  • NSNumber floatValue not equal to NSNumber value

    - by Mirkules
    Hi Everyone, First post here. Having a problem with NSNumber's floatValue method -- somehow, it returns an imprecise number. Here's the problem: I store a bunch of NSNumbers in an array, like this: NSArray *a = [NSArray arrayWithObjects: [NSNumber numberWithFloat:0.04f], [NSNumber numberWithFloat:0.028f], [NSNumber numberWithFloat:0.016f], [NSNumber numberWithFloat:0.004f], nil]; Then I try to retrieve the first value (for example): NSNumber n = (NSNumber) [a objectAtIndex:0]; CGFloat f = [n floatValue]; In the debugger, n shows a value of 0.04 (in the summary column), but f shows a value of 0.0399999991. What am I doing wrong here? Thanks everyone.

  • Change NSNumber value by allocating new NSNumber?

    - by Peter Hajas
    I understand that NSNumber is immutable, but I still have the need to change it in my app. I use it because it's an object, and therefore usable with @property (if I could, I would use float or CGFloat in a heartbeat, but sadly, I can't). Is there any way to just overwrite the old NSNumber instance? I'm trying this: NSNumber *zero = [[NSNumber alloc] initWithFloat:0.0]; myNSNumber = zero but this doesn't change the value. This is a simplified version of my code, as I'm changing the root view controller's parameter (I know, not MVC-friendly). Still, the changing of the value should be the same assignment, right? Should I release myNSNumber first? What should I set the @property at for myNSNumber? Thanks!

  • get type of NSNumber

    - by okami
    I want to get the type of NSNumber instance. I found out on http://www.cocoadev.com/index.pl?NSNumber this: NSNumber *myNum = [[NSNumber alloc] initWithBool:TRUE]; if ([[myNum className] isEqualToString:@"NSCFNumber"]) { // process NSNumber as integer } else if ([[myNum className] isEqualToString:@"NSCFBoolean"]) { // process NSNumber as boolean } Ok, but this doesn't work, the [myNum className] isn't recognized by the compiler. I'm compiling for iPhone.

  • Optimizing NSNumber numberWithInt:

    - by Riviera
    I am profiling an iPhone app and I noticed a strange pattern. In a certain block of code that's called quite frequently... [item setQuadrant:[NSNumber numberWithInt:a]]; [item setIndex:[NSNumber numberWithInt:b]]; [item setTimestamp:[NSNumber numberWithInt:c]]; [item setState:[NSNumber numberWithInt:d]]; [item setCompletionPercentage:[NSNumber numberWithInt:e]]; [item setId_:[NSNumber numberWithInt:f]]; ...the first call to [NSNumber numberWithInt:] takes an inordinate amount of time, in the order of 10-15x that of the remaining calls. I've verified that the results are consistent if I shuffle the lines (the first line is always the slow one, by the same ratio). Is there something going on that I'm not aware of? Perhaps this happens because this block is inside a try/catch?

  • Can I use an NSDecimalNumber anywhere that an NSNumber is expected?

    - by Nick Forge
    NSDecimalNumber is a subclass of NSNumber, and from what I can tell, it implements all of the NSNumber methods as expected for an NSNumber instance. Given that, is it ok to give NSDecimalNumbers to any code that is expecting an NSNumber? The only possible issue might be code that checks that an argument is an instance of NSNumber, but since NSNumber is a class-cluster, code like this would have to check that the instance is a subclass of NSNumber, and NSDecimalNumber instances should pass the same tests.

