And before you go off using NSOperationQueue, you should be aware
that
it's broken on Leopard, as described in this thread:
http://www.cocoabuilder.com/archive/message/cocoa/2008/10/30/221452
We already discuss this issues, and I agree with previous post that
said you misuse it:
http://www.cocoabuilder.com/archive/message/cocoa/2008/11/26/223819
I think NSOperationQueue should be used like this instead:
The process uses almost 200% of my Core 2 Duo proc and maybe i'm
wrong, but I do not managed to crash it.
#import <Foundation/Foundation.h>
@interface Tester : NSObject {
NSOperationQueue *_queue;
}
- (id)initWithQueue:(NSOperationQueue *)aQueue;
- (void)test;
@end
@implementation Tester
- (id)initWithQueue:(NSOperationQueue *)aQueue {
if((self = [super init])) {
_queue = [aQueue retain];
}
return self;
}
- (void)dealloc {
[_queue release];
[super dealloc];
}
- (void)test {
NSInvocationOperation *op = [[NSInvocationOperation alloc]
initWithTarget:self selector:_cmd
object:nil];
[_queue addOperation:op];
[op release];
}
@end
int main(int argc, char **argv)
{
[NSAutoreleasePool new];
NSMutableArray *testers = [NSMutableArray array];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
int i;
for(i = 0; i < 10; i++)
[testers addObject:[[[Tester alloc] initWithQueue:queue]
autorelease]];
for(Tester *tester in testers)
[tester test];
while(1) sleep(1000);
}
