Hi I am building an augmented reality iOS app with the Metaio SDK, and am running into some issues with the function getAllGeometriesFromViewportCoordinates. In my header (.h file), I'm calling the class constructor:
#interface HelloWorldViewController : MetaioSDKViewController
{
metaio::Vector3d modelLocation;
}
and in my .mm file:
modelLocation = m_metaioSDK->getAllGeometriesFromViewportCoordinates(loc.x, loc.y, true, 3, 0);
The error I'm getting is "No viable overloaded '='"
Here's what the Metaio docs say about this function: http://doxygen.metaio.com/metaioSDK55/getAllGeometriesFromViewportCoordinates_1a31f4d68ef273dc05d8be5094dc25910d.html
Any help would be appreciated. Thanks, Steve
The return type of getAllGeometriesFromViewportCoordinates is
stlcompat::Vector < metaio::GeometryHit >
You're trying to assign it to a metaio::Vector3d.
Maybe you actually want to call this method? http://doxygen.metaio.com/metaioSDK55/get3DPositionFromScreenCoordinates_1ae31b85a5c22fd3392ef6186401fd6046.html

To set up Receipt-Validation in my iOS app, I am now following this tutorial:
https://www.raywenderlich.com/9257-in-app-purchases-receipt-validation-tutorial
and reading at this point: Loading the Receipt.
While reading and attempting to understand what is going on I also try to integrate the code in my own app, by doing so getting a hands-on understanding of the process.
Here is one problem I am hitting at this moment:
On this line of code:
private func loadReceipt() -> UnsafeMutablePointer<PKCS7>? {
I get this error message:
Use of undeclared type 'PKCS7'
After searching the net and trying a few things, I guess it is related to the use of the use of the ReceiptVerifier-Bridging-Header.h file. But I am not sure how to set it in the project.
I will be glad if anyone has some tip allowing me to move forward.
Thanks in advance!
In case this can be useful, here is the meaningful contents of the bridging header file (ReceiptVerifier-Bridging-Header.h):
#import <openssl/pkcs7.h>
#import <openssl/objects.h>
#import <openssl/evp.h>
#import <openssl/ssl.h>
#import <openssl/asn1_locl.h>
The problem is that I had simply copied the bridge-header file, without doing the proper setting as explained here:

I'm trying to bind a native Objective-C SDK to my Xamarin project. I follow this tutoriel : Walkthrough: Binding an iOS Objective-C Library
Everything work till : Using Objective Sharpie. I generated the ApiDefinition and Strucs files but in my ApiDefinition, some class needs protocols.
// #interface BIOEvent : NSObject <BIODiagnosticEvent>
[BaseType(typeof(NSObject))]
interface BIOEvent : IBIODiagnosticEvent
{
// -(instancetype _Nonnull)initWithType:(BIOEventType)type;
[Export("initWithType:")]
IntPtr Constructor(BIOEventType type);
}
For example here, the file doesn't found "IBIODiagnosticEvent". I have the impression that Sharpie didn't bind some headers files. Files which are #protocol
Could you help me please ?
Thanks.
Ok, for those who have the same error. Xamarin add "I" convention before the name of the protocol. Just remove it.
I am tinkering with the sample project "SpatialAudio" from Google VR SDK for Unity, to implement it in iOS.
I built it in Unity using the latest GVR SDK, so I had to replace a few deprecated keywords (GvrAudioSource instead of CardboardAudioSource, etc.)
If I build it in Xcode just as Unity gives it to me, it runs fine in the physical device.
Then, I tried to edit the Unity-generated file 'main.mm' to change the default App Controller (UnityAppController) to a new one, let's call it NewAppController.
// main.mm
...
const char* AppControllerClassName = "UnityAppController";
...
//UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]); // old
UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:"NewAppController"]); // new
NewAppController is a class which inherits from UnityAppController and does not override any of its methods or properties, like this:
#interface NewAppController : UnityAppController
#end
#implementation NewAppController
#end
I thought that it should work exactly the same as before, but now I get the following warning in runtime:
"Audio effect GVR Audio Renderer could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly."
Everything else works just fine: I can see the video and even hear the sounds, but only they are not 'spatialized'.
I am using:
GVR SDK 1.1,
Unity 5.5.0f3,
iOS 10.1.1
I found the solution. I was missing two important things: First, messing with main.mm causes a lot of trouble. The correct approach for defining a custom App Controller is to create a subclass of UnityAppController and adding the macro IMPL_APP_CONTROLLER_SUBCLASS(name_of_the_class) at the bottom of its .mm file. Second, Unity automatically generates a custom app controller, called CardboardAppController, which is located in the build directory, under 'Libraries/Plugins/iOS'. One of its functions is registering the unity audio effect plugin. I was bypassing this file without knowing, causing the audio renderer to not initialize properly. So my solution was to comment out the macro at the end of the file CardboardAppController.mm (line 71):
//IMPL_APP_CONTROLLER_SUBCLASS(CardboardAppController)
And defining the new custom controller as a subclass of CardboardAppController:
#import "CardboardAppController.h"
#interface NewAppController : CardboardAppController
#end
#implementation NewAppController
#end
IMPL_APP_CONTROLLER_SUBCLASS(NewAppController)
I need to call methods in the custom view in iOS module from titanium project. I have followed the tutorials in Appcelarator documentation about creating iOS module. I could create the custom view in Titanium using below code.
var manage = require('com.test');
var manageView = manage.createView({
left:40,
right:40,
top:40,
height: 250,
backgroundColor:'blue' }); manageView.customMethodInView();
But i got error like "customMethodInView is not a function" when i run the app.
#import "TiViewProxy.h"
#import "CustomView.h"
#interface ComTestViewProxy : TiViewProxy {
CustomView *customView;
}
- (void) customMethodInView;
#end
This is the code in viewProxy class in iOS Module project.
Please help.
I know this is late, but for any wondering soul out there, it is my understanding that even if you don't intend to pass an argument for your method, the signature of the method in the native module should always take one:
your method
- (void) customMethodInView;
should look like this :
- (void)customMethodInView:(id)unused;
I am trying to use the BoxSearchRequestBuilder class to be able to perform a search in Box via the iOS SDK (v2). When I try to instantiate a BoxSearchRequestBuilder instance with its initializer, I get a compiler error.
What I am trying to do:
BoxSearchRequestBuilder* builder = [[BoxSearchRequestBuilder alloc] initWithSearch:#"123" queryStringParameters:#{#"content_types" : #"tags"}];
The error:
receiver 'BoxSearchRequestBuilder' for class message is a forward declaration or
receiver type 'BoxSearchRequestBuilder' for instance message is a forward declaration.
Basically the BoxSearchRequestBuilder class is declared via a forward declaration (#BoxSearchRequestBuilder), so I cannot directly access its properties/initializers.
I can fix the error by going to the iOS SDK class BoxSearchResourceManager and changing the forward declaration to an import statement:
#import "BoxSearchRequestBuilder.h"
//#class BoxSearchRequestBuilder;
However, I don't think I should be doing this. Are there any other alternatives? The rest of the API works fine.
Thanks for flagging this.
It has been fixed thanks to your feedback in this change:
