iOS隐藏键盘

薛定谔的nil2016年5月10日 0 Comments

1、服从协议

UITextViewDelegate, UITextFieldDelegate

1	UITextViewDelegate, UITextFieldDelegate

2、设置代理

3、添加隐藏按钮

void (^addTopView)(UIView *) = ^(UIView *view) {
    UIToolbar *topView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 35)];
    UIBarButtonItem *flexBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *dismissKeyBoardButton;
    dismissKeyBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyBoard)];
    topView.backgroundColor = [UIColor whiteColor];
    NSArray *buttonsArray = @[flexBtn, dismissKeyBoardButton];
    if (view.class == [UITextField class]) {
        ((UITextField *)view).inputAccessoryView = topView;
        topView.items = buttonsArray;
    }
    if (view.class == [UITextView class]) {
        ((UITextView *)view).inputAccessoryView = topView;
        topView.items = buttonsArray;
    }
};
addTopView(self.textField);
addTopView(self.textView);

UIToolbar *topView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 35)];

UIBarButtonItem *flexBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

UIBarButtonItem *dismissKeyBoardButton;

dismissKeyBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyBoard)];

topView.backgroundColor = [UIColor whiteColor];

NSArray *buttonsArray = @[flexBtn, dismissKeyBoardButton];

if (view.class == [UITextField class]) {

((UITextField *)view).inputAccessoryView = topView;

topView.items = buttonsArray;

}

if (view.class == [UITextView class]) {

((UITextView *)view).inputAccessoryView = topView;

topView.items = buttonsArray;

}

};

addTopView(self.textField);

addTopView(self.textView);

4、添加空白处点击隐藏

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard)];
tapGestureRecognizer.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGestureRecognizer];

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard)];

tapGestureRecognizer.cancelsTouchesInView = NO;

[self.view addGestureRecognizer:tapGestureRecognizer];

5、添加键盘隐藏方法

- (void)dismissKeyBoard {
    [self.textField resignFirstResponder];
    [self.textView resignFirstResponder];
}

- (void)dismissKeyBoard {

[self.textField resignFirstResponder];

[self.textView resignFirstResponder];

服务器切换测试

薛定谔的nil2016年3月1日 0 Comments

在美国的VPS又被墙了！

之前已经被墙折腾的换了好几次服务器，这次尤其严重，不但国内访问不了服务器，连服务器都没法访问国内了！这导致我两个爬虫都无法正常抓数据，我不得不做出妥协，把整个服务器迁移到国内，并老老实实备案。

迁移完了写篇文章测试一下博客是否还正常。

DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

Uninstalling six-1.4.1:

去网上查找解决方法，看到了这个：“OSError: [Errno 1] Operation not permitted” when installing Scrapy in OSX 10.11 (El Capitan) (System Integrity Protection)，发现问题一模一样，于是就按照回答开始尝试。

按照最高票回答的方法尝试手动更新six：

然而并没有成功更新！于是去看了：Source: github.com/pypa/pip/issues/3165

按照里面的某些讨论进行尝试：

MacBook-Pro:~ EverybodyLies$ sudo -H pip install Scrapy --upgrade --ignore-installed six

1	MacBook-Pro:~ EverybodyLies$ sudo -H pip install Scrapy --upgrade --ignore-installed six

的确没有再次报错，但是我觉得并没有解决这个问题（后来检查日志应该是更新成功了）。

另一个同学在尝试中使用easy_install升级six，解决了这个问题，我也进行了这种尝试：

非常顺利就能完成six的升级。

一些思考：

在解决这个问题的过程中我一开始觉得是10.11中SIP的问题，而且很多文章也说是SIP的问题。

但是后来另一个同学用easy_install很容易的就升级了six，我突然意识到可能是six这个包本来是用easy_install安装的，因此pip才无法卸载six。

Xcode资源文件清理：删除无用的旧设备支持文件

薛定谔的nil2016年1月24日 0 Comments

Mac硬盘只剩下20G可用空间了，做了清理也只清理出了3G可用空间，但是印象里自己并没有在电脑存太多东西啊！于是开始做手动磁盘清理，在检查用户目录下的资源库时，发现这个目录异常的大：

~/Library/Developer/Xcode/iOS\ DeviceSupport

里面似乎是各个版本的iOS支持文件，甚至还有6.1.3版本的支持文件。如果能删除旧版的支持文件，那就能给电脑腾出一大块空间啊！于是找了一下资料，看能不能删除。

根据这个回答，删除旧版支持文件是完全没有问题的，甚至可以全部删除，并且应该定期删除！

phpMyAdmin数据库乱码问题

薛定谔的nil2016年1月21日 0 Comments

第一次写后端，遇到了不少问题，这个问题比较坑！

问题描述：

1，从网页提交数据库数据，在phpmyadmin上显示乱码，在网页输出是好的。

2，用phpmyadmin从数据库插入数据，输出到网页后是乱码。

环境看似没有任何问题：网页已经声明使用『UTF-8』，数据库已经设置编码为『utf8_general_ci』。

为何还是出现了编码问题呢？

答：从网页提交数据库数据，在phpmyadmin上显示乱码，在网页输出是好的，说明提交的数据和数据库的编码不一样，提取数据的编码和提交数据的编码一样。A->B->A型

解决方案：

把所以关于数据库查询、插入的语句前全部加上一行：

mysql_query("SET NAMES 'utf8'");

