Hello, I want to play several audiofiles (*.wav) by touching the appropriate UImageViews. Each touching an UIImageView changes an "triggernumber" - wich view is selected. The audiofile names are stored in an array. But I can't figure out how to write a method to get the names and play the right sounds without using a select case method w...
Hello, I have some UIImageViews (Animals) and by touching them a specific soundloop starts to play. But if the user touches twice or more on the same View, the apropriate soundloop starts over and over again with an overlap.

I've looked on SO for examples of using Key Value Observing with an NSArray (or NSMutableArray) and apparently you need to use an NSArrayController (which unlike KVO I'm not familiar with), but I haven't found concrete examples of how to do this... can anyone explain with some sample code? For instance, if I have a GameModel which repre...

I'm fetching some objects out of a data store but the results aren't what I'm expecting. I'm new to CoreData but I'm fairly certain this should work. What am I missing? Note that User is a valid managed object and that I include its header file in this code, and that UserID is a valid property of that class. NSFetchRequest *request...

I'm working on a basic iPhone game that requires a single-screen tilemap. Nothing difficult there. I come from a C background, so my current solution looks a bit like this: typedef struct _Tile { NSString *type; } Tile; @interface Map { Tile mapData[MAP_TILE_MAX_X][MAP_TILE_MAX_Y]; } This works fine, but I'm wondering if ther...
My first instinct is to FooType *myFoo = nil; for (id obj in myArray) { if ( [obj isKindOfClass:[FooType class]] ) myFoo = obj; } With all the goodies in Objective-C and NSArray, there's gotta be a better way, right? ...
Hi everyone, I am trying to find if there is any object in the mutable array that matches with the object I pass. Please see the function below.
