Get directory contents in date modified order

nall’s code above pointed me in the right direction, but I think there are some mistakes in the code as posted above. For instance:

1. Why is filesAndProperties allocated using NMutableDictonary rather than an NSMutableArray?

2. 
   NSDictionary* properties = [[NSFileManager defaultManager]
                                           attributesOfItemAtPath:NSFileModificationDate
                                           error:&error];
   
   

   The code above is passing the wrong parameter for attributesOfItemAtPath – it should be attributesOfItemAtPath:path

3. Your are sorting the files array, but you should be sorting filesAndProperties.

I have implemented the same, with corrections, and using blocks and posted below:

    NSArray *searchPaths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* documentsPath = [searchPaths objectAtIndex: 0]; 

    NSError* error = nil;
    NSArray* filesArray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsPath error:&error];
    if(error != nil) {
        NSLog(@"Error in reading files: %@", [error localizedDescription]);
        return;
    }

    // sort by creation date
    NSMutableArray* filesAndProperties = [NSMutableArray arrayWithCapacity:[filesArray count]];
    for(NSString* file in filesArray) {
        NSString* filePath = [iMgr.documentsPath stringByAppendingPathComponent:file];
        NSDictionary* properties = [[NSFileManager defaultManager]
                                    attributesOfItemAtPath:filePath
                                    error:&error];
        NSDate* modDate = [properties objectForKey:NSFileModificationDate];

        if(error == nil)
        {
            [filesAndProperties addObject:[NSDictionary dictionaryWithObjectsAndKeys:
                                           file, @"path",
                                           modDate, @"lastModDate",
                                           nil]];                 
        }
    }

        // sort using a block
        // order inverted as we want latest date first
    NSArray* sortedFiles = [filesAndProperties sortedArrayUsingComparator:
                            ^(id path1, id path2)
                            {                               
                                // compare 
                                NSComparisonResult comp = [[path1 objectForKey:@"lastModDate"] compare:
                                                           [path2 objectForKey:@"lastModDate"]];
                                // invert ordering
                                if (comp == NSOrderedDescending) {
                                    comp = NSOrderedAscending;
                                }
                                else if(comp == NSOrderedAscending){
                                    comp = NSOrderedDescending;
                                }
                                return comp;                                
                            }];
