• can not set the bool value of app setting

  - by user262325

  Hello everyone I use the codes below to read and write a bool value from my application: -(void)SaveAppSetting; {     NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];     bool b=true;     [defaults setBool:b forKey:@"AnyKey"]; [defaults synchronize]; } -(void)LoadAppSetting; {     NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];     bool b=[defaults boolForKey: @"AnyKey"] ; } I found that "LoadAppSetting" worked well, it could get the correct value of item with key "AnyKey". The function "SaveAppSetting" looked like no function, it reported no error, but it can not change value of the item with key "AnyKey". "AnyKey" setting in Setting bundle is item Dictionary Type String PSToggleSwitchSpecifier Title String AnyKey's Title Key String AnyKey DefaultValue Boolean Checked Is there any person met the same problem? Thanks interdev

• Is there a way to set an int to 001

  - by H.aLFaRSi

  i need to set an integer to start from 001 instead of only 1 int iNumber = 001; NSLog(@"%d",iNumber); // this is logging 1 instead of 001 is there a possible way to make it 001 ? [UPDATED] i need this because i`m creating an NSMutableArray from NSUserDefaults, after that I'm sorting the array using NSSortDescriptor. the problem is because i can't set the int to start from 001 the array i sorted like this 0, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9. More Code explained NSString *name = @"Name"; NSUserDefaults *MainArray = [NSUserDefaults standardUserDefaults]; NSString *Temp = [NSString stringWithFormat:@"%@%d", name,MainNumber]; [MainArray setObject:@"test" forKey:Temp]; [MainArray synchronize]; NSLog(@"%@",Temp); MainNumber++; the above code will save it like this : Name1,Name2,Name3.... i need it to be Name001, Name002, Name003 ....... thank you in advance :)

• How to use NSMutableDictionary to store and retrieve data

  - by TechFusion

  I have created Window Based application and tab bar controller as root controller. My objective is to store Text Field data values in one tab bar VC and will be accessible and editable by other VC and also retrievable when application start. I am looking to use NSMutableDictionary class in AppDelegate so that I can access stored Data Values with keys. //TestAppDelegate.h extern NSString *kNamekey ; extern NSString *kUserIDkey ; extern NSString *kPasswordkey ; @interface TestAppDelegate :NSObject{ UIWindow *window; IBOutlet UITabBarController *rootController; NSMutableDictionary *outlineData ; } @property(nonatomic,retain)IBOutlet UIWindow *window; @property(nonatomic,retain)IBOutlet UITabBarController *rootController; @property(nonatomic,retain) NSMutableDictionary *outlineData ; @end //TestAppDelegate.m import "TestAppDelegate.h" NSString *kNamekey =@"Namekey"; NSString *kUserIDkey =@"UserIDkey"; NSString *kPasswordkey =@"Passwordkey"; @implemetation TestAppDelegate @synthesize outlineData ; -(void)applicationDidFinishLaunching:(UIApplication)application { NSMutableDictionary *tempMutableCopy = [[[NSUserDefaults standardUserDefaults] objectForKey:kRestoreLocationKey] mutableCopy]; self.outlineData = tempMutableCopy; [tempMutableCopy release]; if(outlineData == nil){ NSString *NameDefault = NULL; NSString *UserIDdefault= NULL; NSString *Passworddefault= NULL; NSMutableDictionary *appDefaults = [NSMutableDictionary dictionaryWithObjectsAndKeys: NameDefault, kNamekey , UserIDdefault, kUserIDkey , Passworddefault, kPasswordkey , nil]; self.outlineData = appDefaults; [appDefaults release]; } [window addSubview:rootController.view]; [window makeKeyAndVisible]; NSMutableDictionary *savedLocationDict = [NSMutableDictionary dictionaryWithObject:outlineData forKey:kRestoreLocationKey]; [[NSUserDefaults standardUserDefaults] registerDefaults:savedLocationDict]; [[NSUserDefaults standardUserDefaults] synchronize]; } -(void)applicationWillTerminate:(UIApplication *)application { [[NSUserDefaults standardUserDefaults] setObject:outlineData forKey:kRestoreLocationKey]; } @end Here ViewController is ViewController of Navigation Controller which is attached with one tab bar.. I have attached xib file with ViewController //ViewController.h @interface IBOutlet UITextField *Name; IBOutlet UITextField *UserId; IBOutlet UITextField *Password; } @property(retain,nonatomic) IBOutlet UITextField *Name @property(retain,nonatomic) IBOutlet UITextField *UserId; @property(retain,nonatomic) IBOutlet UITextField *Password; -(IBAction)Save:(id)sender; @end Here in ViewController.m, I am storing object values with keys. /ViewController.m -(IBAction)Save:(id)sender{ TestAppDelegate appDelegate = (TestAppDelegate)[[UIApplication sharedApplication] delegate]; [appDelegate.outlineData setObject:Name.text forKey:kNamekey ]; [appDelegate.outlineData setObject:UserId.text forKey:kUserIDkey ]; [appDelegate.outlineData setObject:Password.text forKey:kPasswordkey]; [[NSUserDefaults standardUserDefaults] synchronize]; } I am accessing stored object using following method. -(void)loadData { TabBarAppDelegate *appDelegate = (TabBarAppDelegate *)[[UIApplication sharedApplication] delegate]; Name = [appDelegate.outlineData objectForKey:kNamekey ]; UserId = [appDelegate.outlineData objectForKey:kUserIDkey ]; Password = [appDelegate.outlineData objectForKey:kPasswordkey]; [Name release]; [UserId release]; [Password release]; } I am getting EXEC_BAD_ACCESS in application. Where I am making mistake ? Thanks,

