Hi, I'm building a game which will play a handfull of sounds all the time (rockets, rocket impacts etc). After a mere moment this turns into a real mess and i figured i need to limit the number of sounds. Problem is i don't want to decrease the number of channels of something because then one type of sound could "hog" the channels and ot...
So I've read some stuff about multithreading and NSOperation and wondering how I can use that to improve my app. Using Instruments I have isolated a few places where my app could definitely use a speed improvement. My question is, are these kinds of things suitable for another thread using NSOperation? Drawing a view: I have a rather co...

I'm still pretty new to programming so I have somewhat of a noob question. When you have an instance variable, in my case of type CLLocationManager, in my appDelegate.m file, I thought I could allocate and initialize my CLLocationManager instance variable in the applicationDidFinishLaunching method. And then I could use a button to sta...
I am subclassing NSURLConnection, and used MGTwitterEngine as a base to help me get started. That may be irrelevant. However, I noticed in their code they don't use @property or @synthesize for their ivars. They have wrapped the ivars in accessor methods which look like this: - (NSString *)identifier { return [[_identifier retain] aut...

...I am not sure which book to go with. I came to conclusion and it's between those two: [Programming in Objective-C 2.0] vs. [Learn Objective-C on the Mac]. My programming experience/skill is fairly strict, as I just know a little C. I know some loops (if, if-else, while, for, do, case) and how algorithm work. That's pretty much it, I...
I'm writing an Objective-C wrapper for a C library and having problems accessing the references of my ivars. The C library requires that I specify a function pointer that handles events, I specify it during the initialization of my Objective-C class. - (id) init { [super init]; RegisterClient( return self; } The C librar...

I have an application that will play a series of radio stations by choosing them from a drop down menu. Ideally I'd like to add some code, so that a spotlight search that would return any of the items in the dropdown and open the application as if you did this from within the application itself. The spotlight documentation gives no clue...
Hi, i am using the code below to implement a volume view into a cell. [[cell detailTextLabel] setText: @""]; MPVolumeView *systemVolumeSlider = [[MPVolumeView alloc] initWithFrame: CGRectMake(100, 10, 200, 100)]; [cell addSubview: systemVolumeSlider]; [self.view addSubview:cell]; [systemVolumeSlider release]; //[MPVolumeView r...
I have an application that iterates over an array every step and I seem to be getting surprisingly slow results when the array is empty. So, I investigated with some follow-up tests that went something like this: NSMutableArray* ar = [NSMutableArray array]; double time = CFAbsoluteTimeGetCurrent(); for (int i = 0; i < 10000; i++) { ...
I have a custom UIView which I named UIWheel that I am rotating upon TouchDown. This UIWheel has many UIViews which I would like to rotate at the opposite direction (so that they remain appearing upright even after rotation) . How do I code to tell it to get all of the UIViews in the UIWheel and in TouchDown rotate in the opposite direc...
