Nick,
In your secondary you can use dispatch_async or dispatch_sync to schedule a
block of code to execute on the main thread. Below is a simple example:
dispatch_async(dispatch_get_main_queue(), ^{
// put your code to modify mutable array here
});
I hope this helps.
Thanks,
Abdul

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