• Display locale language in full

  - by Mihai Fonoage

  Hi, I am getting the user preferred language from the below code: NSUserDefaults* defs = [NSUserDefaults standardUserDefaults]; NSArray* languages = [defs objectForKey:@"AppleLanguages"]; NSString *language = [languages objectAtIndex:0]; This will return something like 'en' for 'English', or 'de' for 'Deutsch'. Is there any way I can automatically get the full language name, i.e. English instead of en? Thanks! Mihai Fonoage

• Best practise - Accessing preferences globally

  - by JK

  User preferences for my app is store in NSUserDefaults. This includes a "theme" preference, which needs to be accessed frequently by multiple classes. I would prefer not to call "[[NSUserDefaults standardUserDefaults] objectForKey:..." repeatedly as it makes for inconcise code and I assume will incur overhead. What is the preferred and most concise method for accessing preferences in any class?

  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?

• iPhone MapKit problems: viewForAnnotation inconsistently setting pinColor?

  - by blackkettle

  Hi, I'm trying setup a map that displays different pin colors depending on the type/class of the location in question. I know this is a pretty common thing to do, but I'm having trouble getting the viewForAnnotation delegate to consistently update/set the pin color. I have a showThisLocation function that basically cycles through a list of AddressAnnotations and then based on the annotation class (bus stop, hospital, etc.) I set an if( myClass == 1){ [defaults setObject:@"1" forKey:@"currPinColor"]; [defaults synchronize]; NSLog(@"Should be %@!", [defaults objectForKey:@"currPinColor"]); } else if( myClass ==2 ){ [defaults setObject:@"2" forKey:@"currPinColor"]; [defaults synchronize]; NSLog(@"Should be %@!", [defaults objectForKey:@"currPinColor"]); } [_mapView addAnnotation:myCurrentAnnotation]; then my viewForAnnotation delegate looks like this, - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation { if( annotation == mapView.userLocation ){ return nil; } NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; MKPinAnnotationView *annView = nil; annView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:@"currentloc"]; if( annView == nil ){ annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; } annView.pinColor = [defaults integerForKey:@"currPinColor"]; NSLog(@"Pin color: %d", [defaults integerForKey:@"currPinColor"]); annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } The problem is that, although the NSLog statements in the "if" block always confirm that the color has been set, the delegate sometimes but not always ends up with the correct color. I've also noticed that what generally happens is that the first search for a new location will set all pins to the last color in the "if" block, but search for the same location again will set the pins to the correct color. I suspect I am not supposed to usen NSUserDefaults in this way, but I also tried to create my own subclass for MKAnnotation which included an additional property "currentPinColor", and while this allowed me to set the "currentPinColor", when I tried to access the "currentPinColor from the delegate method, the compiler complained that it didn't know anything about "currentPinColor in connection with MKAnnotation. Fair enough I guess, but then I tried to revise the delegate method, - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation instead of the default - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation at which point the compiler complained that it didn't know anything about the protocol for MyCustomMKAnnotation in this delegate context. What is the proper way to set the delegate method and/or MyCustomMKAnnotation, or what is the appropriate way to achieve consistent pinColor settings. I'm just about out of ideas for things to try here.

