NSInvalidArgumentException – App terminates while i'm trying to copy a captured video to documents folder

I'd like to try the wisdom of the crowds..because i'm frustrated right now. Thanks in advance.

So here is my code:

- (void)imagePickerController:(UIImagePickerController *)ipc didFinishPickingMediaWithInfo:(NSDictionary *)info{

NSLog(@"info: %@",info);

NSString *newFilename = [NSString stringWithFormat:@"%@/%@.mov", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"], [NSString stringWithFormat:@"%d", (long)[[NSDate date] timeIntervalSince1970]]];

N开发者_运维知识库SLog(@"newFilename: %@",newFilename);

NSFileManager *filemgr = [NSFileManager defaultManager];

NSError *err; if ([filemgr copyItemAtPath:[info objectForKey:@"UIImagePickerControllerMediaURL"] toPath:newFilename error:&err] == YES) NSLog (@"Move successful"); else NSLog (@"Move failed");

and this is the log:

 2010-05-16 18:19:01.975 erlkoenig[7099:307] info: {
    UIImagePickerControllerMediaType = "public.movie";

   }
newFilename: /var/mobile/Applications/BE25F9B5-2D08-4B59-8B62-D04DF7BB7E5B/Documents/1274026741.mov

I can follow you logic but have one fundamental issue: this is not how you save video.

Please see a rough example below without the relevant error checking.

(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

    .... code here .....

    NSString* videoURL= [info objectForKey:UIImagePickerControllerMediaURL];

    //remember to test that the video is compatible for saving to the photos album

    UISaveVideoAtPathToSavedPhotosAlbum(videoURL, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);

    .... code here .....

}
