  • How can I add a header folder to my project?

    - by VansFannel
    I'm developing an iOS application with latest Xcode 4.5.2. I have the following folder structure: /.../SourceCode/MyProjectFolder/projectName.xcodeproject /.../SourceCode/MyProjectFolder/projectName/ /.../SourceCode/MyProjectFolder/projectName/xxx.m /.../SourceCode/MyProjectFolder/projectName/xxx.h /.../SourceCode/MyProjectFolder/projectName/PVRT/ /.../SourceCode/MyProjectFolder/projectName/PVRT/header1.h /.../SourceCode/MyProjectFolder/projectName/PVRT/OtherFolder/header2.h If in my header files I add this: #include "header1.h" I get a "header1.h" not found error. But, if I add: #include "PVRT/header1.h" I get a "header2.h" not found. On project settings I have add the following path: ${SOURCE_ROOT}/projectName/PVRT But I'm getting the same error. How can I fix this?

  • Should we point to an NSManagedObject entity with weak instead of strong pointer?

    - by Jim Thio
    I think because NSManagedObject is managed by the managedObject context the pointer should be weak. Yet it often goes back to 0 in my cases. for (CategoryNearby * CN in sorted) { //[arrayOfItems addObject:[NSString stringWithFormat:@"%@ - %d",CN.name,[CN.order intValue]]]; NearbyShortcutTVC * tvc=[[NearbyShortcutTVC alloc]init]; tvc.categoryNearby =CN; // tvc.titleString=[NSString stringWithFormat:@"%@",CN.name]; // tvc.displayed=CN.displayed; [arrayOfItemsLocal addObject:tvc]; //CN PO(tvc); PO(tvc.categoryNearby); while (false); } self.arrayOfItems = arrayOfItemsLocal; PO(self.categoriesNearbyInArrayOfItems); [self.tableViewa reloadData]; ... Yet somewhere down the line: tvc.categoryNearby becomes nil. I do not know how or when or where it become nil. How do I debug this? Or should the reference be strong instead? This is the interface of NearbyShortcutTVC by the way @interface NearbyShortcutTVC : BGBaseTableViewCell{ } @property (weak, nonatomic) CategoryNearby * categoryNearby; @end To make sure that we're talking about the same object I print all the memory addresses of the NSArray They're both the exact same object. But somehow the categoryNearby property of the object is magically set to null somewhere. self.categoriesNearbyInArrayOfItems: ( 0x883bfe0, 0x8b6d420, 0x8b6f9f0, 0x8b71de0, 0xb073f90, 0xb061a10, 0xb06a880, 0x8b74940, 0x8b77110, 0x8b794e0, 0x8b7bf40, 0x8b7cef0, 0x8b7f4b0, 0x8b81a30, 0x88622d0, 0x8864e60, 0xb05c9a0 ) self.categoriesNearbyInArrayOfItems: ( 0x883bfe0, 0x8b6d420, 0x8b6f9f0, 0x8b71de0, 0xb073f90, 0xb061a10, 0xb06a880, 0x8b74940, 0x8b77110, 0x8b794e0, 0x8b7bf40, 0x8b7cef0, 0x8b7f4b0, 0x8b81a30, 0x88622d0, 0x8864e60, 0xb05c9a0 )

