____的可见@interface没有声明选择器

Question

I have set up a method in a separate class (called ExternalClass) that needs to take two arguments.

-(void) openImage:(NSDictionary *)payload InApp:(UIApplication *)app;

In my AppDelegate.m, I call the method like this:

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)payload fetchCompletionHandler (void (^)(UIBackgroundFetchResult))completionHandler
    {
        [[ExternalClass sharedInstance] openImage:payload InApp:application];
    }

I am getting "No visible @interface for ExternalClass declares the selector 'openImage:InApp'

Any idea why?

Answer 1

I think you forgot to declare this method in header(.h) file.

Declare this method in ExternalClass.h file.

-(void) openImage:(NSDictionary *)payload InApp:(UIApplication *)app;

And import this ExternalClass.h , where you want to use this method.

Okay, I'm trying to create a framework and use it in my app. It turns out none of the changes I made to any my framework methods were being reflected in my app. Thank you guys for pointing me in the right direction.
