###2017年2月9日 - 2017年2月13日

• 往夜资讯， 我从稍微简单的页面入手 -- 精华模块

• 整体为TableViewController， 里面分为三种Cell

  • 整体用masonry进行Layout布局
  • 界面整体比较简单， 其中Cell自适应高度， 我使用的UITableView-FDTemplateLayoutCell进行高性能自适应高度， 前百度forkingdog团队, 现在的滴滴打车的iOS大神Sunnyxx发布的高性能Cell自动高度计算框架.

//高性能计算行高
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    YGEssenceResponseFeedsItem *feedsItem = self.essenceArr[indexPath.section];
    if (feedsItem.type == 1) {
        return [tableView fd_heightForCellWithIdentifier:@"YGEssenceCommomCell" configuration:^(YGEssenceCommomCell *cell) {
            
            cell.iconIV.imageURL = feedsItem.image.yg_URL;
        }];
    }
    if (feedsItem.type == 0) {
        return [tableView fd_heightForCellWithIdentifier:@"YGEssenceImageCell" configuration:^(YGEssenceImageCell *cell) {
            [cell.iconIV setImageWithURL:feedsItem.image.yg_URL options:YYWebImageOptionIgnoreAnimatedImage];
        }];
    }
    
    return [tableView fd_heightForCellWithIdentifier:@"YGEssenceBigCell" configuration:^(YGEssenceBigCell *cell) {
        cell.titleLB.text = feedsItem.post.title;
        cell.detailLB.text = feedsItem.post.des;
        [cell.iconIV setImageWithURL:feedsItem.image.yg_URL options:YYWebImageOptionIgnoreAnimatedImage];
    }];
  
}

• 精华模块主要是资讯信息， 里面用到的是UIWebView来显示， 里面有一个退出按钮的小动画， 让我稍微琢磨了一小下。

#pragma mark - 创建悬浮按钮
- (void)creatSuspendButton
{
    self.suspendBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [self.suspendBtn setBackgroundImage:[UIImage imageNamed:@"homeBackButton"] forState:UIControlStateNormal];
    self.suspendBtn.frame = CGRectMake(0, 0, 54, 54);
    [self.suspendBtn addTarget:self action:@selector(clickSuspendButton) forControlEvents:UIControlEventTouchUpInside];
    //创建悬浮按钮的window
    self.buttonWin = [[UIView alloc] initWithFrame:CGRectMake(25, YGScreenH - 60, 54, 54)];
    self.buttonWin.backgroundColor = [UIColor clearColor];
    //将buttonWin显示出来
    [self.view addSubview:self.buttonWin];
    [self.buttonWin addSubview:self.suspendBtn];
    
    
}
//点击悬浮按钮
- (void)clickSuspendButton
{
    self.buttonWin.hidden = YES;
    self.buttonWin = nil;
    [self.navigationController popViewControllerAnimated:YES];
}

#pragma mark - viewWillAppear
- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    self.navigationController.navigationBarHidden = YES;
}
#pragma mark - viewViewDisappear
- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    self.navigationController.navigationBarHidden = NO;
}
//按钮隐藏
#pragma mark - <UIScrollViewDelegate>
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    
    if (scrollView.contentOffset.y > _offsetY + 1) {
        [self suspensionWithAlpha:0];
    }
    else if (scrollView.contentOffset.y < _offsetY)
    {
        [self suspensionWithAlpha:1];
    }
}

//停止滚动式调用
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    _offsetY = scrollView.contentOffset.y;
}

//设置悬浮按钮的透明度
- (void)suspensionWithAlpha:(CGFloat)alpha
{
    [UIView animateWithDuration:0.3 animations:^{
        [self.buttonWin setAlpha:alpha];
    }];
}

• 具体示例

###2017年2月14日 - 2017年2月15日

• 栏目模块结构

• 专题模块分为三次跳转

  • 第一个界面UICollectionViewController
  • 第二个界面UITableViewController
  • 第三个界面播放界面UIViewController

• 专题模块 和 列表详细整体masonry布局

• 列表详细播放中的播放我采用的是HcdCachePlayer

  • HcdCachePlayer对于整体播放， 缓存有着良好的集成

#import "YGListDetailMovieController.h"

@interface YGListDetailMovieController ()
{
    //播放器
    HcdCacheVideoPlayer *_play;
    
