Automatic Reference Counting Issue: Passing address of non-local object to __autoreleasing parameter for write-back

Question

I\'m trying to pass pointer to pointer to a method, but apparently ARC has some issues with how I\'m doing it. Here the two methods:

+ (NSString *)personProp         


        

Answer 1

The __strong storage qualifier is needed for this case.

+ (void)SHL_initPersonPropertyNamesWithArray:(NSArray * __strong *)theArray

However, this code doesn't follow the Basic Memory Management Rules.

You own any object you create

You create an object using a method whose name begins with “alloc”, “new”, “copy”, or “mutableCopy” (for example, alloc, newObject, or mutableCopy).

For what reason do you want to do this?
