will the retained/strong class member variables got automatically clean'd up on unloading a view controller?

Question

I have the following property

.h

@property (nonatomic, strong) NSMutableDictionary *cache;

.m

@synthesize cache = _cach         


        

Answer 1

Regardless of whether you are using ARC or not, they will not be cleaned up in -viewDidUnload. You have to explicitly release them (or set them to nil under ARC.)
