  • Daemon running as user nobody needs to copy file from Desktop

    - by Randall
    I have a daemon that is running as user nobody. It needs to copy a file that I specify into /Users/Shared/MyFolder If I tell it to copy a file that is already in /Users/Shared/ it works fine. If I tell it to copy it from somewhere in my home directory like the desktop, the copy fails. I'm using NSFileManager copyPath:toPath: Any ideas?

  • iPhone, confusing memory leak.

    - by fuzzygoat
    Can anyone tell me what I am doing wrong with the bottom section of code. I was sure it was fine but "Leaks" says it is leaking which quickly changing it o the top version stops, just not sure as to why the bottom variation fails? // Leaks says this is OK if([elementName isEqualToString:@"rotData-requested"]) { int myInt = [[self elementValue] intValue]; NSNumber *valueAsNumber = [NSNumber numberWithInt:myInt]; [self setRotData:valueAsNumber]; return; } . // Leaks says this LEAKS if([elementName isEqualToString:@"rotData-requested"]) { NSNumber *valueAsNumber = [NSNumber numberWithInt:[[self elementValue] intValue]]; [self setRotData:valueAsNumber]; return; } any help would be appreciated. gary

  • Objects in interface

    - by Peter Kowalchuk
    I created my own object, PKSurvey. In the interface of the View Controller I can define a pointer to it, then in a method I can alloc it and have an instance. How do I keep the instance beyond the method where it was allocated? I assign values in one method and want to be able to use those values in other methods. Should I allocate it in the viewDidLoad method or should I do it somewhere else? @interface DIrectionalDrillerViewController : UIViewController { PKSurvey *Survey=[PKSurvey new]; ---------------- - (void)viewDidLoad { [Survey new];

  • Dragging Files on the Dock Icon

    - by enchilada
    I know how handle dragging of files on the dock icon, and it has been asked before. However, I'm wondering, can I somehow get more control? For example, can I make the dock icon reject files that are not in the user's folder and allow only files that are in the user's folder? I'd rather do that instead of the app appearing as if it handles files outside the user's folder, and then within the app delegate afterwards reject the files by detecting the file paths. That doesn't seem good from a user's perspective.

  • Object sent -autorelease too many times

    - by mongeta
    I have this code that simple returns Today's date as a string formatted: +(NSString*) getTodayString_YYYY_MM_DD { NSDate * today = [NSDate date]; NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"yyyy-MM-dd"]; return [[formatter stringFromDate:today] autorelease]; } With instruments I'm not getting a memory leak, but when I Analyze, XCode says: Object sent -autorelease too many times If I understand correctly, I have to release manually the formatter as I'm creating it using 'alloc', but I can't release here because I have to return the value, so I add the autorelease. How I can do it better to improve it ? thanks, r.

  • Does NSKeyedUnarchiver autorelease?

    - by Lee Probert
    I'm doing some archiving to a property list and when I unarchive my data using NSKeyedUnarchiver I find that my app crashes if I release the object afterward. I was wondering if the finishDecoding message also autoreleases the object. Seems weird that it crashes when I release it.

  • Why does my UIScrollView change it's original content offset when I scroll?

    - by Tony
    Before I scroll, my UIScrollView is laid out perfectly. See here However if I scroll up, the view bounces as I go out of bounds and then resets too high. See here I am going to guess this has to do with a hack that I did earlier to get the view to originally show like in the first screen shot. For some reason, to get my view to look like the second screen shot, I do: [scrollView setContentOffset:CGPointMake(0,-50) animated:YES]; in viewDidLoad But if I set the content offset to 0,0 in viewDidLoad, I get something that looks like the second screen shot when the view loads. This doesn't make much sense to me because if the content offset is 0,0 I would think the content should begin in the upper right corner of the screen. Does anyone know what could be going on here? Thanks!

When I build and analyze my project on XCode, I obtain a 'warning' on the following line: NSString *contactEmail = (NSString *)ABMultiValueCopyValueAtIndex(emailInfo, 0); The message is: Potencial leak on object allocated on line ... and stored into contactEmail. Is there any error on that line?

  • Overriding properties of child view controller vs setting them via parent view controller

    - by robinjam
    If you want to modify the default behaviour of a View Controller by changing the value of one of its properties, is it considered better form to instantiate the class and set its property directly, or subclass it and override the property? With the former it would become the parent View Controller's responsibility to configure its children, whereas with the latter the children would effectively configure themselves. EDIT: Some more information: The class I am referring to is FetchedTableViewController, a subclass of UITableViewController that I made to display the results of a Core Data fetch operation. There are two places I want to display the results of a fetch, and they each have different fetch requests. I'm trying to decide whether it's better to create a subclass for each one, and override the fetchRequest property, or make it the responsibility of the parent controller to set the fetchRequest property for its children.

  • PLCameraController is not adding in viewcontroller

    - by sujyanarayan
    Hi, I've declared PLCameraContoller instance in my AppDelegate class as:- self.cameraController = [PLCameraController performSelector:@selector(sharedInstance)];[cameraController setDelegate:self]; And I'm accessing it in one of my viewcontroller class as:- del = [[UIApplication sharedApplication] delegate]; UIView previewView = [del.cameraController performSelector:@selector(previewView)]; previewView.frame = CGRectMake(0,0, 320, 480); self.view = previewView; [del.cameraController performSelector:@selector(startPreview)]; [del.cameraController performSelector:@selector(setCameraMode:) withObject:(NSNumber)1]; Where "del" is an instance of my AppDelegate class. But i can see only black background in my viewcontroller view in iphone device. Also if i remove "self" from the appdelegate.m code of cameracontroller it also showing blank. How can i get camera in my view controller? I'm pretty much struggling with it. Thanks in Adv.

