|
本文档为技术文档，需要阅读者：
|
|
|
|
|
|
|
|
* 具备基本的iOS开发能力
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
# 2.开发准备
|
|
|
|
|
|
|
|
## 2.1开发环境
|
|
|
|
|
|
|
|
* Xcode：苹果官方IDE
|
|
|
|
|
|
|
|
* iOS8+
|
|
|
|
|
|
|
|
## 2.2SDK使用说明
|
|
|
|
|
|
|
|
首先，需要下载最新版本的SDK，下载地址为：[VOD_iOS_DRM_SDK](https://github.com/CCVideo/VOD_iOS_DRM_SDK),然后导入SDK包到工程,在相应的地方引入头文件`#import "DWSDK.h"`
|
|
|
|
|
|
|
|
| 名称 | 描述 |
|
|
|
|
| :--------------------------------------- | :------- |
|
|
|
|
| Demo | 使用SDK对接CC视频云服务的示例源码 |
|
|
|
|
| doc | 存放的是iOS点播SDK开发指南及离线API |
|
|
|
|
| include | SDK开放的头文件及静态库 |
|
|
|
|
|
|
|
|
SDK实现了移动端在线离线播放、上传、下载的必要接口。使用这些接口时，需提供CC视频分配的userId和API KEY。你可以登陆[CC视频管理后台](http://admin.bokecc.com)获取。CC视频云使用userId和API KEY校验你的合法性，在使用SDK接口过程中，通常用它们作为模块初始化参数，填写错误或为空会造成失败。

# 3.快速集成
|
|
|
|
|
|
|
|
注：快速集成主要提供的是视频播放、上传、下载功能(核心功能)。
|
|
|
|
|
|
|
|
## 3.1播放快速集成
|
|
|
|
|
|
|
|
### 3.1.1在Appdelegate中添加AudioSession设置：
|
|
|
|
|
|
|
|
```
|
|
|
|
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
|
|
|
|
{
|
|
|
|
//设置全局AVAudioSession
|
|
|
|
NSError *categoryError = nil;
|
|
|
|
BOOL success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&categoryError];
|
|
|
|
if (!success)
|
|
|
|
{
|
|
|
|
NSLog(@"Error setting audio session category: %@", categoryError);
|
|
|
|
}
|
|
|
|
|
|
|
|
NSError *activeError = nil;
|
|
|
|
success = [[AVAudioSession sharedInstance] setActive:YES error:&activeError];
|
|
|
|
if (!success)
|
|
|
|
{
|
|
|
|
NSLog(@"Error setting audio session active: %@", activeError);
|
|
|
|
}
|
|
|
|
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
### 3.1.2创建播放器并展示在当前视图上
|
|
|
|
|
|
|
|
```
|
|
|
|
DWPlayerView *playerView = [[DWPlayerView alloc]initWithFrame:CGRectMake(0,0,ScreenWidth,ScreenHeight/2-50)];
|
|
|
|
//设置userID key
|
|
|
|
playerView.userId =USERID;
|
|
|
|
playerView.key =APIKEY;
|
|
|
|
//设置视频ID
|
|
|
|
playerView.videoId =@"xxxxxx";
|
|
|
|
//设置代理
|
|
|
|
playerView.delegate =self;
|
|
|
|
[self.view addSubview:playerView];
|
|
|
|
playerView.getPlayUrlsBlock = ^(NSDictionary *playUrls) {
|
|
|
|
//处理返回的播放信息字典
|
|
|
|
NSDictionary *dic =[[playUrls objectForKey:@"qualities"] firstObject];
|
|
|
|
NSURL *playURL =[NSURL URLWithString:[dic objectForKey:@"playurl"]];
|
|
|
|
//加载音视频资源
|
|
|
|
[playerView setURL:playURL withCustomId:nil];
|
|
|
|
//播放
|
