项目创建
1、获取项目所需的相关素材，界面效果图，界面的素材，以及拿到网络接口等。
2、创建项目，项目中创建一些逻辑文件夹，用来存放相应的文件，清晰的展示
引入AFNetworking;
3、各个ViewController的设计，设计多个界面分别展示。
#import "RootViewController.h" #import "ApplistViewController.h" #import "HotViewController.h" #import "ScaleViewController.h" #import "TopicViewController.h" #import "FreeViewController.h" #import "LimitViewController.h"
4.创建RootViewController的导航栏以及标签栏（此过程中进行了封装）
4.1 继承UIImageView 的类别创建，便于后期创建多个button,或者多个Label
//添加系统按钮 -(UIButton *) addSystemButtonWithFrame: (CGRect )frame title:(NSString *)title action:(void (^)(UIButton *button))action{ JayzyButton *button =[JayzyButton buttonWithType:UIButtonTypeSystem]; button.frame =frame; [button setTitle:title forState:UIControlStateReserved]; button.action =action; [self addSubview:button]; return button; } //添加图片按钮 -(UIButton *) addImageButtonWithFrame: (CGRect )frame title:(NSString *)title background:(NSString *) background action:(void (^)(UIButton *button))action{ JayzyButton *button =[JayzyButton buttonWithType:UIButtonTypeSystem]; button.frame =frame; [button setTitle:title forState:UIControlStateReserved]; [button setBackgroundImage:[UIImage imageNamed:background] forState:UIControlStateNormal]; button.action =action; [self addSubview:button]; return button; } //添加imageView -(UIImageView*) addImageViewWithFrame: (CGRect )frame image:(NSString *)image{ UIImageView *imageView =[[UIImageView alloc] initWithFrame:frame]; imageView.image =[UIImage imageNamed:image]; imageView.userInteractionEnabled =YES; [self addSubview:imageView]; return imageView; } //添加标签 -(UILabel *) addLabelWithFrame: (CGRect )frame text:(NSString *)text{ UILabel *label =[[UILabel alloc] initWithFrame:frame]; label.text =text; [self addSubview:label]; return label; }
4.2 需要创建5个视图由标签控制器控制，统一进行封装，传入类别，标签Title,标签背景图片
//快速添加一个试图控制器 -(UIViewController *) addViewController:(Class)cls title :(NSString *)title image: (NSString *) image { //cls 传入界面所对应的类 UIViewController *vc =[[cls alloc] init]; vc.title =title; UINavigationController *nc =[[UINavigationController alloc] initWithRootViewController:vc]; nc.tabBarItem.image =[UIImage imageNamed:image]; //添加到标签中 NSMutableArray *marr =[[NSMutableArray alloc] initWithArray:self.viewControllers]; [marr addObject:nc]; self.viewControllers =marr; //返回创建的试图控制器 return vc; }
4.3 开始设置首页导航栏的左右按钮
[self configNavigationButton]; #pragma mark ------配置导航条 -(void)configNavigationButton { //要创建多个button的时候，要设置多个视图 UIButton *leftButton =[UIButton buttonWithType:UIButtonTypeSystem]; leftButton.frame =CGRectMake(0, 0, 45, 30); [leftButton setTitle:@"分类" forState:UIControlStateNormal]; [leftButton setBackgroundImage:[UIImage imageNamed:@"buttonbar_action.png"] forState:UIControlStateNormal]; [leftButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; leftButton.titleLabel.font =[UIFont systemFontOfSize:14.0f]; [leftButton addTarget:self action:@selector(dealleftClick:) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *leftItem =[[UIBarButtonItem alloc] initWithCustomView:leftButton]; self.navigationItem.leftBarButtonItem =leftItem; //添加右导航 UIButton *rightButton =[UIButton buttonWithType:UIButtonTypeSystem]; rightButton.frame =CGRectMake(0, 0, 45, 30); [rightButton setTitle:@"设置" forState:UIControlStateNormal]; [rightButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [rightButton setBackgroundImage:[UIImage imageNamed:@"buttonbar_action.png"] forState:UIControlStateNormal]; rightButton.titleLabel.font =[UIFont systemFontOfSize:14.0f]; [rightButton addTarget:self action:@selector(dealrightClick:) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *rightItem =[[UIBarButtonItem alloc] initWithCustomView:rightButton]; self.navigationItem.rightBarButtonItem =rightItem; }
4.4下载数据进行解析，配置页面的UITableView
