在CocoaPods导入
pod 'AFNetworking'
pod 'MBProgressHUD'
导入头文件 并建议下头文件
先建头文件
MJExtension.h
AFNetworking.h
MBProgressHUD.h
Model.h
shoucangViewController.h
xiangqingViewController.h
tiaoViewController.h
<UITableViewDelegate,UITableViewDataSource>
@property(nonatomic,strong)UITableView *tab;
@property(nonatomic,strong)NSMutableArray *array;
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"title";
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"收藏" style:UIBarButtonItemStylePlain target:self action:@selector(right)];
[self jiexi];
[self.view addSubview:self.tab];
}
-(void)showMBHudWithMessage:(NSString *)msg{
MBProgressHUD *hud=[[MBProgressHUD alloc]initWithView:self.view];
//设置文本的提示样式
hud.mode=MBProgressHUDModeIndeterminate;
//自动从父视图中移除
hud.removeFromSuperViewOnHide=YES;
hud.label.text=msg;
[self.view addSubview:hud];
[hud showAnimated:YES];
[hud hideAnimated:YES afterDelay:3.0];
}
-(void)jiexi{
//显示一个等待控制器
MBProgressHUD *hud=[[MBProgressHUD alloc]initWithView:self.view];
hud.removeFromSuperViewOnHide=YES;
[self.view addSubview:hud];
[hud showAnimated:YES];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:@"网络链接" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
self.array = [Model mj_objectArrayWithKeyValuesArray:responseObject[@"result"][@"data"]];
[hud hideAnimated:YES];
[self.tab reloadData];
[self showMBHudWithMessage:@"加载成功"];
NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
}
-(UITableView *)tab{
if (!_tab) {
_tab = [[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain];
_tab.dataSource = self;
_tab.delegate = self;
}
return _tab;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return _array.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
if (!cell) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];
}
Model *md = self.array[indexPath.row];
cell.textLabel.text = md.title;
cell.detailTextLabel.text = md.category;
cell.textLabel.numberOfLines = 0;
cell.detailTextLabel.numberOfLines = 0;
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
tiaoViewController *tiao = [[tiaoViewController alloc]init];
Model *ml = self.array[indexPath.row];
tiao.mo = ml;
[self.navigationController pushViewController:tiao animated:YES];
}
-(void)right{
shoucangViewController *shoucang = [[shoucangViewController alloc]init];
[self.navigationController pushViewController:shoucang animated:YES];
}
然后在tiao控制器.h导入
Model.h
@property(nonatomic,strong)Model *mo;
然后.m敲一下代码
datamanager.h
@property(nonatomic,strong)UIWebView *web;
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"内容";
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"收藏" style:UIBarButtonItemStylePlain target:self action:@selector(right)];
self.web = [[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
NSURL *url = [NSURL URLWithString:self.mo.url];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[self.web loadRequest:req];
[self.view addSubview:self.web];
}
-(void)right{
[[datamanager dataModel]zengModel:self.mo];
}
在Model.h里设置变量
@property(nonatomic,strong)NSString *title,*url,*category;
@property(nonatomic,assign)int *ID;
然后在数据库.h里设置增删改查
@interface datamanager : NSObject
+(datamanager *)dataModel;
-(void)zengModel:(id)zeng;
-(void)shanModel:(int)shan;
-(id)chaModel;
@end
然后在数据库.m里
#import "datamanager.h"
#import "Model.h"
#import "FMDB.h"
static datamanager *_defaulthandle = nil;
@interface datamanager()
@property(nonatomic,strong)FMDatabase *fMDB;
@end
@implementation datamanager
+(datamanager *)dataModel{
if (_defaulthandle ==nil) {
_defaulthandle = [datamanager new];
}
return _defaulthandle;
}
+(instancetype)allocWithZone:(struct _NSZone *)zone{
if (!_defaulthandle) {
_defaulthandle = [super allocWithZone:zone];
}
return _defaulthandle;
}
-(FMDatabase *)fMDB{
if (_fMDB == nil)
{
NSString *path =[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject] stringByAppendingPathComponent:@"moview.sqlite"];
NSLog(@"path==%@",path);
_fMDB =[FMDatabase databaseWithPath:path];
[self initTable];
}
return _fMDB;
}
-(void)initTable{
[self.fMDB open];
[self.fMDB executeUpdate:@"CREATE TABLE movie (id INTEGER PRIMARY KEY AUTOINCREMENT,title TEXT,author_name TEXT, url,TEXT)"];
[self.fMDB close];
}
-(void)zengModel:(Model *)zeng{
[self.fMDB open];
[self.fMDB executeUpdateWithFormat:@"insert into movie (title,url) values (%@,%@)",zeng.title,zeng.url];
NSLog(@"收藏成功");
[self.fMDB close];
}
-(void)shanModel:(int)shan{
[self.fMDB open];
[self.fMDB executeUpdateWithFormat:@"DELETE FROM movie WHERE id = %d",shan];
[self.fMDB close];
}
-(id)chaModel{
[self.fMDB open];
NSMutableArray *arr = [[NSMutableArray alloc]init];
FMResultSet *res = [self.fMDB executeQuery:@"SELECT * FROM movie"];
while ([res next]) {
Model *md = [[Model alloc]init];
[arr addObject:md];
md.ID = [res intForColumnIndex:0];
md.title = [res stringForColumnIndex:1];
md.url = [res stringForColumnIndex:2];
}
[self.fMDB close];
return [arr copy ];
}
@end
在收藏里设置内容
Model.h
xiangqingViewController.h
datamanager.h
<UITableViewDelegate,UITableViewDataSource>
@property(nonatomic,strong)UITableView *tab;
@property(nonatomic,strong)NSMutableArray *array;
-(void)viewDidAppear:(BOOL)animated{
self.array = [[datamanager dataModel]chaModel];
[self.tab reloadData];
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.view addSubview:self.tab];
}
-(UITableView *)tab{
if (!_tab) {
_tab = [[UITableView alloc]initWithFrame:self.view.frame style:UITableViewStylePlain];
_tab.dataSource =self;
_tab.delegate = self;
}
return _tab;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return _array.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *reuse = @"reuse";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuse];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:reuse];
}
_tab.rowHeight = 100;
Model *model = self.array[indexPath.row];
cell.textLabel.text = model.title;
cell.textLabel.numberOfLines = 0;
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
xiangqingViewController *xiangqing = [[xiangqingViewController alloc]init];
Model *mode = self.array[indexPath.row];
xiangqing.mod = mode;
[self.navigationController pushViewController:xiangqing animated:YES];
}
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
Model *ml = self.array[indexPath.row];
[[datamanager dataModel]shanModel:ml.ID];
self.array = [[datamanager dataModel]chaModel];
[self.tab reloadData];
}
详情里设置model负责传值
Model.h
@property(nonatomic,strong)Model *mod;
在.m里设置数据库负责传值
datamanager.h
@property(nonatomic,strong)UIWebView *web;
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"详情";
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"收藏" style:UIBarButtonItemStylePlain target:self action:@selector(Clcik)];
self.web = [[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
NSURL *url = [NSURL URLWithString:self.mod.url];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[self.web loadRequest:req];
[self.view addSubview:self.web];
}
-(void)Clcik{
[[datamanager dataModel]zengModel:self.mod];
}
