As we all know. 苹果在iOS7.1中的Adhoc强制使用https链接,这下公司的小伙伴就不能愉快的通过内网下载安装测试包了

经过一番折腾,终于实现了自签署SSL证书让手机通过浏览器在线安装ipa

1. 环境

开发环境:Mac OS X 10.9.4+Xcode6Beta5

服务器:CentOS 6.5 x64+apache2

2. 客户端准备部署文件

a)先去developer.apple.com申请证书和描述文件(adhoc,过程略去不表)
b)将工程打包成ipa,如Demo.ipa,准备一个Icon.png和一个Icon@2x.png
c)建立Demo.plist文件

<?xml version="1.0" encoding="UTF-8"?>

d)上传Demo.ipa,Demo.plist,Icon.png,Icon@2x.png到/var/www/html/ipa目录下备用

3.服务端配置

a)安装openssl

#安装openssl
yum -y install mod_ssl
#确认安装成功
rpm -qa | grep openssl

#安装openssl

yum -y install mod_ssl

#确认安装成功

rpm -qa | grep openssl

b)生成证书

#建立文件夹
mkdir /etc/httpd/ssl
cd /etc/https/ssl
#用openssl选择rsa非对称算法和des3对称加密算法来制作CA证书
openssl genrsa -des3 -out my-ca.key 2048
#然后使用x509标准签署证书
openssl req -new -x509 -days 3650 -key my-ca.key -out my-ca.crt
#现在有了CA证书了，就可以用它来为我们的网站颁发ssl证书了。同制作CA证书一样，我们需要先为服务器生成密钥对
openssl genrsa -des3 -out mars-server.key 2048
#生成了密钥mars-server.key后，根据它生成csr证书文件
#这里面要注意了Common Name的值要和你的域名一致，否则后面客户端浏览器验证域名不正确会不通过的。
openssl req -new -key mars-server.key -out mars-server.csr
#下面就用CA证书来签署服务器证书了
openssl x509 -req -in mars-server.csr -out mars-server.crt -sha1 -CA my-ca.crt -CAkey my-ca.key -CAcreateserial -days 3650
#开机自动启动apache时免密码
openssl rsa -in mars-server.key -out mars-server.key.insecure

#建立文件夹

mkdir /etc/httpd/ssl

cd /etc/https/ssl

#用openssl选择rsa非对称算法和des3对称加密算法来制作CA证书

openssl genrsa -des3 -out my-ca.key 2048

#然后使用x509标准签署证书

openssl req -new -x509 -days 3650 -key my-ca.key -out my-ca.crt

#现在有了CA证书了，就可以用它来为我们的网站颁发ssl证书了。同制作CA证书一样，我们需要先为服务器生成密钥对

openssl genrsa -des3 -out mars-server.key 2048

#生成了密钥mars-server.key后，根据它生成csr证书文件

#这里面要注意了Common Name的值要和你的域名一致，否则后面客户端浏览器验证域名不正确会不通过的。

openssl req -new -key mars-server.key -out mars-server.csr

#下面就用CA证书来签署服务器证书了

openssl x509 -req -in mars-server.csr -out mars-server.crt -sha1 -CA my-ca.crt -CAkey my-ca.key -CAcreateserial -days 3650

#开机自动启动apache时免密码

openssl rsa -in mars-server.key -out mars-server.key.insecure

c)配置apache

vi /etc/httpd/conf.d/ssl.conf
#更改以下信息
SSLEngine on
SSLCertificateFile /etc/httpd/ssl/mars-server.crt
SSLCertificateKeyFile /etc/httpd/ssl/mars-server.key.insecure
SSLCACertificateFile /etc/httpd/ssl/my-ca.crt
#重启
service httpd restart

vi /etc/httpd/conf.d/ssl.conf

#更改以下信息

SSLEngine on

SSLCertificateFile /etc/httpd/ssl/mars-server.crt

SSLCertificateKeyFile /etc/httpd/ssl/mars-server.key.insecure

SSLCACertificateFile /etc/httpd/ssl/my-ca.crt

#重启

service httpd restart

d)将生成的my-ca.crt拷贝到/var/www/html/ipa目录下备用

4. Let’s Go!

a)在iOS设备上打开safari访问,https://www.your-domain.com/ipa/my-ca.crt,信任并安装
b)在iOS设备上打开safari访问,itms-services://?action=download-manifest&url=https://www.your-domain.com/ipa/Demo.plist

5. 还有什么?

a)安装设备的udid需要在描述文件里
b)做一个网页,引导用户先安装crt,再点击itms-service

这个需求来自于工作中的一个需求

两个城池之间的路径是美术事先画好的,武将需要沿着画好的曲线行进

经过查找资料,发现了这篇文章

用到了下面这个公式：
阶贝塞尔曲线可如下推断。给定点P0、P1、…、Pn，其贝塞尔曲线即
$贝塞尔曲线公式$ 高阶曲线为建构高阶曲线，便需要相应更多的中介点。对于三次曲线，可由线性贝塞尔曲线描述的中介点Q0、Q1、Q2，和由二次曲线描述的点R0、R1所建构：
三次贝塞尔曲线