  • UIView to Form Sheet flip animation rotation issue

    - by GSD
    I have this view to form sheet flip animation that works great in portrait mode but not in any other orientations. In my code, I use it with a UIView embedded in another UIView, which is in the root view. The animation will be rotated. Anyone has an idea why? - (void)presentModalViewControllerWithFlipAnimation:(UIViewController *)modalViewController fromView:(UIView *)fromView { UIWindow* window = [[UIApplication sharedApplication] windows][0]; _fromViewSnapshot = [[UIImageView alloc] initWithFrame:fromView.bounds]; UIGraphicsBeginImageContext(fromView.bounds.size); [fromView.layer renderInContext:UIGraphicsGetCurrentContext()]; [_fromViewSnapshot setImage:UIGraphicsGetImageFromCurrentImageContext()]; [_fromViewSnapshot sizeToFit]; UIGraphicsEndImageContext(); _fromViewSnapshot.autoresizesSubviews = YES; _fromViewSnapshot.frame = [fromView.superview convertRect:fromView.frame toView:window]; [window addSubview:_fromViewSnapshot]; fromView.hidden = YES; modalViewController.modalPresentationStyle = UIModalPresentationFormSheet; [self presentViewController:modalViewController animated:NO completion:nil]; UIView __weak *presentedView = modalViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIView __weak *presentationSuperview = presentedView.superview; [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; [_fromViewSnapshot.superview bringSubviewToFront:_fromViewSnapshot]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ _fromViewSnapshot.frame = [_fromViewSnapshot.superview convertRect:presentedView.frame fromView:presentationSuperview]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:_fromViewSnapshot duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromRight animations: ^{ presentationSnapshotView.frame = _fromViewSnapshot.bounds; [_fromViewSnapshot addSubview:presentationSnapshotView]; } completion:^(BOOL finished) { [presentationSuperview addSubview:presentedView]; [presentationSnapshotView removeFromSuperview]; [_fromViewSnapshot removeFromSuperview]; }]; }]; } - (void)dismissViewControllerWithFlipAnimation:(UIView*)fromView completion:(void (^)(void))completion { UIWindow* window = [[UIApplication sharedApplication] windows][0]; UIView __weak *presentedView = self.presentedViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; presentationSnapshotView.frame = presentedView.frame; [window addSubview:presentationSnapshotView]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ presentationSnapshotView.frame = [fromView.superview convertRect:fromView.frame toView:window]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:presentationSnapshotView duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromLeft animations: ^{ _fromViewSnapshot.frame = presentationSnapshotView.bounds; [presentationSnapshotView setImage:[(UIImageView*)_fromViewSnapshot image]]; [self dismissViewControllerAnimated:NO completion:nil]; } completion:^(BOOL finished) { [presentationSnapshotView removeFromSuperview]; _fromViewSnapshot = nil; completion(); }]; }]; }

  • Parsing CSV: how can NSScanner recognize empty field (i.e. ,,)?

    - by Fabrizio Prosperi
    I am very new to Xcode and trying - as millions - to parse a CSV file. I have read many contributions and I am managing it but I have a problem when my NSScanner intercepts an empty field: "Field_A, Field_B,, Field_D". I guess it is because it ignores empty space by default, or in this case no space at all. String is: "Personal","2011-01-01","Personal","Cigarettes",,4.60,"Cash","", I tried to debug it using scanLocation: 2011-04-22 15:57:32.414 Spending[42015:a0f] Before while...scan location is:0 2011-04-22 15:57:32.414 Spending[42015:a0f] Account: "Personal" - scan location is:10 2011-04-22 15:57:32.415 Spending[42015:a0f] Date: "2011-01-01" - scan location is:23 2011-04-22 15:57:32.415 Spending[42015:a0f] Category: "Personal" - scan location is:34 2011-04-22 15:57:32.416 Spending[42015:a0f] Subcategory: "Cigarettes" - scan location is:47 2011-04-22 15:57:32.416 Spending[42015:a0f] Income: 4.600000 - scan location is:53 2011-04-22 15:57:32.416 Spending[42015:a0f] Expense: 0.000000 - scan location is:53 2011-04-22 15:57:32.417 Spending[42015:a0f] Payment: "Cash" - scan location is:60 2011-04-22 15:57:32.417 Spending[42015:a0f] Note: "" - scan location is:63 And as you can see after that even expense field gets no value (should be 4.60). Here is the relevant piece of code: NSScanner *scanner = [NSScanner scannerWithString:fileString]; [scanner setCharactersToBeSkipped: [NSCharacterSet characterSetWithCharactersInString:@"\n, "]]; NSString *account, *date, *category, *subcategory, *payment, *note; float income, expense; // Set up data delimiter using comma NSCharacterSet *commaSet; commaSet = [NSCharacterSet characterSetWithCharactersInString:@","]; NSLog (@"Before while...scan location is:%d\n", scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&account]; NSLog(@"Account: %@ - scan location is:%d\n",account, scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&date]; NSLog(@"Date: %@ - scan location is:%d\n",date, scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&category]; NSLog(@"Category: %@ - scan location is:%d\n",category, scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&subcategory]; NSLog(@"Subcategory: %@ - scan location is:%d\n",subcategory, scanner.scanLocation); [scanner scanFloat:&income]; NSLog(@"Income: %f - scan location is:%d\n",income, scanner.scanLocation); [scanner scanFloat:&expense]; NSLog(@"Expense: %f - scan location is:%d\n",expense, scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&payment]; NSLog(@"Payment: %@ - scan location is:%d\n",payment, scanner.scanLocation); [scanner scanUpToCharactersFromSet:commaSet intoString:&note]; NSLog(@"Note: %@\n - scan location is:%d",note, scanner.scanLocation); I tried looking carefully through NSScanner Class Reference, but could not get an idea? Do you have any? Thanks, Fabrizio.

