在我的应用中,我需要将视频上传到用户的脸书墙。我使用这段代码并且有效:
[FBRequestConnection startWithGraphPath:@"me/videos"
parameters:params
HTTPMethod:@"POST"
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
if (error)
{
//showing an alert for failure
}
else
{
//showing an alert for success
}
}];
我想在上传时添加一个进度条......但是我找不到任何有用的东西......我也读过文档,但我找不到任何东西......那里是一种管理@" me / videos"的进度条的方法。 ?

您可以在FBRequestConnection上设置FBRequestConnectionDelegate,请参阅https://developers.facebook.com/docs/reference/ios/current/protocol/FBRequestConnectionDelegate/,并实现requestConnection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite方法。
您的进度应为totalBytesWritten / totalBytesExpectedToWrite。
如果要设置委托,还需要单独创建FBRequest和FBRequestConnection,如:
FBRequest *request = [FBRequest requestForUploadVideo:@"some_path"];
FBRequestConnection *connection = [[FBRequestConnection alloc] init];
[connection addRequest:request completionHandler:YOUR_HANDLER_HERE];
connection.delegate = self;
[connection start];
