具体程序如下：
一：YSMasonryManager.h
#import #import "BaseManager.h"#import "YSMasonryModel.h"@protocol YSMasonryManagerDelegate -(void)networkSuccess:(YSMasonryModel *_Nullable)result;-(void)networkFail:(NSString *_Nullable)result;@enDNS_ASSUME_NONNULL_BEGIN@interface YSMasonryManager : BaseManager@property(weak,nonatomic) id delegate;-(void)getDeviceProile:(NSString *)limit Offset:(NSString *)offset;@endNS_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 #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;@endNS_ASSUME_NONNULL_END
四：YSMasonryModel.m
#import "YSMasonryModel.h"@implementation YSMasonryModel+(NSDictionary*)mj_objectClassInArray{ return @{@"organizations":[YSMasonryPileModel class],};}@end
五：YSMasonryPileModel.h
#import #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;@endNS_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 #import "BaseView.h"NS_ASSUME_NONNULL_BEGIN@interface YSMasonryView : BaseView@property(nonatomic,strong) UITableView *mDevericePile;@endNS_ASSUME_NONNULL_END
八：YSMasonryView.m

九：YSMasonryCell.h
#import #import "BaseCell.h"NS_ASSUME_NONNULL_BEGIN@interface YSMasonryCell : BaseCell@property(nonatomic, strong) UIImageView *mNetImgVw;@property(nonatomic, strong) UILabel *mNetNameLb;@property(nonatomic, strong) UILabel *mNetServerLb;@property(nonatomic, strong) UILabel *mNetTimeLb;@endNS_ASSUME_NONNULL_END
十：YSMasonryCell.m
#import "YSMasonryCell.h"@implementation YSMasonryCell- (void)awakeFromNib { [super awakeFromNib];}- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{ self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; if(self){ UIView *mainView = [[UIView alloc] init]; mainView.layer.cornerRadius = 8; mainView.layer.borderColor = [[UIColor grayColor] CGColor]; mainView.layer.borderWidth = 1; [self addSubview:mainView]; [mainView makeConstraints:^(MASConstraintMaker *make){ make.left.equalTo(self).offset(10); make.right.equalTo(self).offset(-10); make.top.equalTo(self).offset(10); make.bottom.equalTo(self).offset(-10); }]; _mNetImgVw = [[UIImageView alloc] init]; [mainView addSubview:_mNetImgVw]; [_mNetImgVw makeConstraints:^(MASConstraintMaker *make){ make.centerY.equalTo(self); make.left.equalTo(self).offset(20); make.width.equalTo(@25); make.height.equalTo(@25); }]; //Net名称 _mNetNameLb = [[UILabel alloc] init]; _mNetNameLb.textColor = [UIColor grayColor]; _mNetNameLb.font = [UIFont fontWithName:@"Helvetica-Bold" size:16]; _mNetNameLb.textAlignment = NSTextAlignmentLeft; [mainView addSubview:_mNetNameLb]; [_mNetNameLb makeConstraints:^(MASConstraintMaker *make){ make.top.equalTo(mainView).offset(5); make.left.equalTo(self.mNetImgVw).offset(35); make.right.equalTo(mainView).offset(-5); make.height.equalTo(@30); }]; //创建时间 _mNetTimeLb = [[UILabel alloc] init]; _mNetTimeLb.textColor = [UIColor grayColor]; _mNetTimeLb.font = [UIFont fontWithName:@"Helvetica-Bold" size:14]; _mNetTimeLb.textAlignment = NSTextAlignmentRight; [mainView addSubview:_mNetTimeLb]; [_mNetTimeLb makeConstraints:^(MASConstraintMaker *make){ make.top.equalTo(mainView).offset(10); make.right.equalTo(mainView).offset(-10); make.width.equalTo(@160); make.height.equalTo(@30); }]; //端口号 _mNetServerLb = [[UILabel alloc] init]; _mNetServerLb.textColor = [UIColor grayColor]; _mNetServerLb.font = [UIFont fontWithName:@"Helvetica-Bold" size:16]; _mNetServerLb.textAlignment = NSTextAlignmentLeft; [mainView addSubview:_mNetServerLb]; [_mNetServerLb makeConstraints:^(MASConstraintMaker *make){ make.bottom.equalTo(self).offset(-15); make.left.equalTo(self.mNetImgVw).offset(35); make.right.equalTo(mainView).offset(-10); make.height.equalTo(@30); }]; } return self;}- (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated];}@end
十一：YSMasonryContller.h

十三：所用到的常量一些定义：
Constants.h
#import #define BASE_URL @"http://110.22.33/ilLoRaWan/"#define USERJWTKEYS @"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJsb3JhLWFwcC1zZXJ2ZXIiLCJhdWQiOiJsb3JhLWFwc"
