  • 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?

  • 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

  • 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

  • Iphone -- maintaining a list of strings and a corresponding typedef enum

    - by William Jockusch
    Suppose I have the following: typedef enum functionType {ln, sin, sqrt} functionType; NSArray *functions = [NSArray arrayWithObjects: @"ln", @"sin", @"sqrt", nil]; Suppose further that *functions will not change at runtime. Question -- is there any way to set up a single structure which updates both of these? So that I only have to keep track of one list, instead of two. To explain what is going on -- the idea is that string input from the user will be stored in a variable of type functionType. Later on, I will have code like this: double valueOfFunction: (functionType) function withInput: (double) input switch (function) { case ln: return ln(input); case sin: return sin(input); case sqrt: return sqrt(input); //etc . . . could grow to include a lot of functions. } And valueOfFunction needs to be fast. So I don't want to be doing string comparisons there.

  • iPhone memory management: a release after setting self.someProperty = nil

    - by ddawber
    I am reading the LazyTableImages code that Apple have released and they do something to this effect (in an NSOperation subclass): - (void)dealloc { [myProperty release]; [myProperty2 release]; } - (void)main { // // Parse operation undertaken here // self.myProperty = nil; self.myProperty2 = nil; } My thinking is that they do this in case dealloc is called before setting properties to nil. Is my thinking correct here? Are the releases unnecessary, as self.myProperty = nil effectively releases myProperty? One thing I have noticed in this code is that they don't release all retained objects in dealloc, only some of them, which is really the cause for my confusion. Cheers

  • iPhone - NSURLConnection does not receive data

    - by Jukurrpa
    Hi, I have a pretty weird problem with NSURLRequest. I'm using them to make an asynchronous image loading in an UITableView. The first time the tableView displays, all connections from NSURLRequests open correctly but receive absolutely no data, regardless of how long I wait. But as soon as I scroll down in the tableView, the newly created requests for the new cells work perfectly! The only way for the images on top of the tableView to load is to make them disappear by scrolling down and then up again, in order to create new requests. Here is what I do in "cellForRowAtIndexPath": UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWIthFrame:CGRectMake(0, 0, 300, 60)]; AsyncUIImageView imageView = [[AsynUIImageView alloc] initWithFrame:CGRectMake(0, 0, 60, 60)]; imageView.tag = IMG_VIEW // an enum for tags [cell addSubView:imageView]; [imageView release]; } AsyncUIImageView imageView = (AsyncUIImageView*)[cell viewWithTag:IMG_VIEW]; // I do a few cache checks here, but if the image aint cached I do this: [imageView loadImageFromURL:@"http://someurl.com/somepix.jpg"]; // all urls are different, just an example The AsyncUIImageView inherits from UIImageView and contains an NSURLConnection which opens upon calling the loadImageFromURL method: (void) loadImageFromURL:(NSString*)filename { if (self.connection != nil) [self.connection release]; if (self.data != nil) [self.data release]; NSURLRequest* request = [NSURLRequest requestWithURL:[[NSURL alloc] initWithString:fileName] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0]; self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; if (self.connection == nil) return; self.data = [[NSMutableData data] retain]; } I've created the delegate methods "connection: didReceiveData", which appends received data to self.data and "connectionDidFinishLoading" which sets the image and closes the connection once the transfer is complete. These work, but are never called for the first requests I create. I suspect this bug to come from the main thread not giving the first requests the control so they can execute themselves, as the same behavior happens if I keep my finger on the screen after a scroll: connections open themselves, but no data is received until I stop touching the screen. What am I doing wrong?

  • 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?

  • iPhone: Switching Views From Outside Root Controller

    - by senfo
    I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

  • 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.

  • Reading html with accented characters from a URL on iPhone

    - by lbh
    Hello, I'm having trouble extracting the html from a website which contains accented characters. Specifically, there are French characters on the site. Currently I'm using: NSString* html= [NSString stringWithContentsOfURL: [NSURL URLWithString: url] usedEncoding: &enc error:&error]; to get html from a URL. It works perfectly fine for any sites which are all English, but with a mostly English site with French characters it returns nothing. I've tried a few different types of encoding, but none have worked for me. Any suggestions? Thanks.

  • popViewControllerAnimated doesn't update info iPhone SDK

    - by WrightsCS
    When I try to pop a view controller, it doesnt update info for the previous view. Example: I have a cell that displays text in a label in View1. When you click on the cell it goes to View2 (for example) When I choose an option in View2, popViewControllerAnimated is used to go back to View1, however, I want the label to now be updated with the new option in View1. My dilemma is that when I pop View2, the label in View1 does not update. Any ideas? I've tried adding a [view1 reloadData]; before the view pops, but no luck. //VIEW1 the cell that displays the label. ringLabel = [[UILabel alloc] initWithFrame: CGRectMake(25, 12.7f, 250, 20)]; ringLabel.adjustsFontSizeToFitWidth = YES; ringLabel.textColor = [UIColor blackColor]; ringLabel.font = [UIFont systemFontOfSize:17.0]; ringLabel.backgroundColor = [UIColor clearColor]; ringLabel.textAlignment = UITextAlignmentLeft; ringLabel.tag = 0; ringLabel.text = [plistDict objectForKey:@"MYOPTION"]; [ringLabel setEnabled:YES]; [cell addSubview: ringLabel]; [ringLabel release]; //VIEW2 when cell clicked CustomProfileViewController *cpvc = [CustomProfileViewController alloc]; cpvc.ringtone = [ringList objectAtIndex:indexPath.row]; [cpvc.tblCustomTable reloadData]; [self.navigationController popViewControllerAnimated:YES];

  • 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

  • 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 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?

  • 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...

  • 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
