神剑若水哥：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

2.用XCode打开工程

3.编译工程：Command+B

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

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 #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 #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。
