准备工作
注册appkey （抖音开放平台）
集成sharesdk（下载地址）
Xcode配置：urlScheme为注册的appkey, 白名单：douyinsharesdk ，douyinopensdk
业务代码
初始化

import <ShareSDK/ShareSDK.h>

[ShareSDK registPlatforms:^(SSDKRegister *platformsRegister) {

//抖音[platformsRegister setupDouyinByAppKey:@"app_key" appSecret:@"app_secret"];

}];
分享
可以分享图片，相册图片，单个视频，多个视频

分享图片

// 通用参数设置----图片分享可以使用相册地址、沙盒路径、网络图片地址
NSString *imageURL = @"http://img.hb.aicdn.com/28a4962c297205e0868cdb45bb527e2bc5319f08f019-l7N1A3_fw658";
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters SSDKSetupShareParamsByText:nil

                            images:@[imageURL]                               url:nil                             title:nil                              type:SSDKContentTypeImage];                              

[ShareSDK share:SSDKPlatformTypeDouyin parameters:shareParams onStateChanged:^(SSDKResponseState state, NSDictionary userData, SSDKContentEntity contentEntity, NSError *error) {

if (state == SSDKResponseStateSuccess) {    NSLog(@"成功！");}else{    NSLog(@"%@",error);}

}];
分享视频

// 通用参数设置----视频分享可以使用相册地址、沙盒路径，不支持网络视频，如果使用网络视频请先下载放到沙盒目录下或相册里

NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"cat" ofType:@"mp4"];NSMutableDictionary *parameters = [NSMutableDictionary dictionary];[parameters SSDKSetupShareParamsByText:nil                                images:nil                                   url:[NSURL URLWithString:videoPath]                                 title:nil                                  type:SSDKContentTypeVideo];                                  [ShareSDK share:SSDKPlatformTypeDouyin parameters:parameters onStateChanged:^(SSDKResponseState state, NSDictionary *userData, SSDKContentEntity *contentEntity, NSError *error) {    if (state == SSDKResponseStateSuccess) {        NSLog(@"成功！");    }else{        NSLog(@"%@",error);    }}];

分享多个视频

// 平台定制----只能使用相册且使用相册标识localIdentifier
