使用Apportable将iOS应用转换为Android-构建时出现各种参考和定义错误

Question

I am trying to convert an iOS app using Apportable .

Unfortunately i am facing some errors when building using the command apportable build . I have tried to Google and search on StackOverflow for solutions on the problem. Found out that adding "add_params" in the configuration.json could help but that doesn't work and i don't exactly know what to add there. The build output:

Packaging resources.

I still have problems with MKPointAnnotation , MKUserLocation and MKPinAnnotationView . They are used in the following class:

ChooseShoppingLocationViewController.h

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#import "NotificationController.h"

@interface ChooseShoppingLocationViewController : UIViewController <MKMapViewDelegate>
@property (strong, nonatomic) CLLocation *shoppingLocation;
@end

ChooseShoppingLocationViewController.m

@interface ChooseShoppingLocationViewController ()
@property (strong, nonatomic) IBOutlet MKMapView *mapView;
@property (strong, nonatomic) MKPointAnnotation *shoppingLocationAnnotation;
@end

...

- (MKPointAnnotation *)getNewShoppingLocationAnnotation
{
    MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
    annotation.title = YOUR_SHOPPING_AREA_TEXT;
    return annotation;
}

...

- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
    userLocation.title = @"";
    CLLocationCoordinate2D location = [userLocation coordinate];
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(location, DISTANCE_SPAN, DISTANCE_SPAN);

    if (self.isFirstUserLocation) {
        dispatch_queue_t animateQueue = dispatch_queue_create("show user location", NULL);
        dispatch_async(animateQueue, ^{
            sleep(1.0);
            dispatch_async(dispatch_get_main_queue(), ^{
                [self.mapView setRegion:region animated:YES];
                [self.mapView selectAnnotation:self.shoppingLocationAnnotation animated:YES];
            });
        });
        self.isFirstUserLocation = NO;
    }
}

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id < MKAnnotation >)annotation {
    if ([annotation isKindOfClass:[MKUserLocation class]]) {
        return nil;
    }

    MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"DETAILPIN_ID"];
    [pinView setAnimatesDrop:YES];
    [pinView setCanShowCallout:YES];
    [pinView setSelected:YES];
    return pinView;
}

Is it now allowed to use these classes with Apportable ?

Btw if i try to remove the use of these classes i am still getting the error:

scons: *** [assets/ResourceRules.plist] Source `/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/ResourceRules.plist' not found, needed by target `assets/ResourceRules.plist'.

Answer 1

The duplicate symbol errors indicate that StoreViewAnnotation is defined both in StoreViewAnnotation.m and main.m. Does main.m import StoreViewAnnotation.m instead of StoreViewAnnotation.h?

The ChooseShoppingLocationViewController.m errors look like a missing symbol in the app.

The error about _UIRefreshControl is because UIRefreshControl is not yet implemented in the Apportable platform. For now, you'll need to stub around it.
