IOS-MVC层读取服务器接口JSON数据

此篇文章主要讲述获取服务器json接口数据，以便大家在今后的物联网信息时代，移动数据肯定都是需要网络数据的，那么就需要用一个分布集中，整体化的，规范性的创建所需的文件，同时方便以后维护；

分别为：m(model)，m(manager)，v(view)，c(cell)，c(controller);

具体程序如下：

一：ysmasonrymanager.h

#import <foundation/foundation.h>
#import "basemanager.h"
#import "ysmasonrymodel.h"


@protocol ysmasonrymanagerdelegate <nsobject>

-(void)networksuccess:(ysmasonrymodel *_nullable)result;

-(void)networkfail:(nsstring *_nullable)result;

@end

ns_assume_nonnull_begin

@interface ysmasonrymanager : basemanager

@property(weak,nonatomic) id<ysmasonrymanagerdelegate> delegate;

-(void)getdeviceproile:(nsstring *)limit offset:(nsstring *)offset;

@end

ns_assume_nonnull_end

二：ysmasonrymanager.m

#import "ysmasonrymanager.h"

@implementation ysmasonrymanager

-(void)getdeviceproile:(nsstring *)limit offset:(nsstring *)offset{
  
  nsstring *strurl = [nsstring stringwithformat:@"%@api/internal/profile",device_base_url];
  
  //json 
  [ppnetworkhelper setrequestserializer:pprequestserializerhttp];
  [ppnetworkhelper setresponseserializer:ppresponseserializerjson];
  //配置jwt文件
  [ppnetworkhelper setvalue:userjwtkeys forhttpheaderfield:@"grpc-metadata-authorization"];
  
  [ppnetworkhelper get:strurl parameters:@"" success:^(id responseobject){
    ysmasonrymodel *net = [ysmasonrymodel mj_objectwithkeyvalues:responseobject];
    if(net.organizations.count>0){
      if([self.delegate respondstoselector:@selector(networksuccess:)]){
        [self.delegate networksuccess:net];
      }
    }else{
      if([self.delegate respondstoselector:@selector(networkfail:)]){
        [self.delegate networkfail:@"get fail!"];
      }
    }
    
  } failure:^(nserror *error){
    // nserror *newerror = [nserror returnerrorwitherror:error];
    if([self.delegate respondstoselector:@selector(networkfail:)]){
      [self.delegate networkfail:@"cc"];
    }
  }];
}

@end

分析：

#import "basemanager.h"//头部manager对象
#import "ysmasonrymodel.h"//模型层

三：ysmasonrymodel.h

#import <foundation/foundation.h>
#import "basemodel.h"
#import "ysmasonrypilemodel.h"

+(nsdictionary*)mj_objectclassinarray;

@end

ns_assume_nonnull_end

四：ysmasonrymodel.m

#import "ysmasonrymodel.h"

@implementation ysmasonrymodel

+(nsdictionary*)mj_objectclassinarray{
  return @{@"organizations":[ysmasonrypilemodel class],};
}

@end

五：ysmasonrypilemodel.h

-(id)initwithdict:(nsdictionary*)dict;

@end

ns_assume_nonnull_end

六：ysmasonrypilemodel.m

#import "ysmasonrypilemodel.h"

@implementation ysmasonrypilemodel

{
  return @{@"uid": @"uid"};
}

-(id)initwithdict:(nsdictionary*)dict{
  if(self = [super init]){
    self.createdat = dict[@"createdat"];
    //@"gatewaydiscoveryenabled":@(enable),
    self.isadmin = dict[@"isadmin"];
    self.organizationid = dict[@"organizationid"];
    self.organizationname = dict[@"networkserverid"];
    self.updatedat = dict[@"updatedat"];
    
     self.disableassignexistingusers = dict[@"disableassignexistingusers"];
    
    self.email = dict[@"email"];
    self.uid = dict[@"id"];
    self.isactive = dict[@"isactive"];
    self.note = dict[@"note"];
    self.sessionttl = dict[@"sessionttl"];
    self.username = dict[@"username"];
  }
  return self;
}

@end

十三：所用到的常量一些定义：

constants.h

#import <foundation/foundation.h>

#define base_url @"http://110.22.33/illorawan/"

#define userjwtkeys @"eyjhbgcioijiuzi1niisinr5cci6ikpxvcj9.eyjpc3mioijsb3jhlwfwcc1zzxj2zxiilcjhdwqioijsb3jhlwfwc"

至此！

以上详细的代码，主要就是mode数据层那，修改自己的json的返回数据，与一些字典类型的转换，就没其他的难点了。这样写的主要目的是，思路逻辑更清晰，后期维护也简单，分开着写代码更简洁。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
