  • iPhone - In App Purchase questions

    - by diwup
    Hey guys, Merry Christmas. I have two questions on In App Purchase. iAP application process: do I need to submit my iAP items applications, wait for Apple's responses, then build my app accordingly, or, I can just create some iAP items, build them into my app, then after everything's done, submit my binary to Apple? Intermediary currency: on Apple's documentation I found these sentences: "You may not offer items that represent intermediary currency because it is important that users know the specific good or service that they are buying." However, I found a few apps on the App Store offering its users with different kinds of intermediary currency. I'm confused. Is this a gray area in which we developers can play some tricks? Thanks in advance. Di

  • [iphone] method created in a seperate class returns "out of scope"

    - by Dror Sabbag
    Hey, I have created a Class (subclass of NSObject) which will hold all my SQLs/dbConnections etc.. in a seperate viewcontroller, i have instantiated the SQL's class and performed some actions, all went trough OK. but. one of my methods in the SQL's class is a method defined as follows: -(NSString *)queryTable:(NSUInteger *)fieldnum //query from db, and assign the field value into "fieldName" dbEntity = fieldName; [fieldName release]; } sqlite3_finalize(statement); } return dbEntity; } dbEntity is defined as NSString, and i have set it as a nonatoimc-retain property @property (nonatomic,retain) NSString *dbEntity; when ever i call this method out from my viewController and debug step by step, i see that the method is running, it is quering from the db as expected, but when it passes the value into dbEntity the values in dbEntity are suddenly "out of scope" that is... if i browse this specific action: dbEntity = fieldName; i can see values inside fieldName, but see "out of scope" in dbEntity. Why is that?!? what is wrong with dbEntity definitions? Any help will be appriciated.

  • iPhone:(Three20)Unselect (Unhiglight) TTTabItem dynamically?

    - by user187532
    Hello friends, I have four TabBarItem (TTTabItem) in a TabBar (TTTabBar). In one case, i want to remove the TabBarItem selection from any of the four TabBarItems (TTTabItem) . i.e., the complete TabBar will not show any TabBarItems selected. Can i achieve it? I tried the following, [_tabBar1 setSelectedTabItem:nil]; But it is crashing. Could someone guide me to resolve this? I need help urgently. (OR) If we clicked on one TabBarItem(TTTabItem), then again clicking on same TabBarItem(TTTabItem) will not call/execute anything right. Can i make it always clicking on a TabBarItem, should call "(void)tabBar: (UITabBar *)tabBar didSelectItem:(UITabBarItem *)item" (or) any other relevant system functions? I need your helps urgently, could someone guide me for my issue? Thank you.

  • iPhone - Create not persistant entities in core data

    - by ncohen
    Hi everyone, I would like to use entity objects but not store them... I read that I could create them like this: myElement = (Element *)[NSEntityDescription insertNewObjectForEntityForName:@"Element" inManagedObjectContext:managedObjectContext]; And right after that remove them: [managedObjectContext deleteObject:myElement]; then I can use my elements: myElement.property1 = @"Hello"; This works pretty well even though I think this is probably not the most optimal way to do it... Then I try to use it in my UITableView... the problem is that the object get released after the initialization. My table becomes empty when I move it! Thanks

  • How to check Internet status in iPhone

    - by Radix
    Hello; I wanted to check whether internet is connected or not using either the SystemConfiguration or the CFNetwork i am not quite sure which one. Then i want to know that if the internet is connected then is it connected through wifi or not. I tried an example where i used the below code -(IBAction) shownetworkStatus { NSURL *url = [NSURL URLWithString:@"www.google.com"]; if (url!=NULL) { lbl.text = @"Connected"; } else { lbl.text = @"notConnected"; } } some say that its not valid as per apple and you have to use the SystemConfiguration Framework, Please let me know what needs to be done. Also i personally think that what i am doing in the above code is not proper as if one day google may also be down due to maintenance or some other factors. Also if you could provide me a link where i could display the name of the WIFI network then it would be really cool. I searched the internet then i got these Reachability.h code which again is a bouncer as i wana learn the concepts not copy paste them Thanks and Regards Radix

Suppose current year is 2018 then I want minimum date 2000 and maximum date 1918. what I have done so far is : NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [gregorian components:NSYearCalendarUnit fromDate:[NSDate date]]; NSInteger year = [components year]; int mindt = year - 18; int maxdt = year -100; // NSDate * MinDate = [components year] - 18; // NSDate * MaxDate = [components year] - 100; // self.datePicker.minimumDate = MinDate; // self.datePicker.maximumDate = MaxDate; but I cant get this integer to my date formate.. pls suggest any way ...

