YYModel ============== [](https://raw.githubusercontent.com/ibireme/YYModel/master/LICENSE)&nbsp; [](https://github.com/Carthage/Carthage)&nbsp; [](http://cocoapods.org/?q= YYModel)&nbsp; [](http://cocoapods.org/?q= YYModel)&nbsp; [](https://travis-ci.org/ibireme/YYModel)&nbsp; [](https://codecov.io/github/ibireme/YYModel?branch=master) High performance model framework for iOS/OSX.<br/> (It's a component of [YYKit](https://github.com/ibireme/YYKit)) Performance ============== Time cost (process GithubUser 10000 times on iPhone 6):  See `Benchmark/ModelBenchmark.xcodeproj` for more benchmark case. Features ============== - **High performance**: The conversion performance is close to handwriting code. - **Automatic type conversion**: The object types can be automatically converted. - **Type Safe**: All data types will be verified to ensure type-safe during the conversion process. - **Non-intrusive**: There is no need to make the model class inherit from other base class. - **Lightwight**: This library contains only 5 files. - **Docs and unit testing**: 100% docs coverage, 99.6% code coverage. Usage ============== ###Simple model json convert // JSON: { "uid":123456, "name":"Harry", "created":"1965-07-31T00:00:00+0000" } // Model: @interface User : NSObject @property UInt64 uid; @property NSString *name; @property NSDate *created; @end @implementation User @end // Convert json to model: User *user = [User yy_modelWithJSON:json]; // Convert model to json: NSDictionary *json = [user yy_modelToJSONObject]; If the type of an object in JSON/Dictionary cannot be matched to the property of the model, the following automatic conversion is performed. If the automatic conversion failed, the value will be ignored. <table> <thead> <tr> <th>JSON/Dictionary</th> <th>Model</th> </tr> </thead> <tbody> <tr> <td>NSString</td> <td>NSNumber,NSURL,SEL,Class</td> </tr> <tr> <td>NSNumber</td> <td>NSString</td> </tr> <tr> <td>NSString/NSNumber</td> <td>C number (BOOL,int,float,NSUInteger,UInt64,...)<br/> NaN and Inf will be ignored</td> </tr> <tr> <td>NSString</td> <td>NSDate parsed with these formats:<br/> yyyy-MM-dd<br/> yyyy-MM-dd HH:mm:ss<br/> yyyy-MM-dd'T'HH:mm:ss<br/> yyyy-MM-dd'T'HH:mm:ssZ<br/> EEE MMM dd HH:mm:ss Z yyyy </td> </tr> <tr> <td>NSDate</td> <td>NSString formatted with ISO8601:<br/> "YYYY-MM-dd'T'HH:mm:ssZ"</td> </tr> <tr> <td>NSValue</td> <td>struct (CGRect,CGSize,...)</td> </tr> <tr> <td>NSNull</td> <td>nil,0</td> </tr> <tr> <td>"no","false",...</td> <td>@(NO),0</td> </tr> <tr> <td>"yes","true",...</td> <td>@(YES),1</td> </tr> </tbody> </table> ###Match model property to different JSON key // JSON: { "n":"Harry Pottery", "p": 256, "ext" : { "desc" : "A book written by J.K.Rowing." }, "ID" : 100010 } // Model: @interface Book : NSObject @property NSString *name; @property NSInteger page; @property NSString *desc; @property NSString *bookID; @end @implementation Book + (NSDictionary *)modelCustomPropertyMapper { return @{@"name" : @"n", @"page" : @"p", @"desc" : @"ext.desc", @"bookID" : @[@"id",@"ID",@"book_id"]}; } @end You can map a json key (key path) or an array of json key (key path) to one or multiple property name. If there's no mapper for a property, it will use the property's name as default. ###Nested model // JSON { "author":{ "name":"J.K.Rowling", "birthday":"1965-07-31T00:00:00+0000" }, "name":"Harry Potter", "pages":256 } // Model: (no need to do anything) @interface Author : NSObject @property NSString *name; @property NSDate *birthday; @end @implementation Author @end @interface Book : NSObject @property NSString *name; @property NSUInteger pages; @property Author *author; @end @implementation Book @end ### Container property @class Shadow, Border, Attachment; @interface Attributes @property NSString *name; @property NSArray *shadows; //Array<Shadow> @property NSSet *borders; //Set<Border> @property NSMutableDictionary *attachments; //Dict<NSString,Attachment> @end @implementation Attributes + (NSDictionary *)modelContainerPropertyGenericClass { // value should be Class or Class name. return @{@"shadows" : [Shadow class], @"borders" : Border.class, @"attachments" : @"Attachment" }; } @end ### Whitelist and blacklist @interface User @property NSString *name; @property NSUInteger age; @end @implementation Attributes + (NSArray *)modelPropertyBlacklist { return @[@"test1", @"test2"]; } + (NSArray *)modelPropertyWhitelist { return @[@"name"]; } @end ###Data validate and custom transform // JSON: { "name":"Harry", "timestamp" : 1445534567 } // Model: @interface User @property NSString *name; @property NSDate *createdAt; @end @implementation User - (BOOL)modelCustomTransformFromDictionary:(NSDictionary *)dic { NSNumber *timestamp = dic[@"timestamp"]; if (![timestamp isKindOfClass:[NSNumber class]]) return NO; _createdAt = [NSDate dateWithTimeIntervalSince1970:timestamp.floatValue]; return YES; } - (BOOL)modelCustomTransformToDictionary:(NSMutableDictionary *)dic { if (!_createdAt) return NO; dic[@"timestamp"] = @(n.timeIntervalSince1970); return YES; } @end ###Coding/Copying/hash/equal/description @interface YYShadow :NSObject <NSCoding, NSCopying> @property (nonatomic, copy) NSString *name; @property (nonatomic, assign) CGSize size; @end @implementation YYShadow - (void)encodeWithCoder:(NSCoder *)aCoder { [self yy_modelEncodeWithCoder:aCoder]; } - (id)initWithCoder:(NSCoder *)aDecoder { self = [super init]; return [self yy_modelInitWithCoder:aDecoder]; } - (id)copyWithZone:(NSZone *)zone { return [self yy_modelCopy]; } - (NSUInteger)hash { return [self yy_modelHash]; } - (BOOL)isEqual:(id)object { return [self yy_modelIsEqual:object]; } - (NSString *)description { return [self yy_modelDescription]; } @end Installation ============== ### CocoaPods 1.
