Question

What would be the mutable varient of this line of code:

self.dsSearch = [self.ds filteredArrayUsingPredicate:resultPredicate];

Any help appreciated:)

Answer 1

[NSArray filteredArrayUsingPredicate] returns an NSArray so to make it into an NSMutableArray use:

self.dsSearch = [[NSMutableArray alloc] initWithArray:[self.ds filteredArrayUsingPredicate:resultPredicate]];

Or if you want an auto-released object, use:

self.dsSearch = [NSMutableArray arrayWithArray:[self.ds filteredArrayUsingPredicate:resultPredicate]];