  • iPhone/Obj-C - Archiving object causes lag

    - by Dylan
    Hi I have a table view, and when I delete a cell I am removing an item from an NSMutableArray, archiving that array, and removing the cell. However, when I do this, it is causing the delete button to lag after I click it. Is there any way to fix this? // Override to support editing the table view. - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { int row = [indexPath row]; [savedGames removeObjectAtIndex:row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; //this line causing lag [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } Thanks

  • 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.

  • Why I can't called my doSomething method?

    - by Tattat
    This is my DrawSomethingCmd: #import "Command.h"; @interface DrawSomethingCmd : Command { } -(void)doSomething; -(void)execute; @end and the DrawSomethingCmd.m's doSomething method is like that: -(void)doSomething{ NSLog(@"did"); } The Command.h: #import <Foundation/Foundation.h> @interface Command : NSObject { } -(void)execute; And the Command.m: #import "Command.h" @implementation Command -(id)init{ return self; } -(void)execute{ } @end And I have the method like this: DrawSomethingCmd *tempCmd = [[DrawSomethingCmd alloc] init]; [tempCmd doSomething]; But my Console did't show any things on that, what's going on?

    - by coure06
    i have to animate text around a circle. The text will also scale up/down. Whats the best approach to accomplish this? (i am using Quartz 2D) My approach is: -- Calculate point using sin and cos methods. -- Move Pen there and draw text with alpha and size. -- Clear the screen -- Calculate next point using sin and cos methods. -- Move pen there and draw text with alpha and size. -- clear the screen so on... any better way?

  • How to store array of NSManagedObjects in an NSManagedObject

    - by David Tay
    I am loading my app with a property list of data from a web site. This property list file contains an NSArray of NSDictionaries which itself contains an NSArray of NSDictionaries. Basically, I'm trying to load a tableView of restaurant menu categories each of which contains menu items. My property list file is fine. I am able to load the file and loop through the nodes structure creating NSEntityDescriptions and am able to save to Core Data. Everything works fine and expectedly except that in my menu category managed object, I have an NSArray of menu items for that category. Later on, when I fetch the categories, the pointers to the menu items in a category is lost and I get all the menu items. Am I suppose to be using predicates or does Core Data keep track of my object graph for me? Can anyone look at how I am loading Core Data and point out the flaw in my logic? I'm pretty good with either SQL and OOP by themselves, but am a little bewildered by ORM. I thought that I should just be able to use aggregation in my managed objects and that the framework would keep track of the pointers for me, but apparently not. NSError *error; NSURL *url = [NSURL URLWithString:@"http://foo.com"]; NSArray *categories = [[NSArray alloc] initWithContentsOfURL:url]; NSMutableArray *menuCategories = [[NSMutableArray alloc] init]; for (int i=0; i<[categories count]; i++){ MenuCategory *menuCategory = [NSEntityDescription insertNewObjectForEntityForName:@"MenuCategory" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *category = [categories objectAtIndex:i]; menuCategory.name = [category objectForKey:@"name"]; NSArray *items = [category objectForKey:@"items"]; NSMutableArray *menuItems = [[NSMutableArray alloc] init]; for (int j=0; j<[items count]; j++){ MenuItem *menuItem = [NSEntityDescription insertNewObjectForEntityForName:@"MenuItem" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *item = [items objectAtIndex:j]; menuItem.name = [item objectForKey:@"name"]; menuItem.price = [item objectForKey:@"price"]; menuItem.image = [item objectForKey:@"image"]; menuItem.details = [item objectForKey:@"details"]; [menuItems addObject:menuItem]; } [menuCategory setValue:menuItems forKey:@"menuItems"]; [menuCategories addObject:menuCategory]; [menuItems release]; } if (![[self managedObjectContext] save:&error]) { NSLog(@"An error occurred: %@", [error localizedDescription]); }

  • How To Read A Remote Text File

    - by XcodeDev
    Hi, I would like to read a remote text file called posts.txt on my website. An example of the insides of the posts.txt file would be this: <div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by iSDK</i></font><br><img src="Bar.png" /></div><div style="width : 300px; position : relative"><font face="helvetica, geneva, sans serif" size="6"><b>2</b></font><font face="helvetica, geneva, sans serif" size="4"><i> scored by martin</i></font><br><img src="Bar.png" /></div> What I wanted to know is how can I get the score, and scored by text from the .txt file? The score is (in this case) the: <b>2</b>, and the scored by text in this case would be: "scored by iSDK". Any code telling me how to do this is twice as helpful! Thanks in advanced XcodeDev

