How to return an NSMutableArray from an NSSet
Since -allObjects
returns an array, you can create a mutable version with:
NSMutableArray *array = [NSMutableArray arrayWithArray:[set allObjects]];
Or, alternatively, if you want to handle the object ownership:
NSMutableArray *array = [[set allObjects] mutableCopy];
I resolved crashing by using NSMutableArray's method 'addObjectsFromArray' to assign all NSSet objects to NSMutableArray like:
[mutableArray addObjectsFromArray:[cg_Schedule.schedule_Days allObjects]];
Hope this will helps you.
For an ordered set use:
NSArray *myArray = [[myOrderedSet array] mutableCopy];
