使用钩子在 Instagram 上发布视频

Question

我希望我的应用能够将视频上传到 Instagram。

Instagram IPhone Hooks 提供了如何使用 iphone 挂钩将照片上传到 instagram 的信息。我的问题是，除了视频之外，是否有人对如何完成相同的操作有任何经验？

Answer 1

Instagram 的 API 不直接支持从第三方应用程序上传任何内容。因此，在向用户提供功能时，您必须在用户体验方面做出一些糟糕的妥协。

首先，准备好要上传到 Instagram 的视频并将其路径存储在某处

其次，将其保存到用户的相机胶卷中：

if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(filePath)) {
    UISaveVideoAtPathToSavedPhotosAlbum(filePath, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);
}

第三，既然视频已保存，请告诉用户为了将视频上传到他们的 Instagram，他们必须在点击上传按钮后从他们的相机胶卷中选择它。

上传按钮只需执行以下操作：

NSURL *instagramURL = [NSURL URLWithString:@"instagram://camera"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
    [[UIApplication sharedApplication] openURL:instagramURL];
}

Instagram API 不支持通过任何 API 端点立即选择媒体以用于上传目的，这非常愚蠢，但就目前而言，这是唯一的方法。

我有一个类似的问题：Instagram Video iPhone Hook 我想通了。有一个未记录的 iPhone 挂钩，可让您自动从 iPhone 相册中选择资产，并为视频预加载标题。这应该为您提供与 Flipagrams 应用程序在将视频分享到 Instagram 时相同的用户体验。

instagram://library?AssetPath=assets-library%3A%2F%2Fasset%2Fasset.mp4%3Fid%3D8864C466-A45C-4C48-B76F-E3C421711E9D%26ext%3Dmp4&InstagramCaption=Some%20Preloaded%20Caption

NSURL *videoFilePath = ...; // Your local path to the video
NSString *caption = @"Some Preloaded Caption";
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:[NSURL URLWithString:videoFilePath] completionBlock:^(NSURL *assetURL, NSError *error) {
    NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",[assetURL absoluteString].percentEscape,caption.percentEscape]];
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
        [[UIApplication sharedApplication] openURL:instagramURL];
    }
}];

尝试：

instagram://library?AssetPath=yourVideoPath

为 iOS 9 更新。

首先，对于 iOS9，您需要将其添加到您的 Info.plist 文件中。添加一个值为instagram 的键a LSApplicationQueriesSchemes。这会将 Instagram 计划列入白名单。 More info here.

这是基于 johnnyg17 的工作代码：

NSString *moviePath = @"<# /path/to/movie #>";
NSString *caption = @"<# Your caption #>";
NSURL *movieURL = [NSURL fileURLWithPath:moviePath isDirectory:NO];
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:movieURL
                            completionBlock:^(NSURL *assetURL, NSError *error)
{
    NSURL *instagramURL = [NSURL URLWithString:
                           [NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",
                            [[assetURL absoluteString] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet alphanumericCharacterSet]],
                            [caption stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet alphanumericCharacterSet]]]
                           ];
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
        [[UIApplication sharedApplication] openURL:instagramURL];
    }
    else {
        NSLog(@"Can't open Instagram");
    }
}];

一个示例 instagramURL 将是：

instagram://library?AssetPath=assets%2Dlibrary%3A%2F%2Fasset%2Fasset%2Emov%3Fid%3D69920271%2D2D44%2D4A84%2DA373%2D13602E8910B6%26ext%3Dmov&InstagramCaption=Super%20Selfie%20Dance%20%F0%9F%98%83

2016/5 更新：请注意，ALAssetsLibrary 现在已被弃用以保存到用户相册，现在推荐使用 Photos Framework。

这是在 Instagram 上分享视频的 swift 代码。

这里的videoURL是视频的资产url。

 func shareVideoToInstagram()
    {
        let videoURL : NSURL = "URL of video"

        let library = ALAssetsLibrary()
        library.writeVideoAtPathToSavedPhotosAlbum(videoURL) { (newURL, error) in

            let caption = "write your caption here..."

            let instagramString = "instagram://library?AssetPath=\((newURL.absoluteString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet()))!)&InstagramCaption=\((caption.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.alphanumericCharacterSet()))!)"

            let instagramURL = NSURL(string: instagramString)

            if UIApplication.sharedApplication().canOpenURL(instagramURL!)
            {
                UIApplication.sharedApplication().openURL(instagramURL!)
            }
            else
            {
                print("Instagram app not installed.")
            }                
        }
    }

确保您在 info.plist 中添加了以下代码：

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>instagram</string>
</array>

Instagram 已对此进行了更新，以使用更新的照片库。现在，您可以简单地传递相应的 PHAsset 的 localIdentifier，而不是传递图像/视频 URL：

PHAsset *first = /* Some PHAsset that you want to open Instagram to */;

NSURL *instagramURL = [NSURL URLWithString:[@"instagram://library?AssetPath=" stringByAppendingString:first.localIdentifier]];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
    [[UIApplication sharedApplication] openURL:instagramURL];
}

Answer 7

Instagram API 的上传功能极其有限，尤其是在视频文件方面。

据我了解，在将媒体上传到 Instagram 时，您基本上有两种选择。您可以使用 Document Interaction API 将图像传递给 Instagram 应用程序，或者您可以调用 Instagram 相机并要求用户从他们的相机胶卷中进行选择（如 Nico 所说）。

我很确定您只能通过文档交互系统将 JPEG 或 PNG 文件传递​​到 Instagram，因此对于视频，我相信您现在无法使用相机胶卷。这绝对不理想 - 我现在正在开发的应用程序使用 iPhone 挂钩，但我们决定坚持使用图片，直到 Instagram 改进他们的 API。

我使用了下面的代码，它对我有用。

` [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
            switch (status) {

                case PHAuthorizationStatusAuthorized: {

                            [MMProgressHUD showWithTitle:APPNAME status:@"Please wait..."];

                            _FinalVideoPath = [_FinalVideoPath stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];

                            NSURL *videoUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@", _FinalVideoPath]];

                                    // Write it to cache directory
                                    NSString *videoPath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"file.mov"];

你可以通过媒体端点来完成

https://api.instagram.com/v1/media/3?access_token=ACCESS-TOKEN

获取有关媒体对象的信息。返回的类型键将允许您区分图像和视频媒体。

http://instagram.com/developer/endpoints/media/

此链接用于获取图像媒体 ID。但我希望同样的技术对视频有所帮助。

Where do I find the Instagram media ID of a image

NSURL *instagramURL = [NSURL URLWithString:@"instagram://media?id=315"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
    [[UIApplication sharedApplication] openURL:instagramURL];
}

优势信息：

1. instagram://camera 将打开相机或照片库（取决于设备），
2. instagram://app 将打开应用程序
3. instagram://user?username=foo 将打开该用户名
4. instagram://location?id=1 将打开该位置
5. instagram://media?id=315 将打开该媒体
