  • How to select one NSCell in an NSTableView?

    - by Paperflyer
    I have a small NSTableView with a checkbox. Whenever the checkbox is not checked, I want one of the adjacent NSCells to be grayed out and inaccessible. However, I can't figure out how to address only one specific cell. -dataCellForRow of NSTableColumn always changes the template cell for the whole table column. How can I access one single cell?

  • How can I launch QuickTime from my app?

    - by Sheehan Alam
    I am trying to load a video from the web, but am having trouble getting it to appear in QuickTime. I can only hear the audio. I would like it to launch QuickTime. - (void)loadView { NSURL *movieURL = [NSURL URLWithString:@"http://movies.apple.com/media/us/mac/getamac/2009/apple-mvp-biohazard_suit-us-20090419_480x272.mov"]; if (movieURL != nil) { moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; moviePlayer.initialPlaybackTime = -1.0; // Register to receive a notification when the movie has finished playing. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerScalingModeDidChangeNotification object:moviePlayer]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(endPlay:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer]; moviePlayer.scalingMode = MPMovieScalingModeAspectFit; moviePlayer.movieControlMode = MPMovieControlModeDefault; moviePlayer.backgroundColor = [UIColor blackColor]; [moviePlayer play]; } }

    I have changed my code to this way. Now mail controller is opening in landscape mode. But the problem is If I touch on cancel button or send button the mail controller is not dismissing its view. How can I do it ? -(void)goToFirstScreen:(id)sender { NSLog(@"goToFirstScreen: "); CCScene *Scene = [CCScene node]; CCLayer *Layer = [EmailScene node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] pushScene: Scene]; } Th EmailScene class is #import "EmailScene.h" #import "testOfEnd.h" @implementation EmailScene - (id) init { self = [super init]; if (self != nil) { [self displayComposerSheet]; } return self; } -(void)displayComposerSheet { [[CCDirector sharedDirector] pause]; picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [[[CCDirector sharedDirector] openGLView] addSubview:picker.view]; [[CCDirector sharedDirector] stopAnimation]; [picker presentModalViewController:picker animated:YES]; [picker release]; } - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [[CCDirector sharedDirector] resume]; //dismiss view after otherwise the code is not executed [picker.view removeFromSuperview]; [[CCDirector sharedDirector] startAnimation]; [picker dismissModalViewControllerAnimated:YES]; //return to previous scene CCScene *Scene = [CCScene node]; CCLayer *Layer = [testOfEnd node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] replaceScene:Scene]; } @end Thank You.

  • Arrow keys with NSTableView

    - by dreamlax
    Is it possible to navigate an NSTableView's editable cell around the NSTableView using arrow keys and enter/tab? For example, I want to make it feel more like a spreadsheet. The users of this application are expected to edit quite a lot of cells (but not all of them), and I think it would be easier to do so if they didn't have to double-click on each cell.

