iOS json字段转属性

最近写程序总是遇到这么一个问题: 网络获取数据后，我们需要将一些信息转为类，方便后面的操作。例如：

list 里面的字段，我们需要转成一个类的属性。例如 转为下面的样子：

@interface OffLinePublicModel  : NSObject@property (nonatomic, strong) NSString *orderno;@property (nonatomic, strong) NSString *status;@property (nonatomic, strong) NSString *statusflag;@property (nonatomic, strong) NSString *Id;@property (nonatomic, strong) NSString *userid;@property (nonatomic, strong) NSString *companyid;@property (nonatomic, strong) NSString *companyname;@property (nonatomic, strong) NSString *areaid;@property (nonatomic, strong) NSString *areaname;@property (nonatomic, strong) NSString *rootid;@property (nonatomic, strong) NSString *parentids;@property (nonatomic, strong) NSString *channelid;@property (nonatomic, strong) NSString *channelname;@property (nonatomic, strong) NSString *isfinish;@property (nonatomic, strong) NSString *releasetime;@property (nonatomic, strong) NSString *title;@property (nonatomic, strong) NSString *desc;@property (nonatomic, strong) NSString *gongsi;@property (nonatomic, strong) NSString *imageurl;@property (nonatomic, strong) NSString *infotype;;@property (nonatomic, strong) NSString *personname;@property (nonatomic, strong) NSString *personphone;@property (nonatomic, strong) NSArray *imagesList;@property (nonatomic, strong) NSString *year;@property (nonatomic, strong) NSString *salary;@property (nonatomic, strong) NSString *edu;@property (nonatomic, strong) NSString *num;@property (nonatomic, strong) NSString *age;@property (nonatomic, strong) NSString *place;@property (nonatomic, strong) NSString *estate;@property (nonatomic, strong) NSString *numshi;@property (nonatomic, strong) NSString *numting;@property (nonatomic, strong) NSString *numwei;@property (nonatomic, strong) NSString *measure;@property (nonatomic, strong) NSString *sheshi;@property (nonatomic, strong) NSString *numlou;@property (nonatomic, strong) NSString *numall;@property (nonatomic, strong) NSString *ispersonal;@property (nonatomic, strong) NSString *money;@property (nonatomic, strong) NSString *qq;@property (nonatomic, strong) NSString *usage;@property (nonatomic, strong) NSString *color;@property (nonatomic, strong) NSString *mode ;-(instancetype)initWithDictionary:(NSDictionary *)dictionary;@end#import "OffLinePublicModel.h"#import "NSDictionary+StringValue.h"@implementation OffLinePublicModel-(instancetype)initWithDictionary:(NSDictionary *)dictionary{    self = [super init];    if (self) {        self.orderno = [dictionary stringValueForKey:@"orderno"];        self.status = [dictionary stringValueForKey:@"status"];        self.statusflag = [dictionary stringValueForKey:@"statusflag"];        self.Id = [dictionary stringValueForKey:@"id"];        self.userid = [dictionary stringValueForKey:@"userid"];        self.companyid = [dictionary stringValueForKey:@"companyid"];        self.companyname = [dictionary stringValueForKey:@"companyname"];        self.areaid = [dictionary stringValueForKey:@"areaid"];        self.areaname = [dictionary stringValueForKey:@"areaname"];        self.rootid = [dictionary stringValueForKey:@"rootid"];        self.parentids = [dictionary stringValueForKey:@"parentids"];        self.channelid = [dictionary stringValueForKey:@"channelid"];        self.channelname = [dictionary stringValueForKey:@"channelname"];        self.isfinish = [dictionary stringValueForKey:@"isfinish"];        self.releasetime = [dictionary stringValueForKey:@"releasetime"];        self.title = [dictionary stringValueForKey:@"title"];        self.desc = [dictionary stringValueForKey:@"desc"];        self.gongsi = [dictionary stringValueForKey:@"gongsi"];        self.imageurl = [dictionary stringValueForKey:@"imageurl"];        self.infotype = [dictionary stringValueForKey:@"infotype"];        self.personname = [dictionary stringValueForKey:@"personname"];        self.personphone = [dictionary stringValueForKey:@"personphone"];        self.imagesList = [dictionary objectForKey:@"imagesList"];        self.year = [dictionary stringValueForKey:@"year"];        self.salary = [dictionary stringValueForKey:@"salary"];        self.edu = [dictionary stringValueForKey:@"edu"];        self.num = [dictionary stringValueForKey:@"num"];        self.age = [dictionary stringValueForKey:@"age"];        self.place = [dictionary stringValueForKey:@"place"];        self.estate = [dictionary stringValueForKey:@"estate"];        self.numshi = [dictionary stringValueForKey:@"numshi"];        self.numting = [dictionary stringValueForKey:@"numting"];        self.numwei = [dictionary stringValueForKey:@"numwei"];        self.measure = [dictionary stringValueForKey:@"measure"];        self.sheshi = [dictionary stringValueForKey:@"sheshi"];        self.numlou = [dictionary stringValueForKey:@"numlou"];        self.numall = [dictionary stringValueForKey:@"numall"];        self.ispersonal = [dictionary stringValueForKey:@"ispersonal"];        self.money = [dictionary stringValueForKey:@"money"];        self.qq = [dictionary stringValueForKey:@"qq"];        self.usage = [dictionary stringValueForKey:@"usage"];        self.color = [dictionary stringValueForKey:@"color"];        self.mode = [dictionary stringValueForKey:@"mode"];    }    return self;}@end

