在一定时间后使 NSThread 超时

发布于 2024-08-25 16:13:53 字数 362 浏览 9 评论 0原文

我有一个 NSThread，我想在一段时间后超时。

[NSThread detachNewThreadSelector:@selector(someFuntion) toTarget:self withObject:nil];

- (void) someFunction {
   //Some calculation that might take a long time.
   //if it takes more then 10 seconds i want it to end and display a error message
}

如果您能就此提供任何帮助，我们将不胜感激。

谢谢，

I have a NSThread that i would like to timeout after a certain amount of time.

[NSThread detachNewThreadSelector:@selector(someFuntion) toTarget:self withObject:nil];

- (void) someFunction {
   //Some calculation that might take a long time.
   //if it takes more then 10 seconds i want it to end and display a error message
}

Any help you can provide on this would be greatly appreciated.

不要使用 NSThread，而是使用 NSOperation。然后，您可以保留对该操作的引用，并将 NSTimer 设置为 10 秒。如果计时器触发，请告诉操作自行取消。

尝试这样的操作：

workerThread = [[NSThread alloc] initWithTarget:self selector:@selector(someFunction) object:nil];
[workerThread start];
timeoutTimer = [NSTimer scheduledTimerWithTimeInterval:10.0 target:workerThread selector:@selector(cancel) userInfo:nil repeats:NO];

确保 (1) 在线程完成时检查 workerThread.isCancelled 以查看线程是否超时，并且 (2) 调用 [timoutTimer invalidate] > 如果线程没有超时则清理计时器。

Try something like this:

workerThread = [[NSThread alloc] initWithTarget:self selector:@selector(someFunction) object:nil];
[workerThread start];
timeoutTimer = [NSTimer scheduledTimerWithTimeInterval:10.0 target:workerThread selector:@selector(cancel) userInfo:nil repeats:NO];

Be sure that you (1) check workerThread.isCancelled when the thread finishes to see whether the thread timed out, and (2) call [timoutTimer invalidate] to clean up the timer if the thread did not time out.
