No.

The SDK target only controls which version of the libraries are linked at compile time. If you try and make a call to a 10.5-only library on 10.4 you'll most likely crash. Read the cross development docs (previously linked) if you're still confused, they are very clear in my opinion.

I am also confused with that.
Using project settings that above mentioned can we use MAC OS 10.5 SDK under
10.4 ?
and if so, i am using CalCalendarStore framework that is available from
10.5. will that application work in MAC OS 10.4 ?
if i compile, with Active SDK 10.4 it will give me some errors.
same issue with property and synthesize.

So, will this run successfully under MAC OS 10.4 and 10.5 ?


Thanks.

Thanks.

@ Shawn Erickson

(small nit on terminology... you don't run under an SDK)

Yes* but only if you specify the (min) target OS as 10.4 and SDK as 10.5.

Oh, ok. I'll take a look to docmentation (which is sooooooo extensive...)

Humm cannot find the doc I recall but the following outlines a way to
do what I think you are asking (note NSClassFromString())...

Don't worry. I'll also read this.

Thank you!
