Hey, Is anyone aware of a way to receive NSURLDownload's delegate methods on a separate thread, i.e. not the main one? I am using an NSOperationQueue to manage them but at the moment I need to use the performSelectorOnMainThread method to get it too work. The problem with this is that it drives the kernel task crazy reaching about 30% o...
If I detach an NSThread will Cocoa run it in a separate memory heap or memory zone? For example, if I were to detach a thread, use malloc to create a large buffer, and then let the thread exit, would I get that memory back in some kind of automatic thread cleanup, or would it be leaked? What about if I used a POSIX thread (pthread) inst...
I have a NSDictionary that is passed from the main thread to a second thread which retains, uses, then releases the variable. What if the main thread autorelease pool is drained while the 2nd thread is still using the variable? Even though I have retained the variable in the 2nd thread, will the main thread's pool know that its still be...
I have a worker thread that I want to do one bit of its task, then pause & wait for the "ok, continue" command from another thread, then pause & wait, etc. The use case is: the controlling object is a view that I want to display information about what's going on inside the worker-thread, and allow me to "single-step" through the worker ...
I'm in the midst of debugging an extremely unusual problem, and I was wondering if anybody might have any insight into what might be going wrong: In a controller class from a NIB, I take an NSPanel from that same NIB, and then show it app modally on an NSWindow (that was created by hand in code): [[NSApplication sharedApplication] begi...

For example ( to specify my need ) - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { // 1. response - schedule myThread // 2. response - schedule a new thread which will be executed after myThread // 3. response - s...

I'm having a problem when trying to add a UITabBar as a subview of my AppDelegate's window. The link above shows a screenshot of the messy state of the screen. TabBarInAMessyState.png The results are unpredictable. In this picture only the UITabBarItem's titles were affected, but sometimes the TabBar background is not shown (consequent...
I am developing a RSS reader which uses a NSMutableArray (_stories) to store the contents of the RSS Feed. This array is being used by two different threads in the application and may be accessed simultaneously in two occasions, since: It is the data-source of the UITableViewController (which reads it's content and shows the desired in...
Hi Im using a large amount of very small web services in my app and I have been down a couple of roads that does not scale or work as desired. The Design approach Im thinking about: The task for the viewController is to ask for a set of data from a general webServicesClass, this task is started in a new NSThread -> this will instantiat...

I have an iPhone app, where I'm displaying a tableview, that's loaded from an RSS feed. When the view is loaded, I call this method to run in a new NSThread: - (void)start:(NSURL*)url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSXMLParser *XMLParser = [[[NSXMLParser alloc] initWithContentsOfURL:url] autorelease]; [...
I have such a code: [self performSelectorInBackground:@selector(indicator) withObject:nil]; [self mail]; //opening my controller of e-mail sending - (void)indicator { [actView startAnimating]; } This works fine, but i'm afraid of thread safety. I'm not allocating memory in a second thread, but smth tell's me that's too simple:) ...
I'm trying to use NSAssert throughout my iPhone app so that if an unexpected condition occurs, the application fails-fast and crashes with a meaningful message in the crash log. This works fine if the failing NSAssert is on the main thread, as it raises NSInternalInconsistencyException by default which is uncaught and stops execution. B...
My main program spawns a thread, which executes the following: // alloc autorelease pool somewhere before NSArray *blah = [NSArray arrayWithObject: @"moo"]; [self performSelectorOnMainThread: @selector(boonk:) withObject: blah waitUntilDone: NO]; // release autorelease pool somewhere after Now, this seems buggy to me because the...
Hi everyone, I am writing an application which has to communicate with a device connected via USB. The app sends and receives data in turns from the device on a fixed timing. All Rx/Tx happens in a separate thread because otherwise the UI would be blocked. The basic structure looks basically like this. (autorelease pools and stuff omitt...
