  • detecting when nav controller popped to root

    - by phil swenson
    Here is my code: SignupController* signupController = [[SignupController alloc] initWithNibName:@"SignupController" bundle:nil]; [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; self.navigationController.title = @"MyNavController"; [self.navigationController pushViewController:signupController animated:YES]; [signupController release]; Unfortunately for me calling pushViewController is not synchronous, so the next line ([signupController release]) is executed immediately. I need to detect hen the signupController has popped back to the root so I can take the data from the signup controller and do a registration or login. Any ideas? Thanks

  • How to programaticly access min and Max values defined in a core-data model designed with XCode ?

    - by Xav
    I was expecting to find that in the NSAttributeDescription class, but only the default value is there. Behind the scene I tought a validationPredicate was created but trying to reach it using NSDictionary* dico= [[myManagedObject entity] propertiesByName]; NSAttributeDescription* attributeDescription=[dico objectForKey:attributeKey]; for (NSString* string in [attributeDescription validationWarnings]) just get me nowhere, no validationWarnings, no validationPredicates... any thoughts on this ? Edit1: It seems that getting the entity straight from the managedObject doesn't give you the full picture. Getting the Entity from the NSManagedObjectModel permits to reach the validationWarnings & validationPredicates...

  • Generating an NSDictionary from an SQL statement.

    - by Ed Wist
    I am trying to generate an NSDictonary that can be used to populate a listview with data I retrieved from an SQL statement. when I go to create an array and add them it adds the arrays for ALL my keys and not just for the current key. I've tried a removeAllObjects on the array but for some reason that destroys ALL my data that I already put in the dictionary. //open the database if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { const char *sql = "select alphaID, word from words order by word"; sqlite3_stmt *selectStatement; //prepare the select statement int returnValue = sqlite3_prepare_v2(database, sql, -1, &selectStatement, NULL); if(returnValue == SQLITE_OK) { NSMutableArray *NameArray = [[NSMutableArray alloc] init]; NSString *alphaTemp = [[NSString alloc] init]; //loop all the rows returned by the query. while(sqlite3_step(selectStatement) == SQLITE_ROW) { NSString *currentAlpha = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 1)]; NSString *definitionName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)]; if (alphaTemp == nil){ alphaTemp = currentAlpha; } if ([alphaTemp isEqualToString:(NSString *)currentAlpha]) { [NameArray addObject:definitionName]; } else if (alphaTemp != (NSString *)currentAlpha) { [self.words setObject:NameArray forKey:currentAlpha]; [NameArray removeAllObjects]; [NameArray addObject:definitionName]; } } } The Statement above adds all the "keys" but then removes all the array elements for all keys. if I take out the removeAllKeys it adds ALL the array elements for ALL keys. I don't want this I want it to add the array elements FOR the specific key then move on to the next key. in the end I want a NSDictonary with A (array) Alpha (string) Apple (string) B (array) Beta (string) Ball (string) C (array) Code (string) ...

  • Core Data NSFetchedResultsController sorting in certain sequence

    - by Moze
    I'm writing iphone app that has UITableView and uses Core Data. Data in UITableView is shown using NSFetchedResultsController. I use NSPredicate operator "IN" to fetch only needed entries. NSArray *filterArray = [NSArray arrayWithObjects:@"789", @"963", @"445", @"198", nil]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"id IN %@", filterArray]; Now the problem is that I need to show entries in same sequence they are in filterArray. How can I do it? How I can create NSSortDescriptor that would sort all entries in that way? I tried without sort descriptor, but I get error that NSFetchedResultsController needs sortDescriptor to be set.

  • unclear use of @property in window app using core data

    - by Matt
    Looking through a Window based application ive used to experiment with as a way of getting my head around core data, ive noticed that the appdelegate has the following code myAppDelegate.h #import <UIKit/UIKit.h> #import <CoreData/CoreData.h> @interface iCaptureFreeAppDelegate : NSObject <UIApplicationDelegate> { NSManagedObjectModel *managedObjectModel; NSManagedObjectContext *managedObjectContext; NSPersistentStoreCoordinator *persistentStoreCoordinator; UIWindow *window; UITabBarController *tabBarController; } myAppDelegate.m #import "myAppDelegate.h" @interface iCaptureFreeAppDelegate (PrivateCoreDataStack) @property (nonatomic, retain, readonly) NSManagedObjectModel *managedObjectModel; @property (nonatomic, retain) NSManagedObjectContext *managedObjectContext; @property (nonatomic, retain, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator; @end @implementation iCaptureFreeAppDelegate @synthesize window, tabBarController; // code .... // - (NSManagedObjectContext *) managedObjectContext { } - (NSManagedObjectModel *)managedObjectModel { } - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { } // etc..... i want to understand a few things about what this project is doing why the properties in the category declaration? (if i delete the privateCoreDataStack category everything still works...) why the properties appear to be linked with the methods in the implementation ... managedObjectContext {} etc why the members in the .h file have the same name as the properties and the methods why code completion lets me use dot '.' to access the members but then fails on compilation say it cant find a getter thanks !

