[問題] 從 main thread perform 其他的 thread

[sinread (電腦真耗錢)]

小弟有一段code如下, 請各位先進給我一點意見:

- (void)RunVideoStream:(id)destView
{
        videoStream = [[myStream alloc] init];
        videoStream.channel = 0;

        xxx

        streamThread = [[NSThread alloc] initWithTarget:self selector:@selector(StreamStart) object:nil];
        [streamThread setName:@"stramOne"];
        [streamThread start];
}

- (void)StreamStart
{
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

        while(!exitNow)
        {
                [videoStream Connect];
        }

        [pool release];
}

xxx

- (void)SwitchCH:(id)objct
{
    NSLog(@"Got to change Channel : %d", [objct intValue]);
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
        NSNumber *nowCH = [NSNumber numberWithInt:row];

        [self performSelector:@selector(SwitchCH:) onThread:streamThread withObject:nowCH waitUntilDone:NO];
}

當UIPickerView被選取到某個row, 會變換 channel, 但是我目前這樣的寫法, 無法從

main thread 去 perform streamThread,

請問我該怎麼做才可以讓兩個thread 溝通?

→ zonble:NSPicker？這是什麼 Class？
→ sinread:UIPickerView 沒仔細去看原來的宣告XD 更正一下