那么，问题来了 。这个要一个一个的敲吗？
苦逼的我一直是挨个敲得 。
今天终于忍不了了，我决定写个东西来缓解一下。但是苦逼的Mac 桌面程序不会写，web不会，怎么办？ 没办法 。只能用Xcode 写一个Command Line Tool
在日志输出栏来操作 ，委屈求全相当蛋疼啊。

int main(int argc, const char * argv[]) {    @autoreleasepool {        // insert code here...        char s[10000] ;        NSMutableArray *StringArray = [NSMutableArray array];        while (gets(s) &&s[0] != '\0') {            NSString *string = [[NSString alloc]initWithCString:s encoding:NSUTF8StringEncoding];            [StringArray addObject:string];        }        for (NSString *string in StringArray) {            NSString *newString  = [string stringByReplacingOccurrencesOfString:@"\"" withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@" " withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@"\n" withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@"\t" withString:@""];            NSArray *array = [newString componentsSeparatedByString:@":"];            newString = array[0];            printf("@property (nonatomic, strong) NSString *%s\n",[newString UTF8String]);        }        printf("\n\n");        for (NSString *string in StringArray) {            NSString *newString  = [string stringByReplacingOccurrencesOfString:@"\"" withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@" " withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@"\n" withString:@""];            newString = [newString stringByReplacingOccurrencesOfString:@"\t" withString:@""];            NSArray *array = [newString componentsSeparatedByString:@":"];            newString = array[0];            printf("self.%s = [[dictionary stringValueForKey:\"%s\"];\n",[newString UTF8String],[newString UTF8String]);        }        printf("\n\n\n\n");    }    return 0;}

复制上面的字段 粘贴到里面 （由于是个小东西）没有错误处理，所以一定要注意哦，只复制要生成属性的字段。

注意粘贴上后 多加两个回车。

输出样例如下：

这里只有NSString 类型的属性，是因为个人觉得 把一些 Int Float 等类型的数据转为NSString更方便以后的操作。 例如 int 类型的 数据是要在Label或其他控件上显示的 ，用的时候还需要转。 当然这个是个人喜好。

上面只是因我个人喜好结果输出的 ，灵活性太低。 可以根据自己的喜好改动一下。

等我学点web方面的知识以后 ，回来完善一下这个功能。