  • NSXMLParser 's delegate and memory leak

    - by dizzy_fingers
    Hello, I am using a NSXMLParser class in my program and I assign a delegate to it. This delegate, though, gets retained by the setDelegate: method resulting to a minor, yet annoying :-), memory leak. I cannot release the delegate class after the setDelegate: because the program will crash. Here is my code: self.parserDelegate = [[ParserDelegate alloc] init]; //retainCount:1 self.xmlParser = [[NSXMLParser alloc] initWithData:self.xmlData]; [self.xmlParser setDelegate:self.parserDelegate]; //retainCount:2 [self.xmlParser parse]; [self.xmlParser release]; ParserDelegate is the delegate class. Of course if I set 'self' as the delegate, I will have no problem but I would like to know if there is a way to use a different class as delegate with no leaks. Thank you in advance.

  • Autorelease and properties

    - by ganuke
    I have few questions to ask about the following class #import <Cocoa/Cocoa.h> @interface SomeObject { NSString *title; } @property (retain) NSString *title; @end implementation SomeObject @synthesize title; -(id)init { if (self=[super init]) { self.title=[NSString stringWithFormat:@"allyouneed"]; } return self; } -(void)testMethod{ self.title=[[NSString alloc] init] ; } -(void)dealloc { self.title=nil; [super dealloc]; } In the .h file do we need to declare the title and sub when we add the property. is it not enough to add the @property (retain) NSString *title; line. 2.Do i need to autorelease both assignment to title in the init and testMethod. if So why? Can some one explain these things to me.

  • Command line tool (PDF Workflow) in OSX that detects if key is down

    - by kroko
    Hello! I'm writing a OSX PDF Workflow in ObjC and C. A single executable ("UNIX Tool" as named in the Apple reference), that reads in the spooled PDF file, does some parsing. I'd like to give more functionality by enabling a key-down event handling, meaning - when user opens print dialog in an application - and chooses to left-mouse-click on the custom made pdf workflow to run it - depending on if a keyboard key is down (i.e. option key, but "any key down" would be enough for me) when running that workflow - a decision is made in the code. I have read NSEvent and Carbon Event Manager reference and it seems that in this case (a plain unix executable + not run as root) it's not possible. Or is it? Many thanks in advance, Kroko

  • Search pattern in string using regex in obj-c

    - by manileo86
    I'm working on a string pattern match algorithm. I use NSRegularExpression for finding the matches. For ex: I've to find all words starting with '#' in a string.. Currently I use the following regex function: static NSRegularExpression *_searchTagRegularExpression; static inline NSRegularExpression * SearchTagRegularExpression() { if (!_searchTagRegularExpression) { _searchTagRegularExpression = [[NSRegularExpression alloc] initWithPattern:@"(?<!\\w)#([\\w\\._-]+)? options:NSRegularExpressionCaseInsensitive error:nil]; } return _searchTagRegularExpression; } and I use it as below: NSRegularExpression *regexp = SearchTagRegularExpression(); [regexp enumerateMatchesInString:searchString options:0 range:stringRange usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) { // comes here for every match with range }]; This works properly. But i just want to know if this is the best way. suggest if there's any better alternative...

  • Set text equal to string and pass to receipt printer at a different size on iOS

    - by Max Roper
    I am using the StarIO SDK to print text to a receipt printer and I am trying to get a certain line of text larger than the rest. I have some help from their support but I can't really get it to go. -(void)print{ NSMutableString *final=[NSMutableString stringWithFormat:@"-----"]; [final appendFormat:@"\n\nLevel:%@ Section:%@ Row:%@ Seat:%@", [response_dict objectForKey:@"level"], [response_dict objectForKey:@"section"],[response_dict objectForKey:@"row"],[response_dict objectForKey:@"seat"]]; There is a bunch of other stuff that is printing, but that is the line that I would like to be a different size than the rest. The StarIO support said that I should try and pass that to this... -(IBAction)PrintText { NSString *portName = [IOS_SDKViewController getPortName]; NSString *portSettings = [IOS_SDKViewController getPortSettings]; [PrinterFunctions PrintTextWithPortname:portName portSettings:portSettings heightExpansion:heightExpansion widthExpansion:widthExpansion textData:textData textDataSize:[textNSData length]]; free(textData); } Would love some help if possible. :) Thanks so much. This is the main bit I think I would need from the StarIO Text formatting doc... - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { array_hieghtExpansion = [[NSMutableArray alloc] init]; [array_hieghtExpansion addObject:@"1"]; [array_hieghtExpansion addObject:@"2"]; [array_hieghtExpansion addObject:@"3"]; [array_hieghtExpansion addObject:@"4"]; [array_hieghtExpansion addObject:@"5"]; [array_hieghtExpansion addObject:@"6"]; array_widthExpansion = [[NSMutableArray alloc] init]; [array_widthExpansion addObject:@"1"]; [array_widthExpansion addObject:@"2"]; [array_widthExpansion addObject:@"3"]; [array_widthExpansion addObject:@"4"]; [array_widthExpansion addObject:@"5"]; [array_widthExpansion addObject:@"6"]; array_alignment = [[NSMutableArray alloc] init]; [array_alignment addObject:@"Left"]; [array_alignment addObject:@"Center"]; [array_alignment addObject:@"Right"]; } return self; } and int heightExpansion = [pickerpopup_heightExpansion getSelectedIndex]; int widthExpansion = [pickerpopup_widthExpansion getSelectedIndex];

