Question

I am stuck here……
I have two arrays Arr_title and Arr_distance
I get sorted Arr_distance using this method

NSSortDescriptor *sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"self" ascending:YES]autorelease];

sortedFloats = [appDel.Arr_distance sortedArrayUsingDescriptors:
                             [NSArray arrayWithObject:sortDescriptor]];

but problem is that i want to sort Arr_title according to index of sortedFloats array…

thx in advance for help me……….

Answer 1

Try this,

NSDictionary *dict = [NSDictionary dictionaryWithObjects:Arr_title forKeys:Arr_distance];

NSSortDescriptor *sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"self" ascending:YES] autorelease];
sortedFloats = [appDel.Arr_distance sortedArrayUsingDescriptors:
                         [NSArray arrayWithObject:sortDescriptor]];


NSMutableArray *sortedTitles = [NSMutableArray array];

for (NSString *key in sortedFloats) {//or just use sortedTitles = [dict objectsForKeys:sortedFloats notFoundMarker:[NSNull null]];
    [sortedTitles addObject:[dict valueForKey:key]]; 
}

NSLog(@"%@",sortedValues);

sortedTitles should give you the array sorted in the same order as sortedFloats.
