  • Struggling with a loop

    - by Emil
    Hey. I am trying to make an integer match another integer by adding a number to one of them. I have tried several loop types, but none has worked. Take a look at the code: int favoriteLoop = [favoriteThing intValue]; if (favoriteLoop != [[[array objectAtIndex:favoriteLoop] description] intValue]){ NSLog(@"%d", [[[array objectAtIndex:favoriteLoop] description] intValue]); int favTemp = favoriteLoop; for (int x = favTemp; (favoriteLoop == [[[array objectAtIndex:favoriteLoop] description] intValue]); x++) { NSLog(@"Still not there.."); } } Could anyone help me clear up this mess? It just won't work! Could it have something to do with it allready being inside a for-loop?

  • How to call another class's method from my app delegate

    - by Jared
    I have an application that utilizes UILocalNotifications to pop-up UIAlertViews. When the notification fires, the user chooses to go into the app, and this method is called from my app delegate: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...} Where I can handle it and where I also prompt another alertview for more information. So when the app launches, it is displaying view A, and then the alertview pops up and prompts for input. This alertview, however, is originating from my app delegate. I need to be able to reload view A when the user hits Yes/No on the alertview. How can I do that from within my app delegate? Any help is appreciated!!

  • Modal View Does Not Appear in Center in Horizontal Orientation

    - by Sheehan Alam
    I have a UIPresentationFormSheet (contains a textview) that appears in the center of the screen when I am in vertical orientation. When I dismiss the modal view, it disappears fine. When I am in horizontal orientation my modal view does not appear in the center of the screen. I have to dismiss my keyboard for the modal view to appear in the center. [self presentModalViewController:composeTweetController animated:TRUE]; When I dismiss the modal view in horizontal orientation the app automatically switches to vertical orientation. -(void)dismissComposeTweetView{ [self dismissModalViewControllerAnimated:TRUE]; } I want the following to happen: Modal view should appear in the center in horizontal orientation Modal view should disappear without switching to vertical orientation

  • pointer being freed was not allocated

    - by kudorgyozo
    Hello i have the following error: malloc: * error for object 0x2087000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I have no idea what object that is. I don't know how to find it. Can anybody explain to me how (and where) to use malloc_history. I have set a breakpoint in malloc_error_break but i couldn't find out what object is at that address. I receive this after removing an object from an nsmutablearray and popping a view controller manually. If I comment out the line [reviewUpload.images removeObject: self.reviewUploadImg] it doesn't give me the error but of course it's not useful for me like that. - (void) removeImage { debugLog(@"reviewUploadImg %@", self.reviewUploadImg); debugLog(@"reviewUpload %@", self.reviewUpload); debugLog(@"reviewUploadImg thumb %@", self.reviewUploadImg.thumb); [reviewUpload.images removeObject: self.reviewUploadImg]; [self.navigationController popViewControllerAnimated:TRUE]; }

  • Can I do this?? Trying to load an object from within itself.

    - by Smikey
    Hi all! I have an object which conforms to the NSCoding protocol. The object contains a method to save itself to memory, like so: - (void)saveToFile { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver encodeObject:self forKey:kDataKey]; [archiver finishEncoding]; [data writeToFile:[self dataFilePath] atomically:YES]; [archiver release]; [data release]; } This works just fine. But I would also like to initialise an empty version of this object and then call its own 'Load' method to load whatever data exists on file into its variables. So I've created the following: - (void)loadFromFile { NSString *filePath = [self dataFilePath]; if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSData *data = [[NSMutableData alloc] initWithContentsOfFile:[self dataFilePath]]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; self = [unarchiver decodeObjectForKey:kDataKey]; [unarchiver finishDecoding]; } } Now this second method doesn't manage to load any variables. Is this line not possible perhaps? self = [unarchiver decodeObjectForKey:kDataKey]; Ultimately I would like to use the code like this: One viewController takes user entered input, creates an object and saves it to memory using [anObject saveToFile]; And a second viewController creates an empty object, then initialises its values to those stored on file by calling: [emptyObject loadFromFile]; Any suggestions on how to make this work would be hugely appreciated. Thanks :) Michael

  • UIView as dictionary key?

    - by subw
    I want to have a NSDictionary that maps from UIViews to something else. However, since UIViews do not implement the NSCopying protocol, I can't use them directly as dictionary keys.

