  • Cocoa: Hide one application

    - by Craig
    Is it possible to hide one specific application using cocoa? I know you can hide all other applications using the following code [[NSWorkspace sharedWorkspace] performSelectorOnMainThread:@selector(hideOtherApplications) withObject:NULL waitUntilDone:NO]; But is it possible to hide just one specific application say Safari for example?

  • Line smoothing in Cocoa Touch

    - by Sam Kaplan
    How would I smooth a line (UIBeizerPath) or a set of points? Right now it draws it jagged. I read about spline interpolation, could anyone point me to an implementation of this in cocoa or C or give me an alternate line smoothing algorithm.

  • NSFetchedResultsController Mac OSX COCOA equivalent

    - by Lukasz
    Hi! I am porting some Core data code from iPhone to Mac OS X. PRoblem is that CoreData Framework on Mac OS X does not have NSFetchedResultsController.h nor NSFetchedResultsControllerDelagete protocol declared. At least I am not able to force COCOA application to see this class even if I drag Core Framework from iPhone project to link with Mac Application? Anyone faced this problem?

  • Write Secure Cocoa Code

    - by happyCoding25
    Hello, Im making an application in cocoa and wanted to see if some strings in it were easily accessible so I ran OTX on it and sadly all of my code was found. Is there a method I can use to make my code more "secure" or at least encrypt/hide the strings? The reason I want to encrypt the string is it's a password for a server. I don'd need it really secure I just don't want the password to be so easy to find. Thanks for any help

  • Cocoa: Creating a Window with a Variable Number of Interface Elements

    - by Rui Pacheco
    Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?

  • Cocoa: How to make table view draw custom views in each cell

    - by Inso Reiges
    Hello, I am learning Cocoa and trying to create an application for Mac that displays a simple book list. Each book is an NSView with its cover image, title and author. I want to present this list as a NSTableView with a single column and a book view in each cell. However i can't yet figure out how to display a custom view inside a table cell in interface builder or programmatically. Any tips would be very appreciated :) Inso.

  • Change color of title bar in cocoa

    - by Nano8Blazex
    This must have been asked before, but after Googling I still can't find the answer. How do you change the color of the title bar (The bar that you can click and drag around with the close, minimize and maximize buttons) to a different color than the default gray in Cocoa?

  • Cocoa Core data filename?

    - by RW
    I followed Apple's example for creating a managed object which btw was great... http://developer.apple.com/cocoa/coredatatutorial/index.html However I now want to know what "name" (filename) the user saved his data as. Does anyone know how to pull the filename from the core data object. something like this would be great... NSLog (@"the filename is %@", [coreData filename]); Any ideas?

  • Working through exercises in "Cocoa Programming for Mac OS X" - I'm stumped

    - by Zigrivers
    I've been working through the exercises in a book recommended here on stackoverflow, however I've run into a problem and after three days of banging my head on the wall, I think I need some help. I'm working through the "Speakline" exercise where we add a TableView to the interface and the table will display the "voices" that you can choose for the text to speech aspect of the program. I am having two problems that I can't seem to get to the bottom of: I get the following error: * Illegal NSTableView data source (). Must implement numberOfRowsInTableView: and tableView:objectValueForTableColumn:row: The tableView that is supposed to display the voices comes up blank I have a feeling that both of these problems are related. I'm including my interface code here: #import <Cocoa/Cocoa.h> @interface AppController : NSObject <NSSpeechSynthesizerDelegate, NSTableViewDelegate> { IBOutlet NSTextField *textField; NSSpeechSynthesizer *speechSynth; IBOutlet NSButton *stopButton; IBOutlet NSButton *startButton; IBOutlet NSTableView *tableView; NSArray *voiceList; } - (IBAction)sayIt:(id)sender; - (IBAction)stopIt:(id)sender; @end And my implementation code here: #import "AppController.h" @implementation AppController - (id)init { [super init]; //Log to help me understand what is happening NSLog(@"init"); speechSynth = [[NSSpeechSynthesizer alloc] initWithVoice:nil]; [speechSynth setDelegate:self]; voiceList = [[NSSpeechSynthesizer availableVoices] retain]; return self; } - (IBAction)sayIt:(id)sender { NSString *string = [[textField stringValue] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; //Is the string zero-length? if([string length] == 0) { NSLog(@"String from %@ is a string with a length of %d.", textField, [string length]); [speechSynth startSpeakingString:@"Please enter a phrase first."]; } [speechSynth startSpeakingString:string]; NSLog(@"Started to say: %@", string); [stopButton setEnabled:YES]; [startButton setEnabled:NO]; } - (IBAction)stopIt:(id)sender { NSLog(@"Stopping..."); [speechSynth stopSpeaking]; } - (void) speechSynthesizer:(NSSpeechSynthesizer *)sender didFinishSpeaking:(BOOL)complete { NSLog(@"Complete = %d", complete); [stopButton setEnabled:NO]; [startButton setEnabled:YES]; } - (NSInteger)numberOfRowsInTableView:(NSTableView *)aTableView { return [voiceList count]; } - (id)tableView: (NSTableView *)tv objecValueForTableColumn: (NSTableColumn *)tableColumn row:(NSInteger)row { NSString *v = [voiceList objectAtIndex:row]; NSLog(@"v = %@",v); NSDictionary *dict = [NSSpeechSynthesizer attributesForVoice:v]; return [dict objectForKey:NSVoiceName]; } /* - (BOOL)respondsToSelector:(SEL)aSelector { NSString *methodName = NSStringFromSelector(aSelector); NSLog(@"respondsToSelector: %@", methodName); return [super respondsToSelector:aSelector]; } */ @end Hopefully, you guys can see something obvious that I've missed. Thank you!

  • Cocoa equivalent of diskEvt/kEventClassVolume?

    - by tewha
    We have a drop-down menu of volumes in our UI, and I'd like to update it when a new disk is mounted. In the Classic days, this would involve watching for a diskEvt event. In Carbon, I think this was kEventClassVolume. What's the Cocoa equivalent? (A pointer into Apple's documentation on this would satisfy the question. I've been unable to find anything!)

  • Cocoa JSON - Check whether array or dictionary

    - by Craig
    Hi, I am using the Cocoa JSON framework ( http://code.google.com/p/json-framework/ ) to communicate with an API. The problem is that the API returns a dictionary if there is an error but returns an array of the results if it works. Is there a good way to detect if the JSONValue is an array or a dictionary? Thanks.