  • Register NSService with Command Alt NSKeyEquivalent

    - by mahal tertin
    my Application provides a Global Service. I'd like to install the service with a command-alt-key combination. the thing i do now is not very error prone and really hard to debug as don't really see what's happening: inside Info.plist: <key>NSServices</key> <array> <dict> <key>NSSendTypes</key> <array> <string></string> </array> <key>NSReturnTypes</key> <array> <string></string> </array> <key>NSMenuItem</key> <dict> <key>default</key> <string>Go To Window in ${PRODUCT_NAME}</string> </dict> <key>NSMessage</key> <string>bringZFToForegroundZoomOut</string> <key>NSPortName</key> <string>com.raskinformac.${PRODUCT_NAME:identifier}</string> </dict> </array> and in the code: CFStringRef serviceStatusName = (CFStringRef)[NSString stringWithFormat:@"%@ - %@ - %@", appIdentifier, appName, methodNameForService]; CFStringRef serviceStatusRoot = CFSTR("NSServicesStatus"); CFPropertyListRef pbsAllServices = (CFPropertyListRef) CFMakeCollectable ( CFPreferencesCopyAppValue(serviceStatusRoot, CFSTR("pbs")) ); // the user did not configure any custom services BOOL otherServicesDefined = pbsAllServices != NULL; BOOL ourServiceDefined = NO; if ( otherServicesDefined ) { ourServiceDefined = NULL != CFDictionaryGetValue((CFDictionaryRef)pbsAllServices, serviceStatusName); } NSUpdateDynamicServices(); NSMutableDictionary *pbsAllServicesNew = nil; if (otherServicesDefined) { pbsAllServicesNew = [NSMutableDictionary dictionaryWithDictionary:(NSDictionary*)pbsAllServices]; } else { pbsAllServicesNew = [NSMutableDictionary dictionaryWithCapacity:1]; } NSDictionary *serviceStatus = [NSDictionary dictionaryWithObjectsAndKeys: (id)kCFBooleanTrue, @"enabled_context_menu", (id)kCFBooleanTrue, @"enabled_services_menu", @"@~r", @"key_equivalent", nil]; [pbsAllServicesNew setObject:serviceStatus forKey:(NSString*)serviceStatusName]; CFPreferencesSetAppValue ( serviceStatusRoot, (CFPropertyListRef) pbsAllServicesNew, CFSTR("pbs")); Boolean result = CFPreferencesAppSynchronize(CFSTR("pbs")); if (result) { NSUpdateDynamicServices(); JLog(@"successfully installed our alt-command-R service"); } else { ALog(@"couldn't install our alt-command-R service"); } and to change the service: // once installed, its's a bit tricky to set new ones (works only in RELEASE somehow?) // quit finder // open "~/Library/Preferences/pbs.plist" and remove ch.ana.Zoom - Reveal Window in Zoom - bringZFToForegroundZoomOut inside NSServicesStatus and save // start app // /System/Library/CoreServices/pbs -dump_pboard (to see if it hat actually done what we wanted, might be empty) // /System/Library/CoreServices/pbs (to add the new services) // /System/Library/CoreServices/pbs -dump_pboard (see new linking) // and then /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder -NSDebugServices MY.APP.IDENTIFIER to restart finder so my question: is there a easier way to enable a Service with cmd-option-key? if yes, i'd gladly implement it in my software.

  • iPhone dev: Recurse all project resoureces and collect paths

    - by thomax
    I have a bunch of HTML resources in my app organized in a hierarchy like so: dirA |---> index.html |---> a1.html |---> a2.html |---> dirB |---> b1.html |---> b2.html |---> dirC |---> c5.html |---> c19.html I'm trying to collect the absolute paths of all HTML resources however deep down, but can't seem to figure out how. So far I've tried: NSArray myPaths = [[NSBundle mainBundle] pathsForResourcesOfType:@"html" inDirectory:nil]; This returns an empty array, because I have no HTML files at the root of my project. Then there is: NSArray myPaths = [[NSBundle mainBundle] pathsForResourcesOfType:@"html" inDirectory:@"dirA"]; This returns an array containing only the paths for the three HTML resources directly below dirA. If I read the doc correctly, I guess this is to be expected; pathsForResourcesOfType does not traverse subdirectories. But is there a (preferably nice) way to do it?

  • Memory Leaks when touching UITableViewCells and poping off view.

    - by Falcon
    Hi All, I'm currently having a problem where the leaks tool is reporting a slew of memory leaks after clicking on cells within a UITableView and then hitting the back button and popping off the view. Majority of the leaks reported can not be traced back to any specific location in my code, they are: Leaked Object # Address Size Responsible Library Responsible Frame NSCFArray 2 < multiple > 64 UIKit -[UITouch(UITouchInternal) UITouch 2 < multiple > 128 GraphicsServices PurpleEventCallback Malloc 48 Bytes 2 < multiple > 96 Foundation -[NSCFArray insertObject:atIndex:] UIDelayedAction 2 < multiple > 96 UIKit -[UILongPressGestureRecognizer startTimer] NSCFArray 2 < multiple > 64 UIKit -[UILongPressGestureRecognizer touchesBegan:withEvent:] Malloc 32 Bytes 2 < multiple > 64 Foundation -[NSCFArray insertObject:atIndex:] Malloc 16 Bytes 2 < multiple > 32 Foundation -[NSCFSet unionSet:] Now I have commented out all my code in any touch event functions that I have written and it still leaks if I click on the cell a few times and then hit the back button to return to the previous view. Any ideas on what might actually be the problem here? Thanks,

  • Objective C - Constants with behaviour

    - by Akshay
    Hi, I'm new to Objective C. I am trying to define Constants which have behavior associated with them. So far I have done - @interface Direction : NSObject { NSString *displayName; } -(id)initWithDisplayName:(NSString *)aName; -(id)left; // returns West when North -(id)right; // return East when North @end @implementation Direction -(id)initWithDisplayName:(NSString *)aName { if(self = [super init]) { displayName = aName; } return self; } -(id)left {}; -(id)right {}; @end Direction* North = [Direction initWithDisplayName:@"North"]; // error - initializer element is not constant. This approach results in the indicated error. Is there a better way of doing this in Objective C.

