Objective C Integration Problem

JRogoff

I am trying to add GeoSpark to a legacy Objective C application. I had some minor difficulties with adding the pod, which were resolved by adding an empty Swift file to my app.

After installing the pod and updating my permissions and capabilities I went to AppDelegate.m and added

#import <GeoSpark/GeoSpark.h> #import <GeoSpark/GeoSpark-Swift.h>
...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { ... [GeoSpark initialize:@"<my key>"]; ... }

However, even after cleaning and rebuilding my project, I continue to get Use of undeclared identifier 'GeoSpark' on the initialize line. According to Xcode, the only GeoSpark objects available are the version number and version string. Do I need to do something else since the pod is in Swift and my code is Objective C or did I miss a step somewhere?

Can you try to initialize with the below code:

[GeoSpark initialize:@"SDK-KEY" :@"" :@"" :@"" :@"" :AWSRegionUnknown];

Let us know if it works, else we will share sample example project in Objective C.

JRogoff

Same problem. I'm pretty sure it is a configuration problem as Xcode refuses to find the GeoSpark class despite the imports. I have tried changing the Packaging > Defines Module to Yes and playing with the Framework and Header Search Paths but neither has helped.

The simple answer would be if you did not declare the GeoSpark class public or add @objc in front of the declaration, but I assume you've done that, especially if you have a working objective c example.

JRogoff Yes, the methods are public & we declare @objc in front. Attached my example for your reference

Your example works right away (as it should) but mine refuses to build with the Geospark initialize line no matter what I try. I am going to try creating a brand new project with all the necessary pods and see how that goes.

JRogoff How did it go with a brand new project?

I finally got it to work in my existing project. That was ultimately a matter of getting the right combination of lines added to get Xcode to build everything but not ones that relied on it already being built. I thought I had tried all the permutations before posting my question here, but running through them again solved it.

It is similar enough to the Android app in most respects. It would help if the documentation clearly indicated which calls need to be on the main thread (the ones that create a locationManager) and which do not, but that seemed easy enough to work out.

I am having some trouble in Obj C where the app needs to know the user's current location at a moment in time (without tracking). This scenario works well in Android and it works fine if I use the CoreLocation libraries and implement CLLocationManagerDelegate. However, when I try to replace the CoreLocation stuff with GeoSpark using methods updateCurrentLocation or getCurrentLocation I never get a response either in the handler or from my GeoSparkDelegate didLocationUpdate method. Any suggestions?

Here is the example application for getting the current location. You can look into the code for your reference.

Nice Example. Thanks for sharing this information.
