Method "not available on iOS"

I heard about a function on NSCalendar that had been introduced in iOS7.

Had a look in the docs and couldn't find it. Nor in the OS X docs.

The function is - (BOOL)isDate:(NSDate *)date1 equalToDate:(NSDate *)date2 toUnitGranularity:(NSCalendarUnit)unit i.e. are these two dates on the same day/in the same week/ month, etc...

However, when I try to use it in Xcode 5. The AutoComplete shows it with a red strike through and then when I actually use it I get this error...

enter image description here

It's odd as the function is clearly there I'm just not able to use it.

Can anyone shed light on why this is happening?

Unfortunately it's not available for iOS, only for OS X 10.9. You can always dupe rdar://14995171 to tell Apple that you want it for iOS as well.

If you look in NSCalendar.h in the iOS 7 SDK you will see that these methods are tagged as available since __NSCALENDAR_COND_IOS_7_0 which if you look at the top of the same file is defined as

#if !defined(__NSCALENDAR_COND_IOS_4_0)
#if NS_ENABLE_CALENDAR_NEW_API
#define __NSCALENDAR_COND_IOS_4_0 4_0
#define __NSCALENDAR_COND_IOS_5_0 5_0
#define __NSCALENDAR_COND_IOS_6_0 6_0
#define __NSCALENDAR_COND_IOS_7_0 7_0
#else
#define __NSCALENDAR_COND_IOS_4_0 NA
#define __NSCALENDAR_COND_IOS_5_0 NA
#define __NSCALENDAR_COND_IOS_6_0 NA
#define __NSCALENDAR_COND_IOS_7_0 NA
#endif
#endif

This currently evaluates to NA meaning that these methods are "not available" for iOS.

Where did you hear about that method? It's possible that the method has been removed during the betas of iOS 7.

It's private API: __NSCFCalendar.h
