  • Call AppDelegate Method from Class

    - by golfromeo
    Basically, I need to call a method in my AppDelegate from one of my view controller classes. Currently, I'm doing the following: myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate doMethod]; And including the myAppDelegate.h at the top of the .m file of the class: #import "myAppDelegate.h" When I run it, everything works... But I get the following warning: warning 'myAppDelegate' may not respond to '-doMethod' Is there another way that I should reference the app delegate? Thanks for any help in advance.

  • XCode enum woes

    - by Raconteur
    Hi gang, I thought I had this sorted, but I am still missing something. Very simply, I have a Settings class that hold a DAO (sitting on a plist). I want to have a couple of enums for the settings for convenience and readability, such as GamePlayType and DifficultyLevel. Right now I am defining them in the Settings.h file above the @interface line as such: typedef enum { EASY, NORMAL, HARD } DifficultyLevel; and typedef enum { SET_NUMBER_OF_MOVES, TO_COMPLETION } GamePlayType; If I access them from within the Settings class like: - (int)gridSizeForLOD { switch ([self difficultyLevel]) { case EASY: return GRID_SIZE_EASY; case NORMAL: return GRID_SIZE_NORMAL; case HARD: return GRID_SIZE_HARD; default: return GRID_SIZE_NORMAL; } } everything is fine. But, if I try to access them outside of the Settings class, let's say in my main view controller class, like this: if (([settings gameType] == SET_NUMBER_OF_MOVES) && (numMoves == [settings numMovesForLOD])) { [self showLoseScreen]; } I get errors (like EXC_BAD_ACCESS) or the condition always fails. Am I doing something incorrectly? Also, I should point out that I have this code for the call to gameType (which lives in the Settings class): - (GamePlayType)gameType { return [dao gameType]; } and the DAO implements gameType like this: - (int)gameType { return (settingsContent != nil) ? [[settingsContent objectForKey:@"Game Type"] intValue] : 0; } I know I have the DAO returning an int instead of a GamePlayType, but A) the problem I am describing arose there when I tried to use the "proper" data type, and B) I did not think it would matter since the enum is just a bunch of named ints, right? Any help, greatly appreciated. I really want to understand this thoroughly, and something is eluding me... Cheers, Chris

  • Correcting a plist with dictionaries

    - by ingenspor
    Plist is copyed to documents directory if it doesn't exist. If it already exists, I want to use the "Name" key from NSDictionary in bundleArray to find the matching NSDictionary in documentsArray. When the match is found, I want to check for changes in the strings and replace them if there is a change. If a match is not found it means this dictionary must be added to documents plist. This is my code: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self managePlist]; return YES; } - (void)managePlist { NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Objects.plist"]; NSString *bundle = [[NSBundle mainBundle] pathForResource:@"Objects" ofType:@"plist"]; NSFileManager *fileManager = [NSFileManager defaultManager]; if (![fileManager fileExistsAtPath: path]) { [fileManager copyItemAtPath:bundle toPath:path error:&error]; } else { NSArray *bundleArray = [[NSArray alloc] initWithContentsOfFile:bundle]; NSMutableArray *documentArray = [[NSMutableArray alloc] initWithContentsOfFile:path]; BOOL updateDictionary = NO; for(int i=0;i<bundleArray.count;i++) { NSDictionary *bundleDict=[bundleArray objectAtIndex:i]; BOOL matchInDocuments = NO; for(int ii=0;ii<documentArray.count;ii++) { NSMutableDictionary *documentDict = [documentArray objectAtIndex:ii]; NSString *bundleObjectName = [bundleDict valueForKey:@"Name"]; NSString *documentsObjectName = [documentDict valueForKey:@"Name"]; NSRange range = [documentsObjectName rangeOfString:bundleObjectName options:NSCaseInsensitiveSearch]; if (range.location != NSNotFound) { matchInDocuments = YES; } if (matchInDocuments) { if ([bundleDict objectForKey:@"District"] != [documentDict objectForKey:@"District"]) { [documentDict setObject:[bundleDict objectForKey:@"District"] forKey:@"District"]; updateDictionary=YES; } } else { [documentArray addObject:bundleDict]; updateDictionary=YES; } } } if(updateDictionary){ [documentArray writeToFile:path atomically:YES]; } } } If I run my app now I get this message: '-[__NSCFDictionary setObject:forKey:]: mutating method sent to immutable object' How can I fix this? When this is fixed, do you think my code will work? If not, I would be happy for some suggestions on how to do this. I have struggled for a while and really need to publish the update with the corrections! Thanks a lot for your help.

