSManagedObject *)source inContext:(NSManagedObjectContext *)context{ … Read more
You need to escape the special characters to make it work properly. Something like: [NSURL URLWithString:[googlSearchString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
