  • linking c++ sources in iPhone project

    - by Steve918
    I have a single cpp file added to my iPhone project with a .cpp extension, but I'm seeing errors when linking like: operator new[](unsigned long)", referenced from: ___gxx_personality_sj0", referenced from: I thought as long as I named the cpp files with .cpp or .mm it would do the right thing, do I need to add some linker flags?

  • Distinct Value Array for View Controller Index Using Core Data

    - by b.dot
    Hi, I'm trying to create an index representing the first letter value of each record in a Core Data store to be used in a table view controller. I'm using a snippet of the code from Apple's documentation. I would simply like to produce an array or dictionary of distinct values as the result. My store already has the character defined within each record object. Questions: 1) I'm having a problem understanding NSDictionaryResultType. Where does the resulting dictionary object get received so that I can assign it's keys to the view controller? The code seems to only return an array. 2) If I include the line containing NSDictionaryResultType, I get no returns. 3) I realize that I could do this in a loop, but I'm hoping this will work. Thanks! NSEntityDescription *entity = [NSEntityDescription entityForName:@"People" inManagedObjectContext:managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:entity]; [request setResultType:NSDictionaryResultType]; // This line causes no no results. [request setReturnsDistinctResults:YES]; [request setPropertiesToFetch :[NSArray arrayWithObject:@"alphabetIndex"]]; NSError *error; NSArray *objects = [managedObjectContext executeFetchRequest:request error:&error];

  • How would I add code that would update an online "counter" so I know how many times an iPhone app is

    - by Luis Tovar
    So I have searched for this but not finding anything about it and if I missed it sorry about that. What I am trying to do is see how to go about adding some code to my iphone app that will connect to a php script (if connection available) and update a counter so that I can let my clients know that their app is constantly being used? Also, would apple allow that? Or would my app be denied for doing such a thing? Any help would be great! Thanks in advance.

  • Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. Wh

    - by Kevin
    I'm just playing around with some code. I create an Activity and simply do something like this: long lo = currentTimeMillis(); System.out.println(lo); lo *= 3; System.out.println(lo); SystemClock.setCurrentTimeMillis(lo); System.out.println( currentTimeMillis() ); Yes, in my AndroidManifest.xml, I've added: <uses-permission android:name="android.permission.SET_TIME"></uses-permission> <uses-permission android:name="android.permission.SET_TIME_ZONE"></uses-permission> Nothing changes. The SystemClock is never reset...it just keeps on ticking. The error that I'm getting just says that the permission "SET_TIME" was not granted to the program. Protection level 3. The permissions are there...and in the API for 2.2 it says that this feature is supported now. I have no idea what I'm doing wrong. If android.content.Intent; comes into play, please explain. I don't really understand what the idea behind intents! Thanks for any help!

  • Why would a "view" object in Interface Builder prevent my didFinishLaunchingWithOptions method from

    - by BeachRunnerJoe
    You may have already come across some of my other questions related to question, but I was having an issue with a SplitView iPad app where my application:didFinishLaunchingWithOptions method stopped executing after I went into Interface Builder and changed around the structure of my apps interface. I couldn't figure out what was preventing my didFinishLauchingWithOptions method from executing, but then I removed a "view" object I had in my view heirarchy (shown below) and suddenly my didFinishLauchingWithOptions method started executing again. I've moved passed it now, but I'm still unclear why that would cause the problem. Any ideas why that "view" object would prevent the didFinishLaunchingWithOptions method from executing?

    - by user128647
    I want to show my custom UIView(.Xib View) to appear when user tabbed on pins (not apple's callOutBubble) and in that UIView there should be a button which fires an IBAction on touched down event. Therefore i have added an AddObserver method to MKAnnotationView. which responds to touch events over pin in MKMapView. But i have also added 3 buttons over that XIB view, which have also assined IBActions. But when i run application, Buttons in Customized Annotation view are not responding to IBAction (Touch Down)? Why this happens ?? What is the solution for that??? I need to have called some method, when those 3 buttons tabbed. Thanks

  • Resizing a UIView - expanding the top

    - by Mongus Pong
    I have a UIView inside of a UIScrollView that I want to resize. I can increase the height easily by : CGRect frame = self.drawinView.frame; frame.size.height += 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(frame.size.width, frame.size.height); And all is good. The above code will create a new area of the view at the bottom of the view that I can fill out. Now when I resize the view, I only want to be repainting the new portion of the view that has just been created. I dont want to have to repaint the whole view. However! I have run into difficulty when I need to expand the top of the view. Doing : CGRect frame = self.drawinView.frame; frame.origin.y -= 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(500, 600); does not work. How can I do this without having to repaint the entire view?

  • Saving data in custom class via AppDelegate

    - by redspike
    I can't seem to save data to a custom instance object in my AppDelegate. My custom class is very simple and is as follows: Person.h ... @interface Person : NSObject { int _age; } - (void) setAge: (int) age; - (int) age; @end Person.m #import "Person.h" @implementation Person - (void) setAge:(int) age { _age = age; } - (int) age { return _age; } @end I then create an instance of Person in the AppDelegate class: AppDelegate.h @class Person; @interface AccuTaxAppDelegate : NSObject <UIApplicationDelegate> { ... Person *person; } ... @property (nonatomic, retain) Person *person; @end AppDelegate.m ... #import "Person.h" @implementation AccuTaxAppDelegate ... @synthesize person; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } - (void)applicationWillTerminate:(UIApplication *)application { // Save data if appropriate } #pragma mark - #pragma mark Memory management - (void)dealloc { [navigationController release]; [window release]; [person release]; [super dealloc]; } @end Finally, in my ViewController code I grab a handle on AppDelegate and then grab the person instance, but when I try to save the age it doesn't seem to work: MyViewController ... - (void)textFieldDidEndEditing:(UITextField *)textField { NSString *textAge = [textField text]; int age = [textAge intValue]; NSLog(@"Age from text field::%i", age); AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate; Person *myPerson = (Person *)[appDelegate person]; NSLog(@"Age before setting: %i", [myPerson age]); [myPerson setAge:age]; NSLog(@"Age after setting: %i", [myPerson age]); [textAge release]; } ... The output of the above NSLogs are: [Session started at 2010-05-04 18:29:22 +0100.] 2010-05-04 18:29:28.260 AccuTax[16235:207] Age in text field:25 2010-05-04 18:29:28.262 AccuTax[16235:207] Age before setting: 0 2010-05-04 18:29:28.263 AccuTax[16235:207] Age after setting: 0 Any ideas why 'age' isn't being stored? I'm relatively new to Obj-C so please forgive me if I'm missing something very simple!

  • Most efficient way to download media files from a server from within an iPhone app.

    - by nikki
    Hi, I have an iPhone application which contains a lot of media files, so far we have been able to keep the size of the iPhone app to less than 20 MB. We add new content with new updates, it would be difficult to keep the app size within the 20 MB limit. The right thing to do here would be to fetch the files on demand from a media/web server. If you have any pointers on how to go about doing this, please suggest. What we would need is to fetch the media files (.jpg/.png images ) on demand when the user taps on a small thumbnail for the image. Are there existing frameworks/servers that provide such services to iPhone clients. Thanks.