  • Create an Edit view similar to Contacts App

    - by Daniel Granger
    I have an edit view in my app which is a instance of UITableViewController and contains one cell with a textfield in a grouped table. At the moment this cell is at the top of the screen and is firstResponder so they keyboard is visible as well. But in all the Apples apps like the Contacts App when you edit a piece of information like an Email it buts both of its rows in the middle between the Nav Bar and the Keyboard not at the top of the screen. How do I achieve this effect? Many Thanks

  • Disable link in UIWebView in appearance and function

    - by Peter
    Hello, I wish to disable the href links on a UIWebView. First, I want the look of the link to change so the user doesn't think it is clickable. Second, I want the actual link to not be able to be tapped. I do not want to try webView:shouldStartLoadWithRequest:navigationType: since that not change the appearance of my links. I found this answer: Disabling visible links in UIWebView But the above hasn't worked for me. This is my code: NSString* s=[[NSString alloc] initWithFormat:@"for (a in document.getElementsByTagName(\"a\")) {a.href = \"\";}"]; [myWebView stringByEvaluatingJavaScriptFromString:s]; I've been working on this for hours, any suggestions are appreciated! Thanks!

  • Can we use union of two sqlite databases with same tables for Core Data?

    - by Tofrizer
    Hi All, I have an iPhone Core Data app with a pre-populated sqlite "baseline" database. Can I add a second smaller sqlite database with the same tables as my pre-populated "baseline" database but with additional / complementary data such that Core Data will happily union the data from both databases and, ultimately, present to me as if it was all a single data source? Idea that I had is: 1) the "baseline" database never changes. 2) I can download the smaller "complementary" sqlite database for additional data as and when I need to (I'm assuming downloading sqlite database is allowed, please comment if otherwise). 3) Core Data is then able to union data from 1 & 2. I can then reference this unified data by calling my defined Core Data managed object model. Hope this makes sense. Thanks in advance.

  • How to invert arrow image placed before the first cell when tableview cells are swiped beyond first

    - by neha
    Hi all, In my application, I need to add this functionality that there should be an arrow image upside down placed before first cell and some text like "Pull down to refresh" and when user pulls the table beyond this then this arrow gets inverted and text changes to "Release to refresh" and when the user releases his finger, the data is refreshed and rows get added to that point So now this initial arrow and text moves upwards before the first cell again. Can anybody tell me wheather there's any event that does this? Or else which event I need to capture in order to add this functionality? Thanks in advance.

  • Store Observer not being called always

    - by Nixarn
    Has anyone else here experienced problems with their Store Observer class not being called always when the user for instance cancels a request (or purchases something) We just had our update that brought in app purchases go live last night, and before that we had obviously tested everything tons of times against the Sandbox and everything was working fine. Now however, when the update went live in a real environment we keep getting issues with the store. For instance, in a freshly booted iPhone / iPod, the first time you run the app, if you then try to make a purchase and then immediately cancel it from the first dialog, it seems as if the callback for the cancel is not getting called. If you then restart the app it seems as if it always works after that, or at least. Same thing with other callbacks, seems as if our store observer isn't listening as the callbacks aren't being registered on the phone. One example of this is if you purchase something, then nothing will happen (if this is the first time the app is launched at least). You get the purchase successful dialog from the app store but it seems as if our own code isn't called. If you then quit the app and restart it the callback gets called. Same problem happens if you for instance try to start a request to download all previous purchases and then immediately cancel it as the first dialog pops up, if you do that then the callback for a failed restore is not called, until you then restart the app and try it again, then it always seems to work. The way we have implemented our store observer is by creating a custom class that's implements the SKPaymentTransactionObserver interface. @interface StoreObserver : NSObject<SKPaymentTransactionObserver> In the class we have implemented the following methods: - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions - (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error The way our restore process works is that if you tap on the button that allows you to download all we simply run the restoreCompletedTransactions code as follows: [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]; However, the callback, restoreCompletedTransactionsFailedWithError, which has been implemented in the store observer, does not always get called when we try to cancel the request. This happens when you boot the iPhone / iPod and try this for the first time. If you after that restart the app everything works fine. The StoreObserver class is created when our app is launched, just by running the following code: pStoreObserver = [[StoreObserver alloc] init]; [[SKPaymentQueue defaultQueue] addTransactionObserver:pStoreObserver]; Has anyone else had any similar experiences? Or does anyone have any suggestions on how to solve this? As I said, in the sandbox environment everything was working fine, no issues whatsoever, but now once it's gone live we're experiencing these.

  • Load view when button is clicked in Xcodes Storyboard

    I just started to use Storyboard in Xcode. I have a starting view that has some buttons inside. Is there a way to load a special view when a button is clicked? I only found this workaround: -(IBAction)loadRegistration:(id)sender { // load registration controller UIStoryboard *storyboard = self.storyboard; RegisterController *svc = [storyboard instantiateViewControllerWithIdentifier:@"RegisterController"]; [self presentViewController:svc animated:YES completion:nil]; }
