Objective-C Runtime技术调研(六)

一、资料归档篇

创建TLPeople.h

#import <Foundation/Foundation.h>

@interfaceTLPeople :NSObject

@property(nonatomic,copy)NSString*name;//姓名

@property(nonatomic,strong)NSNumber*age;//年龄

@property(nonatomic,copy)NSString*occupation;//职业

@property(nonatomic,copy)NSString*nationality;//国籍

@end

TLPeople.m

#import"TLPeople.h"

#if TARGET_IPHONE_SIMULATOR

#import <objc/objc-runtime.h>

#else

#import <objc/runtime.h>

#import <objc/message.h>

#endif

@implementationTLPeople

idvalue = [selfvalueForKey:key];

[aCoderencodeObject:valueforKey:key];

}

-(instancetype)initWithCoder:(NSCoder*)aDecoder
