  • Map resources when added to the project bundle

    - by Espuz
    I have a .h when I map all the image files names and xib names with #defines. For example, if I have an image called "buttonBackground.png" I map it in my .h as #define BUTTON_BACKGROUND_PNG_FILE @"buttonBackground.png" It's possible to detect when a resource is added to the bundle and create the correspond define with a script?

  • What's -mutableSetValueForKey: returning, actually? Is that something special?

    - by dontWatchMyProfile
    From the docs: You usually access to-many relationships using mutableSetValueForKey:, which returns a proxy object that both mutates the relationship and sends appropriate key-value observing notifications for you. So this returns an "intelligent" NSMutableSet which automatically lets the context delete objects when they get deleted from the set, and reverse? Is that a proxy object?

  • Find the end/finish coordinates you a UISwipeGestureRecognizer

    - by Code
    I can find the start coordinates of where a swipe starts by doing the following - (void)oneFingerSwipeUp:(UISwipeGestureRecognizer *)recognizer { CGPoint point = [recognizer locationInView:[self view]]; NSLog(@"Swipe up - start location: %f,%f", point.x, point.y); } Is it possible to find the coordinates where the swipe ended? I looked into the docs and its not mentioned. Is there some work around for this? Many Thanks, -Code

  • recursive enumeration of integer subsets?

    - by KDaker
    I have an NSArray of NSNumbers with integer values such as [1,10,3]. I want to get the sum of all the possible subsets of these numbers. For example for 1,10 and 3 i would get: 1, 10, 3, 1+10=11, 1+3=4, 10+3=13, 1+10+3=14 there are 2^n possible combinations. I understand the math of it but im having difficulties putting this into code. so how can i put this into a method that would take the initial array of numbers and return an array with all the sums of the subsets? e.g -(NSArray *) getSums:(NSArray *)numbers; I understand that the results grow exponentially but im going to be using it for small sets of numbers.

  • NSMutableArray of Objects misbehaves ...

    - by iFloh
    I hope someone understands what happens to my NSMutableArray. I read records a, b, c, d from a database, load the fields into an object an add the object to an array. To do this I read the records into an instance of that object (tmpEvent) and add the Object to the target array (NSMutableArray myArray). the code looks like: for (condition) { tmpEvent.field1 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 0)]; tmpEvent.field2 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 1)]; tmpEvent.field3 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 2)]; NSLog(@"myArray: adding %@", tmpEvent.field1); [myArray addObject:tmpEvent]; } The NSLog shows myArray: adding a myArray: adding b myArray: adding c myArray: adding d Subsequent I enumerate the array (this can be in the same or a different method): for (myObject *records in myArray) { NSLog(@"iEvents value %@", records.field1); } The NSLog now shows: myArray value d myArray value d myArray value d myArray value d a mystery .... ??? any thoughts?

  • How do I remove 3 characters from the end of an NSURL?

    - by saywhatman
    Hey, my first question! I've been able to code up most of this RSS reader without enlisting help (through a lot of searches through stackoverflow!) but I'm stumped here. NSString *urlbase = [[NSString alloc] initWithFormat:[links3 objectAtIndex:indexPath.row]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]]; NSCharacterSet *whitespaces = [NSCharacterSet whitespaceCharacterSet]; NSPredicate *noEmptyStrings = [NSPredicate predicateWithFormat:@"SELF != ''"]; NSArray *parts = [urlbase componentsSeparatedByCharactersInSet:whitespaces]; NSArray *filteredArray = [parts filteredArrayUsingPredicate:noEmptyStrings]; urlbase = [filteredArray componentsJoinedByString:@" "]; NSLog(@"%@ %i" , urlbase, 4353); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]]; The links3 array is a NSMutableArray with strings. The first few lines work flawlessly in eliminating the space at the beginning each string from that array, which is stored in 'urlbase' so they look fine when they come out. When we NSLog urlbase, we see: http://www.feedzilla.com/r/D7E6204FEDBFE541314B997AAB5D2DF9CBA2EFEE But, when we use: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlbase]] We see: http://www.feedzilla.com/r/D7E6204FEDBFE541314B997AAB5D2DF9CBA2EFEE%0A How can I fix this? Can I remove those tail elements somehow? Thanks!

  • How to deal with delegate method calling back the object who send the message ?

