  • 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.

  • How to stop the targets generated by schedule:@selector(target:) interval:timeInterval ?

    - by srikanth rongali
    I am using [self schedule:@selector(target:) interval:timeInterval]; for generating bullets in shooting game in cocos2d. In target: I called method targetGenerate to generate for bullet. The enemy generates these bullets. After the player won or enemy won the game the bullets should stop. But, I could not make them stop. I used flags for this. But they did either work. If I set flag1 = 1; for game won. I am using [self schedule:@selector(update:)]; for updating the bullet position to know it hits the player or not ? And I tried like this -(id)init { if( (self = [super init]) ) { //code for enemy [self schedule:@selector(target:) interval:timeInterval]; [self schedule:@selector(update:)]; }return self; } -(void)target:(ccTime)dt { if(flag != 1) [self targetGenerate]; } -(void)targetGenerate { //code for the bullet to generate; CCSprite *bullet = … } -(void)update:(ccTime)dt { //code for to know intersection of bullet and player } But it was not working. How can I make the bullets to disappear after player won the game or enemy won the game ? Thank you.

  • How do I enable spell checking within an NSTextField on Mac OS X?

    - by Luke
    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. 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.

  • Application crashing on getting updated information from database using timer and storing it on loca

    - by Amit Battan
    In our multi - user application we are continuously interacting with database. We have a common class through which we are sending POST queries to database and obtaining xml files in return. We are using delegates of NSXMLParser to parse the obtained file. The problem with us is we are facing many crashes in it generally when application is idle and changed data in database is being fetched in background through timer which is invoked after every few seconds. We have also dealt with error handling through try and catch but it proves to be of no use in this case and mostly application crashes with following error : Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000020 Strange thing is that many times the fetching of updated data at background works very fine, same methods being successfully executed under similar conditions but suddenly it crashes on one of them. The codes we are using is as follows: // we are using timer in this way: chkOnlineUser=[NSTimer scheduledTimerWithTimeInterval:15 target:mmObject selector:@selector(threadOnlineUser) userInfo:NULL repeats:YES];

  • Simple NSTableView bindings example

    - by sirjorj
    I am trying to populate a 2-column NSVTableView via bindings, but the data is not showing up in the table. In XCode: I have a NSMutableArray in my AppDelegate that will hold the data, as well as the corresponding @property and @synthesize. On an event, I call [removeAllObjects] on the NSMutableArray and repopulate it with some NSDictionary objects. Each dictionary contains 2 KVP's: a NAME and a VALUE. In IB: I added an NSArrayController and bound it's Content Array to my AppDelegate and set the ModelKeyPath to the name of the NSMutableArray in the AppDelegate. On the NSTableView, I bound the Content to the ArrayController. ControllerKey = "arrangedObjects", ModelKeyPath = empty. For each of the two columns, I bound the Value to the AppController and set the ModelKeyPaths to NAME and VALUE respectively. ControllerKey = "ArrangedObjects". I have tried several other things, such as using an NSArray in the app delegate and making a new one every time I need to update the values. There must be some tiny little thing I am forgetting. What is it? jorj

  • How can I launch QuickTime from my app?

    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.

  • 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?

  • How to select one NSCell in an NSTableView?

    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?

  • 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,

  • 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.

  • 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

  • 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.

  • 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.

  • Resources check

    - by Chris
    hey I am frequently uploading my XCode iPhone projects to an svn repository to be build on another machine. My problem is that when I add resources to my project sometimes I forget to add the resource as relative to the project. I know one answer is to be more careful (not easy when your tired!) but if there was a way to run a script to check my resource paths are relative when I build and warn me if they are not it would be a great time saver for me. How would I go about doing this? Thanks Chris

  • Do I need to override the writing methods of NSDocument in subclasses for an application that will o

    - by Abizern
    I think I may be missing the obvious but I'm not sure. The section on subclassing NSDocument in the docs states that subclasses of NSDocument must override one reading and one writing method. If I'm creating a viewer application that will not write anything back, do I still need to override a writing method (returning what, nil?) or can I ignore it and make sure that there are no saving methods that can get called?
