iOS 数据存储 NSData存储转为NSDictionary存储

发表于 2025-06-19 分类于技术

最近做app，涉及到关于数据的存储，对于远程数据的请求，有个问题就是，对于同样的请求，不做重复的操作，但是又能够保证，获取的数据在本地，并且即使的进行解析，之前是NSdata，这样的话，转换数据的话，就要涉及到一个中间步骤，就是将数据转换为json格式，在转换为NSdictionary，解析的过程会出现的可能性，导致数据不能及时响应，最近几次的闪退，估计是这个原因，于是做了调整，闪退的现象果然概率不再频繁。

这次主要是分享一下，修改后的封装类，主要是在里面添加了几个关于存储NSDictionary的方法

vim Gvim MACVim 真的分屏操作

发表于 2025-06-18 分类于技术

如何横/竖分屏打开新文件

:sp filename
:split filename
:vsp filename
:vsplit filename
:sview filename  ->只读分屏打开文件

从命令行直接打开多个文件且是分屏

1 2	vim -On file1, file2 ... ->垂直分屏 vim -on file1, file2 ... ->水平分屏

其中n为分几个屏

如何横/竖分屏打开当前文件

1 2	ctrl+W s ctrl+W v

如何切换分屏

1
2
3

ctrl+w w
ctrl+w h,j,k,l
ctrl+w 上下左右键头

如何关闭分屏

ctrl+W c 关闭当前窗口
ctrl+w q 关闭当前窗口，若只有一个分屏且退出vim
:only  仅保留当前分屏
:hide  关闭当前分屏

如何调整分屏的大小

ctrl+w = 所有分屏都统一高度
ctrl+w + 增加高度
ctrl+w - 减少高度
10 ctrl+w + 增加10行高度

如何移动分屏

1	ctrl+W H,J,K,L

7.多标签

多个标签间进行切换时向右切换gt，向左切换用gT

在编辑的时候想增加一个标签就可以:tabnew filename

:tabc       关闭当前的tab

:tabo       关闭所有其他的tab

:tabs       查看所有打开的tab

:tabp      前一个

:tabn      后一个

第二个是，据说是最全的一个，也是最好的一个，不过我没有使用，我用了第一个后感觉第一个可以复制命令，第二个就没有了，看来里面还是有区别的，抽时间看看

还有一个是使用命令行安装的，呵呵我不怎么喜欢这样的，不过还是贴到下面，给喜欢的朋友们

1	sudo apt-get install vim-scripts

然后想安装什么插件都可以输入以下命令：

vim-addons install taglist   
vim-addons install supertab
vim-addons install cscope
vim-addons install winmanager
vim-addons install tags

然后修改相应的配置就行了，如果找不到～/.vimrc可以在vi /etc/vim/vimrc中修改

滚动条下拉自动加载内容

发表于 2025-06-18 分类于技术

先来看看代码：

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" type="text/javascript"></script>

   <script type="text/javascript">
    $(document).ready(function(){
        var range = 50;             //距下边界长度/单位px
        var elemt = 500;           //插入元素高度/单位px
        var maxnum = 3;            //设置加载最多次数
        var num = 0;
        $(window).scroll(function(){
            var srollPos = $(window).scrollTop();    //滚动条距顶部距离(页面超出窗口的高度)
            var dbHiht = $("body").height();          //页面(约等于窗体)高度/单位px
            var main = $("#try");                         //主体元素
            var mainHiht = main.height();               //主体元素高度/单位px

            if((srollPos + dbHiht) >= (mainHiht-range) && num != maxnum){
                main.append("<div style='height:"+elemt+"' >hello world"+srollPos+"---"+num+"</div>");
                num++;
            }
        });
    });
    </script>
</head>
<body>
    <div id="try" style="height:960px">
        <div id="follow">this is a scroll test;<br/>    页面下拉自动加载内容</div>
    </div>
</body>
</html>

原理很简单，通过注释可以很清楚是怎么实现的。

有人评论说

把偏移再加70将达到更好的滚动到底部再加载的效果。如下：(srollPos + dbHiht) >= (mainHiht-range+70)

自定义UITableViewCell（使用xib文件），还可以自定义处理选中按钮和非选中按钮

发表于 2025-06-18 分类于技术

最近在做自定义的cell的操作，由于之前是在网上找的一个类似的东东，结果拿来用的时候就出现了很多的问题，呵呵，结果我还是自己研究了一下，原因就是我之前是使用自定义的cell的问题是，在删除和非删除的过程中进行切换，有个选中和非选中的图片总是迟一步退去，导致的问题是，挡住了后面的内容，‍使得整个看起来不美观，结果我就是使用了UIImageView的隐藏功能，代码我放在下面，github也有的。在使用的时候最好是参照我的另一片博文：IPhone 自定义 UITableViewCell 行缩进（修正版）。好了，看代码。

