后台运行核心位置的ipad应用程序崩溃

这件事我已经做了几天了。你知道这是什么意思吗？请帮忙！ 如果需要更多信息，请告诉我

EXC_坏_访问（SIGSEGV）

在其他帖子的帮助下，我找到了一个解决方案。结果是时间问题。我创建了另一个方法来重置我的位置管理器，并延迟调用它。这一切都解决了。希望这对你也有帮助

- (void)stopLocationManager
{
    if (locationManager)
    {
        [locationManager stopUpdatingLocation];
        [self performSelector:@selector(discardLocationManager) withObject:nil afterDelay:0.1];
    }
}

- (void) discardLocationManager
{
    locationManager.delegate = nil;
    locationManager = nil;

    if (self.isRestart == YES)
    {
        [self performSelector:@selector(startupLocationManager) withObject:nil afterDelay:0.1];
    }
}

你有没有发现这个问题？你能评论一下为什么需要延迟吗？你还可以分享你提到的其他帖子的链接吗？谢谢。你能分享一下这个错误的场景吗？我无法手动获取错误@小骗子

- (void)stopLocationManager
{
    if (locationManager)
    {
        [locationManager stopUpdatingLocation];
        [self performSelector:@selector(discardLocationManager) withObject:nil afterDelay:0.1];
    }
}

- (void) discardLocationManager
{
    locationManager.delegate = nil;
    locationManager = nil;

    if (self.isRestart == YES)
    {

    }
