AnnotationKit

The annotation implementation using Objective-C

0x00 Abstract

an annotation is a form of syntactic metadata that can be added to Objective-C source code, like the java annotation.

0x01 What can it do?

  • @when for event dispatch.
@When(AppLaunched,ViewController,@selector(doLaunched:))
+ (void)doLaunched:(NSNotification *)note
{
    NSLog(@"%@",note);
}

@When(AppEnterForeground,ViewController,@selector(doEnterForeground:))
+ (void)doEnterForeground:(NSNotification *)note
{
    NSLog(@"%@",note);
}

@When(AppEnterBackground,ViewController,@selector(doEnterBackground:))
+ (void)doEnterBackground:(NSNotification *)note
{
    NSLog(@"%@",note);
}

@When(AppResignActive,ViewController,@selector(doResignActive:))
+ (void)doResignActive:(NSNotification *)note
{
    NSLog(@"%@",note);
}

@When(AppBecameActive,ViewController,@selector(doBecameActive:))
+ (void)doBecameActive:(NSNotification *)note
{
    NSLog(@"%@",note);
}
  • @RequestMapping for url route.
//ViewController.m
@RequestMapping(ViewController, "demo://demo/index/")
@implementation ViewController
@end

  1. Subclass the PHAnnotationHandler

  2. use @DefineAnnotation() to define your annotation.

  3. override -(void)handleAnnotationConfig:(NSArray<NSString *>*)configs; to gain your meta data

  4. an example : Use HHRoute to impl my @RequestMapping

    //AKRouteAnnotation.h
    #import <Foundation/Foundation.h>
    #import "AKEngine.h"
    
    //provides the @RequestMapping
    #ifndef RequestMapping
    #define RequestMapping(name,url) \
    class AKEngine; char *const NameGen(name,_url) AnnotationDATA(route) = "{\""#name"\":"#url"}";
    #endif
    
    @interface AKRouteAnnotation : PHAnnotationHandler
    @end

    //AKRouteAnnotaion.m
    #import "AKRouteAnnotaion.h"
    #import "NSDictionary+AnnotationKit.h"
    #import <HHRouter/HHRouter.h>
    @interface AKRouteAnnotaion ()
    @end
     //arg0 :AKRouteAnnotaion for class name, arg1: route which is defined in AnnotationDATA ,
    @DefineAnnotation(AKRouteAnnotaion,route)
    @implementation AKRouteAnnotaion
    - (void)handleAnnotationConfig:(NSArray<NSString *> *)configs {
        for (NSString *map in configs) {
            NSData *jsonData =  [map dataUsingEncoding:NSUTF8StringEncoding];
            NSError *error = nil;
            id json = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
            if (!error) {
                
                if ([json isKindOfClass:[NSDictionary class]] && [json allKeys].count == 1) {
                    NSString *clsName = [[json allKeys] firstObject];
                    NSString *url = [json akSafeObjectForKey:clsName];
                    if (clsName && url) {
                        [[HHRouter shared]map:url toControllerClass:NSClassFromString(clsName)];
                        [self.configs addObject:@{url:clsName}];
                    }
                }
                
            }
        }
    }
