Hi I would like to see if I can make a "search as you type" implementation, against a web service, that is optimized enough for it to run on an iPhone. The idea is that the user starts typing a word; "Foo", after each new letter I wait XXX ms. to see if they type another letter, if they don't, I call the web service using the word as a...
I have 2 threads in my application, a game update thread and render/IO/main thread. My update thread updates the game state, and the render thread renders the scene based on the updated values of the game state models and a few other variables stored inside an object (gameEngine). The render thread gets executed while the game thread is...
I an trying to put a method in a separate thread in the background. It nearly works except that occasionally I get a lot of error messages with the message METHODCLOSURE: OH NO SEPERATE THREAD with the bad spelling and all. Does anyone know what this means?

Hi all, In my application, I want to fetch new xml data after user scrolls through tableview and pulls the first cell down. As the data is loaded in tableview in chronological order, the updated data will be shown before the first cell.

My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview ...
Yesterday I read somewhere that NSTask isn't thread safe and that bothers me a lot, because I'm running a NSTask within a NSThread and is so far not experiencing any threading issues with it. My code is organized like this A: main thread -> B: worker thread -> C: worker task C: The worker task is a commandline program. B: The worker t...
Currently I'm using NSThread to cache images in another thread. [NSThread detachNewThreadSelector:@selector(cacheImage:) toTarget:self withObject:image]; Alternatively: [self performSelectorInBackground:@selector(cacheImage:) withObject:image]; Alternatively, I can use an NSOperationQueue NSInvocationOperation *invOperation = [[N...
Hello everyone, I am curious to know if you can loop an NSThread for the iphone sdk. I have learned that instead of using NSTimers which do run off of the main UI, I can use NSThreads to run actions in the background. Most of my NSTimers have the "repeats:" to YES, thus I need to know if NSThreads can be looped. Thanks Kevin ...
I'm still new to Objective C syntax, so I might be overcomplicating this, but I can't seem to figure out how to pass an NSTimeInterval to a thread.

I'm trying to use threading to load an image from a url. I have no background code and I'm having trouble getting the NSThread thing to work. What I've got is a UIimageView called photo1 and I've got an image that loads in from the net. (say http://www.google.com/logos/classicplus.png) but when navigating to the screen, the app pauses to...
Hello, I've got a lovely OpenGLES code slice that renders up images for me. When I want to, I can call a function on it: -(UIImage *)renderToImage; That does a lot of rendering work and returns me an image. This includes the generation of FBOs, textures, etc. Lately, I've found myself needing to enhance this. The image generation ta...
I have a function which executes as a different thread, thread named imageThread. But when the device rotates, the control automatically returns to the main thread and after their execution its given back to the imageThread. That's how i wanted it to function. But the problem is I am using some global variables, whose value changes in th...
