UI总结

selectImage、tintColor的设置

通过KeyPath Type Value 设置

静态表只能用在UITableViewController里面（直接拖NavigationCotroller即可）

声明初始化方法

-(instancetype)initWithDictionary:(NSDictionary *)dict;+(instancetype)tgMdoelWithDictionary:(NSDictionary *)dict;

方法的实现

-(instancetype)initWithDictionary:(NSDictionary *)dict{    if(self = [super init])    {        [self setValuesForKeysWithDictionary:dict];    }    return self;}+(instancetype)tgMdoelWithDictionary:(NSDictionary *)dict{    return [[self alloc]initWithDictionary:dict];}

数据源初始化(懒加载)

-(NSArray *)tgModel{    if (_tgModel == nil) {        NSString *path = [[NSBundle mainBundle] pathForResource:@"tgs" ofType:@"plist"];        NSArray *array = [NSArray arrayWithContentsOfFile:path];         NSMutableArray *models = [NSMutableArray array];        for (NSDictionary *dict in array) {            TGModel *model = [TGModel tgMdoelWithDictionary:dict];            //把model加到可变数组models中            [models addObject:model];        }        //        _tgModel = models;    }    //    return _tgModel;}

重写set方法

-(void)setTgModel:(TGModel *)tgModel{    _tgModel = tgModel;    _imgView.image = [UIImage imageNamed:tgModel.icon];    _titile.text = tgModel.title;    _price.text = tgModel.price;    _buycount.text = tgModel.buycount;    }

UITableViewDataSource

---

注册单元格(加在ViewDidLoad中)

1、Nib注册    [_tableView registerNib:[UINib nibWithNibName:@"TGTableViewCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:identifier];2、注册单元格的类

组数

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{    return 1;}

行数

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{    return self.tgModels.count;}

单元格

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    //xib（可复用单元格）    //自定义的单元格    TGTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];    //对cell的属性设置    TGModel *model = self.tgModels[indexPath.row];    cell.tgModel = model;      return cell;}

添加tableView的头视图

-(void)addHeaderViewForTableView{    //表格的头视图设置的时候，对头视图设置frame    //设置section的头视图的时候，需要设置头视图的高    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, ScreenW, 100)];    scrollView.contentSize = CGSizeMake(ScreenW * 3, 100);       scrollView.pagingEnabled = YES;    for (int i = 0; i < 3; i++) {        UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(ScreenW * i , 0, ScreenW, 100)];        NSString *imageName = [NSString stringWithFormat:@"new_feature_%d",i + 1];        imageView.image = [UIImage imageNamed:imageName];        //把imageView添加到scrollView上        [scrollView addSubview:imageView];    }    //把scrollView添加到头视图上    _tableView.tableHeaderView = scrollView;}

压栈(代理里的)

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

加载网页

 UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.frame][self.view addSubview:webView];  webView.delegate = self;//创建URLNSURL *url = [NSURL URLWithString:self.urlString];//根据创建的URL创建一个请求NSURLRequest *request = [NSURLRequest requestWithURL:url];//加载请求[webView loadRequest:request]; 

UIWebViewDelegate

- (void)webViewDidStartLoad:(UIWebView *)webView;- (void)webViewDidFinishLoad:(UIWebView *)webView;- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error;

风火轮

[UIApplication sharedApplication].networkActivityIndicatorVisible = Bool;

设置UIBarButtonItem（以左Item为例）

-(void)setLeftBarBtnItem{    UIBarButtonItem *leftBarBtnItem = [[UIBarButtonItem alloc] initWithTitle:@"编辑" style:UIBarButtonItemStylePlain target:self action:@selector(edit:)];    //    self.navigationItem.leftBarButtonItem = leftBarBtnItem;}

编辑

---

删除

-(BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{    return YES;}-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{    return UITableViewCellEditingStyleDelete;}-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{    if (editingStyle == UITableViewCellEditingStyleDelete) {        //先删数据源（必须将数据源tgModel给改为可变数组）        [self.tgModels removeObjectAtIndex:indexPath.row];        //移除界面（删除单元格的indexPath）        [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationLeft];    }}

移动

-(BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath{    return YES;}-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{    //源的indexPath中取到要移动的行的数据    TGModel *model = self.tgModels[sourceIndexPath.row];    //从源的数据（tgModel）里将当前的数据（model）移除    [self.tgModels removeObjectAtIndex:sourceIndexPath.row];    //把当前数据插入到目标的indexPath位置    [self.tgModels insertObject:model atIndex:destinationIndexPath.row];}

搜索

-(void)addSearchController{    //创建搜索结果的视图控制器    TGResultTableViewController *tgResultVC = [[TGResultTableViewController alloc]initWithStyle:UITableViewStylePlain];    //赋值（搜索的数据上是tgModels里的数据）    tgResultVC.array = self.tgModels;    //初始化、把结果对象给searchController    _searchController = [[UISearchController alloc] initWithSearchResultsController:tgResultVC];    //searchController的属性    //是否掩藏导航栏    _searchController.hidesNavigationBarDuringPresentation = YES;    //朦版    _searchController.dimsBackgroundDuringPresentation = YES;    //设置更新对象    _searchController.searchResultsUpdater = tgResultVC;}- (IBAction)search:(UIBarButtonItem *)sender {    //把结果的视图控制器弹出    [self presentViewController:_searchController animated:YES completion:nil];}

数据过滤(UISearchResultsUpdating代理必须实现的方法)

- (void)updateSearchResultsForSearchController:(UISearchController *)searchController{    NSString *filterString = searchController.searchBar.text;    //数据过滤    if (filterString .length == 0) {        _result = self.array;    }else{        //过滤每一个数据模型        //过滤标题        NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.title CONTAINS[CD] %@",filterString];        _result = [self.array filteredArrayUsingPredicate:predicate];    }    //刷新表格    [self.tableView reloadData];}
