@implementation StudentEntity

#pragma mark - json method
+(NSDictionary *)JSONKeyPathsByPropertyKey
{
	return @{
            @"name":NameJsonKey,

That's the model you want! It contain server json convert to local property!Of course you can add -d option to add database surpport:

ptgen student -l name:string age:int sex:string -s sname:string age:int sex:string -d *t_name t_age t_sex 

*is a table primary key. your must set primary key if you use -d.

If you want your server property name and local property name same , you can use as below:

ptgen DownloadModel -als title:string *imgUrlString:string downloadFinalPath:string totalContentSize:string speed:string retryCount:string isNeedResum:bool type:enum.RoleType

######according server http response If your server respons data is beautiful. you can create model according http response data (this version only support json) as below:

ptgen -ulsd "http://www.i4.cn/ajax.php?a=getoldnewsforpage&itype=2&n=20" -m /:Student

#####future ptgen contain nimbus cell support in version 2. But it's not very good. I will add it in future.If you any useful common function , you can tell . I'll add it in future.
