  • iPhone adding a timer to an app

    - by Rob J
    How would I go about adding a simple 2 minute timer to my app in almost the exact same way that the clock app does? I just want the user to click start and have the timer start displaying the timer counting down from 2:00 and beep when it hits 0:00.

  • Reading Microsoft word document in iphone

    - by Arnieterm
    Hi All Using CGPDFDocument class we can read pdf document, get number of pages, get a page by number. Is there any other library that helps us reading word documents like microsoft word doc where we can get number of pages and get a page by its number etc? Do not want to use safari to view the document. I have seen some apps on app store that claims to read MS Office docs like docx, xlsx etc. Does there exists any library [even static] that we can make use of? Any idea? Thanks Arnieterm

  • iPhone NSDateFormatter Timezone Conversion

    - by MobileDeveloperTips
    I am trying to create a formatter that will convert the date format shown to an NSDate object: NSString *dateStr = @"2010-06-21T19:00:00-05:00"; NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZZZ"]; NSDate *date = [dateFormat dateFromString:dateStr]; The issue is the timezone -05:00, which is not parsed properly with the format above. Any suggestions?

  • One iPhone, two developer machines

    - by willcodejavaforfood
    Hi all, I switch between my iMac and MacBook when working on my apps. I've always used my iMac to test the apps on the actual device, but I would like to be able to do this from both computers. I cannot seem to use the profile on my MacBook as it does not have the correct Certificate Signing Request in the KeyChain. Is there a way to copy these between machines and KeyChains? :)

  • iPhone -trouble with a loading data from webservice into a tableview

    - by medampudi
    I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

  • Releasing an NSTimer iPhone?

    - by Conor Taylor
    I have an NSTimer declared in my .h and in the viewDidLoad of the /m I have the code: timer = [NSTimer scheduledTimerWithTimeInterval:kComplexTimer target:self selector:@selector (main) userInfo:nil repeats:YES]; I also have [timer release]; in my dealloc. However when I exit the view and return to it, the timer has not in fact released, it has doubles in speed! How do I solve this & what am I doing wrong??? Thanks

  • Loading more than 10 images on iPhone??

    - by SeniorLee
    I'm trying to add more than 10 pictures on ScrollView. NSUInteger i; for (i = 1; i <= numberOfImage; i++) { NSString *imageName = [NSString stringWithFormat:@"d%dimage%d.png", imageSection, i]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList" CGRect rect = imageView.frame; rect.size.height = kScrollObjHeight; rect.size.width = kScrollObjWidth; imageView.frame = rect; imageView.tag = i; // tag our images for later use when we place them in serial fashion [scrollView addSubview:imageView]; [imageView release]; } This code is from Apple example and it works fine. But if the variable 'i' is bigger than 10, 'UIImage *image' is empty. The imageName seems to correct. But I don't know why it does not load image. Does anybody sees the problem?? And one more thing. If I do like that, does iOS controls memory automatically? I mean it's kind of wasting memory if all (more than 10) images are loaded on memory even they are not displayed. I've heard that iOS loads images only displayed on screen and free images those are not displayed. Is that right? Thanks for reading.

  • iphone selecting a row to change view

    - by Rob J
    I have created the view Controllers and attached those to control their respective views. I can't figure out how to make the following code to go the right views though. (This is in the root view controller:) - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { RunViewController *runViewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]]; CalcViewController *calcViewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]]; PushViewController *pushViewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]]; SitViewController *sitViewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]]; TimerViewController *timerViewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:runViewController animated:YES]; [runViewController release]; [self.navigationController pushViewController:pushViewController animated:YES]; [pushViewController release]; [self.navigationController pushViewController:sitViewController animated:YES]; [sitViewController release]; [self.navigationController pushViewController:timerViewController animated:YES]; [timerViewController release]; [self.navigationController pushViewController:calcViewController animated:YES]; [calcViewController release]; runViewController = nil; pushViewController = nil; sitViewController = nil; timerViewController = nil; calcViewController = nil; } Each time I select any of the rows in the table - all of the views come up. How do I arrange them to only open the view that it is supposed to?

