解析数据库苹果自带地图

首先把MJExtension 第三方文件拖入到工程里面 Model类和View类里面照常写东西 View里面用xib照常拖

然后在VC.m里面引入#import “AFNetworking/AFNetworking.h”
#import “MJExtension/MJExtension.h”
#import “Model.h” 头文件

主要就是那一行代码

//数组包子店
self.dataSource = [Model mj_objectArrayWithKeyValuesArray:responseObject[@"T1348647853363"]];/* ================  字典包数组==============//        [mjmodel mj_setupObjectClassInArray:^NSDictionary *{//            return   @"类的数组属性":[字典对应的model class ];//        }];*/

接下来是解析部分

-(void)createAFN{

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:@“http://c.m.163.com/nc/article/headline/T1348647853363/0-20.html” parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {

//数组包子店
self.dataSource = [Model mj_objectArrayWithKeyValuesArray:responseObject[@"T1348647853363"]];/* ================  字典包数组==============//        [mjmodel mj_setupObjectClassInArray:^NSDictionary *{//            return   @"类的数组属性":[字典对应的model class ];//        }];*/[self.tbv reloadData];NSLog(@"JSON: %@", responseObject);

} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@“Error: %@”, error);
}];

}

其他部分照常写

                                  FMDB

第一 :
1 把FMDB的第三方拖入到工程里面创建DataModel 继承NSObject ,这个DataModel里面写的是解析的一些数据在整个FMDB里面属于表名在DataModel里面必须定义一个NSInterger 类型的classID 属于主键ID

@interface DataModel : NSObject

@property(nonatomic,strong)NSString *imgsrc,*title,*mtime,*url;

// 设置一个主键ID
@property(nonatomic , assign)NSInteger classID;

@end

下面是DataModel.m里面的方法：
-(void)setValue:(id)value forUndefinedKey:(NSString *)key{

}

第二:在定义一个Model类继承于NSObject 在Model类里面主要写了FMDB的一些增，删，改，查
首先在Model.h里面定义一些方法代码有：

#import <Foundation/Foundation.h>
#import “DataModel.h”
NS_ASSUME_NONNULL_BEGIN

@interface Model : NSObject

//单利方法
+(instancetype)initData;

//初始化数据库
-(void)initSql;
//初始化表格
-(void)initTable;

//添加从解析里面的数据添加到数据库里面所以是DataModel
-(void)addData:(DataModel *)data;

//删除
-(void)deletData:(NSInteger )theid;

//查询数据
-(NSMutableArray *)inquireArr;

//关闭数据库
-(void)closeSql;

@end

其次是Model.m里面的实现的一些方法

#import “Model.h”
#import “FMDatabase.h”
//创建静态变量

static Model *sql;
static FMDatabase *db;

@implementation Model

//初始化单利方法

+(instancetype)initData{
if (!sql) {
sql=[[Model alloc]init];

}
return sql;

}

//初始化数据库

-(void)initSql{

//获取Documents目录
NSString *str=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject];

//拼接路径
NSString *fileName=[str stringByAppendingString:@“strmb.db”];

NSLog(@"%@",fileName);

//创建数据库
db=[[FMDatabase alloc]initWithPath:fileName];

if ([db open]) {
NSLog(@“打开数据库成功”);

//初始化表格
[self initTable];

}else{

NSLog(@"打开数据库失败");

}

//初始化表格
-(void)initTable{
//初始化数据库表格的格式：create table if not exists 表名(主键id integer primary key,所有的数据类型); : 如果不存在DataModel(classID integer primary key,imgsrc blob,title text,url text)，则创建表

[db executeUpdate:@“create table if not exists DataModel(classID integer primary key,imgsrc blob,title text,url text,mtime text)”];
//关闭数据库
[db close];

}
//添加数据
-(void)addData:(DataModel *)data{
//添加数据的sql语句：insert into 表名 values(null,?,?);
if ([db open]) {
[db executeUpdate:[NSString stringWithFormat:@“insert into DataModel values(null,’%@’,’%@’,’%@’,’%@’)”,data.imgsrc,data.title,data.url,data.mtime]];
NSLog(@“插入成功”);

}else{
NSLog(@“添加失败”);
}
//关闭数据库
[db close];

}

//删除数据
-(void)deletData:(NSInteger)theid{

if ([db open]) {

  //sql 语句： delete from 表名 where 表名的主键id = ?
[db executeUpdate:[NSString stringWithFormat:@"delete from DataModel where classID=%ld",theid]];
NSLog(@"删除成功");

}else{
NSLog(@“删除失败”);
}
//关闭数据库
[db close];

}
//查询数据库
-(NSMutableArray *)inquireArr{

//创建数据
NSMutableArray *arr=[NSMutableArray new];

//集合
FMResultSet *set=[FMResultSet new];

if ([db open]) {

set=[db executeQuery:@"select *from DataModel"];
//判断有没有东西while ([set next]) {DataModel *model=[[DataModel alloc]init];model.imgsrc=[set stringForColumn:@"imgsrc"];model.title=[set stringForColumn:@"title"];model.url=[set stringForColumn:@"url"];model.mtime = [set stringForColumn:@"mtime"];model.classID=[set intForColumn:@"classID"];[arr addObject:model];}

