在instagram上发布video使用钩子
我希望我的应用能够将video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，如果任何人有任何经验，如何做到这一点，但一个video？
Instagram的API不直接支持从第三方应用程序上传任何东西。 因此，在向用户提供function时，您必须做一些丑陋的用户体验妥协。
首先，准备要上传到Instagram的video并将其path存储到某处
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，现在保存了video，告诉用户，为了将video上传到他们的Instagram，他们必须在点击上传button之后从他们的相机胶卷中select它。
上传button只需执行以下操作：
NSURL *instagramURL = [NSURL URLWithString:@"instagram://camera"]; if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) { [[UIApplication sharedApplication] openURL:instagramURL]; }
非常愚蠢的是，Instagram API不支持通过任何API端点进行立即媒体select以进行上传，但是现在，这是唯一的方法。
我有一个类似的问题： Instagram的videoiPhone挂钩 ，我想通了。 有一个未公开的iPhone挂钩，允许您从iPhone照片卷中自动select资源，并为video预加载标题。 这应该给你相同的用户体验，Flipagram应用程序与Instagram分享video。
的Instagram：//库AssetPath =资产库％3A％2F％2Fasset％2Fasset.mp4％3Fid％3D8864C466-A45C-4C48-B76F-E3C421711E9D％26ext％3Dmp4＆InstagramCaption =有些％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]; } }];
尝试与：
instagram://library?AssetPath=yourVideoPath
我在这里find了解决办法： http : //blog.horizon.camera/post/102273431070/video-share-objc-ios-instagram
更新了iOS 9。
首先，对于iOS9，您需要添加到Info.plist文件中。 添加一个关键字LSApplicationQueriesSchemes的值为instagram 。 这将白名单的Instagram计划。 更多信息在这里。
这里是基于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"); } }];
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
更新2016/5：请注意，现在不推荐使用ALAssetsLibrary来保存到用户相册，现在已经build议使用相框。
Instagram API的上传function非常有限，特别是当涉及到video文件时。
据我所知，在上传媒体到Instagram时，基本上有两个select。 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select（如Nico所述）。
我很确定你只能通过文件交互系统将JPEG或PNG文件传递给Instagram，所以对于video我相信你现在已经停留在相机胶卷上了。 这绝对不是理想的 – 我现在正在使用的应用程序使用iPhone挂钩，但是我们决定坚持使用图像，直到Instagram改进其API。
这里是在Instagram上分享video的swift代码。
这里videoURL是video的资源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.") } } }
确保你在info.plist中添加了下面的代码：
<key>LSApplicationQueriesSchemes</key> <array> <string>instagram</string> </array>
Instagram更新了这个使用更新的照片库。 现在，您不必传递图片/videourl，只需传递相应的PHAsset的localIdentifier：
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]; }
我用下面的代码，它为我工作。
` [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) { switch (status) { case PHAuthorizationStatusAuthorized: { if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"instagram://"]]) { [MMProgressHUD setPresentationStyle:MMProgressHUDPresentationStyleExpand]; [MMProgressHUD showWithTitle:APPNAME status:@"Please wait..."]; _FinalVideoPath = [_FinalVideoPath stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]]; NSURL *videoUrl = [NSURL URLWithString:[NSString stringWithFormat:@"%@", _FinalVideoPath]]; dispatch_queue_t q = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul); dispatch_async(q, ^{ NSData *videoData = [NSData dataWithContentsOfURL:videoUrl]; dispatch_async(dispatch_get_main_queue(), ^{ // Write it to cache directory NSString *videoPath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"file.mov"]; [videoData writeToFile:videoPath atomically:YES]; [self createAlbumInPhotosLibrary:APPNAME videoAtFile:[NSURL fileURLWithPath:videoPath]ShareOnString:@"Instagram"]; }); }); } else { [MMProgressHUD dismiss]; [STMethod showAlert:self Title:APPNAME Message:@"Please install Instagram to share this video" ButtonTitle:@"Ok"]; } break; } case PHAuthorizationStatusRestricted: { [self PhotosDenied]; break; } case PHAuthorizationStatusDenied: { [self PhotosDenied];

NSError *removeError = nil; [[NSFileManager defaultManager] removeItemAtURL:[NSURL fileURLWithPath:videoPath] error:&removeError]; NSLog(@"%@",[removeError localizedDescription]); ZShareSuccessViewController *ShareView=[self.storyboard instantiateViewControllerWithIdentifier:@"ZShareSuccessViewController"];

} [MMProgressHUD dismiss]; NSLog(@"%@", error.localizedDescription); } }]; } `
您可以通过媒体结束点完成
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types键将允许您区分图像和video媒体。
http://instagram.com/developer/endpoints/media/
这里这个链接是为了获取图像媒体ID。 但我希望相同的技术将有助于video。
我在哪里可以find图片的Instagram媒体ID
NSURL *instagramURL = [NSURL URLWithString:@"instagram://media?id=315"]; if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) { [[UIApplication sharedApplication] openURL:instagramURL]; }
优势信息：
- instagram：//相机将打开相机或照片库（取决于设备），
- instagram：//应用程序将打开应用程序
- instagram：// user？username = foo将打开该用户名
- instagram：// location？id = 1将打开该位置
- instagram：// media？id = 315将打开该媒体
