  • iPhone: Save boolean into Core Data

    - by Nic Hubbard
    I have set up one of my core data attributes as a Boolean. Now, I need to set it, but XCode keeps telling me that it may not respond to setUseGPS. [ride setUseGPS: useGPS.on]; What is the method for setting a boolean in core data? All my other attributes are set this way, and they work great. So, not sure why a boolean does not work to be set this way?

  • iPhone UIControl and Subview

    - by Jack Thompson
    I currently have a UIControl, which has a number of subviews (image, label). Unfortunately when I use addTarget etc. It doesn't detect touches on the subviews. [myCustomView addTarget:self action:@selector(touchedView:) forControlEvents:UIControlEventTouchUpInside]; Is it possible for the UIControl to detect touches on subviews or should i be approaching it differently.

  • iPhone: Issue disabling Auto-Cap/autocorrect on a UITextField

    - by phil swenson
    For some reason, even though I disable the auto-cap and auto-correct of my UITextField, it's still capitalizing the first letter of my input. Here is the code: UITextField* textField = [[[UITextField alloc] initWithFrame:CGRectMake(90.0, 10.0, 213.0, 25.0)] autorelease]; [textField setClearButtonMode:UITextFieldViewModeWhileEditing]; textField.returnKeyType = UIReturnKeyGo; textField.autocorrectionType = FALSE; textField.autocapitalizationType = UITextAutocapitalizationTypeNone; textField.delegate = self; if (inputFieldType == Email) { label.text = @"Email:"; textField.keyboardType = UIKeyboardTypeEmailAddress; emailTextField = textField; textField.placeholder = @"Email Address"; } else { // password textField.secureTextEntry = TRUE; label.text = @"Password:"; if (inputFieldType == Password){ textField.placeholder = @"Password"; passwordTextField = textField; } if (inputFieldType == ConfirmPassword){ textField.placeholder = @"Confirm Password"; confirmPasswordTextField = textField; } } See screenshot:

  • How do I change my iPhone App binary filename

    - by Kamchatka
    I get the following error when I try to upload the application on iTunes Connect: "Binary file names cannot contain a space. Please rename your binary file and try again." If I try to Validate the Application in XCode, I get: "My Application.ipa: filename may not contain whitespace" So I guess I have to find a way to rename this .ipa file. I don't want to change my product name which has to stay "My Application". How can I do that? Thanks!

  • Return Selected Phone Address from iPhone Address Book

    - by Ali
    Hey, I found a tutorial online that extends that Apple QuickStart Application which is the basic Address Book Application and another that returns the first phone number regardless of what phone number was clicked. I want to display only the selected phone number in the label. The label is called phoneNumber: - (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{ ABMutableMultiValueRef phoneMulti = ABRecordCopyValue(person, kABPersonPhoneProperty); NSMutableArray *phones = [[NSMutableArray alloc] init]; int i; for (i = 0; i < ABMultiValueGetCount(phoneMulti); i++) { NSString *aPhone = [(NSString*)ABMultiValueCopyValueAtIndex(phoneMulti, i)autorelease]; [phones addObject:aPhone]; } NSString *mobileNo = [phones objectAtIndex:0]; self.phoneNumber.text = phones; [self dismissModalViewControllerAnimated:YES]; return NO; } How do I ensure that the label is the one selected by the user and not just the first array entry(or any other array entry i code in) Thanks

  • iPhone Foundation - performance implications of mutable and xxxWithCapacity:0

    - by Adam Eberbach
    All of the collection classes have two versions - mutable and immutable, such as NSArray and NSMutableArray. Is the distinction merely to promote careful programming by providing a const collection or is there some performance hit when using a mutable object as opposed to immutable? Similarly each of the collection classes has a method xxxxWithCapacity, like [NSMutableArray arrayWithCapacity:0]. I often use zero as the argument because it seems a better choice than guessing wrongly how many objects might be added. Is there some performance advantage to creating a collection with capacity for enough objects in advance? If not why isn't the function something like + (id)emptyArray?

  • Why does this JSON fail only in iPhone?

