运行时字典转模型，模型快速转字典
1、直接集成 (directly integrating)
下载zip包解压后， 直接将 “SGModelKeyValues” 文件夹下所有文件拖到你的项目 (Download the zip package decompression, directly under the "SGModelKeyValues" folder to drag all your files to your project)
2、使用CocoaPods (use CocoaPods)
To integrate SGDwonload into your Xcode project using CocoaPods, specify it in your Podfile:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
target 'TargetName' do
pod 'SGModleKeyValues', '~> 1.0.0'
end
Then, run the following command:
$ pod install
转化代码（均转化成功）：
double time1 = CFAbsoluteTimeGetCurrent(); //记录开始时间
NSArray * sgArrays = [SGFirstObject sg_objectArrayFromKeyValues:self.dataSource];
double time2 = CFAbsoluteTimeGetCurrent(); //记录结束时间
NSArray * mjArrays = [SGFirstObject mj_objectArrayWithKeyValuesArray:self.dataSource];
double time3 = CFAbsoluteTimeGetCurrent(); //记录结束时间
NSArray * yyArrays = [NSArray yy_modelArrayWithClass:[SGFirstObject class] json:self.dataSource];
double time4 = CFAbsoluteTimeGetCurrent(); //记录结束时间
NSLog(@"SG %f",time2-time1);
NSLog(@"MJ %f",time3-time2);
NSLog(@"YY %f",time4-time3);
代码：
NSArray * sgArrays = [SGFirstObject sg_objectArrayFromKeyValues:self.dataSource];
double time1 = CFAbsoluteTimeGetCurrent(); //记录开始时间
id sgKeyValues = [sgArrays sg_keyValues];
double time2 = CFAbsoluteTimeGetCurrent(); //记录结束时间
id mjKeyValues = [sgArrays mj_keyValues];
double time3 = CFAbsoluteTimeGetCurrent(); //记录结束时间
id yyKeyValues = [sgArrays yy_modelToJSONObject];
double time4 = CFAbsoluteTimeGetCurrent(); //记录结束时间
NSLog(@"SG %f",time2-time1);
NSLog(@"MJ %f",time3-time2);
NSLog(@"YY %f",time4-time3);
打印结果：

};

从打印结果来看:MJ用时最短，但是数组模型转字典模型失败；YY第一次转化用时较长，但转化一次之后转化效率大大提升; SG转化时间较稳定用时也较短