|
|
|
[playerView play];
|
|
|
|
|
|
|
|
};
|
|
|
|
//请求播放信息
|
|
|
|
[playerView startRequestPlayInfo];
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
## 3.2上传快速集成
|
|
|
|
|
|
|
|
### 3.2.1初始化DWUploader
|
|
|
|
|
|
|
|
```
|
|
|
|
//videoTitle不得为空 videoPath音视频文件路径
|
|
|
|
DWUploader *uploader = [[DWUploader alloc] initWithuserId:USERID
|
|
|
|
andKey:APIKEY
|
|
|
|
uploadVideoTitle:videoTitle
|
|
|
|
videoDescription:videoDescripton
|
|
|
|
videoTag:videoTag
|
|
|
|
videoPath:videoPath
|
|
|
|
notifyURL:nil];
|
|
|
|
//进度的回调
|
|
|
|
uploader.progressBlock = ^(float progress, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
|
|
|
|
|
|
|
|
};
|
|
|
|
//上传成功的回调
|
|
|
|
uploader.finishBlock = ^() {
|
|
|
|
|
|
|
|
};
|
|
|
|
|
|
|
|
//上传失败的回调
|
|
|
|
uploader.failBlock = ^(NSError *error) {
|
|
|
|
|
|
|
|
};
|
|
|
|
//开始上传
|
|
|
|
[uploader start];
|
|
|
|
|
|
|
|
```
|
|
|
|
## 3.3下载快速集成
|
|
|
|
注：在项目TARGETS-Build Settings-Other linker Flags添加-ObjC 或者-all_load。-ObjC:链接静态库中所有的Objective-C代码到项目中，-all_load：链接静态库中所有的代码到项目中。
|
|
|
|
### 3.3.1在Appdelegate中进行后台下载设置
|
|
|
|
```
|
|
|
|
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
|
|
|
|
|
|
|
|
//后台下载设置
|
|
|
|
[[DWDownloadSessionManager manager] configureBackroundSession];//必须设置
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
### 3.3.2请求下载地址及初始化DWDownloadSessionManager
|
|
|
|
```
|
|
|
|
//hlsSupport必须传 @“0”
|
|
|
|
DWPlayInfo *playinfo = [[DWPlayInfo alloc] initWithUserId:USERID andVideoId:videoid key:APIKEY hlsSupport:@"0"];
|
|
|
|
//1为视频 2为音频 0为视频+音频 若不传该参数默认为视频
|
|
|
|
playinfo.mediatype =@"1";
|
|
|
|
[playinfo start];
|
|
|
|
//设置下载HTTP通信超时时间,默认超时时间为10秒,下载过程中HTTP通信超时时,会调用errorBlock下载失败的block,告知你请求资源超时。playinfo.timeoutSeconds = 20;
|
|
|
|
//请求下载资源成功 返回下载信息 调用DWUtils解析数据
|
|
|
|
playinfo.finishBlock = ^(NSDictionary *response){
|
|
|
|
//解析得到下载信息
|
|
|
|
NSDictionary *playUrls =[DWUtils parsePlayInfoResponse:response];
|
|
|
|
NSDictionary *dic =[[playUrls objectForKey:@"definitions"] firstObject];
|
|
|
|
//下载地址字符串
|
|
|
|
urlString =[dic objectForKey:@"playurl"];
|
|
|
|
}
|
|
|
|
DWDownloadSessionManager *manager =[DWDownloadSessionManager manager];
|
|
|
|
```
|
|
|
|
|
|
|
|
### 3.3.3初始化DWDownloadModel
|
|
|
|
```
|
|
|
|
//urlString：下载地址字符串 filePath:文件下载路径
|
|
|
|
