為期兩天的網易新聞簡單完成,其中還有許多模糊的點,在此發文:
- 一是為了自己總結思路以及再次貫徹一下整個小demo的細節操作
- 二是回顧一下比較遺忘容易忽略的知識點
- 三是為了激勵自己的開發興趣,順便分享給大家,共同享受iOS所帶來的開發樂趣吧
示例demo:(ps:最后做分類模塊字體滑動有個陰影bug 有懂得大牛求幫忙解決感謝感謝)
網易新聞.gif
好咯,接下來就開始我的實現之路吧~
####第一步:環境的配置(cocoaPods安裝指南)
#安裝CocoaPods
### 查看當前的源
sudo gem sources -l
### 添加源
sudo gem sources -a https://ruby.taobao.org/
### 刪除源
sudo gem sources -r https://rubygems.org/
### 安裝
sudo gem install cocoapods
pod setup
***
#使用CocoaPods
### 搜索
pod search AFNetworking
### 生成 Podfile
echo "pod 'AFNetworking'" > Podfile
### 安裝
pod install
### 升級
pod update
由于本demo為抓包獲取網易新聞的JSON 我所采用的是第三方框架<AFN> 異步下載網絡圖片也是使用它自帶的UIImage的分類
-
第一步:自定義工具類獲取單例對象(繼承與AFHTTPSessionManager)
#import "HMNetworkTools.h"
@implementation HMNetworkTools
+ (instancetype)sharedNetworkTools{
static HMNetworkTools *instance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{NSURL *baseURL = [NSURL URLWithString:@"http://c.m.163.com/nc/"]; NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration]; //配置超時時長 config.timeoutIntervalForRequest = 30; instance = [[self alloc]initWithBaseURL:baseURL sessionConfiguration:config]; }); //設置轉換模式 instance.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html",@"text/json", @"text/javascript", nil]; return instance; } @end -
第二步:實現的就是圖片輪播器的那個效果
7866A03C-A4C9-48F3-A3A1-1BF86F8743F7.png
監聽網易新聞發送的HTTP請求,獲取請求數據的地址.根據獲取的數據創建圖片輪播器使用的模型類HeadLine
創建模型類,設置需要的屬性
封裝網絡操作
Controller中加載數據測試
自定義cell顯示圖片
#import <Foundation/Foundation.h>
@interface HMHeadLine : NSObject
//定義屬性
@property (nonatomic,copy)NSString *title;
@property (nonatomic,copy)NSString *imgsrc;
+ (instancetype)headlineWithDict:(NSDictionary *)dict;
//放松異步請求獲取數據
+ (void)headlineWithSucess:(void(^)(NSArray *array))sucess error:(void(^)())error;
@end
異步發送請求獲取模型對象
#import "HMHeadLine.h"
#import "HMNetworkTools.h"
@implementation HMHeadLine
+ (instancetype)headlineWithDict:(NSDictionary *)dict{
HMHeadLine *headline = [self new];
[headline setValuesForKeysWithDictionary:dict];
return headline;
}
- (void)setValue:(id)value forUndefinedKey:(NSString *)key{
}
//獲取數據
+ (void)headlineWithSucess:(void (^)(NSArray *))sucess error:(void (^)())error{
[[HMNetworkTools sharedNetworkTools] GET:@"ad/headline/0-4.html" parameters:nil success:^(NSURLSessionDataTask *task, NSDictionary *responseObject) {
//字典轉模型獲取數據
//獲取第一個KEY
NSString *rootKey = responseObject.keyEnumerator.nextObject;
NSArray *array = responseObject[rootKey];
NSMutableArray *marray = [NSMutableArray arrayWithCapacity:4];
//循環遍歷獲取模型
[array enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
HMHeadLine *model = [HMHeadLine headlineWithDict:obj];
[marray addObject:model];
}];
if (sucess) {
sucess(marray.copy);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (error) {
}
}];
}
@end
自定義cell
#import "HMHeadlineCell.h"
#import "HMHeadLine.h"
#import <UIImageView+AFNetworking.h>
@interface HMHeadlineCell ()
@property (weak, nonatomic) IBOutlet UIImageView *imgsrcView;
@property (weak, nonatomic) IBOutlet UILabel *titleView;
@property (weak, nonatomic) IBOutlet UIPageControl *pageControl;
@end
@implementation HMHeadlineCell
//從寫headline的方法
- (void)setHeadline:(HMHeadLine *)headline{
_headline = headline;
//解決重用問題
self.imgsrcView.image = nil;
self.titleView.text = nil;
//設置圖片
[self.imgsrcView setImageWithURL:[NSURL URLWithString:headline.imgsrc]];
//設置標題
self.titleView.text = headline.title;
self.pageControl.currentPage = self.tag;
}
@end
自定義CollectionViewControllView控制器實現數據源方法 加載數據實現圖片輪播器的效果
#import "HMImageLoopController.h"
#import "HMHeadLine.h"
#import "HMHeadlineCell.h"
@interface HMImageLoopController ()
