如何在Facebook上传/分享视频？
我正在制作测试应用程序，因为我想在Facebook上发布视频。我正在使用Facebook最新的sdk。但是我无法在Facebook上发布它。
我的代码如下。
NSDictionary *parameters = [NSDictionary dictionaryWithObject:videoData forKey:@"CareAppDemo.mov"];
FBRequest *request = [FBRequest requestWithGraphPath:@"me/videos" parameters:parameters HTTPMethod:@"POST"];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(@"result: %@, error: %@", result, error);
}];
请帮我通过我的应用在facebook上发布视频。

您需要先下载FacebookSDK 然后将以下框架添加到您的项目中
FacebookSDK.framework, FBSDKLoginKit.framework, FBSDKShareKit.framework, Bolts.framework,FBSDKCoreKit.framework
导入它们， 并写下以下代码
if(![FBSDKAccessToken currentAccessToken])
{
FBSDKLoginManager *login1 = [[FBSDKLoginManager alloc]init];
[login1 logInWithPublishPermissions:@[@"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoAssetURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;
[FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];
}];
}
else {
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = videoAssetURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;
[FBSDKShareDialog showFromViewController:self withContent:content delegate:nil];
}
视频网址videoURL必须是资产网址。您可以获取视频资产网址，例如来自UIImagePickerController。
或录制视频，您可以按照以下方式
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:[NSURL URLWithString:[[NSHomeDirectory() stringByAppendingPathComponent:@"Library/Caches"] stringByAppendingFormat:@"/current.mov"]] completionBlock:^(NSURL *assetURL, NSError *error)
{
videoAssetURL =assetURL;
}];

上成功测试
建议： .plist文件中的3个属性
设置FacebookAppID，FacebookDisplayName，
网址类型 - ＆gt;项目0-＆gt;网址方案设置为facebookappId前缀fb See
-(void)shareOnFaceBook
{
//sample_video.mov is the name of file
NSString *filePathOfVideo = [[NSBundle mainBundle] pathForResource:@"sample_video" ofType:@"mov"];

I GOT错误在App运行的第一次：
The operation couldn’t be completed. (com.facebook.sdk error 5.)
当facebook正在进行时就会发生这种情况。下次我打开我的应用程序，它工作正常，它始终是第一次。尝试了应用程序中的所有内容，但似乎是在Facebook SDK端。
看到com.facebook.sdk error 5的几个原因：
- 会话未公开。验证
- Facebook检测到您发送了垃圾邮件系统。更改视频名称。
- Facebook使用SDK定义了限制。尝试使用其他应用。
- 错误的发布权限。给
publish_actions一个旋转。 - 更多....

获取发布权限
NSArray* permissions = [[NSArray alloc] initWithObjects:
@"publish_stream", nil];
[facebook authorize:permissions delegate:self];
[permissions release];
试试这个
- (void)fbDidLogin {
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"mov"];
NSData *videoData = [NSData dataWithContentsOfFile:filePath];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
videoData, @"video.mov",
@"video/quicktime", @"contentType",
@"Video Test Title", @"title",
@"Video Test Description", @"description",
nil];
[facebook requestWithGraphPath:@"me/videos"
andParams:params
andHttpMethod:@"POST"
andDelegate:self];
}

这是旧线程，但对于所有未来的读者来说，这里是如何使用当前最新的facebook SDK（v3.24.0 - September 10th 2015）。
- (IBAction)bntShareOnFacebookAction:(id)sender {
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
[self shareVideoOnFacebook];
} else {
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logOut]; //very important line for login to work
[loginManager logInWithPublishPermissions:@[@"publish_actions"]
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if(!error) {
[self shareVideoOnFacebook];
}
}];
}
}
- (void) shareVideoOnFacebook {
NSString *videoPath = @"/Documents/.../movie.mov";
NSData *videoData = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:videoPath]];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:3L];
[params setObject:videoData forKey:@"video_filename.MOV"];
[params setObject:@"Title for this post." forKey:@"title"];
[params setObject:@"Description for this post." forKey:@"description"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/videos" parameters:params HTTPMethod:@"POST"]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
//video posted
}
}];
}

如果您要上传/视频共享，则必须为所选项目的原始版本传递资产库网址。
URL e.g assets-library://asset/asset.MOV?id=18BC70A0-208A-4F03-A207-7D57C8863425&ext=MOV
如果您正在使用
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
然后你必须要传递
NSURL *url = [info objectForKey:UIImagePickerControllerReferenceURL];
如果您使用文档目录路径，则首先需要将视频保存到库中。您必须创建URL链接资产库URL。
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:videoURL];
} completionHandler:^(BOOL success, NSError * _Nullable error) {
if (success) {
// Fetch Last saved video.
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:false]];
// Get video url.
PHAsset *fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeVideo options:fetchOptions].firstObject;
NSString *assetID = [fetchResult.localIdentifier substringToIndex:(fetchResult.localIdentifier.length - 7)];
NSURL *assetURL = [NSURL URLWithString:[NSString stringWithFormat:@"assets-library://asset/asset.MOV?id=%@&ext=MOV", assetID]];
// Share Video.
FBSDKShareVideo *video = [[FBSDKShareVideo alloc] init];
video.videoURL = assetURL;
FBSDKShareVideoContent *content = [[FBSDKShareVideoContent alloc] init];
content.video = video;
FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
shareDialog.shareContent = content;
shareDialog.delegate = (id)self;
shareDialog.fromViewController = self;
NSError * error = nil;
BOOL validation = [shareDialog validateWithError:&error];
if (validation) {
dispatch_async(dispatch_get_main_queue(), ^{
[shareDialog show];
});
} else {
NSLog(@"%@", error.localizedDescription);
}
}
}];
