CGAffineTransform from NSString

How can I obtain a CGAffineTransform from a NSString in Cocoa?

On iOS there is CGAffineTransformFromString.

For lack of a better solution I'm currently doing this:

CGAffineTransform CGAffineTransformFromString(NSString *string)
{
    string = [string stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"[ ]"]];
    NSArray *components = [string componentsSeparatedByString:@","];
    CGAffineTransform transform;
    transform.a = [[components objectAtIndex:0] floatValue];
    transform.b = [[components objectAtIndex:1] floatValue];
    transform.c = [[components objectAtIndex:2] floatValue];
    transform.d = [[components objectAtIndex:3] floatValue];
    transform.tx = [[components objectAtIndex:4] floatValue];
    transform.ty = [[components objectAtIndex:5] floatValue];
    return transform;
}
