Autolayout constraints conflict

Trying to create a view with a `UITextField` and `UILabel` beyond it. What's wrong with the following code? ``` - (UIView *)tableHeaderView{ NSArray *constraints; UIView *view = [[UIView alloc]initWithFrame:(CGRect){0,0,self.view.frame.size.width, 88}]; UITextField *tf = [[UITextField alloc]init]; tf.borderStyle = UITextBorderStyleRoundedRect; tf.text = _filter.name; [view addSubview:tf]; UILabel *titleLabel = [[UILabel alloc] init]; titleLabel.textAlignment = NSTextAlignmentCenter; titleLabel.translatesAutoresizingMaskIntoConstraints = NO; titleLabel.text = [NSString stringWithFormat:NSLocalizedString(@"Found results: %d", nil), _filter.resultsCount]; [view addSubview:titleLabel]; constraints = [NSLayoutConstraint constraintsWithVisualFormat:@"|-[titleLabel]-|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(titleLabel)]; [view addConstraints:constraints]; constraints = [NSLayoutConstraint constraintsWithVisualFormat:@"|-[tf]-|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(tf)]; [view addConstraints:constraints]; constraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|[titleLabel]-8-[tf]|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(titleLabel, tf)]; [view addConstraints:constraints]; } ``` Error message: ``` Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it.
