JSONExport 工具

JSONExport 是把JSONExport 的格式文件转换成为Model 对象的工具。

下面是JSONExport gitHub地址：

一.安装方法：

1.下载代码

image-20191008110408108

2.用XCode打开工程

image-20191008110529415

3.编译工程：Command+B

image-20191008110713609

4.找到软件包：product 文件夹下的包文件，右键，Show in Finder

5.拖入应用程序

二.使用：

1.解析，将下面的json 文字复制到json data 如图

{
"name":"李四",
"age":20,
"cars":["宝马车","路虎车","保时捷"],
"cer":{"Compuer":"l1","Enlish":"4"},
"address":"河南"
}

说明：

1.Person 是RootClass 的名字，

2.FZ 是所有类的前缀，

3.FZBaseModel是所有类的父亲（或者叫基类吧）。

4.是选择开发语言

2.构造方法 Constructor

注意：选中Constructor的时候，会有构造方法，没选中没有构造方法。

2.1选中Constructor：

代码如下:

.h代码：

#import <UIKit/UIKit.h>
#import "FZBaseModel.h"
#import "FZCer.h"

@interface FZPerson : FZBaseModel

@property (nonatomic, strong) NSString * address;
@property (nonatomic, assign) NSInteger age;
@property (nonatomic, strong) NSArray * cars;
@property (nonatomic, strong) FZCer * cer;
@property (nonatomic, strong) NSString * name;

-(instancetype)initWithDictionary:(NSDictionary *)dictionary;
@end

.m 代码

//
//  FZPerson.m
//  Model file generated using JSONExport: https://github.com/Ahmed-Ali/JSONExport
#import "FZPerson.h"

NSString *const kFZPersonAddress = @"address";
NSString *const kFZPersonAge = @"age";
NSString *const kFZPersonCars = @"cars";
NSString *const kFZPersonCer = @"cer";
NSString *const kFZPersonName = @"name";

@interface FZPerson ()
@end
@implementation FZPerson

/**
 * Instantiate the instance using the passed dictionary values to set the properties values
 */
-(instancetype)initWithDictionary:(NSDictionary *)dictionary
{
    self = [super init];
    if(![dictionary[kFZPersonAddress] isKindOfClass:[NSNull class]]){
        self.address = dictionary[kFZPersonAddress];
    }   
    if(![dictionary[kFZPersonAge] isKindOfClass:[NSNull class]]){
        self.age = [dictionary[kFZPersonAge] integerValue];
    }

    if(![dictionary[kFZPersonCars] isKindOfClass:[NSNull class]]){
        self.cars = dictionary[kFZPersonCars];
    }   
    if(![dictionary[kFZPersonCer] isKindOfClass:[NSNull class]]){
        self.cer = [[FZCer alloc] initWithDictionary:dictionary[kFZPersonCer]];
    }

    if(![dictionary[kFZPersonName] isKindOfClass:[NSNull class]]){
        self.name = dictionary[kFZPersonName];
    }   
    return self;
}
@end

3.实用方法方法 Utility methods

选中会有如下三个方法，如果没选中，就没有这四个方法

-(NSDictionary *)toDictionary；
- (void)initWithCoder:(NSCoder *)aCoder；
- (void)encodeWithCoder:(NSCoder *)aCoder
- (instancetype)copyWithZone:(NSZone *)zone

1.toDictionary model 转化为字典。

2.initWithCoder model 归档方法

3.encodeWithCoder model 解归档方法

4.copyWithZone model在 copy 的时候使用

代码如下：

.h代码

#import <UIKit/UIKit.h>
#import "FZBaseModel.h"
#import "FZCer.h"

@interface FZPerson : FZBaseModel

@property (nonatomic, strong) NSString * address;
@property (nonatomic, assign) NSInteger age;
@property (nonatomic, strong) NSArray * cars;
@property (nonatomic, strong) FZCer * cer;
@property (nonatomic, strong) NSString * name;

-(NSDictionary *)toDictionary;
@end

.m代码

//
//  FZPerson.m
//  Model file generated using JSONExport: https://github.com/Ahmed-Ali/JSONExport



#import "FZPerson.h"

NSString *const kFZPersonAddress = @"address";
NSString *const kFZPersonAge = @"age";
NSString *const kFZPersonCars = @"cars";
NSString *const kFZPersonCer = @"cer";
NSString *const kFZPersonName = @"name";

@interface FZPerson ()
@end
@implementation FZPerson




/**
 * Returns all the available property values in the form of NSDictionary object where the key is the approperiate json key and the value is the value of the corresponding property
 */
-(NSDictionary *)toDictionary
{
    NSMutableDictionary * dictionary = [NSMutableDictionary dictionary];
    if(self.address != nil){
        dictionary[kFZPersonAddress] = self.address;
    }
    dictionary[kFZPersonAge] = @(self.age);
    if(self.cars != nil){
        dictionary[kFZPersonCars] = self.cars;
    }
    if(self.cer != nil){
        dictionary[kFZPersonCer] = [self.cer toDictionary];
    }
    if(self.name != nil){
        dictionary[kFZPersonName] = self.name;
    }
    return dictionary;

}

/**
 * Implementation of NSCoding encoding method
 */
/**
 * Returns all the available property values in the form of NSDictionary object where the key is the approperiate json key and the value is the value of the corresponding property
 */
- (void)encodeWithCoder:(NSCoder *)aCoder
{
    if(self.address != nil){
        [aCoder encodeObject:self.address forKey:kFZPersonAddress];
    }
    [aCoder encodeObject:@(self.age) forKey:kFZPersonAge];  if(self.cars != nil){
        [aCoder encodeObject:self.cars forKey:kFZPersonCars];
    }
    if(self.cer != nil){
        [aCoder encodeObject:self.cer forKey:kFZPersonCer];
    }
    if(self.name != nil){
        [aCoder encodeObject:self.name forKey:kFZPersonName];
    }

}

/**
 * Implementation of NSCoding initWithCoder: method
 */
- (instancetype)initWithCoder:(NSCoder *)aDecoder
{
    self = [super init];
    self.address = [aDecoder decodeObjectForKey:kFZPersonAddress];
    self.age = [[aDecoder decodeObjectForKey:kFZPersonAge] integerValue];
    self.cars = [aDecoder decodeObjectForKey:kFZPersonCars];
    self.cer = [aDecoder decodeObjectForKey:kFZPersonCer];
    self.name = [aDecoder decodeObjectForKey:kFZPersonName];
    return self;

}

/**
 * Implementation of NSCopying copyWithZone: method
 */
- (instancetype)copyWithZone:(NSZone *)zone
{
    FZPerson *copy = [FZPerson new];

    copy.address = [self.address copy];
    copy.age = self.age;
    copy.cars = [self.cars copy];
    copy.cer = [self.cer copy];
    copy.name = [self.name copy];

    return copy;
}
@end

4.保存

总结，我自己使用的时候一搬是结合YYModel 使用，所以不需要生成一些构造和辅助方法。一般不选中。
