  • Can you manually add to an iPhone/iPad Navigation Bar a back button item?

    - by MikeN
    I have a reference to a "UIBarButtonItem", is there a way I can add a custom "Back Navigation Button" to that item when it is not part of a Navigation based view? I can add a left button: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Custom Back" style:UIBarButtonItemStylePlain target:self action:@selector(backAction:)]; menuItem.backBarButtonItem = backButton; //This doesn't seem to work. menuItem.popOverNavigationItem.leftBarButtonItem = backButton; //This shows a normal button So how could I make the leftmost button look like a back navigation button?

  • How to solve a deallocated connection in iPhone SDK 3.1.3? - Streams - CFSockets

    - by Christian
    Hi everyone, Debugging my implementation I found a memory leak issue. I know where is the issue, I tried to solve it but sadly without success. I will try to explain you, maybe someone of you can help with this. First I have two classes involved in the issue, the publish class (where publishing the service and socket configuration is done) and the connection (where the socket binding and the streams configuration is done). The main issue is in the connection via native socket. In the 'publish' class the "server" accepts a connection with a callback. The callback has the native-socket information. Then, a connection with native-socket information is created. Next, the socket binding and the streams configuration is done. When those actions are successful the instance of the connection is saved in a mutable array. Thus, the connection is established. static void AcceptCallback(CFSocketRef socket, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) { Publish *rePoint = (Publish *)info; if ( type != kCFSocketAcceptCallBack) { return; } CFSocketNativeHandle nativeSocketHandle = *((CFSocketNativeHandle *)data); NSLog(@"The AcceptCallback was called, a connection request arrived to the server"); [rePoint handleNewNativeSocket:nativeSocketHandle]; } - (void)handleNewNativeSocket:(CFSocketNativeHandle)nativeSocketHandle{ Connection *connection = [[[Connection alloc] initWithNativeSocketHandle:nativeSocketHandle] autorelease]; // Create the connection if (connection == nil) { close(nativeSocketHandle); return; } NSLog(@"The connection from the server was created now try to connect"); if ( ! [connection connect]) { [connection close]; return; } [clients addObject:connection]; //save the connection trying to avoid the deallocation } The next step is receive the information from the client, thus a read-stream callback is triggered with the information of the established connection. But when the callback-handler tries to use this connection the error occurs, it says that such connection is deallocated. The issue here is that I don't know where/when the connection is deallocated and how to know it. I am using the debugger, but after some trials, I don't see more info. void myReadStreamCallBack (CFReadStreamRef stream, CFStreamEventType eventType, void *info) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; // The error -[Connection retain]: message sent to deallocated instance 0x1f5ef0 (Where 0x1f5ef0 is the reference to the established connection) [handlerEv readStreamHandleEvent:stream andEvent:eventType]; [pool drain]; } void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *p = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [[(Connection *)info retain] autorelease]; //Sometimes the error also happens here, I tried without the pool, but it doesn't help neither. [handlerEv writeStreamHandleEvent:eventType]; [p drain]; } Something strange is that when I run the debugger(with breakpoints) everything goes well, the connection is not deallocated and the callbacks work fine and the server is able to receive the message. I will appreciate any hint!

  • iPhone SDK Core Data: Fetch all entities with a nil relationship?

    - by Harkonian
    I have a core data project that has Books and Authors. In the data model Authors has a to-many relationship to Books and Books has a 1-1 relationship with Authors. I'm trying to pull all Books that do not have an Author. No matter how I try it, no results are returned. In my predicate I've also tried = NIL, == nil, == NIL. Any suggestions would be appreciated. // fetch all books without authors - (NSMutableArray *)fetchOrphanedBooks { NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Book" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:20]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"author = nil"]; [fetchRequest setPredicate:predicate]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSString *sectionKey = @"name";//nil; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:sectionKey cacheName:nil]; BOOL success = [aFetchedResultsController performFetch:nil]; NSMutableArray *orphans = nil; // this is always 0 NSLog(@"Orphans found: %i", aFetchedResultsController.fetchedObjects.count); if (aFetchedResultsController.fetchedObjects.count > 0) { orphans = [[NSMutableArray alloc] init]; for (Note *note in aFetchedResultsController.fetchedObjects) { if (note.subject == nil) { [orphans addObject:note]; } } } [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; return [orphans autorelease]; }

  • Using in app purchase to unlock features vs. using free & paid app versions for iPhone

    - by yabada
    I have an app that I was going to release as a free (lite) version with some of the total functionality and a paid full version with advanced functionality. Now, with in app purchase for free apps I am thinking of going that route with the ability to unlock features as needed. I'm not talking about a trial version that expires.I want people to be able to try out the app and get an idea of the interface and functionality before deciding to purchase the full functionality of each major section of the app, basically. Here's an analogy of what my app would be like. Let's say you have a cooking app that teaches you to cook in different styles. There could be major section for French, Italian, and Chinese. Each section could have some rudiments unlocked in the free app so users can see the UI and basics of the functionality. Then, the user could decide to purchase each major section (or not) individually with in app purchase or buy the full versioned app (with the free/paid model). One concern I have with offering a free app with in app purchase would be with feedback. I would be very clear in my description in the app store that there is in app purchase for full features but I'm worried that less serious users could/would leave negative feedback. I suppose that's always a risk but curious about any experience with this. It also seems that it could be a whole lot more complicated keeping track of what portions of the app are locked and unlocked with in app purchase. I know I'd have to have all the code for the full functionality and "lock" the portions that haven't been purchased. How do people usually lock portions of their code? I'm not talking about the process of purchasing (I've read the In App Purchase Programming Guide) but after the purchase has been made. Would I just keep track of what the user has purchased and put conditionals on the sections that are initially locked? Or is there another way to do this as well? My instinct is for the in app purchase (particularly since users could purchase the major sections that they want individually).