  • Restkit Serializing a Boolean from NSNumber

    - by angelokh
    One of managed objects has one attribute 'isMember' represented by NSNumber type. When serialize to Json post body by RestKit, it always give 0/1 instead of YES/NO or true/false. When mapping from json result to objects, RestKit is able to successfully turn YES/NO to NSNumber. What is the way to force serialize the boolean attribute to YES/NO or true/false? Serialize: 0 -> 0, 1 -> 1 Deserialize : YES/true -> 1, NO/false -> 0

  • Unable to store NSNumber in core data

    - by Kamlesh
    Hi all, I am using Core Data in my application.I have an attribute named PINCode which has property Int64. Now,in my app I take the PIN code from a text field,convert it into NSNumber and try to store as an attribute value for an entity.But I am unable to do so.The exception that it shows on the console is:- Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unacceptable type of value for attribute: property = "PINCode"; desired type = NSNumber; given type = NSCFString; value = 121.' Here is the code:- (Conversion to NSNumber):- NSString *str= txtPINCode.text; NSNumber *num = [[NSNumber alloc]init]; int tempNum = [str intValue]; num = [NSNumber numberWithInt:tempNum]; (Storing in core data entity):- NSManagedObjectContext *context = [appDelegate managedObjectContext]; NSManagedObject *newContact; newContact = [NSEntityDescription insertNewObjectForEntityForName:@"MemberTable" inManagedObjectContext:context]; [newContact setValue:num forKey:@"PINCode"]; The app crashes at this point.I am unable to find the reason of crash.I have also tried to check the conversion by the following code:- NSNumber *testNumber = [[NSNumber alloc]init]; id test = num; BOOL testMe = [test isKindOfClass:(Class)testNumber]; Can anybody help me with this?? Thanks in advance.

  • NSNumber >= 13 won't retain. Everything else will.

    - by jkap
    The code I'm currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS. I turned on NSZombieEnabled and am now getting *** -[CFNumber retain]: message sent to deallocated instance 0x3c78420. Here's the call stack: #0 0x01eac3a7 in ___forwarding___ #1 0x01e886c2 in __forwarding_prep_0___ #2 0x01e3f988 in CFRetain #3 0x01e4b586 in _CFArrayReplaceValues #4 0x0002a2f9 in -[NSCFArray insertObject:atIndex:] #5 0x0002a274 in -[NSCFArray addObject:] #6 0x00010a3b in -[Faves addObject:] at Faves.m:24 #7 0x000062ff in -[ShowController processFave] at ShowController.m:458 #8 0x002af405 in -[UIApplication sendAction:to:from:forEvent:] #9 0x00312b4e in -[UIControl sendAction:to:forEvent:] #10 0x00314d6f in -[UIControl(Internal) _sendActionsForEvents:withEvent:] #11 0x00313abb in -[UIControl touchesEnded:withEvent:] #12 0x002c8ddf in -[UIWindow _sendTouchesForEvent:] #13 0x002b27c8 in -[UIApplication sendEvent:] #14 0x002b9061 in _UIApplicationHandleEvent #15 0x02566d59 in PurpleEventCallback #16 0x01e83b80 in CFRunLoopRunSpecific #17 0x01e82c48 in CFRunLoopRunInMode #18 0x02565615 in GSEventRunModal #19 0x025656da in GSEventRun #20 0x002b9faf in UIApplicationMain #21 0x00002498 in main at main.m:14 If it wasn't isolated to NSNumbers of a certain range, I'd assume I screwed something up with my memory management, but I've just got no idea.

  • iPhone NSXMLParser parsing string and storing in a NSNumber variable and different data types

    - by anubhav
    Hi, I am trying to parse a XML File using NSXMLParser, I also have a Container class, in which I have a few instance variables. One of the elements that I am trying to parse in the XML is: <book sn="32.859669048339128" pn="-116.917800670489670"> I am trying to save the value of sn and pn in an instance variable of object Container: NSNumber *sn, NSNumber *pn. I want it so that when my parser get the attributeValues it can save it as a Double (or float) in those NSNumber pointers. Right now, all it does it just saves a string to the NSNumber. The Parser Code looks like this: if([elementName isEqualToString:@"book"]){ container = [[Container alloc] init]; container.sn=[attributeDict objectForKey:@"sn"]; container.pn=[attributeDict objectForKey:@"pn"]; } I want it so that the type of container.sn is initialized to a float or double. Any ideas how to do this? Thanks in advance!

  • EXC_BAD_ACCESS in CFAttributedStringSetAttribute and NSNumber?