    - by 4thSpace
    I'm using the JSON framework from http://code.google.com/p/json-framework. The JSON below fails with this error: -JSONValue failed. Error trace is: ( Error Domain=org.brautaset.JSON.ErrorDomain Code=5 UserInfo=0x124a20 "Unescaped control character '0xd'", Error Domain=org.brautaset.JSON.ErrorDomain Code=3 UserInfo=0x11bc20 "Object value expected for key: Phone", Error Domain=org.brautaset.JSON.ErrorDomain Code=3 UserInfo=0x1ac6e0 "Expected value while parsing array" ) JSON being parsed: [{"id" :"2422","name" :"BusinessA","address" :"7100 U.S. 50","lat" :"38.342945","lng" :"-90.390701","CityId" :"11","StateId" :"38","CategoryId" :"1","Phone" :"(200) 200-2000","zip" :"00010"}] I think 0xd represents a carriage. When I put the above JSON in TextWrangler, I don't see any carriage returns. I got the JSON by doing "po myjson" in the debugger. It passes this validator: http://json.parser.online.fr/. Can anyone see what the problem may be?

  • [iPhone] Objective-C : UIScrollView manual paging

    - by Daniel
    Hi Folks! I want to use the scrollview as something like a picker in horizontal mode. The scrollview holds up to seven subviews. Each subview represents a value. Always three views are visible and the one in the middle is the selected one. Scrollview visible at start: __ | V1 | V2 Scrollview set to view/value two: V1 | V2 | V3 Scrollview set to last value: V2 | V3 | __ The real problem I have got is the "pagingEnabled" flag. If pagingEnabled is set to YES the scrollview pages always three subviews/values instead of only one. If pagingEnabled is set to NO the scrollview does not clinch. Is there a nice solution for my problem? Thanks a lot, Dan ;)

  • iPhone - return from an NSOperation

    - by lostInTransit
    Hi I am using a subclass of NSOperation to do some background processes. I want the operation to be cancelled when the user clicks a button. Here's what my NSOperation subclass looks like - (id)init{ self = [super init]; if(self){ //initialization code goes here _isFinished = NO; _isExecuting = NO; } return self; } - (void)start { if (![NSThread isMainThread]) { [self performSelectorOnMainThread:@selector(start) withObject:nil waitUntilDone:NO]; return; } [self willChangeValueForKey:@"isExecuting"]; _isExecuting = YES; [self didChangeValueForKey:@"isExecuting"]; //operation goes here } - (void)finish{ //releasing objects here [self willChangeValueForKey:@"isExecuting"]; [self willChangeValueForKey:@"isFinished"]; _isExecuting = NO; _isFinished = YES; [self didChangeValueForKey:@"isExecuting"]; [self didChangeValueForKey:@"isFinished"]; } - (void)cancel{ [self willChangeValueForKey:@"isCancelled"]; [self didChangeValueForKey:@"isCancelled"]; [self finish]; } And this is how I am adding objects of this class to a queue and listening for KVO notifications operationQueue = [[NSOperationQueue alloc] init]; [operationQueue setMaxConcurrentOperationCount:5]; [operationQueue addObserver:self forKeyPath:@"operations" options:0 context:&OperationsChangedContext]; - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if (context == &OperationsChangedContext) { NSLog(@"Queue size: %u", [[operationQueue operations] count]); } else { [super observeValueForKeyPath:keyPath ofObject:object change:change context:context]; } } To cancel an operation (on a button click for instance), I tried calling -cancel but it doesn't make a difference. Also tried calling -finish but even that doesn't change anything. Every time I add an operation to the queue, the queue size only increases. finish is called (checked using NSLog statements) but it doesn't really end the operation. I'm still not very confident I'm doing this right Can someone please tell me where I am going wrong? Thanks a lot

  • iPhone Core Data: request for member 'tableView' in something not a structure or union

    - by Nic Hubbard
    I am trying to use CoreData to populate a UITableView. I have been using the developer "Locations" project, and I think I have everything correct. But, now I am getting the following error when I build: request for member 'tableView' in something not a structure or union Why would it be confused about tableView? I am using it many times in the methods. The errors seem to be coming from: [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES]; Ideas?

  • 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?

  • 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)]; }
