The NSDictionary allKeys array is corrupted - not in the order they are in the dictionary?

in my project, I pull data from .plist, more specifically from NSDictionary. I am running a dictionary with .plist content that works well. When i do then

NSArray *array = [dict allKeys];

it fills the array with all the keys, but in a completely random order, different from the order that they are in the .plist file. I really need to save the order. Keys in the dictionary are arrays if this can cause a problem. What am I not getting?

Many thanks!

Just as there is no order between elements in an NSSet, there is no inherent order for key-value pairs in an NSDictionary.

NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:

You can create an NSArray with the dictionary keys in the order you want.

Try the following:

NSArray *array = [dict allKeys];

NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"self" ascending:NO];
NSArray *descriptors = [NSArray arrayWithObject:descriptor];

NSArray *orderedKeys = [array sortedArrayUsingDescriptors:descriptors];
