Dear Keith and all,
I hope my iPad could communicate with my servers. The servers run Java.
However, I don't want to use Web services. So I hope I could use BSD sockets
to talk with remote Java servers. I think XML should be utilized too for
this case.
I am not sure if it is possible to do that.

I'm a developer of Gitbox - a git repository manager. It keeps several repos

modal dialog pops up.

Normally, user will see only one sheet at a time. There won't be any sort of

Hi,
I have an array of dictionaries.
One dictionary-entry looks like this:
{
ID = 34;
counter = 2;
date = 2011-04-19 15:43:52 +0200;
title = test.pdf;
type = file;
}
Now I would like to sort my array of dictionaries first by type and then
(within the type-dictionaries) by
In that array of sort descriptors, you'd need to pass two of them. The first to
sort by type and the second to sort by date. The second sort descriptor would
only be used if two objects are sorted as equal by the first descriptor.

Either of these would allow you to do what you want for NSArray:
- (NSArray *)sortedArrayUsingComparator:(NSComparator)cmptr;
- (NSArray *)sortedArrayUsingFunction:(NSInteger (*)(id, id, void *))comparator
context:(void *)context;
And these for NSMutableArray:

(so use two sorting-criteria with a different priority)

The one subtle complication here is that NSStream does not currently
support remote connections on iOS without modification. Fortunately,
Apple provides documentation on how to get around this with a minimal
amount of CFNetwork to setup the stream:
