Question

使用Xcode编写应用程序使用＆＃34;获取当前位置＆＃34;方法。获得Parse issue, Expected ';' after method prototype但是当我添加它时，我会继续获得更多错误，所以我假设只是那个错误。我也收到两个语义问题，缺少方法声明的上下文。解析问题在该部分的第1行，语义问题出现在第11和第20行。任何帮助将不胜感激。提前谢谢。

- (IBAction)getCurrentLocation:(id)sender {
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation]; 
}

@end

pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager
        didFailWithError:(NSError *)error {
    NSLog(@"didFailWithError: %@", error);
    UIAlertView *errorAlert = [[UIAlertView alloc]
                               initWithTitle:@"Error"
                               message:@"Failed to Get Your Location"
                               delegate:nil cancelButtonTitle:@"OK"
                               otherButtonTitles:nil];
    [errorAlert show]; 
}

- (void)locationManager:(CLLocationManager *)manager
        didUpdateToLocation:(CLLocation *)newLocation 
        fromLocation:(CLLocation *)oldLocation {
    NSLog(@"didUpdateToLocation: %@", newLocation);
    CLLocation *currentLocation = newLocation;

    if (currentLocation != nil) {
        longitudeLabel.text = [NSString stringWithFormat:@"%.8f",
                                        currentLocation.coordinate.longitude];
        latitudeLabel.text = [NSString stringWithFormat:@"%.8f",
                                       currentLocation.coordinate.latitude];
    } 
}

xcode不是智能调试器/编译器所以当你得到一个愚蠢的错误时，它可能不是来自它的地方:) 在这种情况下，我认为你错过了＃34;＃＆＃34;签署＆＃34; pragma mark＆＃34; 这就是为什么Xcode不断给出错误和警告:) 希望它有所帮助

这方面有什么问题？获得2个语义和1个解析问题