@property (weak, nonatomic) IBOutlet UICollectionViewFlowLayout *flowLaout;
//當前圖片的索引
@property (nonatomic, assign) NSInteger currentIndex;
//聲明一個屬性
@property (nonatomic,strong)NSArray *array;
@end
@implementation HMImageLoopController
- (void)viewDidLoad {
[super viewDidLoad];
//設置背景顏色
self.collectionView.backgroundColor = [UIColor whiteColor];
[HMHeadLine headlineWithSucess:^(NSArray *array) {
self.array = array;
} error:^{
NSLog(@"請求數據失敗");
}];
[self setCollectionViewStyle];
}
#pragma mark - 刷新數據
- (void)setArray:(NSArray *)array{
_array = array;
[self.collectionView reloadData];
//永遠顯示第二個CELL
NSIndexPath *indexPath = [NSIndexPath indexPathForItem:1 inSection:0];
[self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:0 animated:NO];
}
- (void)viewDidLayoutSubviews{
[super viewDidLayoutSubviews];
//設置cell的大小
self.flowLaout.itemSize = self.collectionView.frame.size;
}
#pragma mark - 設置collectionView的樣式
- (void)setCollectionViewStyle{
//設置滾動方向
self.flowLaout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
self.flowLaout.minimumInteritemSpacing = 0;
self.flowLaout.minimumLineSpacing = 0;
self.collectionView.bounces = NO;
self.collectionView.pagingEnabled = YES;
self.collectionView.showsHorizontalScrollIndicator = NO;
}
#pragma mark - 數據源方法
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
return self.array.count;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
//創建cell
HMHeadlineCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"headline" forIndexPath:indexPath];
//在滾動過程中下一張圖片的索引
//當滾動的過程中item的值可能是 0 或者 2
NSInteger index = (self.currentIndex + indexPath.item - 1 + self.array.count) % self.array.count;
cell.backgroundColor = [UIColor whiteColor];
cell.headline = self.array[index];
cell.tag = index;
return cell;
}
//collectionView的代理方法
//滾動停止之后，把cell換成第二個cell
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView {
//計算下一張圖片的索引 (+1 -1)
//返回的值始終是 （0 2） - 1
int offset = scrollView.contentOffset.x / scrollView.bounds.size.width - 1;
self.currentIndex = (self.currentIndex + offset + self.array.count ) % self.array.count;
//始終顯示第二個cell
//主隊列的執行特點：先等待主線程上的代碼都執行完畢，再執行隊列中的任務
dispatch_async(dispatch_get_main_queue(), ^{
NSIndexPath *indexPath = [NSIndexPath indexPathForItem:1 inSection:0];
[self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:0 animated:NO];
});
}
@end
第三步:實現新聞列表模塊-實現數據的顯示及刷新數據(圖文混排效果,單圖,大圖,及三張圖片顯示的效果)
- 利用containerView 將圖片輪播器加載到一個自定義tabelView上形成聯動
news.png
同理- 創建新聞列表模型對象,發送異步請求獲取數據,自定義tabelViewControllerView控制器及自定義cell加載數據
- 創建模型
#import <Foundation/Foundation.h>
@interface HMNews : NSObject
//聲明屬性
@property (nonatomic,copy)NSString *imgsrc;
@property (nonatomic,copy)NSString *digest;
@property (nonatomic,copy)NSNumber *replyCount;
@property (nonatomic,copy)NSString *title;
//聲明一個大圖屬性
@property (nonatomic,assign)BOOL imgType;
//聲明三張圖的屬性
@property (nonatomic, copy) NSArray *imgextra;
//定義方法
+ (instancetype)newsWithDict:(NSDictionary *)dict;
//發送異步請求獲取數據
+ (void)newsWithurlString:(NSString *)urlString Sucess:(void(^)(NSArray *array))sucessBlock error:(void(^)())errorBlock;
@end
- 封裝并且回調實現異步發送請求獲取數據
#import "HMNews.h"
#import "HMNetworkTools.h"
@implementation HMNews
+ (instancetype)newsWithDict:(NSDictionary *)dict{
HMNews *news = [HMNews new];
[news setValuesForKeysWithDictionary:dict];
return news;
}
- (void)setValue:(id)value forUndefinedKey:(NSString *)key{
}
//發送異步請求獲取數據
+ (void)newsWithurlString:(NSString *)urlString Sucess:(void(^)(NSArray *array))sucessBlock error:(void(^)())errorBlock{
[[HMNetworkTools sharedNetworkTools] GET:urlString parameters:nil success:^(NSURLSessionDataTask *task, NSDictionary *responseObject) {