}else{
NSLog(@“查询失败”);
}
[db close];
return arr;

}

@end

第三:创建TableViewCell继承UITableViewCell 进行拖拽xib约束

其次是拖拽到TableViewCell.h里面

#import <UIKit/UIKit.h>
#import “DataModel.h”
NS_ASSUME_NONNULL_BEGIN

@interface TableViewCell : UITableViewCell
@property (weak, nonatomic) IBOutlet UIImageView *img;
@property (weak, nonatomic) IBOutlet UILabel *zhu;
@property (weak, nonatomic) IBOutlet UILabel *fu;

-(void)loadData:(DataModel *)mode;

然后在TableViewCell.m里面实现方法

-(void)loadData:(DataModel *)mode{

if (mode) {

self.zhu.text=mode.title;
self.fu.text=mode.mtime;
self.img.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:mode.imgsrc]]];

}

第三：是在VC里面进行解析接口添加到表格里面

#import “ViewController.h”
#import <AFNetworking.h>
#import “TableViewCell.h”
#import “DataModel.h”
#import “oneViewController.h”
#import “twoViewController.h”

@interface ViewController ()<UITableViewDelegate,UITableViewDataSource>
@property(nonatomic,strong)UITableView *tab;
@property(nonatomic,strong)NSMutableArray *DATAsource;

@end

@implementation ViewController

(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.DATAsource=[[NSMutableArray alloc]init];

self.tab=[[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain];
self.tab.delegate=self;
self.tab.dataSource=self;
self.navigationItem.title=@“好好学习”;
self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@“收藏界面” style:UIBarButtonItemStyleDone target:self action:@selector(click)];

[self.view addSubview:self.tab];
//注册
[self.tab registerNib:[UINib nibWithNibName:@“TableViewCell” bundle:nil] forCellReuseIdentifier:@“cell”];

[self AFN];
}
-(void)click{

twoViewController *two=[twoViewController new];

[self.navigationController pushViewController:two animated:YES];

}

-(void)AFN{

AFHTTPSessionManager *manger=[AFHTTPSessionManager manager];

manger.responseSerializer=[AFHTTPResponseSerializer serializer];

[manger GET:@“http://c.m.163.com/nc/article/list/T1348648517839/0-20.html” parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@“请求成功”);

NSDictionary *dic=[NSJSONSerialization JSONObjectWithData:responseObject options:1 error:nil];NSDictionary *arr=[dic objectForKey:@"T1348648517839"];for (NSDictionary *dic in arr) {DataModel *model=[DataModel new];[model setValuesForKeysWithDictionary:dic];[self.DATAsource addObject:model];}
dispatch_async(dispatch_get_main_queue(), ^{[self.tab reloadData];
});

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

NSLog(@"请求失败");

}];

}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return self.DATAsource.count;

}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

TableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@“cell”];

//
//
// if (cell==nil) {
// cell=[[TableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:oj];
// }

DataModel *model=self.DATAsource[indexPath.row];
self.tab.rowHeight=150;

cell.zhu.text=model.title;
cell.fu.text=model.mtime;
cell.img.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:model.imgsrc]]];

return cell;

}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

oneViewController *one=[oneViewController new];

one.model= self.DATAsource[indexPath.row];

[self.navigationController pushViewController:one animated:YES];

}

@end

其次创建OneVC

在OneVC.h里面
引入 DataModel.h 进行属性传值

#import <UIKit/UIKit.h>
#import “DataModel.h”
NS_ASSUME_NONNULL_BEGIN

@interface oneViewController : UIViewController
@property(nonatomic,strong)DataModel *model;

@end

其次在OneVC.m里面写网页视图点击收藏显示添加成功

#import “oneViewController.h”
#import <WebKit/WebKit.h>
#import “Model.h”

@interface oneViewController ()
@property(nonatomic,strong)WKWebView *webview;
@end

@implementation oneViewController

(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

self.webview=[[WKWebView alloc]initWithFrame:self.view.frame];

self.navigationItem.title=@“网页视图”;
self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithTitle:@“收藏” style:UIBarButtonItemStyleDone target:self action:@selector(click)];

[self.webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",self.model.url]]]];

[self.view addSubview:self.webview];

}

-(void)click{

[[Model initData]initSql];

[[Model initData]addData:self.model];

}
@end

最后一步创建TwoVC 是收藏的界面里面显示收藏成功的数据和一些删除数据的展示在这里还可以运用自定义cell直接赋值注册cell

#import “twoViewController.h”
#import “Model.h”
#import “TableViewCell.h”
@interface twoViewController ()<UITableViewDelegate,UITableViewDataSource>
@property(nonatomic,strong)UITableView *tab;
@property(nonatomic,strong)NSMutableArray *arr;