DWDownloadModel *loadModel =[[DWDownloadModel alloc]initWithURLString:urlString filePath:filePath responseToken:nil userId:nil videoId:nil];
|
|
|
|
```
|
|
|
|
### 3.3.4开始下载
|
|
|
|
```
|
|
|
|
[manager startWithDownloadModel:loadModel progress:^(DWDownloadProgress *progress,DWDownloadModel *downloadModel) {
|
|
|
|
progress下载的进度 调用DWDownloadUtility 解析相关进度的信息
|
|
|
|
downloadModel 本次下载的downloadModel
|
|
|
|
|
|
|
|
} state:^(DWDownloadModel *downloadModel,DWDownloadState state, NSString *filePath, NSError *error) {
|
|
|
|
state 下载状态 如下几种
|
|
|
|
DWDownloadStateNone, // 未下载 或 下载删除了
|
|
|
|
DWDownloadStateReadying, // 等待下载
|
|
|
|
DWDownloadStateRunning, // 正在下载
|
|
|
|
DWDownloadStateSuspended, // 下载暂停
|
|
|
|
DWDownloadStateCompleted, // 下载完成
|
|
|
|
DWDownloadStateFailed // 下载失败
|
|
|
|
|
|
|
|
}];
|
|
|
|
```
|
|
|
|
### 3.3.5批量下载
|
|
|
|
```
|
|
|
|
//通过传入userId,key,vid数组，来获取所有vid的下载路径
|
|
|
|
DWBatchDownloadUtility * bdUtility = [[DWBatchDownloadUtility alloc]initWithUserId:DWACCOUNT_USERID key:DWACCOUNT_APIKEY AndVideoIds:videoIds];
|
|
|
|
bdUtility.finishBlock = ^(NSArray * _Nonnull playInfosArray) {
|
|
|
|
//返回获取到的vid下载路径
|
|
|
|
//具体使用方式，请详见demo
|
|
|
|
};
|
|
|
|
bdUtility.errorBlock = ^(NSError * _Nonnull error) {
|
|
|
|
|
|
|
|
};
|
|
|
|
|
|
|
|
[bdUtility start];
|
|
|
|
|
|
|
|
```
|
|
|
|

|
# 4.功能使用
|
|
|
|
|
|
|
|
## 4.1播放功能具体使用
|
|
|
|
|
|
|
|
### 4.1.1初始化playerView
|
|
|
|
```
|
|
|
|
DWPlayerView *playerView = [[DWPlayerView alloc] initWithframe:CGRectMake(0,0,ScreenWidth,ScreenHeight/2-50)];
|
|
|
|
// 设置请求播放信息HTTP通信超时时间
|
|
|
|
playerView.timeoutSeconds = 20;
|
|
|
|
//1为视频 2为音频 0为视频+音频 若不传该参数默认为视频
|
|
|
|
playerView.mediatype =@"0";
|
|
|
|
/**
|
|
|
|
设置填充模式 如果要自定义playerView的高，请先改变填充模式
|
|
|
|
AVPlayerLayer的videoGravity属性设置
|
|
|
|
AVLayerVideoGravityResize, // 非均匀模式。两个维度完全填充至整个视图区域
|
|
|
|
AVLayerVideoGravityResizeAspect, // 等比例填充，直到一个维度到达区域边界
|
|
|
|
AVLayerVideoGravityResizeAspectFill, // 等比例填充，直到填充满整个视图区域，其中一个维度的部分区域会被裁剪
|
|
|
|
填充模式默认为AVLayerVideoGravityResizeAspect
|
|
|
|
|
|
|
|
*/
|
|
|
|
playerView.videoGravity =AVLayerVideoGravityResizeAspect;
|
|
|
|
playerView.delegate =self;//设置代理
|
|
|
|
[self.view addSubview:playerView];//添加到目标视图
|
|
|
|
注：在播放过程中(譬如全屏 非全屏的切换等)不要移除playerView，否则会出现有声音无画面的bug
|
|
|
|
```
|
|
|
|
|
|
|
|
### 4.1.2getPlayUrlsBlock 获取视频播放信息
|
