直接自定义一个类，继承UITextField, 里面书写

   [super awakeFromNib];
   //光标颜色
   self.tintColor = [UIColor whiteColor];
   NSDictionary *attrDict = @{
       NSForegroundColorAttributeName: [UIColor whiteColor]
   };
   self.attributedPlaceholder = [[NSAttributedString alloc]initWithString:self.placeholder attributes:attrDict];
}