  • Own data format for the iPhone

    - by Stefan
    Hi, I would like to create my own data format for an iPhone app. The files should be similar structured as e.g. Apple's iWork files (.pages). That means, I have a folder with some files in it: The file 'Juicy.fruit' contains: Fruits ---> Apple.xml ---> Banana.xml ---> Pear.xml ---> PreviewPicture.png This folder "Fruits" should be packed in a handy file 'Juicy.fruit'. Compression isn't necessary. How could I achieve this? I've discovered some open source ZIP-libraries. However, I would like to to build my own data format with the iPhones built-in libs (if possible). Best regards, Stefan

  • NSUndoManager, Core Data and selective undo/redo

    - by Combat
    I'm working on a core data application that has a rather large hierarchy of managed objects similar to a tree. When a base object is created, it creates a few child objects which in turn create their own child objects and so on. Each of these child objects may gather information using NSURLConnections. Now, I'd like to support undo/redo with the undoManager in the managedObjectContext. The problem is, if a user creates a base object, then tries to undo that action, the base object is not removed. Instead, one or more of the child objects may be removed. Obviously this type of action is unpredictable and unwanted. So I tried disabling undo registration by default. I did this by calling disableUndoRegistration: before anything is modified in the managedObjectContext. Then, enabling undo registration before base operations such as creating a base object the again re-disabling registrations afterwords. Now when i try to undo, I get this error: undo: NSUndoManager 0x1026428b0 is in invalid state, undo was called with too many nested undo groups Thoughts?

  • Interface Builder "Simulate Interface" not working

    - by bpapa
    I am using Interface Builder to play around with some ideas. I never noticed that there is a "Simulate Interface" feature which apparently will render the nib in the iPhone simulator. So, I created a view, put one component in there (a Segmented Control), saved it, selected "Simulate Interface", the simulator launched but... nothing rendered in the simulator. Just a black screen. I thought maybe my nib wasn't complete enough, so I've tried it with all of my old nibs and I'm having the same problem with all of them. None of them render in the simulator at all. Is there some trick that I'm missing?

  • Limit to area that receives touch events

    - by Typeoneerror
    Is there's a bounding box on an application that receives touch events? I created a few sample round rect buttons and placed them in different places in my view. The ones in the center of the view receive touch events (and show the highlighted blue color) but if I place a button near the edges of the view, only parts of them are clickable in the simulator. Is this because of Apples style guidelines? I placed a button exactly where a UITabNavigationItem would appear and only the bottom half of it is clickable.

  • How can I write a scrolling text in cocos2d ?

    - by srikanth rongali
    I have a text and it should be abled to scrolled only up and down to see entire text. and my application is a game and written in cocos2d. So, I have layers. There is also an image(CCSprite) adjacent to text. The text should be scrolled and the image have a touchesEnded: property. I used CCLabel for text and CCParallaxNode to add the text. But the text appears like a continues paragraph. But, my text should have different lines. My text is like this. //text starts Hey Player. Do you want to play the game right now then play. Do you want to practice or Play? what want to do? ...text continues //text ends What should I use for this ? Thank you.

  • iPhone Multithreaded Search

    - by Kulpreet
    I'm sort of new to any sort of multithreading and simply can't seem to get a simple search method working on a background thread properly. Everything seems to be in order with an NSAutoreleasePool and the UI being updated on the main thread. The app doesn't crash and does perform a search in the background but the search results yield the several of the same items several times depending on how fast I type it in. The search works properly without the multithreading (which is commented out), but is very slow because of the large amounts of data I am working with. Here's the code: - (void)filterContentForSearchText:(NSString*)searchText { isSearching = YES; NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init]; /* Update the filtered array based on the search text and scope. */ //[self.filteredListContent removeAllObjects]; // First clear the filtered array. for (Entry *entry in appDelegate.entries) { NSComparisonResult result = [entry.gurmukhiEntry compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])]; if (result == NSOrderedSame) { [self.filteredListContent addObject:entry]; } } [self.searchDisplayController.searchResultsTableView performSelectorOnMainThread:(@selector(reloadData)) withObject:nil waitUntilDone:NO]; //[self.searchDisplayController.searchResultsTableView reloadData]; [apool drain]; isSearching = NO; } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { if (!isSearching) { [self.filteredListContent removeAllObjects]; // First clear the filtered array. [self performSelectorInBackground:(@selector(filterContentForSearchText:)) withObject:searchString]; } //[self filterContentForSearchText:searchString]; return NO; // Return YES to cause the search result table view to be reloaded. }

  • How to store (and use) the current mouse position?

