Question

Am developing a app which will upload video to the server which is picked form local iphone photo library.

here i want to restrict the user not to upload more than 3min of video..Question is how to get the duration of the video which is picked from local photo library using uiimagepickercontroller.

will it contain any property for that..?

Thanks

Answer 1

我不确定但你尝试过imagePickerController.videoMaximumDuration = urDuration;

Answer 2

您可以获得视频文件的大小。如果您想根据可能的大小进行检查，或者您可以通过使用mpmovieplayer类获得持续时间，但为此您必须获得完整的视频文件。我不这么认为你想要要做到这一点，如果你可以根据大小进行检查。
