  • insertNewObjectForEntityForName:inManagedObjectContext: returning NSNumber bug?

    - by beinstein
    I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set one specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 I've tried everything from clean all targets, to restarting both mac and iPhone, even editing the model so that the relationship in question is to-one instead of to-many. No matter what I do, the same problem appears. Has anyone ever seen anything like this before?

  • objc[989] objc_exception_throw failed.

    - by thyrgle
    I was just adding some more CCSprites to a CCLayer and it just starts crashing giving me the error: objc[989] objc_exception_throw failed. Is there like a limit to the amount of CCSprites you can have on a screen or something? I added the CCSprites doing the following with the CCSprites already declared at interface: L1Circle1 = [CCSprite spriteWithFile:@"LaserCircle.png"]; [L1Circle1 setPosition:ccp(180,180)]; [self addChild:L1Circle1]; What am I doing wrong?

  • How do I send text to a UITextView?

    - by Lee
    I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

  • UIViewController prevent view from unloading

    - by Ican Zilb
    When my iPhone app receives a Memory warning the views of UIViewControllers that are not currently visible get unloaded. In one particular controller unloading the view and the outlets is rather fatal. I'm looking for a way to prevent this view from being unloaded. I find this behavior rather stupid - I have a cache mechanism, so when a memory warning comes - I unload myself tons of data and I free enough memory, but I definitely need this view untouched. I see UIViewController has a method 'unloadViewIfReloadable', which gets called when the Memory Warning comes. Does anybody know how to tell Cocoa Touch that my view is not reloadable? Any other suggestions how to prevent my view from being unloaded on Memory Warning? Thanks in advance

  • Get CALayers view

    - by eaigner
    Hi, is it somehow possible to get the nearest "container" NSView of a CALayer? My problem is I'm managing tracking areas in my "container" NSView, and those need to be updated if a layer is moved/added etc. and i would like to automate that somehow instead of calling my -updateTrackingAreas function manually. Regards, Erik

  • UIDisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by UIDisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • Subclass not seeing superclass' instance variable

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? If I make this ivar a property then I can access it by self.x. What's worse is sometimes the error disappears, so something in my code is obviously causing this error but I cannot figure it out.

  • UITableViewCell imageView images loading small even when they are the correct size!

    - by Alex Barlow
    Im having an issue whilst loading images into a UITableViewCell after an asynchronous download and placement into an UIImage variable.. The images appear smaller than they actually are! But when scrolled down and scrolled back up to the image, or the whole table is reloaded, they appear at the correct size... Here is a code excerpt... - (void)reviewImageDidLoad:(NSIndexPath *)indexPath { ThumbDownloader *thumbDownloader = [imageDownloadsInProgress objectForKey:indexPath]; if (thumbDownloader != nil) { UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:thumbDownloader.indexPathInTableView]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 0.0; [UIView commitAnimations]; cell.imageView.image = thumbDownloader.review.thumb; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.4]; [self.tableView cellForRowAtIndexPath:indexPath].imageView.alpha = 1.0; [UIView commitAnimations]; } } Here is an image of the app just after calling this method.. http://www.flickr.com/photos/arbarlow/5288563627/ After calling tableView reloadData or scrolling around the appear correctly, go the the next flickr image, to see the normal result, but im sure you can guess that.. Does anyone have an ideas as to make the images appear correctly? im absolutely stumped?! Regards, Alex iPhone noob

  • steps to fix a project that won't compile

    - by eco_bach
    Hi Pulling my hair out in trying to get a simple window based project to compile. I am running both 3.2.2 and 3.2.3 versions of Xcode. The latter is set up in a separate folder. Originally I used the latter to create and compile my project against the new 4.0 sdk. It compiled fine. Then I made the mistake of deleting some sdks I thought I no longer needed. Ever since I can no longer compile. Right now I get a dozen or so errors similar to the following "_OBJC_CLASS_$_CATransition", referenced from: objc-class-ref-to-CATransition in ViewTransitionsAppDelegate.o My active executable is the iphone simulator 4 and Base SDK is iPhone device 3.0. I tried reinstalling the xcode3.2.3 installer, no difference. I'm totally stymied, as my project WAS working and compiling fine, both to the simulator and external device. Are there any best practices or recommended steps in fixing or rebuilding a project when it won't compile? Any help welcome!

