bool -> BOOL  (and hiddenTitle_ -> titleHidden_)

Done.

 }
 
 // Designated initializer.
 // |sourceID| is the corresponding source's ID as provided by the media list.

 // |IKImageBrowserView|.

for simply types we usually just use properties. In the header (before the
initializer above)

@property(assign, nonatomic) BOOL titleHidden;


then in the .mm (also just before the initializer)

@synthesize titleHidden = titleHidden_;

you don't need an implementaiton of - (void)setTitleHidden:
