Sort NSArray of custom objects based on sorting of another NSArray of strings
- by Nic Hubbard
I have two NSArray objects that I would like to be sorted the same. One contains NSString objects, the other custom Attribute objects. Here is what my "key" NSArray looks like:
// The master order
NSArray *stringOrder = [NSArray arrayWithObjects:@"12", @"10", @"2", nil];
The NSArray with custom objects:
// The array of custom Attribute objects that I want sorted by the stringOrder array
NSMutableArray *items = [[NSMutableArray alloc] init];
Attribute *attribute = nil;
attribute = [[Attribute alloc] init];
attribute.assetID = @"10";
[items addObject:attribute];
attribute = [[Attribute alloc] init];
attribute.assetID = @"12";
[items addObject:attribute];
attribute = [[Attribute alloc] init];
attribute.assetID = @"2";
[items addObject:attribute];
So, what I would like to do is use the stringOrder array to determine the sorting of the items array of custom objects.
How can I do this?