  • Issues dismissing keyboard conditionally with on iPhone

    - by Chris
    I have an app that has a username and password field. I want to validate the input before the the user is allowed to stop editing the field. To do that, I'm using the textFieldShouldEndEditing delegate method. If the input doesn't validate I display a UIAlertView. This approach works as advertised - the user cannot leave the field if the input doesn't validate. To have the done button on the keyboard dismiss the keyboard, I call resignFirstResponder on the textfield. The issue I have is the alert is being called twice. How do I keep the alert from showing twice?

  • How can I add settings in the settings application for the iPhone

    - by Eytan
    I have my user preferences set to display in the system-settings application BUT I want to give them the option of adding additional settings. Specifically, the user has a group 'favorites' in the settings bundle and they then can put in the details of their three favorite contacts. However, I want to give the user the option of adding more. I know how to do this with inapp but can this be done through the settings application?

  • What's an easy way to set up object communication in Obj-C?

    - by seaworthy
    I am trying to send a slider value from a controller object to a method of a model object. The later is implemented in the separate file and I have appropriate headers. I think the problem is that I am not sure how to instantiate the receiver in order to produce a working method for the controller. Here is the controller's method. -(IBAction)setValue:(id)slider {[Model setValue:[slider floatValue]];} @implementation Model -(void)setValue:(float)n{ printf("%f",n); } @end What I get is 'Model' may not respond to '+setValue' warning and no output in my console. Any insight is appreciated.

  • Iphone sdk - please help , 1 view takes me 45 minutes to do :(

    - by Dave
    Hey, I've been working on a Cook Book App but each view ( or recipie page) takes about 45 minutes to complete so as you can imagine its taking forever. The problem is that I have to manually: Set up a gradient image for the back ground (Somtimes I have to add a few image backgrounds to fit the view as I often use a scroll view, not sure how this could be automated?) Put an image behind the titles "Recipe name" , "Time needed" and an image to go behind the recipie instructions ( again I might need a few of these depending on how long the description is. Creating view controllers for main sections such as "Breakfast" and "Lunch" and then I need to manually create view controllers to go in these sections. Theres got to be a way to set up a template for this? Thanks for reading all of this.

  • Cocoa - NSFileManager removeItemAtPath Not Working

    - by Kevin
    Hey there everyone, I am trying to delete a file, but somehow nsfilemanager will not allow me to do so. I do use the file in one line of code, but once that action has been ran, I want the file deleted. I have logged the error code and message and I get error code: 4 and the message: "text.txt" could not be removed Is there a way to fix this error "cleanly" (without any hacks) so that apple will accept this app onto their Mac App Store? EDIT: This is what I am using: [[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL]; Thanks, kevin

  • Equivalent Carbon 32-bit call for using in 64-bit application - GetApplicationEventTarget().

    - by Dheeraj
    Hi All, I'm writing a 64-bit Cocoa application. I need to register for global key events. So I wrote this piece of code : - (void)awakeFromNib { EventHotKeyRef gMyHotKeyRef; EventHotKeyID gMyHotKeyID; EventTypeSpec eventType; eventType.eventClass=kEventClassKeyboard; eventType.eventKind=kEventHotKeyPressed; eventType.eventClass=kEventClassKeyboard; eventType.eventKind=kEventHotKeyPressed; InstallApplicationEventHandler(&MyHotKeyHandler,1,&eventType,NULL,NULL); gMyHotKeyID.signature='htk1'; gMyHotKeyID.id=1; RegisterEventHotKey(49, cmdKey+optionKey, gMyHotKeyID, **GetApplicationEventTarget**(), 0, &gMyHotKeyRef); } But since GetApplicationEventTarget() is not supported for 64-bit applications I'm getting errors. If I declare it, then I don't get any errors but the application crashes. Is there any equivalent method for GetApplicationEventTarget() (defined in Carbon framework) to use in 64-bit applications. Or is there any way to get the global key events using cocoa calls? Any help is appreciated. Thanks, Dheeraj.

  • Is NSDictionary key order guaranteed the same as initialized if it never changes?

    - by Thaurin
    I've run into the same problem as found in this question. However, I have a follow-up question. I seem to be in the same situation as the original asker: I have a plist with a hierarchy of dictionaries that define a configuration screen. These are not mutable and will stay the same throughout the application. Since the original discussion seems to focus on problems arising from mutating the dictionary, I must ask for comfirmation: is the order of a dictionary guaranteed the same as they are in the plist, i.e. as it is read (with initWithContentsOfFile)? Can I use allKeys on it in this case to get a correct-order array of keys if the dictionary never changes?
