If I invoke NSSound to play the same sound more than once, without
cycling through a run loop, it only plays the first time, and other
times, fails "silently". [1]
If I cycle through a run loop, then it works fine. [2]
The documentation states that NSSounds play in a separate thread and I
don't see any explanation for this in "Sound Programming Topics for
Cocoa". Is this a bug or is it too late for me to be trying to read?
Thanks,
Jerry
[1] Code that Doesn't Work -- "Tink" only plays once
int main(int argc, const char *argv[]) {
NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init] ;
NSSound* tink = [NSSound soundNamed:@"Tink"] ;
NSInteger j = 0 ;
while (j < 3) {
NSLog(@"tink") ;
[tink stop] ; // This line has no effect
[tink play] ;
usleep(2000000) ; // sleep 2 seconds
// Creating a new sound doesn't help either
[[NSSound soundNamed:@"Tink"] play] ;
usleep(2000000) ; // sleep 2 seconds
j++ ;
}
return 0 ;
}
[2] Code that works -- "Tink" plays repeatedly
@interface Player : NSObject {}
@end
@implementation Player
+ (void)playit {
[[NSSound soundNamed:@"Tink"] play] ;
}
@end
int main(int argc, const char *argv[]) {
NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init] ;
[NSTimer scheduledTimerWithTimeInterval:2.0
target:[Player class]
selector:@selector(playit)
userInfo:nil
repeats:YES] ;
[[NSRunLoop currentRunLoop] run] ;
return 0 ;
}
