  • Recording custom overlay on iPhone

    - by Marc
    Hi all, I'm interested in recording a video with a custom overlay which would end up in the video itself. They could be UIImage or even better, an OpenGL viewport, is there even such possibility right now on any iPhone devices/SDK ? Thanks

  • Why am I getting a EXC_BAD_ACCESS in a NSTimer selector?

    - by AngeDeLaMort
    I've got quite a weird problem. To make it short, i'll write some pseudo-code: init: create a dictionary and insert n elements. create a "repeat timer" and add it to the currentRunLoop using the timerRefresh selector. timerRefresh: using a list of keys, find the items in the dictionary if the item exists -> call a function So, for an unknown reason, I get an EXC_BAD_ACCESS when I do: [item function]; But I traced the address I got from the dictionary items and it's ok. The ref count of the items in the dictionary is still 1. The {release, dealloc} of the items in the dictionary aren't called. Everything seems fine. Also, to make it worst, it works for some items. So, I'm wondering if there is a threading problem? or something else obscure? The callstack is quite simple: #0 0x93e0604b in objc_msgSend_fpret #1 0x00f3e6b0 in ?? #2 0x0001cfca in -[myObject functionm:] at myObject.m:000 #3 0x305355cd in __NSFireTimer #4 0x302454a0 in CFRunLoopRunSpecific #5 0x30244628 in CFRunLoopRunInMode #6 0x32044c31 in GSEventRunModal #7 0x32044cf6 in GSEventRun #8 0x309021ee in UIApplicationMain #9 0x000027e0 in main at main.m:14 So, any suggestion where to look would be appreciated.

  • Accessing Amazon E-Commerce Services through Cocoa Touch

    - by Gregory Hill
    Has anyone successfully accessed AWS (Amazon E-Commerce Services) through Cocoa Touch? I've been digging around, and haven't seen the issue addressed directly. I've created an AWS account, and have seen some sample code for accessing web services through Cocoa, but I'm not quite sure how to tie it all together. If anyone has any sample code, I'd love to see it. I'm just trying to get my head around the concepts.

  • iPhone dev: UIBarButtonItem or title not showing up in NavigationBar

    - by IceMan85
    Hello everyone, here my problem. I have a NavigationBar at the top, a TabBar at the bottom and a TableView at the center of the screen. Very normal situation. I set it all up in IB and I have set this in the app delegate : ExpensesListNavController *expensesListNavController; This in order to be able to add new views to the stack. I need to have 3 levels: - list of items in a TableView - OK - firstLevel: once pressed one cell a view is added to the stack - OK - second level: one pressed the "modify" button on the navBar on the firstLevel I want to show a new view that can be customized by the user. My Problem is coming when trying to add the "Modify" button in the "firstLevelView". Here-below my code -(IBAction) modify:(id)sender { if (editableDetailViewController == nil) { editableDetailViewController = [[editableDetailViewController alloc] init]; } editableDetailViewController.expense = expense; [appDelegate.expensesListNavController pushViewController:editableDetailViewController animated:YES]; editableDetailViewController = nil; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; appDelegate = [[UIApplication sharedApplication] delegate]; UIBarButtonItem *modifyButton = [[UIBarButtonItem alloc] initWithTitle:@"Modify" style:UIBarButtonItemStylePlain target:self action:@selector(modify:)]; appDelegate.expensesListNavController.navigationItem.rightBarButtonItem = modifyButton; appDelegate.expensesListNavController.navigationItem.title = @"Titoloooo"; NSLog(@"NavBar button has just been set !!"); [modifyButton release]; Nothing is being showed, neither title nor the button. Do you have any idea of what is happening ?? I really cannot figure out !!! Thanks a lot in advance, AM

  • Code Interaction with Quartz Composition

    - by Alberto MQO
    Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

  • get data from online once and then viewable offline

    - by user313100
    Okay, I want to have an app that takes phone numbers from an online database and displays them in a table view. When the user is not online, I want them to still be able to see the numbers they already got from the database in the table view. If the user manages to go back online, the database updates the view. My question is, is this possible to do and if so, what's the best way to approach it? (bit of a newbie, please help me out)