自定义UITableViewCell 不使用xib文件

发表于 2025-06-18 分类于技术

以前经常使用xib做自定义的UITableViewCell，但是最近因为老是闪退，于是想知道是不是因为xib的问题，因为之前意识到一个问题就是兼容的问题，这里涉及到一个AutoLayout的问题。于是想不用xib文件试试。

代码：

NSString *personImagePath = [[NSBundle mainBundle] pathForResource:@"Icon_NMI" ofType:@"png"];
UIImageView *personView = [[UIImageView alloc] initWithImage:[[UIImage alloc] initWithContentsOfFile:personImagePath]];
[personView setFrame:CGRectMake(imageViewX,
                                imageViewY,
                                imageViewWidth,
                                imageViewHeight)];
[cell.contentView addSubview:personView];

UILabel *personLabel = [[UILabel alloc] initWithFrame:CGRectMake(titleLabelX,
                                                                 personView.frame.origin.y, self.view.frame.size.width - personView.frame.size.width,
                                                                 titleLabelHeight)];
personLabel.text = [dic valueForKey:@"title"];
personLabel.font = [UIFont systemFontOfSize:18.0];
[cell.contentView addSubview:personLabel];

很简单的就实现了，如果想增加其他的东西，也是很方面的，只要将自己的组建添加到cell.contentView就好了。

Could not chdir to home directory /home/USER: Permission denied

发表于 2025-06-18 分类于技术

We changed the home folder to /data/home/USER.

When I ssh to our centos server. It shows error “Could not chdir to home directory /home/USER: Permission denied”, however loggin ok. I must manually run cd ~ to go to the home directory.

Googled around, and found it is caused by selinux. The solution:

To disabling selinux or change it from enforcing to permissive.
vi /etc/sysconfig/selinux
change SELINUX from enforcing to permissive: SELINUX=permissive, then reboot.

For server could not be rebooted:
#setenforce permissive

You can check if set correctly
#getenforce

上面就是解决的办法

其实就是修改一下/etc/sysconfig/selinux

将SELINUX修改为permissive

如果不想重启机器来使配置起作用，可以直接执行

1	setenforce permissive

如果没有实现，先确定一下是否是root权限

Yii 知识点总结第一期

发表于 2025-06-18 分类于技术

使用updateCounters()来更新计数器字段。

1	Book::model()->updateCounters(['download_count' => 1], ':id=id', [':id' => $id]);

使用sendFile()来下载文件。

$type = LFilter::checkString($_GET['t']);
$dataProvider = Book::model()->findByPk($id);
$content = $this->renderPartial('book', [
    'dataProvider' => $dataProvider,
    'type' => $type,
], true, false);
Yii::app()->request->sendFile($dataProvider->name . '.' . $type, $content),

设计数据库时候如果create_time, update_time字段为int(10).在模型中使用行为插件。

public function behaviors()
{
    return [
        'CTimestampBehavior' => [
            'class' => 'zii.behaviors.CTimestampBehavior',
            'createAttribute' => 'create_time',
            'updateAttribute' => 'update_time',
        ],
    ];
}

如果有些字段使用1，2，3之类的数字存储，在程序中使用时候含义不明确。可以model中加入如下函数.

private static $_items = [];
public function loadItems($type, $code = null)
{
    self::$_items = [
        'status' => [
            '1' => Yii::t('dh', '开启'),
            '2' => Yii::t('dh', '关闭'),
        ],
        'type' => [
            '1' => Yii::t('dh', '产品'),
            '2' => Yii::t('dh', '文章'),
        ],
    ];
    return $code ? self::$_items[$type][$code] : self::$_items[$type];
}

多语言使用Yii::t()函数。

public function attributeLabels()
{
    return [
        'verifyCode' => Yii::t('default', '验证码'),
        'name' => Yii::t('default', '名字'),
        'email' => Yii::t('default', '邮箱'),
        'subject' => Yii::t('default', '标题'),
        'body' => Yii::t('default', '内容'),
        'required' => Yii::t('default', '变量"{var}"没有定义'，array('{var}' => $var));,
    ];
}