  • EXC_BAD_ACCESS when simply casting a pointer in Obj-C

    - by AlexChilcott
    Hi all, Frequent visitor but first post here on StackOverflow, I'm hoping that you guys might be able to help me out with this. I'm fairly new to Obj-C and XCode, and I'm faced with this really... weird... problem. Googling hasn't turned up anything whatsoever. Basically, I get an EXC_BAD_ACCESS signal on a line that doesn't do any dereferencing or anything like that that I can see. Wondering if you guys have any idea where to look for this. I've found a work around, but no idea why this works... The line the broken version barfs out on is the line: LevelEntity *le = entity; where I get my bad access signal. Here goes: THIS VERSION WORKS NSArray *contacts = [self.body getContacts]; for (PhysicsContact *contact in contacts) { PhysicsBody *otherBody; if (contact.bodyA == self.body) { otherBody = contact.bodyB; } if (contact.bodyB == self.body) { otherBody = contact.bodyA; } id entity = [otherBody userData]; if (entity != nil) { LevelEntity *le = entity; CGPoint point = [contact contactPointOnBody:otherBody]; } } THIS VERSION DOESNT WORK NSArray *contacts = [self.body getContacts]; for (NSUInteger i = 0; i < [contacts count]; i++) { PhysicsContact *contact = [contacts objectAtIndex:i]; PhysicsBody *otherBody; if (contact.bodyA == self.body) { otherBody = contact.bodyB; } if (contact.bodyB == self.body) { otherBody = contact.bodyA; } id entity = [otherBody userData]; if (entity != nil) { LevelEntity *le = entity; CGPoint point = [contact contactPointOnBody:otherBody]; } } Here, the only difference between the two examples is the way I enumerate through my array. In the first version (which works) I use for (... in ...), where as in the second I use for (...; ...; ...). As far as I can see, these should be the same. This is seriously weirding me out. Anyone have any similar experience or idea whats going on here? Would be really great :) Cheers, Alex

  • release viewcontroller after presenting modally

    - by Jonathan
    I was watching CS193P Stanford course on Itunes, and in one of the lectures a demo was given and There it was said you could present the viewcontroller modally and then release it. Roughly like this (I know this isn't perfect but I'm on my PC atm) [self.view presentcontentmodally:myVC] [myVC release]; However this seems to produce problems. If I put a NSLog(@"%d", [myVC retainCount]) between those two lines then it returns 2 implying it is ok to release. However when I dismiss the myVC the app crashes. Nothing in the NSlog and the debugger won't show where it stopped. But I used malloc-history or something that some blog said would help. And found that it was the myVC. So should I be releasing myVC? (also when the modalVC has been dissmissed should the app's memory usuage go back to before the modalVC was presented?)

  • iPhone MVC Question

    - by HM1
    Hi, I'm bit of a newbie and had a basic question regarding adhering to the MVC model in iPhone coding. How do I setup a Model class that holds my data and connect it to different controllers in the following setup: Using Interface Builder, I created a tab controller in which - Tab #1 has a Nav Controller and a hierarchy of View Controllers. - Tab #2 has a View Controller So with what I have now, the View Controller under Tab #1 alloc init's the model class and I know how to pass the model from one ViewController to the next in the Navigation Hierarchy where it can pass the data and/or be updated with new data. Question is how to pass it from Tab #1's View Controller to Tab #2 View Controller as there is no code linking the two??? Thanks in advance, Hiren.