|
|
|
```
|
|
|
|
player.getPlayUrlsBlock = ^(NSDictionary *playUrls) {
|
|
|
|
// [必须]判断 status 的状态，不为"0"说明该视频不可播放，可能正处于转码、审核等状态。
|
|
|
|
NSNumber *status = [playUrls objectForKey:@"status"];
|
|
|
|
if (status == nil || [status integerValue] != 0) {
|
|
|
|
NSLog("playUrlsBlock invalid");
|
|
|
|
}
|
|
|
|
// 保存解析playUrls 或 选择某种清晰度进行播放。
|
|
|
|
};
|
|
|
|
```
|
|
|
|
当playerView准备好视频播放信息时，会调用该block。你可以在该block中保存播放信息或实现播放逻辑。获取的播放信息NSDictionary *playUrls为UTF-8编码，内容形如：
|
|
|
|
```
|
|
|
|
注意：若mediatype为@"0"，返回数据为视频+音频；若mediatype为@"1"，则只返回视频数据；若mediatype为@"2"，则只返回音频数据；若不设置mediatype，则只返回视频数据。以下以返回视频+音频为例：
|

对其字段解释如下：
|
|
|
|
```
|
|
|
|
- status（整数）和 statusinfo（字符串） status表示这个视频在CC视频云上的当前的状态值，statusinfo 是 状态值的文字描述，如正处于转码、正在审核等。只有当 status 为0时，该视频才可以播放。你在实现App播放逻辑时需特别注意。
|
|
|
|
- defaultquality（整数） 默认清晰度值
|
|
|
|
- qualityDescription（字符串数组） 清晰度及格式文字描述
|
|
|
|
- qualities（字典的列表） 不同清晰度播放url列表
|
|
|
|
- quality（整数）和 desp（字符串）清晰度数值和清晰度文字描述。
|
|
|
|
- playurl（字符串）音视频播放url
|
|
|
|
- spareurl (字符串)音视频播放url
|
|
|
|
- vrmode （整数）1表示当前视频是VR视频 0表示当前视频是普通视频
|

### 4.1.15播放VR视频
|
|
|
|
```
|
|
|
|
//播放普通视频流程一致 区别是普通视频是放在playerView上，而播放VR视频是可以放在自定义的view上
|
|
|
|
DWVRConfiguration* config = [DWVRLibrary createConfig];
|
|
|
|
[config asVideo:playerView.player.currentItem];//DWVideoPlayer的属性AVPlayer的currentItem
|
|
|
|
[config setContainer:self view:vrView]; //vrView自定义的视图
|
|
|
|
// optional
|
|
|
|
[config projectionMode:DWModeProjectionStereoSphere];//效果
|
|
|
|
[config displayMode:DWModeDisplayNormal];//是否分配
|
|
|
|
[config interactiveMode:DWModeInteractiveTouch];//交互模式
|
|
|
|
[config pinchEnabled:true];
|
|
|
|
[config setDirectorFactory:[[CustomDirectorFactory alloc]init]];
|
|
|
|
self.vrLibrary = [config build];
|
|
|
|
注意事项：1.如果playerView存在，则播放VR视频时必须隐藏，playerView.hidden =YES;
|
|
|
|
2.如果vrView存在，则播放普通视频时必须隐藏，vrView.hidden =YES;
|
|
|
|
3.播放VR视频时 切换资源时 先vrView =nil 再重新创建一次，然后调用切换资源的方法。
|
|
|
|
4.播放VR视频时，如果发现感应模式下的方向不正确，可调用{
|
|
|
|
[self.vrLibrary switchInteractiveMode:DWModeInteractiveTouch];
|
|
|
|
[self.vrLibrary switchInteractiveMode:DWModeInteractiveMotion];
|
|
|
|
}的组合方法来解决这个问题
|
|
|
|
5. DWModeInteractiveTouch,//触摸
|
|
|
|
DWModeInteractiveMotion,//重力感应
|
|
|
|
DWModeInteractiveMotionWithTouch,//触摸及重力感应
|
|
|
|
MotionWithTouch模式下时 触摸控制左右，重力感应控制上下
|
|
|
|
具体详情参见Demo。