1	mysql_query("SET NAMES 'utf8'");

Ubuntu Server使用命令行版VPN客户端

薛定谔的nil2016年1月17日 0 Comments

为了能在外网玩上内网的MC服，朱总和我在腾讯云的学生优惠服务器上部署了一个VPN，想通过让内网MC服务器和客户端同时登录一个外网VPN的方式，曲线实现MC服务器和客户端处在同一局域网。

这样就涉及到让ubuntu server连接VPN的问题。

需要连接VPN的服务器是一台Ubuntu 14.04.3 LTS，使用pptp-linux软件连接VPN。

首先是安装软件包

sudo apt-get update
sudo apt-get install pptp-linux
pptpsetup --help

sudo apt-get update

sudo apt-get install pptp-linux

pptpsetup --help

确认已经安装好后，根据帮助使用pptpsetup建立VPN连接。

pptpsetup --create --server [--domain ]
--username [--password ]
[--encrypt] [--start]

pptpsetup --delete

Options:

* the name you wish to use to refer to the tunnel (you choose it),
* the IP address or host name of the server,
* the authentication domain name (optional),
* the username you are to use,
* the password you are to use,
* whether encryption is required,
* whether to start the connection after configuration.

Linux下批量替换文件名中的部分字段

薛定谔的nil2016年1月16日 0 Comments

从网上下载了一批旧的影视剧资源，命名倒是挺规范，但是不和我的胃口，想要重新命名。

但是不能用简单的批量重命名，因为原文件名里包含一个集名的字段，这个字段一定是不同的。如果用批量重命名，会导致这个字段消失，然而我想保留它，于是想批量替换掉我不想要的字段。

Mac上用brew安装了rename，默认安装的是Perl 语言版本。

命令格式：rename ‘s/原字符串/新字符串/’ 文件名

字符串支持正则，要注意字符元的使用和转义。

同时，原字符串只会在一个文件名中匹配一次，例如：

[舌尖上的中国][01][高清版][HR-HDTV].mp4

执行：rename ‘s/\]\[/./’

[舌尖上的中国.01][高清版][HR-HDTV].mp4

换端口号，并禁止root登陆

netstat –apn | grep [myport]

1	netstat –apn \| grep [myport]

测试不会冲突后修改

sudo nano /etc/ssh/sshd_config

1	sudo nano /etc/ssh/sshd_config

找到

Port 22

修改为自己想要的端口，找到

PermitRootLogin yes

改为 no 。

tree命令在Mac终端中文文件名显示异常

薛定谔的nil2015年10月20日 0 Comments

想要给一个朋友发自己硬盘里电子书资源列表，于是想到了tree命令。

安装后一试，

居然是这个样子！！！

最先想到的是编码错误，于是百度『linux tree 乱码』，尝试若干种解决方法，并没有什么卵用！

无意中发现了这篇文章http://wwdd23.github.io/2015/01/09/mac-tree-chinese-display-error.html，终于解决了问题。

WordPress无法发送邮件问题的解决过程

薛定谔的nil2015年10月2日 0 Comments

前两天忘记了wordpress的后台密码，找回的过程中给出如下提示：

无法发送电子邮件。

可能原因：您的主机禁用了mail()函数。

后来发现注册的时候密码邮件发送也是不成功的，就寻思找个时间解决这个问题。

国庆假期刚好抽空研究，结果让我很惊讶，于是记录下来。

首先是wp提示禁用了mail()函数，但是之前在配置wecenter的时候已经把邮件发送调通了，一切正常。

但是毕竟提示了，那就测试一下吧。网上搜索，用个探针进行测试。

<?php
if (function_exists('mail')) echo "^_^ mail()函数可以使用！";
else echo "- -! mail()函数不可以使用！";
?>

1

2

3

4

<?php

if (function_exists('mail')) echo "^_^ mail()函数可以使用！";

else echo "- -! mail()函数不可以使用！";

?>

测试完全没有问题。然后又研究半天还是没找到头绪，决定彻底测试一下，确认不是mail()函数的问题，于是用了第二个探针。

<?php
$text = "This is a test!";
// 将邮箱地址改成你的
$mail = 'xxx@163.com';
// 发送邮件
mail($mail, "Mail Test", $text);
echo "Message has been sent !";
?>

<?php

$text = "This is a test!";

// 将邮箱地址改成你的

$mail = 'xxx@163.com';

// 发送邮件

mail($mail, "Mail Test", $text);

echo "Message has been sent !";

?>

这次发现个问题，网页显示发送完成，但是邮箱却收不到，看来是mail()函数运行中出了问题。

于是去找日志，结果发现根本没有日志，既找不到日志文件，又无法在系统日志中找到。不会是没装邮件程序吧，不应该啊，毕竟wecenter邮件好好的啊！还是检查下比较好。

ps aux | grep sendmail

1	ps aux \| grep sendmail

返回

root 7458 0.0 0.1 13420 940 pts/0 S+ 07:32 0:00 grep --color=auto sendmail

1	root 7458 0.0 0.1 13420 940 pts/0 S+ 07:32 0:00 grep --color=auto sendmail

果然是没装！！！

So，直接安装好了。

在R6300v2的Tomato固件中使用nano和screen时出现不支持xterm-256color的情况，错误提示如下：

nano error: Error opening terminal: xterm-256color

screen error: Cannot find termcap entry for ‘xterm-256color’.

解决方案：

Quick fix: run TERM=xterm screen instead of screen.
