Hi,
Please look at the following situations:
1. Created a mutable array in main thread, can I read its values in a secondary thread safely, while no other thread is modifying this mutable array?
2. I need to add objects to this mutable array from a secondary thread, and no other thread is modifying it. Can I simply add an object like, [array addObject:obj]; or if this is wrong how to achieve the same? The object to add is mostly NSString or NSNumber or a mutable dictionary of NSString and NSNumber.
Please help.
Best,
Nick
