Captured Video on iPhone, trying to move it to another directory

Using UIImagePickerController, I have captured a video. When I call [picker stopVideoCapture], then the following delegate method is called:

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

    NSURL *url = [info objectForKey:UIImagePickerControllerMediaURL];

    NSError *error = nil;

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [paths objectAtIndex:0];

    NSFileManager *fileManager = [[NSFileManager alloc] init];

    NSLog(@"attempting to copy: %@ to: %@", [url absoluteString], [NSString stringWithFormat:@"%@/rawMovie.MOV",path]);


if ([fileManager moveItemAtPath:[url absoluteString] toPath:[NSString stringWithFormat:@"%@/rawMovie.MOV",path] error:&error] != YES)
    NSLog(@"Can't move file with error: %@", [error localizedDescription]);

}

When this method is called however, it returns an error reading:

The operation couldn’t be completed. (Cocoa error 4.)

As far as I have been able to tell, this means that the file cannot be copied for some unknown reason. Can anyone give me a better answer as to why this error is being thrown? Or, better yet, can anyone tell me the best way to save the captured video di开发者_运维知识库rectly to the app's documents directory?

Thanks, James

Why dont you put breakpoints & see the output of *path and url. Also do you have enough disk space to store your video on the device?

I think you need to use the default file manager:

NSFileManager* fileManager = [NSFileManager defaultManager];

You can also log the error's userinfo for (hopefully) more details.

NSLog(@"Can't move file with error: %@", [error userInfo]);
