ios – 引用块内的实例变量

@interface SomeObject : NSObject {
    UILabel *someLabel;
    dispatch_queue_t queue;
}
- (void)doAsyncStuff;
- (void)doAnimation;
@end

@implementation SomeObject

- (id)init {
    self = [super init];
    if (self) {
        someLabel = [[UILabel alloc] init];
        someLabel.text = @"Just inited";
        queue = dispatch_queue_create("com.me.myqueue",DISPATCH_QUEUE_SERIAL);
    }
    return self;
}

- (void)doAsyncStuff {
    dispatch_async(queue,^{
        ...
        // Do some stuff on the current thread,might take a while
        ...
        dispatch_async(dispatch_get_main_queue(),^{
            someLabel.text = [text stringByAppendingString:@" in block"];
            [self doAnimation];
        }
    }
}

- (void)doAnimation {
    ...
    // Does some animation in the UI
    ...
}

- (void)dealloc {
    if (queue) {
        dispatch_release(queue);
    }
    [someLabel release];
    [super dealloc];
}

如果我的块被启动,然后其他所有持有对该对象实例的引用的东西都会释放它,我保证不会调用dealloc,因为嵌套块引用了一个实例变量(和自己) – dealloc嵌套块退出后会发生什么？我的理解是我的街区有很强的自我参考,所以这应该是犹太人.
