A quick one: Passing a reference/pointer to NSString
Hi Guys
What do I need to do in the following code to get theString to take the value
I'm giving it in foo i.e. Hi there?
- (void) aMethod
{
NSString* theString = @;
[self foo:theString];
}
- (NSString*) foo:(NSString*)aString
{
NSString* stringB = @Hi there;
aString = stringB;
}
Thanks guys.

Re: A quick one: Passing a reference/pointer to NSString
Sorry - it should have been:
- (void) aMethod
{
NSString* string1 = @;
NSString* string2 = @;
string1 = [self foo:string2];
}
- (NSString*) foo:(NSString*)aString
{
NSString* stringA = @Hi there;
NSString* stringB = @Everyone;
aString = stringB;
return stringA;
}
I need to get 2 strings back from foo. I can get foo to return one. I need to
pass the other one in by reference. It seems that since I'm passing a pointer
to an NSString as the argument, it should be fine but it's not.
By the way

Re: Questions about Core Data and SQLite
Thanks guys for all this info. Also can anyone point me to a good book or website where I can learn about and how to incorporate Core Data into my existing Cocoa App. I've found mac documentation isn't the easiest to learn from.

Re: Hillegass, Third Edition, Chapter 18
Hi Jon Just an aside - does Hillegass, Third Edition teach you Core Data? The blurb on Amazon says it does but when I looked at the index online it didn't mention Core Data.

Questions about Core Data and SQLite
Hi Guys I've got a cocoa app that is installed as a client on several machines and uses MySql as the database. Is there any way I can incorporate Core Data into the app so that I can do away with using MySql? i.e. log into the app on one machine (using it's SQLite database) from the same app on a different machine? If so, given that I know a some about Cocoa development but nothing about using Core Data, can anyone direct me to some good documentation that explains how to incorporate Core Data into an already existing Cocoa app. (It currently uses MySQL). Thanks greatly for any help.

Re: Stopping actions mid stream
Thanks everyone. I ended up just disabling the option in the end. Cheers Jeff Thanks Andy and Jean-Daniel.

Stopping actions mid stream
Hi Guys I've set up matrix with 2 radio buttons (1 and 2) with a delegate method that gets run when the matrix gets clicked. Lets say radio button 1 is highlighted and someone clicks on radio button 2. The delegate method has some code that checks whether the radio buttons are allowed to be changed from 1 to 2 and if not, sends an alert to the user. My problem is how can I stop the radio buttons themselves changing from 1 to 2. When programming in Visual Basic there was a method that stopped the action from completing. Is there something similar I can do here or some other way. Thanks in advance.
