I'm able to put the contents of an NSSet
into an NSMutableArray
like this:
NSMutableArray *array = [set allObjects];
The compiler complains though because [set allObjects] returns an NSArray
not an NSMutableArray
. How should this be fixed?
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];
