Core code
MLModel* model = nil;
NSError *error = nil;
@try
{
model = [MLModel modelWithContentsOfURL:modelURL error:&error];
}
@catch (NSException *exception)
{
model = nil;
return Ret_OperationErr_InvalidInit;
}
Two question:
- What does this stack mean?
- I added @ try @ catch, why is it still crashing?