}
/** 背景 */
@property(nonatomic, strong) UIImageView *bgView;
/** 头像 */
@property(nonatomic, strong) UIImageView *headView;
/** 详细 */
@property(nonatomic, strong) UILabel *detailLb;
/** 影片简介 */
@property(nonatomic, strong) UILabel *constLabel;
/** 播放按钮 */
@property(nonatomic, strong) UIButton *playBtn;
// 计算属性, 屏幕大小
@property (nonatomic, assign) CGSize screenSize;

@end

@implementation YGListDetailMovieController

###2017年2月16日

• 开始往夜模块编写
• 插曲
  • 将Model层， View层全部写完， Controller层全部写完， 就差播放视频， 发现视频加密， 显示的全部垃圾广告。一晚白忙。此时凌晨3：35。

###2017年2月17日 - 2月19日

• 往夜 “往” 模块分为两种Cell

  • 一种Cell为资讯展示
  • 一种Cell为视频展示

• 往夜 “夜” 模块

• ”夜“模块

  • 第一个界面为TableviewController

• 点入”更多专题“为UICollectionViewController

• 点入专题详细列表， 表头为拉伸图片， 下面是tableview

• 更多专题中有显示图片的专题

  • 我用的是MWPhotoBrowser 这个框架

###2017年2月20日

• 收尾

##整体分析

• 项目主要以展示资讯，新闻，影视短片为主。
• 项目架构简约，整体色调灰黑色。
• 整个项目没有xib 或者 sb参与

##项目中细节梳理

• 头部无限轮播
• 使用iCarousel三方搭建。
  • 本来有考虑使用自己写的一个无限轮播 框架，但是我没有别的封装，仅仅只是实现了高性能轮播。所以我是用了 iCarousel三方搭建。

#pragma mark - <ic Delegate>
- (NSInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
    return self.loopArr.count;
}

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view
{
    if (!view) {
        view = [[UIView alloc] initWithFrame:carousel.bounds];
        UIImageView *iconIV = [[UIImageView alloc] init];
        [view addSubview:iconIV];
        [iconIV mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.left.right.offset(0);
            CGFloat scale = 38 / 64.0;
            make.height.mas_equalTo(iconIV.mas_width).multipliedBy(scale);
        }];
        iconIV.tag = 100;
    }
    YYAnimatedImageView *iconIV = [view viewWithTag:100];
    [iconIV setImageWithURL:[NSURL URLWithString:self.loopArr[index]] options:YYWebImageOptionIgnoreAnimatedImage];
    return view;
}
//只有变化时候才会来到这个方法
- (void)carouselCurrentItemIndexDidChange:(iCarousel *)carousel
{
    self.titleLb.text = self.bannersArr[carousel.currentItemIndex].post.title;
    self.pc.currentPage = carousel.currentItemIndex;
}

- (void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index
{
        YGEssenceWebController *webVC = [[YGEssenceWebController alloc] initWithAppView:self.bannersArr[index].post.appview];
        [self.navigationController pushViewController:webVC animated:YES];
}

- (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value
{
    if (option == iCarouselOptionWrap) {
        value = YES;
    }
    return value;
}

• “往夜”模块头部横向滚动
  • 使用的是一款WMPageController的三方控件

@interface YGPageController ()

@end

@implementation YGPageController

//初始化方法
- (instancetype)init
{
    if (self = [super init]) {
        self.menuBGColor = YGRGBColor(249, 249, 249);
        
        self.menuViewStyle = WMMenuViewStyleLine;
        self.menuViewLayoutMode = WMMenuViewLayoutModeCenter;
        self.titleSizeNormal = 20;
        self.titleSizeSelected = self.titleSizeNormal;
        
        self.titleColorSelected = self.titleColorNormal;
        self.automaticallyCalculatesItemWidths = YES; //根据题目的内容自动算宽度
        self.itemMargin = 30; //题目的间距
        self.menuHeight = 44;
        self.showOnNavigationBar = YES;
    }
    return self;
}

- (NSArray<NSString *> *)titles
{
    return @[@"往", @"夜"];
}


- (NSInteger)numbersOfChildControllersInPageController:(WMPageController *)pageController
{
    return self.titles.count;
}

- (UIViewController *)pageController:(WMPageController *)pageController viewControllerAtIndex:(NSInteger)index
{
    if (index == 0) {
        YGHomeController *homeVC = [[YGHomeController alloc] init];
        return homeVC;
    }
    YGCategoryController *cateVC = [[YGCategoryController alloc] init];
    return cateVC;
}
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