### 4.1.16GIF功能
|
|
|
|
DWGIFManger可以将正在播放的视频做成GIF图，流程为：需要先截取视频 ，再将截取的视频转成GIF图。DWGIFManger开放的API如下：
|
|
|
|
```
|
|
|
|
/**
|
|
|
|
截取视频
|
|
|
|
@param videoUrl 视频的URL
|
|
|
|
@param outPath 输出路径
|
|
|
|
@param outputFileType 输出视频格式
|
|
|
|
@param videoRange 截取视频的范围
|
|
|
|
@param completeBlock 视频截取的回调
|
|
|
|
*/
|
|
|
|
- (void)interceptVideoAndVideoUrl:(NSURL *)videoUrl withOutPath:(NSString *)outPath outputFileType:(NSString *)outputFileType range:(NSRange)videoRange intercept:(InterceptBlock)interceptBlock;
|
|
|
|
|
|
|
|
|
|
|
|
/**
|
|
|
|
@param mediaUrlStr URL字符串
|
|
|
|
@return 返回视频时长
|
|
|
|
*/
|
|
|
|
- (CGFloat)getMediaDurationWithMediaUrl:(NSString *)mediaUrlStr;
|

|
|
|
@param time 每帧的时间间隔 默认0.25s
|
|
|
|

|
|
|
|
@param completeBlock 完成的回调
|
|
|
|
|
|
|
|
*/
|
|
|
|
- (void)createGIFfromURL:(NSURL*)videoURL loopCount:(int)loopCount delayTime:(CGFloat )time gifImagePath:(NSString *)imagePath complete:(CompleteBlock)completeBlock;
|
|
|
|
|
|
|

@param loopCount 播放次数
|
|
|
|
@param imagePath 存放GIF图片的文件路径

*/
|
|
|
|
- (void)createGIFfromURL:(NSURL*)videoURL withFrameCount:(int)frameCount delayTime:(CGFloat )time loopCount:(int)loopCount gifImagePath:(NSString *)imagePath complete:(CompleteBlock)completeBlock;
|
|
|
|
|
|
|
|
注意：1.截取视频前需要用获取截取视频的URL，加密SDK调用drmGIFURL方法，非加密SDK调用unDrmGIFURL方法
|
|
|
|
2.在视频将要结束播放的时候做GIF功能时，要计算截取视频的实际时长以及在播放完成的代理方法中暂停该视频，否则可能出现bug
|
|
|
|
以上API使用详情参见demo。
|
|

## 4.2上传功能具体使用
|
|
|
|
|
|
|
|
### 4.2.1初始化DWUploader
|
|
|
|
|
|
|
|
```
|
|
|
|
//首次上传视频 videoTitle不得为空
|
|
|
|
DWUploader *uploader = [[DWUploader alloc] initWithuserId:userId
|
|
|
|
andKey:apiKey
|
|
|
|
uploadVideoTitle:videoTitle
|

videoDescription:videoDescripton
|
|
|
|
videoTag:videoTag
|
|
|
|
videoPath:videoPath
|
|
|
|
notifyURL:nil];
|
|
|
|
//断点续传
|
|
|
|
DWUploader *uploader = [[DWUploader alloc] initWithVideoContext:dictionary];
|
|
|
|
// 默认超时时间为10秒,若上传过程中产生HTTP通信超时,则会调用DWErrorBlock,可以在该block设置错误处理逻辑。
|
|
|
|
uploader.timeoutSeconds = 20;
|
|
|
|
//设置代理
|
|
|
|
uploader.delegate =self;
|
|
|
|
```
|
|
|
|
### 4.2.2回调的block及代理方法
|
|
|
|
|
|
|
|
```
|
|
|
|
typedef void (^DWUploaderFinishBlock)();
|
|
|
|
typedef void (^DWErrorBlock)(NSError *error);
|
|
|
|
typedef void (^DWUploaderVideoContextForRetryBlock)(NSDictionary *videoContext);
|
|
|
|