    - by Ben Packard
    What is the best way to store the current mouse position (system-wide) and then (later) put the mouse at that stored point? [NSEvent mouseLocation] gets me the position, and I can move the mouse with a CGEventMouseMoved, but they each use a different co-ordinates system (I believe y=0 is the top for NSEvent and the bottom for a CGEvent). I'm worried about the robustness of capturing the screen height and using it to convert between the two - or is this the best approach?

  • Interface Builder caching bad data (voodoo)

    - by Ryan Townshend
    Sometimes IB will hold onto old or bad references, and I cannot seem to remove or edit them. EDIT I have made this a wiki question with the intention of gathering more data on the phenomenon. Answers involving situations where other coders have encountered this are welcome. This happened to me again last night with a table controller. When I created a spike project to try and reproduce the error, the system worked the way I anticipated. Then back in the actual project the bad behavior continued, even if I remove the xib file and all controllers involved. Creating a whole new project with none of the original (problematic) xib and nib files worked correctly. This question is not about the specifics of this incident but about this type of incident in IB. Does anyone know more about this type of bad IB behaviour, and possibly a more stylish way to to eliminate it than nuking the project? Note, removing the offending IB files and recreating them in the same project has not solved this for me in the past, only whole new projects. Answers regarding examples of when/how this glitch has been observed/created are welcome as well.

  • A way to enable a LaunchDaemon to output sound?

    - by Varun Mehta
    I have a small Foundation application that checks a website and plays a sound if it sees a certain value. This application successfully plays a sound when I run it as my user from the Terminal. I've configured this app to run as a LaunchDaemon, with the following plist: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>org.myorg.appidentifier</string> <key>ProgramArguments</key> <array> <string>/Users/varunm/path/to/cli/application</string> </array> <key>KeepAlive</key> <true/> <key>RunAtLoad</key> <true/> </dict> </plist> When I have this service launched I can see it successfully read in and log values from the website, but it never generates any sound. The sound files are located in the same directory as the binary, and I use the following code: NSSound *soundToPlay = [[NSSound alloc] initWithContentsOfFile:@"sound.wav" byReference:NO]; [soundToPlay setDelegate:stopper]; [soundToPlay play]; while (g_keepRunning) { [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1.0]]; } [soundToPlay setCurrentTime:0.0]; Is there any way to get my LaunchDaemon application to play sound? This machine gets run by different people, and sometimes has no one logged in, which is why I have to configure it as a LaunchDaemon.

  • My framework will utilise other frameworks, but I'd like this to be transparent to the end-user

    - by d11wtq
    I'm building a framework, which aims to provide a new development environment for the user, but I need to use things like RegexKit and almost certainly some other established frameworks in order to do this. Any functionality exposed from such frameworks would be abstracted through classes and methods in my own framework for maintenance reasons (allowing me to change my mind on which dependencies I want). In an ideal world I just want to ship a single .framework. However I'm aware that unlike with standard bundles and applications it is not possibile to embed a framework inside the framework bundle. Do I have any other option other than to tell the end user that they must also install RegexKit and any other dependencies? I have a feeling this lessens the appeal value of the easy to use embedded framework I'd envisaged building. Right now I'm feeling like I have some limited options: Force the user to install the dependencies. Write my own classes that provide the same functionality -- ugh! If at all possible, try to statically link the third party frameworks (is this possible??) My end-product is ideally a single .framework bundle that uses @rpath and so can be installed in the system or simply bundled with the app that uses it.

  • Can I detect if higher subview has been touched?

    - by Kevin Beimers
    I've got a big UIView that responds to touches, and it's covered with lots of little UIViews that respond differently to touches. Is it possible to touch anywhere on screen and slide around, and have each view know if it's being touched? For example, I put my finger down on the upper left and slide toward the lower right. The touchesBegan/Moved is collected by the baseView. As I pass over itemView1, itemView2, and itemView3, control passes to them. If I lift my finger while over itemView2, it performs itemView2's touchesEnded method. If I lift my finger over none of the items, it performs baseView's touchesEnded. At the moment, if I touch down on baseView, touchEnded is always baseView and the higher itemViews are ignored. Any ideas?
