• How to use LIKE query in sqlite & iPhone

  - by 4thSpace

  I'm using the following for a LIKE query. Is this technique for LIKE correct? selectstmtSearch = nil; if(selectstmtSearch == nil){ const char *sql = "SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname like ?001 order by t1.cityname"; if(sqlite3_prepare_v2(databaseSearch, sql, -1, &selectstmtSearch, NULL) == SQLITE_OK) { sqlite3_bind_text(selectstmtSearch, 1, [[NSString stringWithFormat:@"%%%@%%", searchText] UTF8String], -1, SQLITE_TRANSIENT); } } The problem I'm having is after a few uses of this, I get an error 14 on sqlite3_open(), which is unable to open database. If I replace the LIKE with something such as: SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname = ? order by t1.cityname It works fine. I do open/close the DB before after the above code. Is there a way to troubleshoot exactly why the database can't be opened and what its relationship to my LIKE syntax is?

• Application creashing in saveAction of Coredata iphone sdk

  - by neha

  Hi all, In my application I'm inserting data using Coredata like this: GoodWork * newGoodwork = (GoodWork *)[NSEntityDescription insertNewObjectForEntityForName:@"GoodWork" inManagedObjectContext:self.managedObjectContext]; // Step 2: Set Properties [newGoodwork setEletitle:[NSString stringWithFormat:@"%@", aGoodwork.eletitle]]; [newGoodwork setEletxt:[NSString stringWithFormat:@"%@", aGoodwork.eletxt]]; [newGoodwork setSortId:[NSNumber numberWithInt:sortId]]; // Step 3: Save Object [self saveAction]; Everythinng is working fine but in saveAction which is: - (void)saveAction { NSError *error; if (![self.managedObjectContext save:&error]) { NSLog(@"Unresolved Core Data Save error %@, %@", error, [error userInfo]); exit(-1); } } My application is crashing after processing if condition. I'm not inserting all the fields in the entity "Goodwork". Can that be the reason? Thanx in advance.

• NSFetchedResultsController - Delegate methods crashing under iPhone OS 3.0, but NOT UNDER 3.1

  - by Scott Langendyk

  Hey guys, so I've got my NSFetchedResultsController working fine under the 3.1 SDK, however I start getting some weird errors, specifically in the delegate methods when I try it under 3.0. I've determined that this is related to the NSFetchedResultsControllerDelegate methods. This is what I have set up. The inEditingMode stuff has to do with the way I've implemented adding another static section to the table. - (void)controllerWillChangeContent:(NSFetchedResultsController*)controller { [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type{ NSIndexSet *sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex]; if(self.inEditingMode){ sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex + 1]; } switch (type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath{ NSIndexPath *relativeIndexPath = indexPath; NSIndexPath *relativeNewIndexPath = newIndexPath; if(self.inEditingMode){ relativeIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section + 1]; relativeNewIndexPath = [NSIndexPath indexPathForRow:newIndexPath.row inSection:newIndexPath.section + 1]; } switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:relativeNewIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:relativeIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } -(void)controllerDidChangeContent:(NSFetchedResultsController *)controller{ [self.tableView endUpdates]; } When I add an entity to the managed object context, I get the following error: Serious application error. Exception was caught during Core Data change processing: *** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1) with userInfo (null) I put a breakpoint on objc_exception_throw, and the crash seems to be occuring inside of controllerDidChangeContent. If I comment out all of the self.tableView methods, and put a single [self.tableView reloadData] inside of controllerDidChangeContent, everything works as expected. Anybody have any idea as to why this is happening?

• Downloading file with ASIHTTPRequest - iPhone app

  - by lostInTransit

  Hi I am using the ASIHTTPRequest source code to download a file from a remote location. Surprisingly, the download happens but nothing happens after that. I have put in a log statement in the handleBytesAvailable method and can see the entire file worth of data is downloaded in parts and added to the fileDownloadOutputStream variable. But once all the bytes have been downloaded, nothing happens. The delegate methods are not called (neither fail, nor success). Can someone please tell me what is happening? Or what is the correct way to download a file from a remote server using ASIHTTPRequest? Thanks.

