Question

在为iPhone做app时，我的Xcode编译器出现了一个奇怪的错误。我得到的错误是：

Expected ']'

- (IBAction)backButton:(id)sender
{
    NSUserDefaults* standardUserDefaults = [NSUserDefaults standardUserDefaults];
    if(standardUserDefaults)
    {
        NSString* isNewNote = [standardUserDefaults objectForKey:@"newNote"]; // here is the error
        if(isNewNote isEqualToString:@"Yes")
        {
            [noteList removeObjectAtIndex:currentNote];
            [noteContent removeObjectAtIndex:currentNote];
        }
    }

    NSString* storyboardName = @"Main";
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
    [self presentViewController:vc animated:NO completion:nil];
}

你能搞清楚什么是错的吗？感谢。

此：

if(isNewNote isEqualToString:@"Yes")

应该是这样的：

if([isNewNote isEqualToString:@"Yes"])
