使用NSTimer进行IOS位置更新

Question

我希望每秒只获取一次位置更新。这个间隔对于我想创建的动画来说非常重要，可以保持逼真的速度。我知道[myLocationManager startUpdatingLocation]将自动轮询“didUpdateToLocations”，但它不是每秒一次。

有没有办法使用NSTimer每秒获取一次我的位置？

谢谢 -jj

- (void)startUpdatingLocation
    self.locationManager = [CLLocationManager new];
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
    self.locationManager.delegate = self;
    [self.locationManager startUpdatingLocation];

    NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateLocation) userInfo:nil repeats:YES];
}

- (void)updateLocation {
    CLLocation location = self.locationManager.location;
    // do all the work here
}

#pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    // do nothing here
}