• iPhone Table View Cell Image: Working on simulator, not showing on real device

  - by Graeme

  Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. At first 3 did, but then I "cleaned headers" and now none appear. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }

  Does anyone have a snippet that uses the AudioToolBox framework that can be used to play a short sound? I would be grateful if you shared it with me and the rest of the community. Everywhere else I have looked doesn't seem to be too clear with their code. Thanks!

• Drawing CGPathRef in ScrollView using Iphone sdk.

  - by Ann

  Hi all. I want to draw some curve in my scroll view using CGPathRef. I tried to draw this path but i see only the part of my CGPathRef which located at 320x480 pixels. Is it way to do that. Thank you in advance. Here is my code path = CGPathCreateMutable(); CGContextBeginPath(ctx); CGContextMoveToPoint(ctx, [[pathArray objectAtIndex:0]CGPointValue].x,[[pathArray objectAtIndex:0]CGPointValue].y ); for(int i = 1; i < [pathArray count]; ++i) { CGContextAddLineToPoint(ctx, [[pathArray objectAtIndex:i]CGPointValue].x, [[pathArray objectAtIndex:i]CGPointValue].y); } CGContextClosePath(ctx); CGContextSetRGBFillColor(ctx, 0.5, 0.3, 0.2, 0.5); CGContextFillPath(ctx); And when I scroll my view the line does not change its location. My goal is to move this line during scrolling.

• iPhone: Utility Application - Open Flipside on startup

  - by Joel

  I have an application that I started with the Utility Application template. I'm using the Flipside for the Settings screen. I'm having the settings serialized to a file when the app is closed and deserialized when the app is opened. If there is no file to deserialize at startup, I want the flipside to be shown so the user can enter required information. This is what I have: - (void)viewDidLoad { flipController = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; flipController.delegate = self; flipController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; if(![self deserialize]) { [self showInfo]; } } - (IBAction)showInfo { [self presentModalViewController:flipController animated:YES]; } showInfo is the method that is called with the little 'i' button is pressed on the MainView. The button works, however my call in viewDidLoad doesn't. I have run through my code with the debugger. [self deserialize] is returning NO and [self showInfo] is being called, and I checked if flipController is nil in that context, and it's not. I've searched around and couldn't find anyone who's tried to do the same thing. I'm stumped to as why this isn't working. Anyone see what I'm doing wrong? Thanks

• Taking video from video camera and displaying it with MPMoviePlayerController IPhone SDK

  - by Daniel

  Has anyone tried taking a video from the camera and then using the video player provided to play it? When you take the video in portrait mode, sometimes the movie will play (when the player puts it in landscape mode) and when it puts it in portrait mode you cannot view the movie all you hear is sound,sometimes in landscape mode is flickers and does not play right, has anyone encountered this and found a way to fix it? My code to play the video looks like this: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *urls=[info objectForKey:@"UIImagePickerControllerMediaURL"] ; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[info urls]]; if (moviePlayer) { [moviePlayer play]; } } I checked settings on the docs nothing seems like it would fix this...Thanks

• Avoid hardcoding iPhone screen size with programmatic view creation

  - by miorel

  Hi, I was looking up how to create a view programmatically and found the following example code: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; This works great, except I don't like that it hardcodes the size of the screen. Is there a way to look up the size of the screen? An important point someone brought up is that if the app is running during a phone call then the screen will be slightly smaller because of the green "return to call" bar.

