UITextField * textField = [[UITextField alloc]initWithFrame:CGRectMake(30, 150, 260, 30)];

textField.borderStyle = UITextBorderStyleRoundedRect;

NSMutableAttributedString * attributedStr = [[NSMutableAttributedString alloc]initWithString:@"string"];

[attributedStr addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, attributedStr.length)];

textField.textAlignment = NSTextAlignmentCenter;

textField.attributedPlaceholder = attributedStr;

[self.view addSubview:textField];
