Hi,
I have one Static Library called A.a which contains some categories. I am
referencing A.a into another library called B.a. I am using this B.a into
one Executable. In this case I am calling a method in B.a which calls the
category from A.a. Here it crashes with error unreference. Both A.a and
Hi,
I want to generate a unique string every time i push a button. Can I create
some string like that using a time stamp NSDate object may be.
ex. e3df44646ngfd5454nrteter
Its really useful to know about a small code segment or way to create a
unique string in iPhone.
Thank you and Kind Regards
Hi Tharindu-
In the past, I have used a UUID for this purpose. You could add the following
method to a category on NSString to make it quite easy:
+ (NSString*) stringWithNewUUID
{
CFUUIDRef uuidObj = CFUUIDCreate(nil);
NSString *newUUID = (NSString*)CFUUIDCreateString(nil, uuidObj);

As John P. said, I would going with a UUID. They are, by definition, what you
want.

Hi,
Thanks a lot. [[NSProcessInfo processInfo] globallyUniqueString] seems to be
the easiest one.
cool.
Thank you very much,

So long as it is ok for the string to be unique for the network the user is on
only. From the docs:
The ID includes the host name, process ID, and a time stamp, which ensures that
the ID is unique for the network.
A UUID (Universally Unique Identifier) is entirely unique.

UUID is the way to go. Here is a category I use to generate unique ids. It uses
core foundation to generate a 128-bit UUID and converts that to a 22-character
string. The conventional string form of a UUID is 36 characters long. A goal of
this code was to minimize the size of the id since my app
Hi,
When I noticed that IB has a control called "Image Editing" for the NSTextView,
I hope that this was going to be easy.
Later on I discovered, that I have to do more.
As I mentioned in my email, I have tried to set the property
>> -(void)setAllowsImageEditing:(BOOL)
but this did not help.
Is it just me, or is Xcode 3.2 missing the 2.2.1 version of the iPhone SDK?
Can that be remedied somehow? Or is Apple intentionally dropped support there?
-Patrick
P.S.
Is there a better list to be posting iPhone questions to?

With Icon Composer, you can have 5 separate images for the 5 icon sizes.
Cool. So I've got an icns file set up as my application icon, and I'd like
to use of the smaller "sub" icons in it for an NSAlert message. Problem is I
can't seem to figure out a way to do this. Anyone have any suggestions?

Yes, you cannot use UIButton's as keys in a dictionary, because keys in a
dictionary are copied, and buttons are not copyable.
Here's the better question: what are you trying to do? Using buttons as keys
in a dictionary seems... odd.
