Answer by Harish Kumar Kailas for NSArray of weak references (__unsafe_unretained) to objects under ARC

To add weak self reference to NSMutableArray, create a custom class with a weak property as given below.

NSMutableArray *array = [NSMutableArray new];Step 1: create a custom class @interface DelegateRef : NSObject@property(nonatomic, weak)id delegateWeakReference;@endStep 2: create a method to add self as weak reference to NSMutableArray. But here we add the DelegateRef object-(void)addWeakRef:(id)ref{  DelegateRef *delRef = [DelegateRef new];  [delRef setDelegateWeakReference:ref]   [array addObject:delRef];}

Step 3: later on, if the property delegateWeakReference == nil, the object can be removed from the array

The property will be nil, and the references will be deallocated at proper time independent of this array references
