Objective-C iVar Declarations

Hello Community,

I've been looking at different ways to declare ivars in Objective-C and I've come across one that looks like the following:

// TestClass.m

@interface TestClass
// ivars here
@end

@implementation TestClass {
   // ivars here
}
@end

What exactly is the difference between declaring your ivars in the implementation file interface compared to declaring it in your implementation?

Cheers,

Xing (Richard) Lu