typedef void (^DWUploaderProgressBlock)(float progress, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite);
|
|
|
|
|
|
|
|
/**
|
|
|
|
* 在该block获取上传进度，可以在block内更新UI，如更新上传进度条。
|
|
|

*/
|
|
|
|
@property (copy, nonatomic)DWUploaderProgressBlock progressBlock;
|
|
|
|
|
|
|
|
/**
|
|

/**

|
|

|
|
|
|
*/
|
|
|

@property (copy, nonatomic)DWErrorBlock pausedBlock;
|
|
|
|
|
|
|
|
/*
|
|

|
|
@protocol DWUploaderDelegate <NSObject>
|
|
|
|
@optional
|
|
|
|
//第一次请求成功的回调
|
|
|
|
- (void)checkUploadWithFilePath:(NSString *)filePath;
|
|
|
|
|
|
|
|
@end
|
|
|
|
|
|
|
|
注：通常情况下，不可对同一视频多次使用第一种初始化方式初始化上传，这样会造成大量重复视频，增加你后期管理视频的同事的工作量，且CC视频会根据你的付费套餐对每天的上传次数有不同的限制，超过最大上传次数，当天便无法上传视频。
|
|
|
|
```
|
|
|
|
### 4.2.3暂停
|
|
|
|
```
|
|
|
|
[uploader pause];
|
|
|
|
```
|
|
|
|
### 4.2.4恢复上传
|
|
|
|
```
|
|
|
|
[uploader resume];
|
|
|
|
```
|
|
|
|
### 4.2.5视频压缩
|
|
|
|
```
|
|
|
|
//初始化 DWVideoCompressController
|
|
|
|
DWVideoCompressController *imagePicker = [[DWVideoCompressController alloc] initWithQuality:DWUIImagePickerControllerQualityTypeMediumandSourceType:DWUIImagePickerControllerSourceTypePhotoLibraryandMediaType:DWUIImagePickerControllerMediaTypeMovie];
|
|
|
|
|
|
|
|
//设置delegate
|
|
|
|
imagePicker.delegate = self;
|
|
|
|
注：CC视频的压缩是继承UIImagePickerController，你需要实现UIImagePickerControllerDelegate的回调来处理媒体压缩的后续功能。如果设置相关属性时可以直接用DWVideoCompressController对象修改。
|
|
|
|
|
|
|
|
//设置媒体压缩质量
|
|
|
|
typedef NS_ENUM(NSInteger, DWUIImagePickerControllerQualityType) {
|
|
|
|
DWUIImagePickerControllerQualityTypeHigh = 0,
|
|
|
|
DWUIImagePickerControllerQualityTypeMedium = 1,
|
|
|
|
DWUIImagePickerControllerQualityTypeLow = 2,
|
|
|
|
};
|
|
|
|
|
|
|
|
//设置媒体来源
|
|
|
|
typedef NS_ENUM(NSInteger, DWUIImagePickerControllerSourceType) {
|
|
|
|
DWUIImagePickerControllerSourceTypePhotoLibrary, DWUIImagePickerControllerSourceTypeCamera, DWUIImagePickerControllerSourceTypeSavedPhotosAlbum
|
|
|
|
};
|
|
|
|
|
|
|
|
//设置媒体类型
|
|
|
|
typedef NS_ENUM(NSInteger, DWUIImagePickerControllerMediaType) {
|
|
|
|
DWUIImagePickerControllerMediaTypeMovieAndImage,
|
|
|
|
DWUIImagePickerControllerMediaTypeMovie,
|
|
|
|
DWUIImagePickerControllerMediaTypeImage
|
|
|
|
};
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
## 4.3下载功能具体使用
|
|
|
|