    - by RichardR
    Hi all, I am getting an infuriating EXC_BAD_ACCESS error in an objective c app I am working on. Any help you could offer would be much appreciated. I have tried the normal debug methods for this error (turning on NSZombieEnabled, checking retain/release/autorelease to make sure I'm not trying to access a deallocated object, etc.) and it hasn't seemed to help. Basically, the error always occurs in this function: ` void op_TJ(CGPDFScannerRef scanner, void *info) { PDFPage *self = info; CGPDFArrayRef array; NSMutableString *tempString = [NSMutableString stringWithCapacity:1]; NSMutableArray *kernArray = [[NSMutableArray alloc] initWithCapacity:1]; if(!CGPDFScannerPopArray(scanner, &array)) { [kernArray release]; return; } for(size_t n = 0; n < CGPDFArrayGetCount(array); n += 2) { if(n >= CGPDFArrayGetCount(array)) continue; CGPDFStringRef pdfString; // if we get a PDF string if (CGPDFArrayGetString(array, n, &pdfString)) { //get the actual string const unsigned char *charstring = CGPDFStringGetBytePtr(pdfString); //add this string to our temp string [tempString appendString:[NSString stringWithCString:(const char*)charstring encoding:[self pageEncoding]]]; //NSLog(@"string: %@", tempString); //get the space after this string CGPDFReal r = 0; if (n+1 < CGPDFArrayGetCount(array)) { CGPDFArrayGetNumber(array, n+1, &r); // multiply by the font size CGFloat k = r; k = -k/1000 * self.tmatrix.a * self.fontSize; CGFloat kKern = self.kern * self.tmatrix.a; k = k + kKern; // add the location and kern to the array NSNumber *tempKern = [NSNumber numberWithFloat:k]; NSLog(@"tempKern address: %p", tempKern); [kernArray addObject:[NSArray arrayWithObjects:[NSNumber numberWithInt:[tempString length] - 1], tempKern, nil]]; } } } // create an attribute string CFMutableAttributedStringRef attString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 10); CFAttributedStringReplaceString(attString, CFRangeMake(0, 0), (CFStringRef)tempString); //apply overall kerning NSNumber *tkern = [NSNumber numberWithFloat:self.kern * self.tmatrix.a * self.fontSize]; CFAttributedStringSetAttribute(attString, CFRangeMake(0, CFAttributedStringGetLength(attString)), kCTKernAttributeName, (CFNumberRef)tkern); //apply individual kern attributes for (NSArray *kernLoc in kernArray) { NSLog(@"kern location: %i, %i", [[kernLoc objectAtIndex:0] intValue],[[kernLoc objectAtIndex:1] floatValue]); CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]); } CFAttributedStringReplaceAttributedString([self cfAttString], CFRangeMake(CFAttributedStringGetLength([self cfAttString]), 0), attString); //release CFRelease(attString); [kernArray release]; } ` The program always crashes because of line CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]) And it seems to depend on a few things: if [kernLoc objectAtIndex:1] refers to an [NSNumber numberWithFloat:k] where k = 0 (in other words, if k = 0 above where I populate kernArray) then the program crashes almost immediately If I comment out the line k = k + kKern, it takes longer for the program to crash, but does eventually (why would the crash depend on this value?) If I change the length of CFRangeMake from 1 to 0, it takes a lot longer for the program to crash, but still eventually does. (I don't think I am trying to access beyond the bounds of attString, but am I missing something?) When it crashes, I get something similar to: #0 0x942c7ed7 in objc_msgSend () #1 0x00000013 in ?? () #2 0x0285b827 in CFAttributedStringSetAttribute () #3 0x0000568f in op_TJ (scanner=0x472a590, info=0x4a32320) at /Users/Richard/Desktop/AppTest/PDFHighlight 2/PDFScannerOperators.m:251 Any ideas? It seems like somewhere along the way I am overwriting memory or trying to access memory that has been changed, but I have no idea. If there's anymore information I can provide, please let me know. Thanks, Richard

