Hai,
I'm building my first app in cocoa (first app in a real programming
language), and i stumbled into a few problems..
I'm trying to figure out the exception handling in cocoa.
First of all the purpose: i've found somewhere some code to talk to
mysql. This is (if i correctly understood c) and i'm building a little
wrapper around it, so i can talk with the c-framework(libmysqlclient.a)
with objective-C calls.
Here my problem. I looked at the code and i noticed the framework always
returns a pointer (itself i presume) and NULL if there's an error. After
that you can call a function for the description of that error. I could
do the same with my wrapper (that is: return nil). But isn't there a
better way to send and capture errors...
I did a bit of coding in .Net, c# and there were those nice statements
as:
try{
// do something here
}catch(Exception e){
console.write(e.ToString());
}
If i'm correct a kind like Java....
Is there something like this in cocoa.
I would be glad with some pointers and help about handling errors...
Jasper.