  • iOS6: do we have to set rootViewController in App delegate in order to support different orientations?

    - by Centurion
    The app was perfectly fine working in iOS5 in landscape orientation. However in iOS6, it started to use portrait orientation in all view controllers. The methods shouldAutorotateToInterfaceOrientation are not called anymore. I read the new stuff about changed rotation mechanism in iOS6 and I was able to fix that by adding a line in my AppDelegate: self.window.rootViewController = _viewController _viewControler is the starting screen (Home-menu). All other view controllers implement shouldAutorotateToInterfaceOrientation method and returns YES for landscape orientations only. So, it's perfectly working solution for the app that needs to support only one orientation. However, the problem is I need one view controller (lets call it phone-VC) to be presented in portrait orientation. Now, if I want this view controller would be rotated then I need to return YES in Home-menu controller that is assigned to rootViewControler in appDelegate. However, I can't do that because this rootViewController is starting window that need to presented in landscape only, otherwise the layout with graphics in this window will break. But if I don't return YES from its shouldAutorotateToInterfaceOrientation (Home-menu) then the same method is not called in my view phone-VC that needs to be presented in portrait. Any ideas? Does the assignation of rootViewController is mandatory in AppDelegate? UPDATE: the problem exists on device (at least on iPhone4).

  • 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.

  • Custom UIButton + subviews = no events

    - by user281300
    Basically I have a custom UIButton and this custom button contains subviews. If I add those subviews to my uibutton, then the button stops responding to event changes. I.e if I click on it it doesn't respond to the selector. I have everything set as userInteractionEnabled. I also tried adding touchbegan and this is working. If I remove those subviews, the UIButton works again. Any help would be greatly appreciated. Cheers.

  • Cocoa Scripting Bridge and <contents> element

    - by Stephen
    So, the application I'm trying to script has a scripting definition file that includes a <contents> element, which is an "implicitly specified container." The question, how do I get at what's inside this element using Scripting Bridge? Or alternatively, how do I send the Apple Event necessary to retrieve it and then transform what I get back into an SBObject? I already tried: [document nameOfKey] document.nameofKey [document contents] document.contents

  • Why am I getting a EXC_BAD_ACCESS in a NSTimer selector?

    - by AngeDeLaMort
    I've got quite a weird problem. To make it short, i'll write some pseudo-code: init: create a dictionary and insert n elements. create a "repeat timer" and add it to the currentRunLoop using the timerRefresh selector. timerRefresh: using a list of keys, find the items in the dictionary if the item exists -> call a function So, for an unknown reason, I get an EXC_BAD_ACCESS when I do: [item function]; But I traced the address I got from the dictionary items and it's ok. The ref count of the items in the dictionary is still 1. The {release, dealloc} of the items in the dictionary aren't called. Everything seems fine. Also, to make it worst, it works for some items. So, I'm wondering if there is a threading problem? or something else obscure? The callstack is quite simple: #0 0x93e0604b in objc_msgSend_fpret #1 0x00f3e6b0 in ?? #2 0x0001cfca in -[myObject functionm:] at myObject.m:000 #3 0x305355cd in __NSFireTimer #4 0x302454a0 in CFRunLoopRunSpecific #5 0x30244628 in CFRunLoopRunInMode #6 0x32044c31 in GSEventRunModal #7 0x32044cf6 in GSEventRun #8 0x309021ee in UIApplicationMain #9 0x000027e0 in main at main.m:14 So, any suggestion where to look would be appreciated.

