• UITableViewController's TableView becomes NULL

  - by Travis

  I have UITableViewController (initiated by the Navigation-based app project template). I am overriding loadView and putting up an alternative view (w/ a UILabel and UIActivityIndicator) to display while the table's contents is loading. When the loading is done, I remove the loading view and try to display the table view but I see that it's NULL. So in the simulator I see my loading view and then when the loading's done the view disappears but my tableview never comes. I'm confused what the difference is between self.view and self.tableView in my UITableViewController and how I can exchagn

• UIButton that cycles through images when clicked

  - by dot

  I have three images that I want to cycle through when clicking on a UIButton. How would I go about doing this? This is what I have so far, but it's not really working. //the images NSString* imageNames[] = {"MyFirstImage", "AnotherImage", whatever else}; int currentImageIndex = 0; and - (IBAction)change{ UIImage* imageToShow = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource: imageNames[currentImageIndex] ofType:@"png"]; if( currentImageIndex++ == sizeof(imageNames)/sizeof(NSString)) //check to see if you hit the last image { currentImageIndex = 0; //start over } } Ideas? Any help will be greatly appreciated! Thanks!

• iPod touch debugging: Error on install/run only if app exists on device already?

  - by Ben

  Hi all, I am using an iPod to test an app. The device is all set up with the right provisioning profiles, etc-- that's not really the issue. But every time I start the app from Xcode on the device, I get the "A signed resource has been added, modified, or deleted." error from the Organizer window. Wait, I know, you think it's a provisioning profile problem. But here's the kicker: if I just delete the app from the iPod (using the main screen) and try again, it works fine. I only get this error when the app is already installed. The other kicker is that this behavior doesn't happen on an iPhone that I have for occasional testing-- on that device, I can start/restart/restart indefinitely. But using the iPod, my compile-run-test cycle is annoyingly slow since I have to manually delete the app each time. Any ideas? I'm using Xcode 3.2.2 (prerelease) FWIW. The iPod has stock OS 3.1.2 on it. Thanks!

• NSXMLParser + encoding="windows-1257"

  - by Moze

  So i'm making small program and it download ziped XML database file that is ~30 MB size (unziped). As I understand there is only way with such big files on iPhone, it's to use NSXMLParser. But that file is encoded with windows-1257 format and NSXMLParser does not eat files like that. What can I do? Is there a way to change file encoding on iphone or make NSXMLParser work with other then UTF8 encoded files?

• Toubleshooting mapkit performance

  - by brettr

  I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

• What is the best way to extend restful_authentication/AuthLogic to support lazy logins by an anonymo

  - by Kevin Elliott

  I'm building an iPhone application that talks to a Ruby on Rails backend. The Ruby on Rails application will also service web users. The restful_authentication plugin is an excellent way to provide quick and customizable user authentication. However, I would like users of the iPhone application to have an account created automatically by the phone's unique identifier ([[UIDevice device] uniqueIdentifier]) stored in a new column. Later, when users are ready to create a username/password, the account will be updated to contain the username and password, leaving the iPhone unique identifier intact. Users should not be able to access the website until they've setup their username/password. They can however, use the iPhone application, since the application can authenticate itself using it's identifier. What is the best way to modify restful_authentication to do this? Create a plugin? Or modify the generated code? What about alternative frameworks, such as AuthLogic. What is the best way to allow iPhones to get a generated auth token locked to their UUID's, but then let the user create a username/password later?

• Sorting array containing strings in objective c

  - by jakob

  Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

• Preserving alpha issues with loaded UIImages - how to avoid discarding alpha values on import?

  - by Peter Hajas

  My application lets the user save/load images with alpha values to the camera roll on the device. I can see in the Photos application that these images are appropriately alpha'd, as alpha'd areas just appear black. However, when I load these images back into the application using the valueForKey:UIImagePickerControllerOriginalImage message to the info dictionary from (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info, the alpha values are turned to just white, making those sections opaque. Is there a way to preserve these alpha values?

• Strange problem with NSMutableArray - Possibly some memory corruption

  - by user210504

  Hi! I am trying to update data in a table view using a NSMutableArray. Quite simple :( What is happening is that I get my data from a NSURLConnection Callback, which I parse and store it in an array and call reload data on the table view. The problem is that when cellForRowAtIndexPath is called back by the framework. The array still shows the correct count of the elements but all string objects I had stored earlier are shown as invalid. Any pointers

• Problem generating APN SSL certificate after submitting to apple store

  - by MikeQ

  I'm having trouble getting Apple to generate an APN SSL certificate for my app ID. I've submitted the application to the Apple store, and it is pending review. I tested the application using an Ad Hoc app ID "${bundle_id}.adHoc" and everything went fine. I submitted to the Apple store with app ID "${bundle_id}.release". Now I want to generate my production APN SSL certificate for use with my release application ID - but the developer portal doesn't want to. When I upload my certificate request, it sits for about a minute before telling me: "We are not able to generate your Profile at this time. Please try again later or try using the Provisioning Portal" Is it impossible to generate your certificate while the application is under review or something? Should I have generated it prior to submission?

