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"

NS_ASSUME_NONNULL_BEGIN

@interface YSMasonryModel : BaseModel

@property(nonatomic, copy) NSString *settings;

@property(nonatomic, copy) NSArray *organizations;

@property(nonatomic, copy) NSString *user;

+(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

#import <Foundation/Foundation.h>
#import "BaseModel.h"

NS_ASSUME_NONNULL_BEGIN

@interface YSMasonryPileModel : BaseModel

@property(nonatomic, copy) NSString *updatedAt;
@property(nonatomic,assign) NSString *disableAssignExistingUsers;
@property(nonatomic, copy) NSString *email;
@property(nonatomic, copy) NSString *uid;
@property(nonatomic,assign) NSString *isActive;
@property(nonatomic, copy) NSString *note;
@property(nonatomic,assign) NSString *sessionTTL;
@property(nonatomic, copy) NSString *username;

-(id)initWithDict:(NSDictionary*)dict;

@end

NS_ASSUME_NONNULL_END

六：YSMasonryPileModel.m

#import "YSMasonryPileModel.h"

@implementation YSMasonryPileModel

+ (NSDictionary *)mj_replacedKeyFromPropertyName
{
  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

七：YSMasonryView.h

#import <UIKit/UIKit.h>
#import "BaseView.h"

NS_ASSUME_NONNULL_BEGIN

@interface YSMasonryView : BaseView

@property(nonatomic,strong) UITableView *mDevericePile;

@end

    make.left.equalTo(self).offset(0);
    make.right.equalTo(self).offset(0);
    make.bottom.equalTo(self).offset(0);
  }];
}

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我们。
