Question

我创建了自己的NS行动子类,现在我想让其中的一些案例平行运行。因为这是一个同时同时进行的行动,所以我覆盖了它。

- (void)start {
    [self willChangeValueForKey:@"isExecuting"];
    isExecuting = YES;
    [self didChangeValueForKey:@"isExecuting"];

    error=NO;
    startedSection=NO;

    // start the task
    [task launch];
}

- (BOOL)isConcurrent {
    return YES;
}

- (BOOL)isExecuting {
    return isExecuting;
}

- (BOOL)isFinished {
    return isFinished;
}

当操作完成时执行下列代码:

[self willChangeValueForKey:@"isExecuting"];
[self willChangeValueForKey:@"isFinished"];
isExecuting = NO;
isFinished = YES;
[self didChangeValueForKey:@"isExecuting"];
[self didChangeValueForKey:@"isFinished"];

当我在将操作添加到 myQueue 之后添加 < my Queue wait all operations Arefinished> < my Queue wait all Offices Arefinished> 。当我删除 < my Quee wait all Operations All All All All All Operations All All All All All All All All All All Appers Applements Appried] < 之后添加 < /code> 。当我删除了 < my, < my quie wait all Oll All All All All Oust All Apperations All All All All All All Offed] < < < < < /code> < 之后, < unt it but a facts a fact is a ex a / / unse access a unt unt access access access access access a / unt / unt un

Answer 1

操作的货币如何执行? 我怀疑你再次将东西发送到主线上,你也会在 -wait Untill All Offices Arefinished 的主线中堵塞主线。这当然会陷入僵局。