数据库表使用了前缀，则使用{{$tableName}}。

public function tableName()
{
    return '{{product}}';
}

Cookie的使用

//设置Cookie
$cookie=new CHttpCookie($name,$value);
$cookie=time()+60*60*24;
Yii::app()->request->cookies[$name]=$cookie;
//获取Cookie
$cookie=Yii::app()->request->cookies[$name];
$value=$cookie->value;
//删除Cookie
$cookie = Yii::app()->request->getCookies();
unset($cookie[$name]);

zii.widgets.jui.CJuiTabs的使用

<?php
    $this->widget('zii.widgets.jui.CJuiTabs', array(
        'tabs'=>array(
            Yii::t('book','基本信息') => $this->renderPartial('_basic',array(
                    'model' => $model,
                    'form' => $form,
            ),true),
            Yii::t('book','作品标签') => array('ajax'=> $this->createUrl('tag/boxList',array('tag'=>$model->tag))),
            Yii::t('book','作品封面') => $this->renderPartial('_image',array(
                    'model'=>$model,
                    'form'=>$form,
            ),true),
            Yii::t('book','作品公告') => $this->renderPartial('_notice',array(
                    'model'=>$model,
                    'form'=>$form,
            ),true),
        ),
        // additional javascript options for the tabs plugin
        'options'=>array(
            'collapsible'=>false,
        ),
    ));
?>

对于tabs而言，对于复杂内容的渲染结合使用renderPartial();

zii.widgets.grid.CGridView的使用

<?php
$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'chapter-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(
        'id',
        //锚点<a href="http://blog.163.com/huv520@126/blog/"></a>
        array(
            'name'=>'name',
            'type'=>'raw',
            'value'=>'CHtml::link($data->name,"/book/$data->id")',
        ),
        //图片
        array(
            'name'=>'image',
            'type'=>'image',
            'value'=>'LImages::getPath("book").$data->image',//图片相对路径
         ),
        //下拉列表
        array(
            'name'=>'type',
            'value'=>'Lookup::item("chapterType",$data->type)',
            'filter'=>Lookup::items('chapterType'),
        ),
        //内容截取
        array(
            'name'=>'content',
            'type'=>'html',
            'value'=>'mb_substr(htmlspecialchars_decode($data->content),0,100,"utf-8")',
        ),
        //时间
        array(
            'name'=>'create_time',
            'type'=>'datetime',
        ),
        // 根据相关信息读数据库
        array(
            'name'=>'user_id',
            'value'=>'User::model()->findbyPk($data->user_id)->username',
            'filter'=>false,
        ),
        array(
            'class'=>'CButtonColumn',
        ),
    ),
)); ?>

findAll()的使用;

$params = [
    'select' => 'id,name,image',
    'order' => 'total_point DESC',
    'limit' => 5,
];

Yii 控制器的action的访问限制中的 post提交限制的简单方法

发表于 2025-06-18 分类于技术

对于我跟人来说，关于在一个控制器的中做action的post限制，一般的话我是这样做的

public function actionDownload()
{
    if (Yii::app()->request->isPOSTRequest) {
        $message = [];
        if (isset($_POST['id']) && isset($_POST['url'])) {}
        if ($this->fileClick($_POST['id'], $_POST['url'])) {
            $message['code'] = 1;
        } else {
            $message['code'] = 0;
        }
        echo json_encode($message);
    }
    throw new CHttpException(400, '请求的页面不存在.');
}

感觉还不错，但是今天通过设置权限总是遇到错误，结果我发现了一个小角落的问题被我忽视了

public function filters()
{
    return [
        'accessControl', // perform access control for CRUD operations
        'postOnly + delete', // we only allow deletion via POST request
    ];
}

postOnly + delete就是这里

yii的控制还是不错的，继续感悟

Yii的AR是否带安全过滤防SQL注入 XSS攻击的说明

发表于 2025-06-18 分类于技术

关于这个说明，我引用了www.yiiframework.com 里面的qiang哥的

提到了两个问题：一是SQL Injection攻击，一个是XSS攻击。

对于前者，需要避免的是直接把用户输入嵌入到SQL里，例如：”SELECT * FROM tbl_user WHERE id={$_GET['id']}“。
恶意用户可以让$_GET['id']等于”1; DELETE FROM tbl_user“，这样就把所有的用户数据都删除了！非常危险！

解决办法有好几种。最简单的就是用param binding，请阅读PHP PDO获得相关知识。如果知道id是整数，也可以先把输入强制为整数。或者如果id是字串，可以用CDbConnection::quoteValue()把输入加上引号。如果你用的是AR，那么save()函数自动会使用param binding。如果你用findAll()之类的函数，自己生成condition部分，那就要特别小心不要直接嵌入输入。

XSS攻击主要是要避免直接显示用户的输入数据。例如echo $user->description（假设description的数据来自用户的输入）。恶意用户可以让id为一段js代码，使得其它用户查看该页面后隐式执行该代码，从而被恶意用户获得登录cookie等安全信息。

解决办法很简单，就是用CHtml::encode()。如果输入是HTML，可以用CHtmlPurifier::purify()来过滤有害代码。
