NSString *holderText = @"请输入密码!";NSMutableAttributedString *placeholder = [[NSMutableAttributedString alloc] initWithString:holderText];[placeholder addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, holderText.length)];[placeholder addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:16] range:NSMakeRange(0, holderText.length)];textField.attributedPlaceholder = placeholder;[cell.contentView addSubview:textField];