  • Interface Builder hang up on retina images

    - by Jim
    In my app I create 2 folders for images "Standard" and "Retina" where I put a lot of images for my app. When I open one of my xib file, Interface Builder hang up... I found that if I remove Retina Image that is used by this xib, then IB will open xib without any problem... This problem occurs only with 1 xib file, another xib files can be opened without any problems. What can be the reason of hang up? Can image be bad? Or maybe I shouldn't put Retina Images to "Retina" folder? What can be the reason? Thanks...

  • How to manage a single-selection (exclusive) list?

    - by Andy
    I've got a detail view that consists of a table view with a few rows of data. I can fill the rows just fine, and moving back and forth from the parent view to the subview works too. This detail view should allow the user to select a single value, placing a checkmark accessory in the cell and then returning to the parent view (where the selected value becomes the cell.textLabel.text property of the cell from which the detail view was called). This all works as of right now. However, when the user taps the cell in the parent view to go back to the detail view (to change their selection), my checkmark has disappeared and I cannot for the life of me figure out how to make it stay. Here's my cellForRowAtIndexPath: method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; } NSString *labelText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumberLabel"]; cell.textLabel.text = labelText; NSString *currentLabel = [ruleBuilder.tableView cellForRowAtIndexPath:selectedIndexPath].textLabel.text; if (labelText == currentLabel) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } NSString *detailText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumber"]; cell.detailTextLabel.text = detailText; return cell; } I've checked out Apple's sample code for exclusive-list management in Table View Programming Guide, but the snippet seems incomplete, and I can't find the related code in Apple's sample code. This doesn't seem like it ought to be that hard to do.

  • Programmatically remove the header of UITableView and automatically resizes the content to fill in the removed area.

    - by code007
    Hello all, I have added a UIButton in the header section of the UITableView via the interface builder and would like to remove the access to the button in certain cases. I have tried to use the '.hidden = TRUE' property but it just hides the button from the view, leaving a white space behind. How do I programmatically remove the header of UITableView and have the table's content automatically resizes to fill in the removed header area?

  • Poping multiple levels in UITableViewController

    - by LavaSlider
    I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed. I tried: [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; [self.navigationController popViewControllerAnimated: NO]; and [self.navigationController popViewControllerAnimated: NO]; [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

  • IBOutlet on properties and exposition of the class

    - by Espuz
    Apple, for memory management issues, recommend defining outlets on properties, not in the attribute declaration. But, as far as I know, declaring properties exposes the class to external classes, so this could be dangerous. On UIViewController we have the main view definition and the logic, so MVC is slightly cheated in this cases. What is the beteer approach, Apples's recommendation for memory-management or armored classes?

  • Why does UITableViewCell have a contentView property?

    - by mystify
    What's the point of this contentView property? I mean: Why aren't all the subviews just added to self? Let me get that right: Every cell is a view (UITabvleViewCell is a UIView subclass). And this fat view has another fat view with same bounds sitting on top of it, called contentView. That contentView then carries all those other subviews. Now why didn't they save that extra chunk of memory? Is there any genius logic behind this decision? Would love to understand the reason for this.

  • Rewarding iOS app beta testers with in app purchase?

    - by Partridge
    My iOS app is going to be free, but with additional functionality enabled via in app purchase. Currently beta testers are doing a great job finding bugs and I want to reward them for their hard work. I think the least I can do is give them a full version of the app so that they don't have to buy the functionality themselves. However, I'm not sure what the best way to do this is. There do not appear to be promo codes for in app purchase so I can't just email out promo codes. I have all the tester device UDIDs so when the app launches I could grab the device UDID and compare it to an internal list of 'approved' UDIDs. Is this what other developers do? My concerns: The in app purchase content would not be tied to their iTunes account, so if beta testers move to a new device they would not be able to enable the content unless I released a new build in the app store with their new UDID. So they may have to buy it eventually anyway. Having an internal list leaves a hole for hackers to modify the list and add themselves to it. What would you do?

