throwing an exception in objective-c/cocoa

Question

What\'s the best way to throw an exception in objective-c/cocoa?

Answer 1

@throw([NSException exceptionWith…])

Xcode recognizes @throw statements as function exit points, like return statements. Using the @throw syntax avoids erroneous "Control may reach end of non-void function" warnings that you may get from [NSException raise:…].

Also, @throw can be used to throw objects that are not of class NSException.