• How to efficiently show many Images? (iPhone programming)

  - by Thomas

  In my application I needed something like a particle system so I did the following: While the application initializes I load a UIImage laserImage = [UIImage imageNamed:@"laser.png"]; UIImage *laserImage is declared in the Interface of my Controller. Now every time I need a new particle this code makes one: // add new Laserimage UIImageView *newLaser = [[UIImageView alloc] initWithImage:laserImage]; [newLaser setTag:[model.lasers count]-9]; [newLaser setBounds:CGRectMake(0, 0, 17, 1)]; [newLaser setOpaque:YES]; [self.view addSubview:newLaser]; [newLaser release]; Please notice that the images are only 17px * 1px small and model.lasers is a internal array to do all the calculating seperated from graphical output. So in my main drawing loop I set all the UIImageView's positions to the calculated positions in my model.lasers array: for (int i = 0; i < [model.lasers count]; i++) { [[self.view viewWithTag:i+10] setCenter:[[model.lasers objectAtIndex:i] pos]]; } I incremented the tags by 10 because the default is 0 and I don't want to move all the views with the default tag. So the animation looks fine with about 10 - 20 images but really gets slow when working with about 60 images. So my question is: Is there any way to optimize this without starting over in OpenGl ES? Thank you very much and sorry for my english! Greetings from Germany, Thomas

• Problems with testing in app purchases

  - by sashaeve

  I am trying to test my application with in app purchases. I created features, test user, logged out from iTunes on the iPhone and used developer certificate. Load app from XCode in debug mode. When I click "Buy" button I pass all checks for internet availability, canMakePayments and call SKPayment *payment = [SKPayment paymentWithProductIdentifier:featureId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; But all what I see is a pending view and after some minutes it failed in - (void) failedTransaction: (SKPaymentTransaction *)transaction { if (transaction.error.code != SKErrorPaymentCancelled) { NSLog(@"failedTransaction"); } [[MKStoreManager sharedManager] paymentCanceled]; [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; } Please advice in what direction I should go to figure out the problem and what else I should check. P.S. All related questions on SO were checked with no luck.

• Can i openly speculate based on App rejection that the iPad has xxx MB of memory?

  - by GamingHorror

  If i were to calculate the iPad's amount of RAM based on just the one fact that my iPad App got rejected due to memory warnings twice, and me fixing it, would this violate the developer NDA? Obviously i know how much memory my App uses, how much the iPhone OS is likely to use and estimate the amount reserved for video memory, then i can deduct from that that the iPad has xxx MB of memory. I just wonder if i can say that number publicly without violating any NDA?

• How can I fix this NavigationController and UIToolbar offset issue in Objective-C?

  - by editor

  I'm adding a couple of buttons to an already-existing NavigationController. The two buttons are added to a UIView, which is pushed onto the NavigationItem. The buttons stop and reload a UIWebView. Problem is that there's a slight offset issue that is making it all look pretty ugly. I wish I could set the UIToolbar to transparent or clear background but that doesn't seem to be an option. Can't seem to use negative offsets either. I've got color matching, but if you look closely there's 1px or 2px of highlighting up top that's causing a visual mismatch and then a slight offset at the bottom. Some relevant code below (based on this, inbound Googlers). What are my options to resolve this? // create a toolbar for the buttons UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 45)]; [toolbar setBarStyle: UIBarStyleDefault]; UIColor *colorForBar = [[UIColor alloc] initWithRed:.72 green:0 blue:0 alpha:0]; toolbar.tintColor = colorForBar; [colorForBar release]; //[toolbar setTranslucent:YES]; // create an array for the buttons NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3]; // create a standard reload button UIBarButtonItem *reloadButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(reload)]; reloadButton.style = UIBarButtonItemStyleBordered; [buttons addObject:reloadButton]; [reloadButton release]; // create a spacer between the buttons UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; [buttons addObject:spacer]; [spacer release]; // create a standard delete button with the trash icon UIBarButtonItem *stopButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemStop target:self action:@selector(stopLoading)]; stopButton.style = UIBarButtonItemStyleBordered; [buttons addObject:stopButton]; [stopButton release]; // put the buttons in the toolbar and release them [toolbar setItems:buttons animated:NO]; [buttons release]; // place the toolbar into the navigation bar self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar]; [toolbar release];

• Animating removeFromSuperview

  - by brettr

  I'd like to animate the transition from a subview back to the super view. I display the subview using: [UIView beginAnimations:@"curlup" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [self.view addSubview:self.mysubview.view]; [UIView commitAnimations]; The above works fine. It's going back to the super view that I don't get any animation: [UIView beginAnimations:@"curldown" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [self.view removeFromSuperview]; [UIView commitAnimations]; Is there something different I should be doing to get the subview to animate when removed?

So, in essence, I am trying to access the photo used by contacts database for a person's phone number or email address. - Is there a way for me to do this? Any help is appreciated.