//獲取KEY
NSString *rootKey = responseObject.keyEnumerator.nextObject;
//獲取數組
NSArray *array = responseObject[rootKey];
NSMutableArray *mArray = [NSMutableArray arrayWithCapacity:10];
//遍歷數組獲取模型
[array enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
HMNews *model = [HMNews newsWithDict:obj];
[mArray addObject:model];
}];
if (sucessBlock) {
sucessBlock(mArray.copy);
}
} failure:^(NSURLSessionDataTask *task, NSError *error) {
if (errorBlock) {
errorBlock();
}
}];
}
@end
-
自定義cell 實現新聞列表中所要求格式的新聞詳情列表
#import <UIKit/UIKit.h> @class HMNews; @interface HMNewsCell : UITableViewCell //定義屬性屬性 @property (nonatomic,strong)HMNews *news; //判斷是否為大圖cell + (NSString *)getReuseId:(HMNews *)news; //判斷行高 + (CGFloat)getRowHeight:(HMNews *)news; @end -
實現自定義cell中的屬性賦值并且判斷圖片要求格式的要求進行圖片選擇
#import "HMNewsCell.h" #import "HMNews.h" #import <UIImageView+AFNetworking.h> @interface HMNewsCell () //聲明圖片,文字,摘要及回復數 @property (weak, nonatomic) IBOutlet UIImageView *imgsrcView; @property (weak, nonatomic) IBOutlet UILabel *titleView; @property (weak, nonatomic) IBOutlet UILabel *digestView; @property (weak, nonatomic) IBOutlet UILabel *replyCount; @property (strong, nonatomic) IBOutletCollection(UIImageView) NSArray *imgextraViews; @end @implementation HMNewsCell //從寫news的set方法進行賦值 - (void)setNews:(HMNews *)news{ _news = news; //獲取圖片,文字,摘要及回復數 [self.imgsrcView setImageWithURL:[NSURL URLWithString:news.imgsrc]]; self.titleView.text = news.title; self.digestView.text = news.digest; self.replyCount.text = [NSString stringWithFormat:@"回帖數:%d",news.replyCount.intValue]; //獲取數組中的照片 [news.imgextra enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { //獲取圖片的路徑 NSString *imgsrc = obj[@"imgsrc"]; UIImageView *imageView = self.imgextraViews[idx]; [imageView setImageWithURL:[NSURL URLWithString:imgsrc]]; }]; } //判斷是否為大圖cell + (NSString *)getReuseId:(HMNews *)news{ if (news.imgType) { //大圖 return @"news1"; }else if(news.imgextra){ //三張圖 return @"news2"; } return @"news"; } //判斷行高 + (CGFloat)getRowHeight:(HMNews *)news{ if (news.imgType) { //大圖 return 200; }else if (news.imgextra){ //三張圖 return 150; } return 80; } @end -
在自定義控制器中實現請求并且實現他的數據源方法 實現新聞列表的數據展示
#import "HMNewsController.h"
#import "HMNews.h"
#import "HMNewsCell.h"
@interface HMNewsController ()//定義一個屬性 @property (nonatomic,strong)NSArray *array; @end @implementation HMNewsController - (void)viewDidLoad { [super viewDidLoad]; } - (void)setUrlString:(NSString *)urlString{ //防止cell重用問題 self.array = nil; [HMNews newsWithurlString:urlString Sucess:^(NSArray *array) { //獲取數據 self.array = array; } error:^{ NSLog(@"出錯"); }]; } #pragma mark - 異步操作刷新數據 - (void)setArray:(NSArray *)array{ _array = array; [self.tableView reloadData]; } #pragma mark - 數據源方法 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return self.array.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //1.獲取數據 HMNews *news = self.array[indexPath.row]; //2.創建cell HMNewsCell *cell = [tableView dequeueReusableCellWithIdentifier:[HMNewsCell getReuseId:news]]; cell.news = news; return cell; } #pragma mark - 判斷cell的行高 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{ //1.獲取數據 HMNews *news = self.array[indexPath.row]; return [HMNewsCell getRowHeight:news]; } @end 第四部:(PS:也是最為困難的一步:至今雖然代碼敲出來了 但是還是覺得很暈這里面就涉及到了控制器之間的關聯又能顯示滾動翻頁又要實現分類之間的滑動最重要就是數據的分類刷新---希望有大牛能幫我解釋一番)
老樣子 現在要實現的是就是把之前寫的代碼都整合在一起放在一個自定義UIViewControllView中,設置根控制器為NavcontrollViewContrllView 在里面自控制器加入一個高度為44的scrollvIew及一個占下面的CollectView用來接受上面的兩個自定義類的數據 在根據JSON中的tname及tid 進行分類傳值刷新獲取不同新聞的列表 以及自定義的lbael的滾動.
