Answer 1

使用氯乙烯只有在发射时才能看到发射地点警戒线。

Answer 2

使用氯乙烯拥有代表的经理前往该地点。如果失误,则检查错误代码,看看用户是否拒绝在附录中提供地点:

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {

    UIAlertView *alert;
    //denied?
    if(error.code == kCLErrorDenied) alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error",@"Error title header") message:NSLocalizedString(@"Turn on Location Services in Settings to use your location",@"Turn on Location Services in Settings to use your location") delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    else alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Error",@"Error title header") message:NSLocalizedString(@"At the moment it is not possible to retreive your location",@"At the moment it is not possible to retreive your location") delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
}