  • CLLocationManager class method not calling in iPodTouch

    - by Siddharth
    HI all, I was using a sample code which uses CLLocationManager class to determine the current location of user. when i run this app on iPad i am getting the correct location but when i run the same app on iPod Touch i am getting a blank label i.e nothing is displayed on the label .although wi-fi signal strength is good in both iPod and iPad.The code looks like... - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ int degrees = newLocation.coordinate.latitude; double decimal = fabs(newLocation.coordinate.latitude - degrees); int minutes = decimal * 60; double seconds = decimal * 3600 - minutes * 60; NSString *lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"", degrees, minutes, seconds]; latLabel.text = lat; [latLocationArray addObject:lat]; degrees = newLocation.coordinate.longitude; decimal = fabs(newLocation.coordinate.longitude - degrees); minutes = decimal * 60; seconds = decimal * 3600 - minutes * 60; NSString *longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"", degrees, minutes, seconds]; longLabel.text = longt; [longLocationArray addObject:longt]; }

  • UIButton and UIControlEventState issue

    - by Typeoneerror
    I'm having a very specific "bug" in my iPhone application. I'm setting two images for the highlighted and normal states of a button. It works as expected when you "press" and then "touch up" at a slow pace, but if you click/tap it quickly, there's a noticeable flicker between states. Is this a known bug or am I setting the states incorrectly? Here's the code that creates the buttons: UIImage *normalImage = [[UIImage imageNamed:@"btn-small.png"] stretchableImageWithLeftCapWidth:10.0f topCapHeight:0.0f]; UIImage *highlightedImage = [[UIImage imageNamed:@"btn-small-down.png"] stretchableImageWithLeftCapWidth:10.0f topCapHeight:0.0f]; [self setBackgroundColor:[UIColor clearColor]]; [self setBackgroundImage:normalImage forState:UIControlStateNormal]; [self setBackgroundImage:highlightedImage forState:UIControlStateDisabled]; [self setBackgroundImage:highlightedImage forState:UIControlStateHighlighted]; [self setAdjustsImageWhenDisabled:FALSE]; [self setAdjustsImageWhenHighlighted:FALSE]; When a button is tapped it simply disables itself and enables the other button: - (IBAction)aboutButtonTouched:(id)sender { aboutButton.enabled = FALSE; rulesButton.enabled = TRUE; } - (IBAction)rulesButtonTouched:(id)sender { rulesButton.enabled = FALSE; aboutButton.enabled = TRUE; } Any thoughts on this quick-click flicker?

  • Add UIView Above All Other Views, Including StatusBar

    - by Mike Stead
    I'm wanting to create a view (UIControl) which blocks all input and shows a UIActivityIndicatorView while authenticating a user. The UIActionSheet and UIAlertView both manage to add a black semi-transparent view over the top of all other views to block input and I'd like to do similar. I've tried adding my view to the top UIWindow in the [[UIApplication sharedApplication] windows] array, and while this does place it above the UIKeyboard if it's visible, it doesn't place it over the StatusBar (which makes sense). My next attempt was to extend UIAlertView, remove all of its subviews and set its layer.contents = nil, then add the ActivityIndicator as a subview. This works well, but I can't seem to kill the default bouncy transition of the UIAlertView when you call it to "show". Does anyone have any pointers towards the best way tackle this problem that gives me full control? Oh and I know blocking input is not great but I do ensure it's for a short period of time and it has the benefit of making it clear to the user that their action, which must complete for them to progress, is processing.

  • iPhone: AppStore InAppPurchase Connects in Simulator but Not on Device

    - by riteshkumar1905
    I am having trouble connecting to the AppStore from within my application. Everything runs fine in the Simulator but when I run on device the app cannot connect to the Appstore.

  • Object in Array is not recognised as having "methods"

    - by kevin Mendoza
    I got my application working Awhile back, but after completely and accidentally deleting it, I have tried to create it from square one. unfortunately my rewritten program is a bit cranky; does anyone see or know the possible sources of error? Also, my if statements are acting up. -(void)loadAnnotations { CLLocationCoordinate2D workingCoordinate; iProspectLiteAppDelegate *appDelegate = (iProspectLiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray *mines =[[NSMutableArray alloc] initWithArray:(NSMutableArray *) appDelegate.mines]; BOOL gold = [[NSUserDefaults standardUserDefaults] boolForKey:@"goldControl"]; BOOL silver = [[NSUserDefaults standardUserDefaults] boolForKey:@"silverControl"]; BOOL copper = [[NSUserDefaults standardUserDefaults] boolForKey:@"copperControl"]; for(id mine in mines) { NSLog(@"in the loop"); workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectLiteAnnotation *tempMine = [[iProspectLiteAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTite:[mine mineName]]; if ([[mine commodity] isEqualToString:@"Gold"] && [gold == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeGold]; [mapView addAnnotation:tempMine]; } if([[mine commodity] isEqualToString:@"Silver"] && [silver == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeSilver]; } if([[mine commodity] isEqualToString:@"Copper"] && [copper == YES]) { [tempMine setAnnotationType:iProspectLiteAnnotationTypeCopper]; } } [mines dealloc]; } where the workingCoordinate.latitude = [[mine latitudeInitial] doubleValue], as well as the longitude, and [mine mineName],it says " No '-latitudeInitiallongitudeInitial' method found" or the mineName/LongitudeInitial. also, it complains about : before ] at all the if statement lines. I don't see any errors, do you?
