Hi,
thanks for your answer.
Have you checked the documentation:
<http://developer.apple.com/documentation/Cocoa/Conceptual/
Multithreading/articles/CocoaDetaching.html>
Search for "Configuring Your Run Loop"
that was exactly what I looked for. Now I call
[[NSRunLoop currentRunLoop] run];
and the Callback comes while the MainThread is sill busy.
But now I have a problem to end the RunLoop:
This is how i create the thread (in a small example):
- (IBAction)action:(id)sender
{
[NSThread detachNewThreadSelector:@selector(MyThreadRoutine:)
toTarget:self withObject:nil];
sleep(20);
NSLog(@"awaking");
}
If this is my thread routine, there is no problem. The runloop
returns immediately and the pool is released.
- (void) MyThreadRoutine:(id)anObject {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
[[NSRunLoop currentRunLoop] run];
[pool release];
NSLog(@"released pool");
}
When I use this thread routine, the thread executes the runloop. When
the frame is loaded I get the callback but then I want the runloop to
exit.
But this just doesn't happen. Does anyone know how to end the runloop
properly?
Or may it be that there is a bug?
The WebView seems to register with the RunLoop as an Input but on
release it doesn't deregister. How may I do this manually?
- (void) MyThreadRoutine:(id)anObject {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
WebView* wv = [LogWebView new];
[wv setFrameLoadDelegate:self];
[[wv mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL
URLWithString:@"http://www.google.de";]]];
[[NSRunLoop currentRunLoop] run];
[pool release];
NSLog(@"released pool");
}
- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame *)
frame {
NSLog(@"frame loaded");
[sender setFrameLoadDelegate:nil];
[sender release];
}