• how to make a explorer like logic in Obj C for iphone

  - by Ekra

  Hi friends, To make the query simple first we can take example:- If we open the explorer in our Windows desktop how it shows us the tree. As we keep on clicking the tree it get expanded and shows the file in it. The same way I want to show a explorer which gets expanded as the user clicks on it(I want to get the business logic the UI is simple). The information of the explorer i.e. which folder has what files come in a XML format to me. I have 2 options of getting the XML either I can get the whole XML at one query(but I guess this might slow the application if the XML is quite big). OR I can get the XML for every list like first only the root structure then if user clicks on any folder in root I can get the list(the files or folders inside that folder) of that particular folder. Now the question is What would be the approach to implement both the method and which would be the best. Should I need to create some dictionary to maintain the link of the files like which file is inside what. I am not able to get as how I would be able to link all the files. Any hint or direction would be highly appreciated. Thanks in advance

• iphone: view index

  - by Mike

  I have a view between other views, the order may vary. For example: viewA on top of viewB, on top of viewC, or in another order. Suppose I have viewA, viewB, viewC, viewD and viewE A is on the top and E on the bottom. I need to replace viewC with viewZ, but I need to insert viewZ in the same index of viewC. How do I know, before removing viewC, what index it has, so I can insert viewZ using [self.view insertSubview:viewZ atIndex:?????) and it will be at the same level? thanks for any help.

• How is the iPhone SMS compose view implemented?

  - by erotsppa

  Regarding the SMS compose view as show in the picture below: I have two questions: 1) How is the text entry box implemented? There are no standard control from the API and the box is smart enough to resize when you press enter OR when the text is too long. Also the bar resizes with it. How is this done with the least coding? 2) How to code it such that when the keyboard shows up the whole view shifts up? Typically when the keyboard shows, it goes over your current view.

• iPhone: Get indexPath of Predicate Object

  - by Nic Hubbard

  I am using a predicate to find an object in core data. I can successfully find the object that I want, but I need to also get the indexPath of that object, so that I can push a details view in for that object. Currently I have the following code for getting my object: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity:[NSEntityDescription entityForName:@"Ride" inManagedObjectContext:self.managedObjectContext]]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"title = %@ AND addressFull = %@", view.annotation.title, view.annotation.subtitle]; [fetchRequest setPredicate:predicate]; NSMutableArray *sortDescriptors = [NSMutableArray array]; [sortDescriptors addObject:[[[NSSortDescriptor alloc] initWithKey:@"title" ascending:YES] autorelease]]; [sortDescriptors addObject:[[[NSSortDescriptor alloc] initWithKey:@"addressFull" ascending:YES] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setReturnsObjectsAsFaults:NO]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObjects:@"title", @"addressFull", nil]]; NSError *error = nil; NSArray *fetchedItems = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; // Sohow what record we returned NSLog(@"%@",[fetchedItems objectAtIndex:0]); So, I can correctly get my object into an array. But how do I translate that object into an indexPath?

• Detecting iPhone camera orientation

  - by Stephen Petschulat

  I'm getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll. In the UIImagePickerControllerDelegate callback method, the UIImage.imageOrientation comes up as UIImageOrientationRight no matter how the photo is taken. When reading it off the Camera Roll, a landscape shot (turned left) comes up UIImageOrientationUp while a portrait shot comes up UIImageOrientationRight. How can I reliably get the camera orientation in both situations?

• Using sectioned tables from an sqlite file with an iPhone uitableview

  - by Chris

  I am currently trying to make a sectioned table like this: Section 1: Entry 1 Entry 2 Entry 3 Section 2: Entry 4 Entry 5 Entry 6 Section 3: Entry 7 Entry 8 ... However, using this code: Event *lists = (Event *)[eventList objectAtIndex:indexPath.row]; accessStatement = "select * from DatabaseName"; [self findEvents]; // Code that builds each object's strings from database cell.textLabel.text = lists.name; Section 1: Entry 1 Entry 2 Entry 3 Section 2: Entry 1 Entry 2 Entry 3 Section 3: Entry 1 Entry 2 ... It keeps on repeating itself. How do I make the index so that it continues in each section rather than restarts? Thanks in advance.