    - by olipion
    I have two object: @protocol ObjectADelegate - (void)objectAfirst:(ObjectA *)obj; - (void)objectAsecond:(ObjectA *)obj; @end @interface ObjectA : NSObject { id<ObjectADelegate> delegate; - (void)callSecond { [self.delegate objectAsecond:self]; } @end @interface ObjectB : NSObject <ObjectADelegate>{ ObjectA *myObjectA; } @implementation ObjectB - (void)objectAfirst:(ObjectA *)obj { // First is finished, do second [obj callSecond]; } - (void)objectASecond:(ObjectA *)obj { // Do my stuff } @end As you can see in the code, when ObjectA send the message objectAfirst to its delegate, objectb use again objectA methods that result in objecta calling back objectb. It means that what first fire objectAfirst is not finished but objectA send the objectAsecond message. Could it be a problem ? Any way to let delay message handling in objectB ? for example, something like using [obj performSelector:@selector(callSecond) afterDelay:0.01]; instead of [obj callSecond]; ?

    I am having a hard time getting video to play in an application that I am working on and I think the answer has to do with the views and view controllers. I have the flow depicted below. When the button is clicked, the audio from the video is playing, but nothing is displayed on screen. Anyone have any ideas? -(IBAction) playMovie { Play Movie Code } ViewController UIScrollView UIView UIButton - (playMovie)

  • Why Duplicate the “Release” configuration to "Disctribution"?

    - by Horace Ho
    On the Apple guide, there is a step before building the AppStore version: Open the Xcode project and Duplicate the “Release” configuration in the Configurations pane of the project's Info panel. Rename this new configuration “Distribution”. Why this step is needed? Can I skip this step and use the "Release" configuration to build the final version for AppStore?

  • Unsure how i load the right data into a tableview, chosen from a previous tableview.

    - by Bob
    I currently have two TableViewControllers. The first has seven objects, each day-name listed. Weekdays *mandag = [[Weekdays alloc] initWithName:@"Mandag" daylist:mondayArray]; Weekdays *tirsdag = [[Weekdays alloc] initWithName:@"Tirsdag" daylist:tuesdayArray]; Weekdays *onsdag = [[Weekdays alloc] initWithName:@"Onsdag" daylist:wedensdayArray]; Weekdays *torsdag = [[Weekdays alloc] initWithName:@"Torsdag" daylist:thursdayArray]; Weekdays *fredag = [[Weekdays alloc] initWithName:@"Fredag" daylist:fridayArray]; Weekdays *lordag = [[Weekdays alloc] initWithName:@"Lørdag" daylist:saturdayArray]; Weekdays *sondag = [[Weekdays alloc] initWithName:@"Søndag" daylist:sundayArray]; daylist being a NSMutableArray. The idea is: The name of the day is displayed on table-1. And the array (daylist) of each day is displayed on table-2 - when tabbed one a day. The first table, displaying the names is working fine: VisueltSkemaAppDelegate *appDelegate = (VisueltSkemaAppDelegate *)[[UIApplication sharedApplication] delegate]; Weekdays *ugeDag = (Weekdays *)[appDelegate.ugeDage objectAtIndex:indexPath.row]; cell.textLabel.text = ugeDag.name; return cell; However i thought i could do the same, for the second table - but i have been strugling with it for hours now. This is what i got: VisueltSkemaAppDelegate *appDelegate = (VisueltSkemaAppDelegate *)[[UIApplication sharedApplication] delegate]; Weekdays *ugeDag = (Weekdays *)[appDelegate.ugeDage objectAtIndex:indexPath.row]; cell.textLabel.text = [ugeDag.daylist objectAtIndex:indexPath.row]; return cell; Abit more of the code: http://pastebin.com/iW5AAJXt

    So I've researched extensively on how to list the files in the documents directory in a table view and after much deliberation, came up with this code.

Code is pasted in link below. http://pastie.org/4178767 Edit- App crashes in numberOfRowsInSection: method.

  • How do I push a new controller via UIButton, nested in a UIScrollView?

    - by jimijon
    Hello - I have my views that are part of a tabBar. Each view has a navigationController. In one of my views I have an embeded xib component. This is a scrolling view with UIButtons inside it. I want to slide in another view, inside the navigationController when a person taps the button. I can get the taps, etc. BUT, I can't figure out how to find the controlling navigationController of that page to push the new view into. Nothing seems to work that I have tried. IS this possible? Thanks