@end

@implementation twoViewController

(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

self.tab=[[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain];

self.tab.delegate=self;
self.tab.dataSource=self;
[self.view addSubview:self.tab];
//注册cell
[self.tab registerNib:[UINib nibWithNibName:@“TableViewCell” bundle:nil] forCellReuseIdentifier:@“cell”];

self.arr=[[NSMutableArray alloc]init];

}

-(void)viewWillAppear:(BOOL)animated{

[[Model initData]initSql];

self.arr=[[Model initData]initeArr];

[self.tab reloadData];

}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

return self.arr.count;
1
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

static NSString *oj=@“cell”;

TableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:oj];

DataModel *model=self.arr[indexPath.row];
self.tab.rowHeight=150;

cell.zhu.text=model.title;
cell.fu.text=model.mtime;
cell.img.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:model.imgsrc]]];

return cell;

}

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{

[[Model initData]initSql];

[[Model initData]deletData:[self.arr[indexPath.row]classID]];

[self.arr removeObject:self.arr[indexPath.row]];
[self.tab reloadData];

}

@end

                                    苹果自带地图1.创建导航 在导航上创建定位按钮

2.引入两个依赖库一个是地图的一个是定位的

此处导两个库

在VC.m里面：
引入两个框架地图和定位的框架

#import “ViewController.h”
//引入头文件 ‘地图框架’
#import <MapKit/MapKit.h>
//引入头文件 ‘定位框架’
#import <CoreLocation/CoreLocation.h>
@interface ViewController ()<MKMapViewDelegate , CLLocationManagerDelegate>
//定义属性 ‘地图视图’
@property(nonatomic,strong)MKMapView *MapView;
//定义属性 ‘地理位置管理者’
@property(nonatomic,strong)CLLocationManager *locManager;
@end

@implementation ViewController

(void)viewDidLoad {
[super viewDidLoad];

self.title = @“地图”;
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@“附近违章高发地” style:UIBarButtonItemStyleDone target:self action:@selector(click)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@“定位” style:UIBarButtonItemStyleDone target:self action:@selector(currentBtnDidPress:)];

//初始化MKMapView ‘地图视图’
self.MapView = [[MKMapView alloc]initWithFrame:self.view.frame];
//设置地图的样式 ‘MKMapTypeSatellite卫星地图’ ‘MKMapTypeStandard平面地图’
self.MapView.mapType = MKMapTypeStandard;
//签订协议
self.MapView.delegate = self;
//添加到视图
[self.view addSubview:self.MapView];

//实例化位置管理者对象
self.locManager = [[CLLocationManager alloc]init];
//签订协议
self.locManager.delegate = self;
//申请用户授权
[self.locManager requestWhenInUseAuthorization];

}
-(void)click{

// NextViewController *next = [[NextViewController alloc]init];
// [self.navigationController pushViewController:next animated:YES];

}
//获取当前按钮触发
-(void)currentBtnDidPress:(id)sender{

//开始获取位置信息，调用此方法后，协议中的方法才会执行
[self.locManager startUpdatingLocation];//通过位置管理者开始位置更新

}

//获取当前位置信息后触发的回调方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{

//获取当前位置 CLLocation位置 locations位置信息一个数组,获取最后一个最新的位置信息
CLLocation *cation = [locations lastObject];
//获取经纬度 coordinate坐标 ‘经纬度=当前位置的坐标’
CLLocationCoordinate2D locationCoor = cation.coordinate;
//输出一下位置信息 longitude经度 latitude纬度
NSLog(@“位置：经度:%g,纬度:%g”,locationCoor.longitude,locationCoor.latitude);

//让地图的显示区缩小 MKCoordinateRegion显示区传入一个经纬度和两个需要缩成的大小
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(locationCoor, 180, 180);
//添加到地图视图上给地图缩小
[self.MapView setRegion:region animated:YES];

//反向地址解析，将经纬度转换为字符串
//初始化地址解析 ‘CLGeocoder地址解析’
CLGeocoder *geocoder = [[CLGeocoder alloc]init];
//解析 reverseGeocodeLocation传入一个位置
[geocoder reverseGeocodeLocation:cation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {

//获取其中的一个地址信息
CLPlacemark *place = [placemarks lastObject];//做一个大头针
//初始化一个描点
MKPointAnnotation *point = [[MKPointAnnotation alloc]init];
//设置大头针的标题   显示当前的位置信息
point.title = [NSString stringWithFormat:@"我的位置：%@",place.name];
//设置大头针显示的经纬度  传入locationCoor当前的经纬度
point.coordinate = locationCoor;
//添加到地图上   必须是Annotation的类型
[self.MapView addAnnotation:point];

}];

}
//设置锚点视图的回调方法，当地图调用addAnnotation：方法时会触发点击大头针是触发的方法
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation{
//静态字符串标识
static NSString *iden = @“pin”;
//初始化描点视图
MKPinAnnotationView *pin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:iden];

//设置掉落状态
pin.animatesDrop = YES;
//设置泡泡效果
pin.canShowCallout = YES;

return pin;

}

@end
