#Alternative Objective-C User Defined Literals AOCUDL was inspired by Dustin Bachrach's OCUDL.
The purpose of AOCUDL is to provide a simple way to define custom literals for Objective-C. These are correctly typecast, extensible and flexible.
To add this to your project using CocoaPods just add the following to your podfile:
pod 'AOCUDL', '~> 1.0'
##Example
NSURLRequest *request = $(NSURLRequest)[@"http://hypercrypt.net"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
or simply
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:$(NSURLRequest)[@"http://hypercrypt.net"] delegate:self];
This functionality is provided by using Objective-C subscripting and a small macro to glue the whole thing together:
#define $(cls) (cls *)((id)[cls class])
For a custom class to support AOCUDL all that needs to be implemented is one (or both) of the following methods:
+ (instancetype)objectAtIndexedSubscript:(NSUInteger)index;
+ (instancetype)objectForKeyedSubscript:(id)key;
The default implementation on NSObject
is to return nil
.
##Useful Literals AOCUDL includes a few literals for built-in classes, they broadly match those included by OCUDL. Examples:
NSMutableURLRequest
:$(NSMutableURLRequest)[@"http://hypercrypt.net"]
- This creates a GET requestNSNull
:$NSNull
or$(NSNull)[any-id-or-NSUInteger]
NSSet
:$(NSSet)[@[object1, object2, object3]]
NSURLRequest
:$(NSURLRequest)[@"http://hypercrypt.net"]
- This creates a GET requestNSURL
:$(NSURL)[@"http://hypercrypt.net"]
NSUUID
:$(NSUUID)[@"8DFD5DF3-6D8B-4DC4-B0A2-1F8ED614FC16"]
UIColor
:$(UIColor)[0xff0000]
UIImage
:$(UIImage)[@"testImage"]
UINib
:$(UINib)[@"AOCUDLViewController"]
UIStoryboard
:$(UIStoryboard)[@"Main_iPhone"]
