Incompatible type for NSStringFromSize([self intercellSpacing])?

Question

Something quite strange is happening in my IKImageBrowserView subclass:

I'm trying to print the size of intercellSpacing and cellSize respectively.

CBDebug(@"intercellSpacing %@", NSStringFromSize([self intercellSpacing]));
CBDebug(@"cellSize %@", NSStringFromSize([self cellSize]));

The second line is absolutely fine but the first one doesn't compile:

Incompatible type for argument 1 of 'NSStringFromSize'.

However the two functions are returning the same type:

- (NSSize)intercellSpacing
- (NSSize)cellSize

The SDK used in xCode are 10.6. What am I doing wrong ?

thanks

Answer 1

Make sure your deployment target is set to 10.6.

With that setting set to any earlier version, you can't use anything that didn't exist yet on 10.6, which is when -[IKImageBrowserView intercellSpacing] was introduced.