  • xml parser not able to read all the nodes of the xml

    Hi i am trying to get values from all the nodes of a xml returned from a web service. But my code only reads first node, it does not read it further. code: -(void)parseData{ NuanceAppDelegate *appDel = (NuanceAppDelegate *)[[UIApplication sharedApplication] delegate]; NSString *url = @"http://cmweb.bpomatrix.net/SmartPhoneService.svc/login/"; url = [[[url stringByAppendingString:UserName] stringByAppendingString:@"/"] stringByAppendingString:Password]; url = [[url stringByAppendingString:@"/"] stringByAppendingString:appDel.CPAID]; NSLog(@"log: @%",url); NSURL *loginURL = [NSURL URLWithString:url]; NSXMLParser *home_Parser = [[NSXMLParser alloc] initWithContentsOfURL:loginURL]; [home_Parser setDelegate:self]; dict = [[NSMutableDictionary alloc] init]; [home_Parser parse]; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict{ if([elementName isEqualToString:@"Address"]) addressFound = TRUE; if([elementName isEqualToString:@"Name"]) nameFound = TRUE; if([elementName isEqualToString:@"LoyaltyNum"]) loyaltyNumFound = TRUE; if([elementName isEqualToString:@"City"]) cityFound = TRUE; if([elementName isEqualToString:@"Province"]) proFound = TRUE; if([elementName isEqualToString:@"Zip"]) zipFound = TRUE; //NSLog(@"Response %@",responseFound); } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ if(addressFound) { [dict setObject:string forKey:@"address"]; addressFound = FALSE; } else if(nameFound) { [dict setObject:string forKey:@"name"]; nameFound = FALSE; } else if(loyaltyNumFound) { [dict setObject:string forKey:@"loyaltyNum"]; loyaltyNumFound = FALSE; } else if(cityFound) { [dict setObject:string forKey:@"city"]; cityFound = FALSE; } else if(proFound) { [dict setObject:string forKey:@"province"]; proFound = FALSE; } else if(zipFound) { [dict setObject:string forKey:@"zip"]; zipFound = FALSE; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"clsUserProfile"]) { [self parsingOver]; } } -(void)parsingOver { NuanceAppDelegate *appDel = (NuanceAppDelegate *)[[UIApplication sharedApplication] delegate]; appDel.dictProfile = dict; }

  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • How should I properly format this code?

    - by ct2k7
    Hi, I've a small issue here. I am using an if statement with UIAlertView and I have two situations, both result in UIAlertViews. However, in one situation, I want to dismiss just the UIAlertView, the other, I want the UIAlertView to be dismissed and view to return to root view. This code describes is: if([serverOutput isEqualToString:@"login.true"]){ [Alert dismissWithClickedButtonIndex:0 animated:YES]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; UIAlertView *success = [[UIAlertView alloc] initWithTitle:@"Success" message:@"The transaction was a success!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [success show]; [success release]; } else { UIAlertView *failure = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"The transaction failed. Contact sales operator!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [failure show]; [failure release]; } } -(void)alertView: (UIAlertView *)success clickedButtonAtIndex: (NSInteger)buttonIndex{ switch(buttonIndex) { case 0: { [self.navigationController popToRootViewControllerAnimated:YES]; } } } So, in both cases, they follow the above action, but obviously, that's not what I want. Any ideas on what I do here?

  • GameKit server disconnect makes session invalid

    - by Markus
    Hi everyone, I'm trying to build a 4 player multiplayer game using GameKit. I tried many things and I'm currently using client/server mode, meaning that I have 1 session in GKSessionModeServer and 3 other sessions connecting to this one in GKSessionModeClient. My goal is, that when a user leaves the game or gets disconnected for whatever reason, that the others can continue their game. So far this works if any of the Clients leave the game, but if the Sevrer leaves the game, send and receive calls are not reaching the other peers anymore. I tried the same with 4 peers in GKSessionModePeer with the same result (where the player who accepts connections cannot quit). Does anyone had better success in making this work? Any help is highly appreciated. Thanks!

  • Oracle access from iOS

    - by Michael Lowman
    I'm developing an iPad app that needs read-only access to an Oracle database. Is there any way to do this? As far as I can see, the only options are using OCI, which requires a prebuilt binary in the form of the instant client (and not built for ARM), or OJDBC drivers. Both of these seem to be out of the question. In my research I have discovered that libmysqlclient compiles for arm with minimal tuning. This is a stretch, but is there any possible way to use this to my advantage? I have seen this product providing odbc connectivity through the use of a Windows gateway machine using the ODBC client libraries, but this solution really isn't an option for me at the present time. Any ideas?

  • reloading table

    - by edie
    Hi... I've have a table view that consist of item list that depends on the item that were purchased using in app purchasing. My question was how can I reload the tableView when the purchasing was completed/(or when new item was added on my list). The response of the storekit takes time to complete. Are there anyways to tell the app that the purchasing was completed and new item was added on my list so that I can reload my tableView. At this time I reloading my table view by adding [myTableView reloadData] in viewWillAppear method. But what if the user was already viewing the tableView, I can't reload the tableView because the viewWillAppear had passed. thanks...