  • Setting corelocation results to NSNumber object parameters

    - by Dan Ray
    This is a weird one, y'all. - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocationCoordinate2D coordinate = newLocation.coordinate; self.mark.longitude = [NSNumber numberWithDouble:coordinate.longitude]; self.mark.latitude = [NSNumber numberWithDouble:coordinate.latitude]; NSLog(@"Got %f %f, set %f %f", coordinate.latitude, coordinate.longitude, self.mark.latitude, self.mark.longitude); [manager stopUpdatingLocation]; manager.delegate = nil; if (self.waitingForLocation) { [self completeUpload]; } } The latitude and longitude in that "mark" object are synthesized parameters referring to NSNumber iVars. In the simulator, my NSLog output for that line in the middle there reads: 2010-05-28 15:08:46.938 EverWondr[8375:207] Got 37.331689 -122.030731, set 0.000000 -44213283338325225829852024986561881455984640.000000 That's a WHOLE lot further East than 1 Infinite Loop! The numbers are different on the device, but similar--lat is still zero and long is a very unlikely high negative number. Elsewhere in the controller I'm accepting a button press and uploading a file (an image I just took with the camera) with its geocoding info associated, and I need that self.waitingForLocation to inform the CLLocationManager delegate that I already hit that button and once its done its deal, it should go ahead and fire off the upload. Thing is, up in the button-click-receiving method, I test see if CL is finished by testing self.mark.latitude, which seems to be getting set zero...

  • Correctly assigning value to a Core Data attribute with an integer data-type

    - by Gordon Fontenot
    I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --Edit 1-- Ok, so I can get rid of the warning by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber? --Edit 2-- Ok, so I'm realizing that there is some fundamental idea that I don't understand. I now understand that the 60 million + number can be cast back to the correct 0-5 number by using integerValue. So, it seems my question is how can I save an integer between 0-5 to the attribute if the NSNumber that is returned is over 60 million? Do I need to be using a different data type?

  • 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. All of a sudden I'm now dumbfounded by an error. 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 once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

  • Slider Not Behaving As I Would Expect

    I have a slider that changes a float from 1 to 10 but I want to save this value and use it across all view controllers so I have saved that float as an NSNumber in a model class (settingsData.sensitivitySliderSettingValue). I am trying to output the updated slider value to the console every time that it is changed however it just gets set to 0 rather than 0 to 10. I don't understand why this is... Here's my code: -(IBAction)sensitivitySliderValueChanged:(id)sender { [self updateSensitivity]; } -(void)updateSensitivity{ settingsData.sensitivitySettingValue = [NSNumber numberWithFloat:sensitivitySlider.value]; NSLog(@"The Slider Value is: %1.1f", [settingsData.sensitivitySettingValue floatValue]); }

  • Why does my program crash when given negative values?

    - by Wayfarer
    Alright, I am very confused, so I hope you friends can help me out. I'm working on a project using Cocos2D, the most recent version (.99 RC 1). I make some player objects and some buttons to change the object's life. But the weird thing is, the code crashes when I try to change their life by -5. Or any negative value for that matter, besides -1. NSMutableArray *lifeButtons = [[NSMutableArray alloc] init]; CCTexture2D *buttonTexture = [[CCTextureCache sharedTextureCache] addImage:@"Button.png"]; LifeChangeButtons *button = nil; //top left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , size.height - 30); [button buttonText:-5]; [lifeButtons addObject:button]; //top right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , size.height - 30); [button buttonText:1]; [lifeButtons addObject:button]; //bottom left button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(50 , 30); [button buttonText:5]; [lifeButtons addObject:button]; //bottom right button = [LifeChangeButtons lifeButton:buttonTexture ]; button.position = CGPointMake(size.width - 50 , 30); [button buttonText:-1]; [lifeButtons addObject:button]; for (LifeChangeButtons *theButton in lifeButtons) { [self addChild:theButton]; } This is the code that makes the buttons. It simply makes 4 buttons, puts them in each corner of the screen (size is the screen) and adds their life change ability, 1,-1,5, or -5. It adds them to the array and then goes through the array at the end and adds all of them to the screen. This works fine. Here is my code for the button class: (header file) // // LifeChangeButtons.h // Coco2dTest2 // // Created by Ethan Mick on 3/14/10. // Copyright 2010 Wayfarer.

