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,assign) NSString *isAdmin;
@property(nonatomic, copy) NSString *organizationID;
@property(nonatomic, copy) NSString *organizationName;
@property(nonatomic, copy) NSString *createdAt;
@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
