App crashes attempting to remove annotation from click event
Brianggalvez opened this issue · comments
In my app I want to remove an annotation after a user clicks on it. What I do is pass the annotation param of the event to the mapView removeAnnotation method and the the app crashes with the following stack trace:

It seems like a null-pointer in the didTapMarker: selector. It would probably already help if you add some NULL_IF_NIL() macros around the optional values.
mmm but the click event fires without problems. The error appears when I perform a removeAnnotation using as a parameter the annotation that the click event returns
Mhh okay, then the stack does not help much I think
I'm doing something somewhat similar. Keep a reference to all your Annotations, and delete that (you can use userObject.uuid as reference).

I've tried this workaround but only works for the first annotation. After that, any annotation gets removed
Is it possible to send me a small snippet of your map click event that removes the annotation?
I've just recently implemented something similar and it works fine for the first all all other annotations.
sorry guys, issue on my end. Even though, I've to implement the workaround of having an array of annotations because using the annotation param from click event caused the crash described in the original issue