  • Signing in to Twitter from iPhone - is the cake poisoned?

    - by Tristan
    Hi there, I'm using MGTwitterEngine to add Twitter functionality to my app. It's very easy to simply prompt the user for a username and password and then start posting. Strangely, however, I've noticed other apps (eg Foursquare and Brightkite) require you to visit their website to associate your Twitter account with your foursquare/brightkite/whatever account. Why do they do it this way? Is there a reason why my app shouldn't prompt the user for a Twitter username and password, even though it would be so easy? Thanks a bunch! Tristan

It is starting to become repetitive across my App and smells of code duplication ;) However, I wonder what is the best aproach here.

  • How can I detect short phone numbers in iPhone web views?

    - by Pedro
    G'day All Most Australian phone numbers are 10 digits with the 1st 2 optional if they're a local area code. For those setting... viewer.dataDetectorTypes = UIDataDetectorTypePhoneNumber; on a web view works. We also have a range of 6 digit phone numbers (usually written xxx xxx or xx xxxx) which aren't being detected in my app. Is there a way to detect those phone numbers as well? Cheers & TIA, Pedro :)

  • Loading data from a dictionary of dictionaries into an array in Objective C for an iphone app

    - by Kat
    I have a UINavigationController consisting of a tableview I want to load some data into. I have a dictionary plist containing Dictionaries for each Train Line which in turn have dictionaries for each station with the relevant information along with one string lineName. I need to collect the station Names keys and add them to an array to populate my table (This is working). The line names are stored as a string in my lines dictionary with the key being "lineName" Root->| | |->TrainLine1(Dictionary)->| | |-> lineName (String) | |-> Station1 (Dictionary) | |-> Station2 (Dictionary) | | |->TrainLine2(Dictionary)->| | |-> lineName (String) | |-> Station1 (Dictionary) | |-> Station2 (Dictionary) Am I going about this the wrong way? Should I reorganise my plist? The code below crashes the app. - (void)viewDidLoad { self.title = @"Train Lines"; NSString *path = [[NSBundle mainBundle] pathForResource:@"lineDetails" ofType:@"plist"]; NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:path]; NSMutableArray *array = [[NSMutableArray alloc] init]; NSMutableArray *lineNameArray = [[NSMutableArray alloc] init]; NSString *key; for (key in dictionary) { NSMutableDictionary *secondDictionary = [NSDictionary dictionaryWithDictionary:[dictionary valueForKey:key]]; [lineNameArray addObject:key]; NSLog(@"Adding this in array:%@", key); [array addObject:[secondDictionary objectForKey:kLineNameKey]]; } self.trainLines = array; self.trainLineKeys = lineNameArray; NSLog(@"Array contents:%@", self.trainLineKeys); [lineNameArray release]; [array release]; [dictionary release]; [super viewDidLoad]; }

  • iPhone landscape navigation back action shows vertical view transition?

    - by Code Shogun
    I have a regular UINavigationController and I push a series of UIViewController into the stack. The view transition for push controller is horizontal animation transition: [self.navigationController pushViewController:controller animated:YES]; However, when I press the Back button on the navigation bar, the view transition animation is vertical (vertically dropping down the previous controller/view). I don't seem to find any way to make this horizontal. This happens only in Landscape mode. Portrait mode the transition all happens as horizontal flip transition. Can anyone shed any light on this? Thanks

  • iPhone - Have the keyboard slide into view from the right like when editing a note in Contacts

    - by Toon Van Acker
    Hello, I'm looking for a way to slide the keyboard into view from the right, like what happens in the Contacts application when you edit a note. My problem is that when I call [someTextView becomeFirstResponder] in viewWillAppear, the keyboard immediatly pops up with no animation. And when I call it in viewDidAppear, the view first slides in from the right (UINavigationController does the sliding), and then the keyboard slides in from the bottom. Is it possible to have the keyboard slide in from the right, together with the view?

  • iPhone OpenGL Splash Screen? How?

    - by Kyle
    My app is based pretty much on the EAGLView in the SDK. It doesn't incorporate a ViewController. Rather it simply inits GL and starts painting immediately.. Currently, my app will load a very small PNG and displays it as quickly as possible. On a 3GS this is rather instant, but on a 3G it can take about 2 seconds. In the latter case of the 3G, the user is looking at a black screen for that time. Is this behavior allowed by Apple? Is there any way to alter this SDK example so that it makes use of 'default.png'? It doesn't seem so straight forward to me. I want my user to see an image as quickly as possible, and I also don't want to be rejected for such a little quirk like this as well. In the guidelines, they encourage you to use default.png for standard applications to show a sort of mockup of the interface while it actually loads. I want to initialize OpenGL, and ALSO display this. This default.png is loaded before the app screen launches. This is EXACLTY what I want to make use of. Any help is appreciated. Thanks!

  • How do I read live camera data on the iPhone (like Microsoft Tag Reader)?

    - by Bill
    While the user is still in UIImagePickerController, I'd like to be able to get a UIImage representation of the image in the camera, make some changes to the image, and then display the altered image instead of the image coming directly from the camera. How can I do this? I tried setting a timer and calling takePicture, but calling it seemed to have no effect. The documentation says: Calling this method while an image is being captured has no effect. You must wait until the associated delegate object receives an imagePickerController:didFinishPickingMediaWithInfo: message before you can capture another picture. So how can I do this? I know that it's possible, since apps like Tag Reader are able to detect when something specific rolls in front of the camera. Thanks!