  • Doxygen including methods twice doc files

    - by Maarek
    I'm having this issue where doxygen is adding the method twice in the documentation file. Is there a setting that stops auto-generation of documentation for methods within the .m file. For example in the documentation I'll see something like whats below where the first definition of + (Status *)registerUser is from the header XXXXXX.h file where the second is from XXXXXX.m. Header documentation : /** @brief Test Yada Yada @return <#(description)#> */ + (Status *)registerUser; Output: + (Status *) registerUser Test Yada Yada. Returns: <#(description)#> + (Status *) registerUser <#(brief description)#> <#(comprehensive description)#> registerUser Returns: <#(description)#> Definition at line 24 of file XXXXXX.m. Here are the build related configuration options. I've tried playing with them. EXTRACT_ALL with YES and NO... Hiding uncodumented Members and Classes. #--------------------------------------------------------------------------- # Build related configuration options #--------------------------------------------------------------------------- EXTRACT_ALL = NO EXTRACT_PRIVATE = NO EXTRACT_STATIC = NO EXTRACT_LOCAL_CLASSES = YES EXTRACT_LOCAL_METHODS = NO EXTRACT_ANON_NSPACES = NO HIDE_UNDOC_MEMBERS = YES HIDE_UNDOC_CLASSES = YES HIDE_FRIEND_COMPOUNDS = NO HIDE_IN_BODY_DOCS = NO INTERNAL_DOCS = NO CASE_SENSE_NAMES = NO HIDE_SCOPE_NAMES = NO SHOW_INCLUDE_FILES = YES FORCE_LOCAL_INCLUDES = NO INLINE_INFO = YES SORT_MEMBER_DOCS = YES SORT_BRIEF_DOCS = NO SORT_MEMBERS_CTORS_1ST = NO SORT_GROUP_NAMES = NO SORT_BY_SCOPE_NAME = NO

  • iPhone NSMutableDictionary setObject forKey after initWithContentsOfFile

    - by andrew
    so here's my function + (void) AddAddress:(NSString*)ip:(NSString*)mac { NSMutableDictionary* currentAddresses = [[NSMutableDictionary alloc] initWithContentsOfFile:[self filePath:ADDRESSES_FILE]]; [currentAddresses setObject:mac forKey:ip]; [Configuration Write:currentAddresses]; [currentAddresses release]; } [self filePath:ADDRESSES_FILE] returns a string containing the full path of a file (ADDRESSES_FILE) located in the Documents. The file may not exist, in this case I want to just write an object to the dictionary and then write it down the problem is that when i do setObject forKey it doesn't add anything to the dict (if i just do alloc init to the dict, it works fine, but i want to read the records from the file, if there are any, and replace/add a record by using the AddAddress function)

  • COCOA: Programatically creating new windows and accessing window objects

    - by Jeffrey Kern
    I'm having an issue with creating new windows in Cocoa. Hypothetically speaking, lets say I have "WindowA" and has a button called "myButton". When you click on "myButton", it runs this code in the following class file: -(void)openFile2:(id)sender { myNextWindow = [[TestWindowController alloc] initWithWindowNibName:@"MainMenu"]; NSString *testString = @"foo"; [myNextWindow showWindow:self]; [myNextWindow setButtonText:testString]; } The code in a nutshell makes a duplicate "WindowA" and shows it. As you can see, this code also runs a method called 'setButtonText', which is this: - (void)setButtonText:(NSString *)passedText { [myButton setTitle:passedText]; } The problem is that when I call this method locally, in the original window - the button text changes (e.g., [self setButtonText:testString]) it works. However, it does not work in the newly created window (e.g., [myNextWindow setButtonText:testString];) When I debug the newly created window, step by step, the 'myButton' value it gives is 0x0. Do I have to manually assign controllers/delegates to the new window? I think the 'myButton' in the code isn't associated to the 'myButton' in the newly created window. How would I fix this problem?

Is it possible to modify the class in order to be able to initialize it like a normal object? [[myManagedObject alloc] init]; Thanks edit: to clarify the question, will it screw everything up if I change the @dynamic with @synthesize in the implementation?

I tried it the following way if([self image]==[UIImage imageNamed:@"image1.png"]); but this does not work. Is there a straight forward way for this?

  • Specific Strings And NSScanner

    - by Garry
    I need to determine whether a string (sourceString) contains another string (queryString) and if it does, at what offset. I'm guessing that NSScanner might do the trick but I don't fully understand the documentation. Let's say sourceString = @"What's the weather in London today?" If I set queryString to equal @"What's the weather", I'd like a method that would determine that, in this case, YES (sourceString does contain queryString) and the offset is 0 (i.e. at the start of sourceString). Any suggestions?
