Re: Asynchronous timers (without a run loop)

I've used both the CF and NS timer apis in many different situations without a hitch. They're fairly reliable. Perhaps you could explain your "can't use a runloop" restriction -- e.g. if you are writing a daemon or a kext, this is not the list you want to post to. You might find if you refa

You could call [self myThread:nil] after you start your timer. Joe K. On Dec 4, 2008, at 3:17 AM, Mahaboob wrote: Hi, I need to fire the thread repeatedly in regular time intervals. So I used the timer like: timer = [[NSTimer scheduledTimerWithTimeInterval:(double) [txtTimeinterval doub

Webview and streaming data

Dear all I am loading a web page that has a Quicktime streaming file. I was expecting to get the load delegate message "didFinishLoadForFrame" for the main frame when all the page is loaded and the movie starts playing, but the message is not called at that stage. Does anyone know how I c

Re: How To Deal With Rounding Errors

The way floats work the round will always be to the same number of bits no matter what the order of magnitude (ignoring the extreme values < 2^-1023 for doubles). Check that you haven't let any integers into you calculations. On 04/12/2008, at 7:08 PM, Bridger Maxwell wrote: Hey, Short ve

Re: Asynchronous timers (without a run loop)

NSRunLoop use to be based on the function select() (it was in GnuStep anyway), it waits for inputs but also has a single timeout value also, NSRunLoop works out how long the timeout value should be for the shortest NSTimer. If you want to wait on multiple timers without using run NSRunLoop
