Problems deleting video from document directory

问题

I am trying to delete a video from the document directory, but the video isn't deleting.

Here is how I am trying to delete the video:

//Delete Video
NSError *error = nil;
//NSData *videoData = [NSData dataWithContentsOfURL:self.finalURL];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/vid1.mp4"];
[[NSFileManager defaultManager] removeItemAtPath: tempPath error: &error];
UIAlertView *removeSuccessFulAlert=[[UIAlertView alloc]initWithTitle:@"Congratulation:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
[removeSuccessFulAlert show];

回答1:

You might get a good hint at your problem if you put in a line after your "removeItemAtPath" that says something like:

BOOL success = [[NSFileManager defaultManager] removeItemAtPath: tempPath error: &error];
if(!success)
{
    NSLog(@"error from removing item at path %@ is %@", 
        tempPath, [error localizedDescription]);   
} else {
    UIAlertView *removeSuccessFulAlert=[[UIAlertView alloc]initWithTitle:@"Congratulation:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
   [removeSuccessFulAlert show];
}

Try this instead:

NSString *tempPath = [documentsDirectory stringByAppendingPathComponent:@"vid1.mp4"];
