Video not attached for mail when sharing video using UIActivityViewController - ios

Question

I am using the below code to share a video located on device, it works great for sharing via message, facebook and iCloud, only not for mail, I can see the mail option is there, but in the mail draft, the video is not attached.
In the code, videoAsset is a PHAsset of type PHAssetMediaTypeVideo.
[[PHImageManager defaultManager] requestAVAssetForVideo:videoAsset options:nil resultHandler:^(AVAsset *asset, AVAudioMix *audioMix, NSDictionary *info) {
AVURLAsset* urlAsset = (AVURLAsset*)asset;
fileUrl = urlAsset.URL;
NSLog(#"fileUrl is %#",fileUrl);
NSArray *activityItems = [NSArray arrayWithObjects:fileUrl, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];
}];
If I attach a video using UIImagePickerController, it works, I searched but couldn't find an answer, please help.

I ended up saving the video file to document directory, and using the file url from document directory, the video is attached for sharing via mail.
[[PHImageManager defaultManager] requestImageDataForAsset:videoAsset options:nil resultHandler:^(NSData *imageData, NSString *dataUTI, UIImageOrientation orientation, NSDictionary *info) {
NSLog(#"info is %#", info);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* videoPath = [documentsDirectory stringByAppendingPathComponent:#"IMG_2185.MOV"];
NSError *error;
[[NSFileManager defaultManager] removeItemAtPath:videoPath error:&error];
BOOL success = [imageData writeToFile:videoPath atomically:YES];
if (success) {
NSArray *activityItems = [NSArray arrayWithObjects:[NSURL fileURLWithPath:videoPath], nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];
}
}];
I also used requestExportSessionForVideo method to export a video to document directory, which also worked.
[[PHImageManager defaultManager] requestExportSessionForVideo:videoAsset options:nil exportPreset:AVAssetExportPresetPassthrough resultHandler:^(AVAssetExportSession *exportSession, NSDictionary *info) {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* videoPath = [documentsDirectory stringByAppendingPathComponent:#"test3.MOV"];
NSFileManager *manager = [NSFileManager defaultManager];
NSError *error;
if ([manager fileExistsAtPath:videoPath]) {
BOOL success = [manager removeItemAtPath:videoPath error:&error];
if (success) {
NSLog(#"I successfully removed it!");
}
}
NSURL *outputURL = [NSURL fileURLWithPath:videoPath];
NSLog(#"this is the final path %#",outputURL);
exportSession.outputFileType=AVFileTypeQuickTimeMovie;
exportSession.outputURL=outputURL;
[exportSession exportAsynchronouslyWithCompletionHandler:^{
if (exportSession.status == AVAssetExportSessionStatusFailed) {
NSLog(#"failed");
} else if(exportSession.status == AVAssetExportSessionStatusCompleted){
NSLog(#"completed!");
dispatch_async(dispatch_get_main_queue(), ^(void) {
NSArray *activityItems = [NSArray arrayWithObjects:outputURL, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityViewController animated:YES completion:nil];
//Main
});
}
}];
}];