• Problem in In-App purchase-consumable model

  I have created a nonconsumable in app purchase item and now I want to create a consumable in-app purchase by which a user to buy it every time he uses it,and also I want to create a subscription model In-App purchase.

• Memory leak using NSMutableArray in RootViewController called from App Delegate

• Doesn't [UIWindow addSubView:] retain?

  - by Dan Ray

  Check it: NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"Checking login--user value is %@", [defaults valueForKey:@"userID"]); if ([defaults valueForKey:@"userID"] == NULL){ LoginViewController *loginController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; [window addSubview:loginController.view]; [loginController release]; } else { [window addSubview:[navigationController view]]; } Every other place when I put a subview into another view, I release that view after I've done that, because it's now owned by the view it's a subview of. HERE, though, when I do [loginController release], every IBAction on that loginController gets called against a deallocated instance. Commenting out that line makes everything work. I note the difference in approach between my loginController and the navigationController that came with the template; the navigationController is a synthesized property that gets released in -(void)dealloc{ }, so it's still around after being put into window.

• selectedSegmentIndex not updating UISegmentControl

  In my viewDidLoad, I'm retrieving user preferences and updating the settings tab. It is working for editSelection (see code) but the other NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; BOOL editSelection = [userDefaults boolForKey:@"editToggleSwitch"]; editingToggle.selectedSegmentIndex = editSelection; // this is working! bToggle.selectedSegmentIndex = [[userDefaults objectForKey:@"bSegment"] intValue]; In the view, the editingToggle segment is displaying correctly but bToggle is always at 0? NSLog shows that the data was saved and retrieved correctly. I've even set bToggle.selectedSegmentIndex = 1; but it still does not reflect correctly in the view? Any ideas?

