UIScrollView freezing NSTimer

[Terenn]

Hi everyone. I'm working on a simple beat generator, and here's a problem I really don't understand :

- I have 2 tracks. So I want to flip from one to an other using a UIScrollView, like flipping tabs in Safari. It works.

- I set a NSTimer to trigger the beat, for instance to play my sound every second. It works.


BUT ! When I try to slide between the tracks, my Timer is frozen during the scrolling transition. For a live performance instrument, it is very unconvenient. I've tried to put my NSTimer at different levels in my code, but the problem is always the same.


Anyone can help ?

Yes, it could work. Thanks for the link.

An other solution, without secondary thread, would be greatly appreciated thought.

Let me make it more clear. Don't read any of the posts on that thread except those by me. There are no secondary threads involved.

Thanks!!

Here is an example of code that worked for me :

PHP Code:

timer = [NSTimer scheduledTimerWithTimeInterval:interval target:target selector:callback userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:timer forMode:NSRunLoopCommonModes];