注：在项目TARGETS-Build Settings-Other linker Flags添加-ObjC 或者-all_load。-ObjC:链接静态库中所有的Objective-C代码到项目中，-all_load：链接静态库中所有的代码到项目中。
|
|
|
|
### 4.3.1获取下载地址
|
|
|
|
|
|
|
|
```
|
|
|
|
//hlsSupport必须传 @“0”
|
|
|
|
DWPlayInfo *playinfo = [[DWPlayInfo alloc] initWithUserId:DWACCOUNT_USERID andVideoId:videoid key:DWACCOUNT_APIKEY hlsSupport:@"0"];
|
|
|
|
//1为视频 2为音频 0为视频+音频 若不传该参数默认为视频
|
|
|
|
playinfo.mediatype =@"1";
|
|
|
|
[playinfo start];
|
|
|
|
//设置下载HTTP通信超时时间,默认超时时间为10秒,下载过程中HTTP通信超时时,会调用errorBlock下载失败的block,告知你请求资源超时。playinfo.timeoutSeconds = 20;
|
|
|
|
//回调的block
|
|
|
|
@property (copy, nonatomic)DWErrorBlock errorBlock;
|
|
|
|
@property (copy, nonatomic)DWPlayInfoFinishBlock finishBlock;
|
|
|
|
|
|
|
|
请求下载资源成功 返回下载信息 调用DWUtils解析数据
|
|
|
|
playinfo.finishBlock = ^(NSDictionary *response){
|
|
|
|
|
|
|
|
NSDictionary *playUrls =[DWUtils parsePlayInfoResponse:response];
|
|
|
|
|
|
|
|
}
|
|
|
|

注：下载的URL的时效是两小时。两小时后URL失效，可根据开放的API做断点续传。因为iOS11.3后的系统bug，目前在11.3后的系统中无法做URL失效后的断点续传功能，代码中也要相应增加系统版本判断，详情参见demo。

|
|
|
|
## 4.4Demo具体使用
|
|
|
|
Demo是使用SDK对接CC视频云的示例源码，Demo的设计旨在展示SDK各项功能的使用方法，如果希望应用获得更好的使用体验，要根据需求自行更改。Demo使用流程如下：
|
|
|
|
|
|
|
|
## 4.4.1设置账户信息
|
|
|
|
首先将你userId和API KEY填写在Demo工程下的Demo-Prefix.pch 中:
|
|
|
|
```
|
|
|
|
#define USERID @"****************"
|
|
|
|
#define APIKEY @"********************************"
|
|
|
|
```
|
|
|
|
## 4.4.2设置播放使用的videoId
|
|
|
|
在DWPlayerViewController.m中修改generateTestData函数：
|
|
|
|
```
|
|
|
|
- (void)generateTestData
|
|
|
|
{
|
|
|
|
// 将@"..."替换成你要播放的videoId，可以添加多个。
|
|
|
|
self.videoIds = @[];
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
## 4.4.3设置下载使用的videoId
|
|
|
|
需要在DWDownloadViewController.m中修改generateTestData函数：
|
|
|
|
|
|
|
|
```
|
|
|
|
- (void)generateTestData
|
|
|
|
{
|
|
|
|
// 将@"..."替换成你要下载的videoId，可以添加多个。
|
|
|
|
self.videoIds = @[];
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
Demo配置完毕,可以使用Demo测试你的账号。
|
|
|
|
|
|
|
|
## 4.4.4如何调试和反馈问题
|
|
|
|
SDK提供了DWLog模块用来打印HTTP通信日志，可以在App的任意位置开启或关闭 打印HTTP通信日志等功能。下面是DWLog的使用方法：
|
|
|
|
|
|
|
|
```
|
|
|
|
// 开启 打印HTTP通信日志 功能
|
|
|
|
[DWLog setIsDebugHttpLog:YES];
|
|
|
|
// 关闭 打印HTTP通信日志 功能
|
|
|
|
[DWLog setIsDebugHttpLog:NO];
|
|
|
|
```
|
|
|
|
当遇到无法播放、上传或下载时，首先要排除userId和API KEY是否有效，其次判断网络是否正常、是否已经连接、 videoId是否是userId和API KEY名下的视频。除此之外还可以通过 HTTP通信日志排查问题。
|
|
|
|
|
|
|
|
## 4.4.5关于错误码
|
|
|
|
|
|
|