  • iphone dev - loading table content asynchronously

    - by Brian
    My app has a navigation controller which push and pop a series of views. One of the tableViews loads .xml file from URL and it takes 4-5 seconds. If I click the back button on the navigation bar, it will only respond after the content of the table finish loading. Is there an easy way to load the content asynchronously so that the app will still respond to my gesture on the navigation bar? p.s. I search this on the Internet and people are talking about multithreading. I don't know a lot about threads so please be more specific. Thanks in advanced =)

  • iPhone Application failing to come back from sigkill

    - by overscore
    I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

I am using audio-toolbox framework for playing sound. creating audio queue and then playing sounds in loop. I am also playing sound from ipod library using mediaplayer.

  • Possible to alert server to iphone settings change?

    - by DougW
    I'm working on giving our users context-specific PUSH notification settings, similar to what Facebook has in their settings menu. As far as I can tell though, there's no way to actually notify our server of these changes until the user actually launches the app. Is this correct? Is there any mechanism provided for immediately alerting our servers to a settings change?

  • IPhone iOs 5, need help getting my tab bar at the top to work

    - by Patrick
    I wanted to have the tab bar at the top. So i created a new project in XCode. Added a view and then inside that view i added (scrollbar, text and another view). See picture. What i wanted was to have my tab bar at the top. Then in the middle would be the contents from the tab bar and below it a small copyright text. See picture. No idea how to make this correctly. I have tried to create the UITabBarController on the fly and then assign it into the view at the top. (Top white space on the picture dedicated for the tab bar). Here is my code to init the MainWindow. MainWindow.h #import <UIKit/UIKit.h> @class Intro; @interface MainWindow : UIViewController @property (strong, nonatomic) IBOutlet UIScrollView *mainContentFrame; @property (strong, nonatomic) IBOutlet UIView *mainTabBarView; @property (strong, nonatomic) UITabBarController *mainTabBar; @property (nonatomic, strong) Intro *intro; // Trying to get this tab to show in the tab bar @end MainWindow.m #import "MainWindow.h" #import "Intro.h" @interface MainWindow () @end @implementation MainWindow @synthesize mainContentFrame = _mainContentFrame; @synthesize mainTabBarView = _mainTabBarView; @synthesize mainTabBar = _mainTabBar; @synthesize intro = _intro; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { _intro = [[Intro alloc] init]; NSArray *allViews = [[NSArray alloc] initWithObjects:_intro, nil]; [super viewDidLoad]; // Do any additional setup after loading the view. _mainTabBar = [[UITabBarController alloc] init]; [_mainTabBar setViewControllers:allViews]; [_mainTabBarView.window addSubview:_mainTabBar.tabBarController.view]; } - (void)viewDidUnload { [self setMainTabBar:nil]; [self setMainContentFrame:nil]; [self setMainContentFrame:nil]; [super viewDidUnload]; // Release any retained subviews of the main view. } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } @end What am i missing to get this to work? Wanted the content to end up in the scrollview so that all tabs are scrollable.

  • document directory for different iphone app targets

    - by David
    I have two targets for my app which both unarchive serialized objects, however the objects made by the two apps are not compatible. these objects seem to be saved to the same document directory so that one app will try to unarchive the other's objects. how do I get the apps to create separate sandboxes so they do not have access each others' saved objects? or do I need to just have each version create differently named files?

  • iPhone SDK: How to determine keyboard type within a UIKeyboardDidShowNotification?

    - by iPhone Developer
    Hello, I need to know the current keyboard type. I was setting an instance variable in - (BOOL)textFieldShouldBeginEditing:(UITextField *)textField However, testing has shown that this is not always reliable because of the asynchronous nature of notifications. What I am wondering is if anyone can tell me how to determine the current keyboard type within a notification? - (void)keyboardDidShow:(NSNotification *) { // Need way to determine keyboard type here } Thanks.
