(NSDictionary *) labelAttrs = 0x00000001

While doing some debugging, I printed out the description of the NSDictionary variable, which gives the following:

(NSDictionary *) labelAttrs = 0x00000001

Can someone clarify why this is 1?

I would understand nilor an object pointer, but why 1?

UPDATE

The code:

NSDictionary *labelAttrs = @{NSForegroundColorAttributeName:[UIColor darkGrayColor]};

Crash on launch on iOS5, but not iOS6, but this:

Are new object literals backward compatible with iOS 5?

it looks like you can use new literals with iOS5 (as long as you create against iOS6 and use Xcode> = 4.5 and compile with the latest LLVM - for example, see screen capture). And, according to Apple, I should be fine to use them: https://developer.apple.com/library/ios/#releasenotes/ObjectiveC/ObjCAvailabilityIndex/index.html

0x00000001 . Xcode ? lldb gdb

I saw 0x00000001 in lldb when im stepped over the code like this:

labelAttrs = [self someMethod];

If you print labelAttrs before evaluating -someMethod, then it will be assigned 0x00000001.