  • Cant access NString after callback in [NSURLConnection sendSynchronousRequest]

    - by John ClearZ
    Hi I am trying to get a cookie from a site which I can do no problem. The problem arises when I try and save the cookie to a NSString in a holder class or anywhere else for that matter and try and access it outside the delegate method where it is first created. - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { int i; NSString* c; NSArray* all = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:@"http://johncleary.net"]]; //NSLog(@"RESPONSE HEADERS: \n%@", [response allHeaderFields]); for (i=0;i<[all count];i++) { NSHTTPCookie* cc = [all objectAtIndex: i]; c = [NSString stringWithFormat: @"%@=%@", [cc name], [cc value]]; [Cookie setCookie: c]; NSLog([Cookie cookie]) // Prints the cookie fine. } [receivedData setLength:0]; } I can see and print the cookie when I am in the method but I cant when trying to access it form anywhere else even though it gets stored in the holder class @interface Cookie : NSObject { NSString* cookie; } + (NSString*) cookie; + (void) setCookie: (NSString*) cookieValue; @end int main (void) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; JCLogin* login; login = [JCLogin new]; [login DoLogin]; NSLog([Cookie cookie]); // Crashes the program [pool drain]; return 0; }

  • Forward horizontal swipe events on UITableView to parent view

    - by D-Nice
    I have a UITableView that I want to have respond to taps and vertical swipes, but still have something like userInteractionEnabled = NO for horizontal swipes. By that I mean, it would not handle touches and pass the touch event back to its superview. Things I've tried that didn't work: returning NO in - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath Overriding touchesBegan/touchesMoved/touchesEnded and passing the event to the next responder Adding gesture recognizers for horizontal swipes and setting cancelsTouchesInView to YES I've been trying to fix this on and off for several weeks, so any help is greatly appreciated!

  • Is a tab bar configuration view can be customized ?

    - by Dirty Henry
    I have an application with 8 tabbar items in the tabbar controller. Is there a way I can customize the layout of the "... (more)" view in which you can configure which tab bar items should appear in the main tab bar. It seems to be a table view controller but i'd like to use custom cell views and a background image.

  • Sharing NSMutableArray

    - by Lucas Veiga
    Hey everbody, im trying to share a NSMutableArray to another xib. The cartList.codigo is a NSMutableArray from a shared class, according to James Brannan's tutorial (http://www.vimeo.com/12164589). When i count it, it gives me 1. But when i load the another view, gives me 0. Whats wrong? View that adds: self.produtoCodigo = [[NSMutableArray alloc]init]; [self.produtoCodigo addObject:@"aa"]; CartViewController *carrinho = [[CartViewController alloc] initWithNibName:@"CartViewController" bundle:[NSBundle mainBundle]]; CartList *lista = [[CartList alloc] init]; carrinho.cartList = lista; carrinho.cartList.codigo = self.produtoCodigo; NSLog(@"QTD %i", [carrinho.cartList.codigo count]); View that wants to load the item added: - (void) viewDidAppear:(BOOL)animated { self.produtoCodigo = self.cartList.codigo; NSLog(@"%i", [self.produtoCodigo count]); [super viewDidLoad]; } Im loading the CartList class in both. Thanks!

  • Xcode 4: nib files not loading when run, can't find UI elements

    - by Jordan
    So, I just downloaded Xcode 4 and installed it. I was actually quite looking forward to the single window and integrated IB... - However, when I open and run one of my projects, the nib files that the project uses don't seem to load. Instead I'm left looking at a blank white screen (iPhone). This project ran well and fine on Xcode 3.2. So I thought... this can't be that hard to fix. So I opened up a nib file, thinking that maybe editing or creating a new one from scratch could point me in the right direction. But I can't find the old resources panel from interface builder anywhere. How am I meant to create a new view or add buttons? I know I'm probably just missing something obvious :s Did anyone else have the same nib file problems - is there a fix (or something stupidly simple that I'm forgetting about)? - EDIT: Ok. If I background and un-background the app, the view loads fine. But this happens every time I build, on both iPhone and iOS simulator, i.e. the app doesn't work properly until it's been backgrounded. All the code for loading the view follows from - (void)applicationDidFinishLaunching:(UIApplication *)application. Now I am really confused. - Thanks :)
