我希望我的应用能够将视频上传到Instagram。

Instagram IPhone Hooks提供有关如何使用iphone挂钩将照片上传到instagram的信息。我的问题是，如果有人有任何经验，如何完成相同但视频？

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，您必须做出一些丑陋的用户体验妥协。

首先，准备要上传到Instagram的视频并将路径存储到某个地方

其次，将其保存到用户的相机胶卷：

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

第三，既然保存了视频，告诉用户为了将视频上传到Instagram，他们必须在点击上传按钮后从相机胶卷中选择它。

上传按钮只会执行以下操作：

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端点立即选择媒体进行上传，这是非常愚蠢的，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我想出来了。有一个未记录的iPhone挂钩，允许您从iPhone照片卷自动选择资源，并预加载视频的标题。这应该为您提供Flipagrams应用程序与Instagram共享视频时的相同用户体验。

尝试：

instagram://library?AssetPath=yourVideoPath

针对iOS 9进行了更新。

首先，对于iOS9，您需要添加到Info.plist文件中。添加值为LSApplicationQueriesSchemes的{​​{1}}密钥。这将使Instagram计划列入白名单。 More info here.

以下是基于johnnyg17＆＃39的工作代码：

instagram

样本instagramURL将是：

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"); } }];

更新2016/5 ：请注意，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现已弃用以保存到用户相册，现在推荐Photos Framework。

以下是Instagram上分享视频的快捷代码。

这里videoURL是视频的资产网址。

 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已将此更新为使用较新的照片库。现在，您可以简单地传递相应的PHAsset的localIdentifier，而不是传递图像/视频网址：

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];
}

Instagram API的上传功能非常有限，特别是在视频文件方面。

据我所知，在将媒体上传到Instagram时，您基本上有两种选择。您可以使用文档交互API将图像传递到Instagram应用程序，也可以调用Instagram相机并要求用户从他们的相机胶卷中进行选择（如Nico所述）。

我很确定你只能通过文档交互系统将JPEG或PNG文件传递给Instagram，所以对于视频我相信你现在一直坚持使用相机胶卷。这绝对不是理想的 - 我正在使用的应用程序现在使用iPhone挂钩，但我们决定坚持使用图像，直到Instagram改进他们的API。

你可以通过媒体终点来完成

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/

此链接用于获取图片媒体ID。但我希望同样的技术可以在视频中提供帮助。

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：//相机将打开相机或照片库（取决于设备），
  2. instagram：//应用将打开应用
  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
