我在其他帖子的帮助下找到了解决方案。事实证明这是一个时间问题。我创建了另一种方法来重置我的位置管理器，我会延迟调用它。这解决了一切。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];
    }
}