在此-我會從寫創建一個StrobBord用來設置頁面到時候會從這里傳回數據
home.png
-
這里所需要的模型數據就是從網易新聞的抓包獲取的資源JSON用來管理不同新聞的分類.
#import <Foundation/Foundation.h> @interface HMChannel : NSObject //新聞的分類(頻道) @property (nonatomic,copy)NSString *tname; @property (nonatomic,copy)NSString *tid; //獲取請求數據網址 @property (nonatomic,copy,readonly)NSString *urlString; + (instancetype)channelWithDict:(NSDictionary *)dict; //返回數組懶加載 + (NSArray *)channelWithArray; @end -
懶加載數據獲取模型對象 并且實現網址的傳輸
#import "HMChannel.h"@implementation HMChannel + (instancetype)channelWithDict:(NSDictionary *)dict{ HMChannel *channel = [self new]; [channel setValuesForKeysWithDictionary:dict]; return channel; } - (void)setValue:(id)value forUndefinedKey:(NSString *)key{ } //返回數組懶加載 + (NSArray *)channelWithArray{ //從本地加載數據 NSString *path = [[NSBundle mainBundle] pathForResource:@"topic_news.json" ofType:nil]; NSData *data = [NSData dataWithContentsOfFile:path]; //JSON的反序列化 NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL]; NSArray *array = dict[@"tList"]; NSMutableArray *mArray = [NSMutableArray arrayWithCapacity:10]; //遍歷數據 字典轉模型 [array enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { HMChannel *model = [HMChannel channelWithDict:obj]; [mArray addObject:model]; }]; //對模型中的tid進行排序 return [mArray sortedArrayUsingComparator:^NSComparisonResult(HMChannel *obj1, HMChannel *obj2) { return [obj1.tid compare:obj2.tid]; }]; } //獲取網絡地址 - (NSString *)urlString{ return [NSString stringWithFormat:@"article/headline/%@/0-140.html",self.tid]; } @end 自定義cell 在collectionView中實現NEWS stroboard 添加view 實現他的數據源方法 從新獲取新聞數據
-
Home.storyboard中collectionView的每一個cell都要去加載News.storyboard中的view，所以創建自定義cell。
#import "HMHomeCell.h"
#import "HMNewsController.h"@interface HMHomeCell () @property (nonatomic,strong)HMNewsController *newsController; @end @implementation HMHomeCell //獲取數據 - (void)awakeFromNib{ //創建控制器加載View UIStoryboard *sb= [UIStoryboard storyboardWithName:@"News" bundle:nil]; self.newsController = [sb instantiateInitialViewController]; [self.contentView addSubview:self.newsController.view]; } //設置view的大小 - (void)layoutSubviews{ [super layoutSubviews]; self.newsController.view.frame = self.bounds; } - (void)setUrlString:(NSString *)urlString{ self.newsController.urlString = urlString; } @end -
自定義lbl實現 滾動分類的實現(并且實現新聞頻道的標簽的縮放及位置的變化)
#define kBIGFONT 18 #define kSMALLFONT 14 #import "HMChannelLabel.h" @implementation HMChannelLabel + (instancetype)channelLabelWithTName:(NSString *)tname{ HMChannelLabel *lbl = [self new]; lbl.text = tname; lbl.textAlignment = NSTextAlignmentCenter; //設置lbl大小 lbl.font = [UIFont systemFontOfSize:kBIGFONT]; [lbl sizeToFit]; //lbl默認大小 lbl.font = [UIFont systemFontOfSize:kSMALLFONT]; return lbl; } - (void)setScale:(CGFloat)scale{ CGFloat max = kBIGFONT * 1.0 / kSMALLFONT - 1; self.transform = CGAffineTransformMakeScale( max*scale+1, max*scale+1); self.textColor = [UIColor colorWithRed:scale green:0 blue:0 alpha:1]; } @end PS 最后一步 就是實現整個新聞的大致排版 也就是實現數據的加載跟lbl的創建及新聞頻道分類滾動實現(lbl計算涉及數學運算比較多~ 不作為本項目的重點)但是不知道lbl滾動為什么會有陰影的出現 有哪位大牛能夠看錯求忘能解決BUG,不勝感激.
