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("\[email protected] %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;
}