_dataArray=[[NSMutableArray alloc] init]; _page =1; _categoryId =@"";//URL接口中" "表示全部 [self startDownloadData]; ============ =============== -(void)startDownloadData { //下载数据，JSON的解析 NSString *urlString =[NSString stringWithFormat:LIMIT_URL,_page,_categoryId]; AFHTTPRequestOperationManager *manager =[AFHTTPRequestOperationManager manager]; manager.responseSerializer =[AFHTTPResponseSerializer serializer]; [manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { //进行JSON格式的解析 NSDictionary *dict =[NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil]; // NSLog(@"dict = %@",dict); NSArray *appList = dict[@"applications"]; for(NSDictionary *appDict in appList){ //这里先创建数据模型model [self creatModelCodeWithDictionary:appDict name:@"AppModel"]; //kvc,如果键值没有对应的属性，会崩溃。 AppModel *model =[[AppModel alloc] init]; [model setValuesForKeysWithDictionary:appDict]; model.desc =appDict[@"description"]; [_dataArray addObject:model]; } [_tableView reloadData]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { }]; }
4.5 根据下载的数据分析，创建数据模型。
//创建model的代码,根据字典生成代码 -(void)creatModelCodeWithDictionary:(NSDictionary *)dict name :(NSString *)name { printf("\n@interface %s:NSObject\n",name.UTF8String); for(NSString *key in dict){ printf("@property(copy,nonatomic) NSString *%s;\n",key.UTF8String); } printf("@end\n"); } ============================================ @interface AppModel:NSObject @property(copy,nonatomic) NSString *priceTrend; @property(copy,nonatomic) NSString *expireDatetime; @property(copy,nonatomic) NSString *fileSize; @property(copy,nonatomic) NSString *categoryName; @property(copy,nonatomic) NSString *ipa; @property(copy,nonatomic) NSString *itunesUrl; @property(copy,nonatomic) NSString *name; @property(copy,nonatomic) NSString *version; @property(copy,nonatomic) NSString *currentPrice; @property(copy,nonatomic) NSString *starCurrent; @property(copy,nonatomic) NSString *starOverall; @property(copy,nonatomic) NSString *favorites; @property(copy,nonatomic) NSString *iconUrl; @property(copy,nonatomic) NSString *releaseNotes; @property(copy,nonatomic) NSString *releaseDate; @property(copy,nonatomic) NSString *updateDate; @property(copy,nonatomic) NSString *slug; @property(copy,nonatomic) NSString *downloads; @property(copy,nonatomic) NSString *lastPrice; @property(copy,nonatomic) NSString *ratingOverall; @property(copy,nonatomic) NSString *applicationId; @property(copy,nonatomic) NSString *desc;//改成了 @property(copy,nonatomic) NSNumber *categoryId;//修改 @property(copy,nonatomic) NSString *shares;//修改 @end
4.6 创建UITableView ,展示数据
#pragma mark ---表格视图显示数据 -(void)createTableView { _tableView =[[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain]; _tableView.dataSource=self; _tableView.delegate =self; [self.view addSubview:_tableView]; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return _dataArray.count; } -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 100; } -(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellID =@"cell"; AppCell *cell =[tableView dequeueReusableCellWithIdentifier:cellID]; if (cell ==nil) { cell =[[AppCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellID]; } AppModel *model =_dataArray[indexPath.row]; // cell.textLabel.text =model.name; [cell.iconImageView setImageWithURL:[NSURL URLWithString:model.iconUrl]]; // cell.nameLable.text =model.name; cell.nameLable.text =[NSString stringWithFormat:@"%d.%@",indexPath.row+1,model.name]; // cell.priceLabel.text =model.lastPrice; cell.priceLabel.text =[NSString stringWithFormat:@"￥%.2f",model.lastPrice.doubleValue]; cell.categoryLabel.text =model.categoryName; [cell.starView setStar:model.starCurrent.doubleValue]; cell.shareLabel.text =[NSString stringWithFormat:@"分享:%d",model.shares.intValue]; cell.favoriteLabel.text =[NSString stringWithFormat:@"收藏:%d",model.favorites.intValue]; cell.downloadLabel.text =[NSString stringWithFormat:@"下载:%d",model.downloads.intValue]; return cell; }
