    _locationManager=[[CLLocationManager alloc] init];
    _locationManager.delegate=self;
    _locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    _locationManager.distanceFilter=10;
    if ([[UIDevice currentDevice].systemVersion intValue]>=8) {
        [_locationManager requestWhenInUseAuthorization];//使用程序其间允许访问位置数据（iOS8定位需要）
    }
    [_locationManager startUpdatingLocation];//开启定位
}else {
    //提示用户无法进行定位操作
    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"提示" message:@"定位失败,请确认开启定位..." delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
