#define __NI_DEPRECATED_METHOD   __attribute__((deprecated))

Mark a method or property as deprecated to the compiler.

Any use of a deprecated method or property will flag a warning when compiling.

Borrowed from Apple's AvailabiltyInternal.h header.

   __AVAILABILITY_INTERNAL_DEPRECATED         __attribute__((deprecated))

#define NI_FIX_CATEGORY_BUG

(

name

)

Value:

@interface NI_FIX_CATEGORY_BUG_##name @end \
@implementation NI_FIX_CATEGORY_BUG_##name @end

Force a category to be loaded when an app starts up.

Add this macro before each category implementation, so we don't have to use -all_load or -force_load to load object files from static libraries that only contain categories and no classes. See http://developer.apple.com/library/mac/#qa/qa2006/qa1490.html for more info.

#define NI_RELEASE_SAFELY

(

__POINTER

)

{ [__POINTER release]; __POINTER = nil; }

Release and assign nil to an object.

This macro is preferred to simply releasing an object to avoid accidentally using the object later on in a method.

Examples:

ExampleStaticTableModel.m.

#define RGBCOLOR	(		r,
			g,
			b
	)		[UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:1]

Creates an opaque UIColor object from a byte-value color definition.

			g,
			b,
			a
	)		[UIColor colorWithRed:(r)/255.0f green:(g)/255.0f blue:(b)/255.0f alpha:(a)]

Creates a UIColor object from a byte-value color definition and alpha transparency.