• checking player prefs from unity in xcode

  - by user313100

  I made a simple scene that has some GUI buttons in Unity. When you press a button it will set a player preference to 1. I have a button for facebook, twitter and a store. In XCode, when the value hits 1, it switches to a new window with facebook, twitter or the store. My problem is that when I try and retrieve the player preferences in XCode, they always come up as null. To compound my confusion, my code seems to respond to the switch to 1 and it switches to the new window when the value hits 1. Any ideas why it manages to switch to the other window and why I am getting null values? - (void) applicationDidFinishLaunching:(UIApplication*)application { printf_console("-> applicationDidFinishLaunching()\n"); NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:0 forKey:@"Store"]; [userDefaults setInteger:0 forKey:@"Facebook"]; [userDefaults setInteger:0 forKey:@"Twitter"]; _storeWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _facebookWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _twitterWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; viewControllerSK = [[SKViewController alloc]initWithNibName:@"SKViewController" bundle:nil]; viewControllerFacebook = [[xutils_exampleViewController alloc]initWithNibName:@"FacebookViewController" bundle:nil]; viewControllerTwitter = [[xutils_exampleViewController2 alloc]initWithNibName:@"TwitterViewController" bundle:nil]; [_storeWindow addSubview:viewControllerSK.view]; [_facebookWindow addSubview:viewControllerFacebook.view]; [_twitterWindow addSubview:viewControllerTwitter.view]; [SKStoreManager sharedManager]; [self startUnity:application]; } - (void) applicationDidBecomeActive:(UIApplication*)application { printf_console("-> applicationDidBecomeActive()\n"); if (gDidResignActive == true) { UnitySetAudioSessionActive(true); UnityPause(false); } gDidResignActive = false; [self newTimer]; } - (void) applicationWillResignActive:(UIApplication*)application { printf_console("-> applicationDidResignActive()\n"); UnitySetAudioSessionActive(false); UnityPause(true); gDidResignActive = true; } - (void) applicationDidReceiveMemoryWarning:(UIApplication*)application { printf_console("WARNING -> applicationDidReceiveMemoryWarning()\n"); } - (void) applicationWillTerminate:(UIApplication*)application { printf_console("-> applicationWillTerminate()\n"); UnityCleanup(); } -(void)newTimer { NSTimer *theTimer = [self getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; } -(NSTimer *)getTimer { NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(onLoop) userInfo:nil repeats:YES]; return [theTimer autorelease]; } -(void)onLoop { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; //NSLog(@"FB: %@", [userDefaults integerForKey:@"Facebook"]); if ([userDefaults integerForKey:@"Store"] != 1 && [userDefaults integerForKey:@"Facebook"] != 1 && [userDefaults integerForKey:@"Twitter"] != 1) { UnityPause(FALSE); _window.hidden = NO; _storeWindow.hidden = YES; _facebookWindow.hidden = YES; _twitterWindow.hidden = YES; [_window makeKeyWindow]; } if ([userDefaults integerForKey:@"Store"] == 1) { UnityPause(TRUE); _storeWindow.hidden = NO; _window.hidden = YES; [_storeWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Facebook"] == 1) { UnityPause(TRUE); _facebookWindow.hidden = NO; _window.hidden = YES; [_facebookWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Twitter"] == 1) { UnityPause(TRUE); _twitterWindow.hidden = NO; _window.hidden = YES; [_twitterWindow makeKeyWindow]; } } -(void) dealloc { DestroySurface(&_surface); [_context release]; _context = nil; [_window release]; [_storeWindow release]; [_facebookWindow release]; [_twitterWindow release]; [viewControllerSK release]; [viewControllerFacebook release]; [viewControllerTwitter release]; [super dealloc]; }

My guess is that it has to do with the CLLocation *location line.

So I'm asking you, what's the error in this peace of code, that should be very plain and easy? int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // -imagePath // -filePath NSUserDefaults *args = [NSUserDefaults standardUserDefaults]; NSString *soundPath = [args stringForKey:@"imagePath"]; NSString *filePath = [args stringForKey:@"filePath"]; BOOL worked = [[NSWorkspace sharedWorkspace] setIcon:[[NSImage alloc] initWithContentsOfFile:soundPath] forFile:filePath options:0]; NSLog(@"Worked: %i",worked); [pool release]; return 0; }

• should variable be released or not? iphone-sdk

  - by psebos

  Hi, I have the following piece of code from a book. There is this function loadPrefs where the NSString *userTimeZone is being released before the end of the function. Why? The string was not created with alloc and I assume that the stringForKey function returns an autoreleased NSString. Is this an error or am I missing something? Is it an error in the book? (I new into objective-C) In the documentation for stringForKey the only thing it mentions is: Special Considerations The returned string is immutable, even if the value you originally set was a mutable string. The code: - (void) loadPrefs { timeZoneName = DefaultTimeZonePref; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSString *userTimeZone = [defaults stringForKey: TimeZonePrefKey]; if (userTimeZone != NULL) timeZoneName = userTimeZone; [userTimeZone release]; show24Hour = [defaults boolForKey:TwentyFourHourPrefKey]; } Thanks!!!!
