Remove temporary captured video produced by UIImagePickerController -

i use following codes capture video in uiimagepickerviewcontroller:

- (ibaction)openvideopicker:(id)sender {     self.video_picker = [[uiimagepickercontroller alloc] init];     self.video_picker.delegate = self;     self.video_picker.allowsediting = yes;     if ([uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypecamera])     {         self.video_picker.sourcetype = uiimagepickercontrollersourcetypecamera;         self.video_picker.mediatypes = [nsarray arraywithobjects:(nsstring *)kuttypemovie, nil];     }     else     {         self.video_picker.sourcetype = uiimagepickercontrollersourcetypephotolibrary;     }     [self presentviewcontroller:self.video_picker animated:yes completion:nil]; } 

when browse files in sand box, there lot of videos capture in /myapp/tmp/capture folder. since occupy quite lot amount of file size. when these temp files removed ? or can remove them manually via programming?

based on this comment can programmatically:

nsstring *videopath = @""; // path video nsfilemanager *filemanager = [nsfilemanager defaultmanager]; if ([filemanager fileexistsatpath: videopath]) {     nserror *error;     // attempt delete folder containing videopath     if ([filemanager removeitematpath: [videopath stringbydeletinglastpathcomponent] error: &error] != yes) {         nslog(@"unable delete file: %@", [error localizeddescription]);     } }