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

  • Determining where in the code an error came from - iPhone

    - by Robert Eisinger
    I'm used to Java programming where an error is thrown and it tells you at what line the error was thrown from which file. But with Objective-C in XCode, I can't ever tell where the error comes from. How can I figure out where the error came from? Here is an example of a crash error: 2011-01-04 10:36:31.645 TestGA[69958:207] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableArray objectAtIndex:]: index 0 beyond bounds for empty array' *** Call stack at first throw: ( 0 CoreFoundation 0x01121be9 __exceptionPreprocess + 185 1 libobjc.A.dylib 0x012765c2 objc_exception_throw + 47 2 CoreFoundation 0x011176e5 -[__NSArrayM objectAtIndex:] + 261 3 TestGA 0x000548d8 -[S7GraphView drawRect:] + 5763 4 UIKit 0x003e16eb -[UIView(CALayerDelegate) drawLayer:inContext:] + 426 5 QuartzCore 0x00ec89e9 -[CALayer drawInContext:] + 143 6 QuartzCore 0x00ec85ef _ZL16backing_callbackP9CGContextPv + 85 7 QuartzCore 0x00ec7dea CABackingStoreUpdate + 2246 8 QuartzCore 0x00ec7134 -[CALayer _display] + 1085 9 QuartzCore 0x00ec6be4 CALayerDisplayIfNeeded + 231 10 QuartzCore 0x00eb938b _ZN2CA7Context18commit_transactionEPNS_11TransactionE + 325 11 QuartzCore 0x00eb90d0 _ZN2CA11Transaction6commitEv + 292 12 QuartzCore 0x00ee97d5 _ZN2CA11Transaction17observer_callbackEP19__CFRunLoopObservermPv + 99 13 CoreFoundation 0x01102fbb __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ + 27 14 CoreFoundation 0x010980e7 __CFRunLoopDoObservers + 295 15 CoreFoundation 0x01060bd7 __CFRunLoopRun + 1575 16 CoreFoundation 0x01060240 CFRunLoopRunSpecific + 208 17 CoreFoundation 0x01060161 CFRunLoopRunInMode + 97 18 GraphicsServices 0x01932268 GSEventRunModal + 217 19 GraphicsServices 0x0193232d GSEventRun + 115 20 UIKit 0x003b842e UIApplicationMain + 1160 21 TestGA 0x00001cd8 main + 102 22 TestGA 0x00001c69 start + 53 23 ??? 0x00000001 0x0 + 1 So from looking at this, where is the error coming from and from which class is it coming from?

  • iphone detailtext in UITableView question

    - by Rob
    So, I am able to create an array that populates the fields of the Table, but am having troubles creating the subtext that appears below the main fields. I currently have: - (void)viewDidLoad { [super viewDidLoad]; listOfForms = [[NSMutableArray alloc] init]; [listOfForms addObject:@"First Form"]; } and then: NSString *cellValue = [listOfDAForms objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; in the cellForRowAtIndexPath portion. Why can't I add: listOfNames = [[NSMutableArray alloc] init]; [listOfNames addObject:@"Named Form"]; and NSString *cellSubscript = [listOfNames objectAtIndex:indexPath.row]; cell.detailTextLabel.text = cellSubscript; in order to make the little subview work? What am I doing wrong?

  • Pre loaded database on iPhone?

    - by Julian
    Hi, I have recently developed an app using core data as the storage db. The app allowed the user to read and write to the db. I am now developing a new app which the user doesnt need to write anything to the db, instead the app just needs to read the data. The data has relationships etc so cannot just use a plist or something similar. My question is should I use core data for such a requirement and if so how would i go about entering the data and then releasing the app. Would I have to code the data entry which would populate the db then remove all this code (as I dont want the database to repopulate every time the user opens the app)?? Is there a way to create a core data model using sql commands as with sqlite ie insert into..... etc? Any ideas/thoughts would be very helpful. Many thanks Jules

Thanks

  • iPhone Development - CoreData runtime error

    - by Mustafa
    I'm facing a strange CoreData issue. Here's the log: 2010-04-07 15:59:36.913 MyProject[263:207] <MyEntity: 0x180370> (entity: MyEntity; id: 0x17e890 <x-coredata://0F55C533-41BD-4F09-9CCA-0CB304CAB065/MyEntity/p380> ; data: <fault>) 2010-04-07 15:59:36.918 MyProject[263:207] *** Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'The NSManagedObject with ID:0x17e890 <x-coredata://0F55C533-41BD-4F09-9CCA-0CB304CAB065/MyEntity/p380> has been invalidated.' I have a hierarchy of UITableViewControllers that use NSFetchedResultsController to populate the table, and when a particular row is selected, the detail view is shown. UITableView (MyMainEntity) UITableView (MyEntity) UITableView (MyEntity) detail view Both MyMainEntity UITableView and MyEntity UITableView use NSFetchedResultsController to show the records. Sometimes it crashes when i'm scrolling the tableView, and sometimes it crashes when i try to open the detail view. I can navigate to the MyEntity detail view multiple times before application crashes. What does this error mean? and how can i fix it!?

  • Iphone does not recognize reneweed ad hoc provising profile

    - by Amnon Dekel
    I installed a new version of an app we are developing, and also a new ad hoc provisioning profile (the old one had expired). I removed the app and profile from the phone and from itunes. Added the new profile and app to itunes and synched. All seemed well- the new profile was on the phone and the new app too. But when trying to launch the app, I get an alert: "the application cannot be opened because the provisioning profile has expired". I removed and reinstalled. I rebooted the phone. Nothing helped. Any ideas? Thanks