"); //this is where we change the life to each selected player NSLog(@"Test1"); NSMutableArray *tempArray = [[[UIApplication sharedApplication] delegate] selectedPlayerObjects]; NSLog(@"Test2"); for (CustomCCNode *aPlayer in tempArray) { NSLog(@"we change the life by %d.", [lifeChange intValue]); [aPlayer changeLife:[lifeChange intValue]]; } NSLog(@"Test3"); return YES; } - (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchPoint = [touch locationInView:[touch view]]; touchPoint = [[CCDirector sharedDirector] convertToGL:touchPoint]; NSLog(@"You moved in a button!"); } - (void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { NSLog(@"You touched up in a button"); } @end Now, This function: - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event Is where all the shit goes down. It works for all of the buttons except the -5 one. And then, it gets to: NSLog(@"we change the life by %d.", [lifeChange integerValue]); And it crashes at that statement. It only crashes when given anything less than -1. -1 works, but nothing smaller does. Here is the code in the CustomCCNode Class, "changeLife" that is being called. - (void)changeLife:(int)lifeChange { NSLog(@"change life in Custom Class was called"); NSLog(@"wtf is lifechange: %d", lifeChange); life += lifeChange; lifeString = [[NSString alloc] initWithFormat:@"%d",life]; [text setString:lifeString]; } Straight forward, but when the NSnumber is -5, it doesn't even get called, it crashes at the NSlog statement. So... what's up with that?

  • Transform.Translation problem on rotation

    I am using the following to scale and reposition a UIView layer when the device rotates to landscape. [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.x"]; [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.y"]; [containerView.layer setValue:[NSNumber numberWithFloat: 1] forKeyPath: @"transform.scale.x"]; //[NSNumber numberWithInt:1] [containerView.layer setValue:[NSNumber numberWithFloat: 1] forKeyPath: @"transform.scale.y"]; and then the folowing when rotating back to portrait [containerView.layer setValue:[NSNumber numberWithFloat: -75] forKeyPath: @"transform.translation.x"]; [containerView.layer setValue:[NSNumber numberWithFloat: 0] forKeyPath: @"transform.translation.y"]; [containerView.layer setValue:[NSNumber numberWithFloat: .7] forKeyPath: @"transform.scale.x"]; //[NSNumber numberWithInt:1] [containerView.layer setValue:[NSNumber numberWithFloat: .7] forKeyPath: @"transform.scale.y"]; The problem is that after rotaing back to portrait, the layer is 'travelling' ie the x,y offset are gradually changing(increasing x, decreasing y). Scale seems fine (ie doesn't increment, decrement on repeated rotations) Can anyone suggest a proper solution?

  • Creating Gun objects with upgrades?

    - by zardon
    I have a series of guns in my game. I use the Gun class/object like this: (Just an example) @interface Gun : NSObject { NSString *name; // Six-shooter NSNumber *cost; NSNumber *clipPrice; // ie: 700 NSNumber *clipCapacity; // 6 NSNumber *ammoCapacity; // 6 NSNumber *damage; // 0-10 NSNumber *accuracy; // 0-10 NSNumber *fireRate; // 0-10 NSNumber *range; // 0-10 // Not sure if I have all the stats, but this is fine for now } Lets say I want to have 3 upgrades per gun. My problem is I am not sure how to do this. Examples: increase fire-rate increase range increase accuracy silencer double ammo capacity (ie: Drum) double clip capacity (ie: Taped magazine) Thus my question is, I'd like to implement an upgrade system to guns but I am not sure how to do it. Would there be an Upgrade object which is a child to the Gun class, or would it be seperate class altogether. Thanks for your time.