对于四次曲线，可由线性贝塞尔曲线描述的中介点Q0、Q1、Q2、Q3，由二次贝塞尔曲线描述的点R0、R1、R2，和由三次贝塞尔曲线描述的点S0、S1所建构：
四次贝塞尔曲线

更复杂的:
五次贝塞尔曲线

最后放一张效果图

这个问题一开始困扰了我一段时间

原因是Swift继承@protocol的时候颜色会和Swift里NSObjectProtocol的颜色不一样

我以为不能继承了

首先在Bridge-Header.h里(没有的话,创建一个Objective-C的类,会提示创建,再删除OC的类就可以了)

#import "WeiboSDK.h"

1	#import "WeiboSDK.h"

然后在Swift里就能正确出现代码提示了

继承protocol这么写

class AppDelegate: UIResponder, UIApplicationDelegate,WeiboSDKDelegate

1	class AppDelegate: UIResponder, UIApplicationDelegate,WeiboSDKDelegate

注意一点,要把实现也写上,否则Swift编译是不通过的

根据OC版本的SDK,翻译成Swift

    func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
        // Override point for customization after application launch.
        WeiboSDK.enableDebugMode(true);
        WeiboSDK.registerApp(APPID);
        return true
    }
    
    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
        return WeiboSDK.handleOpenURL(url, delegate: self)
    }
    
    func didReceiveWeiboRequest(request: WBBaseRequest!) {
        if (request.isKindOfClass(WBProvideMessageForWeiboRequest)) {
            //TODO: sth
        }
    }

    func didReceiveWeiboResponse(response: WBBaseResponse!) {
        if (response.isKindOfClass(WBSendMessageToWeiboResponse)) {
            var message = "响应状态:(response.statusCode.toRaw())n响应UserInfo数据:(response.userInfo)n原请求UserInfo数据:(response.requestUserInfo)"
            var alert = UIAlertView(title: "发送结果", message: message, delegate: nil, cancelButtonTitle: "确定")
            alert.show()
        } else if (response.isKindOfClass(WBAuthorizeResponse)) {
            var message = "响应状态: (response.statusCode.toRaw())nresponse.userId: ((response as WBAuthorizeResponse).userID)nresponse.accessToken: ((response as WBAuthorizeResponse).accessToken)n响应UserInfo数据: (response.userInfo)n原请求UserInfo数据: (response.requestUserInfo)"
            var alert = UIAlertView(title: "认证结果", message: message, delegate: nil, cancelButtonTitle: "确定")
            alert.show()
        }
    }

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {

// Override point for customization after application launch.

WeiboSDK.enableDebugMode(true);

WeiboSDK.registerApp(APPID);

return true

}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {

return WeiboSDK.handleOpenURL(url, delegate: self)

}

func didReceiveWeiboRequest(request: WBBaseRequest!) {

if (request.isKindOfClass(WBProvideMessageForWeiboRequest)) {

//TODO: sth

}

func didReceiveWeiboResponse(response: WBBaseResponse!) {

if (response.isKindOfClass(WBSendMessageToWeiboResponse)) {

var message = "响应状态:(response.statusCode.toRaw())n响应UserInfo数据:(response.userInfo)n原请求UserInfo数据:(response.requestUserInfo)"

var alert = UIAlertView(title: "发送结果", message: message, delegate: nil, cancelButtonTitle: "确定")

alert.show()

} else if (response.isKindOfClass(WBAuthorizeResponse)) {

var message = "响应状态: (response.statusCode.toRaw())nresponse.userId: ((response as WBAuthorizeResponse).userID)nresponse.accessToken: ((response as WBAuthorizeResponse).accessToken)n响应UserInfo数据: (response.userInfo)n原请求UserInfo数据: (response.requestUserInfo)"

var alert = UIAlertView(title: "认证结果", message: message, delegate: nil, cancelButtonTitle: "确定")

alert.show()

}

最后在合适的地方调用

    // MARK: - 微博登录按钮
    @IBAction func onWeiboLoginClick(sender: AnyObject) {
        var request: WBAuthorizeRequest! = WBAuthorizeRequest.request() as WBAuthorizeRequest
        request.redirectURI = "https://api.weibo.com/oauth2/default.html"
        request.scope = "all"
        
        WeiboSDK.sendRequest(request)
    }

// MARK: - 微博登录按钮

@IBAction func onWeiboLoginClick(sender: AnyObject) {

var request: WBAuthorizeRequest! = WBAuthorizeRequest.request() as WBAuthorizeRequest

request.redirectURI = "https://api.weibo.com/oauth2/default.html"

request.scope = "all"

WeiboSDK.sendRequest(request)

}

微博SDK集成登录功能就做好了

直接上代码

let task = NSTask()
task.launchPath = "/bin/echo"
task.arguments = ["first-argument", "second-argument"]

let pipe = NSPipe()
task.standardOutput = pipe
task.launch()

let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output: String = NSString(data: data, encoding: NSUTF8StringEncoding)

print(output)

let task = NSTask()

task.launchPath = "/bin/echo"

task.arguments = ["first-argument", "second-argument"]

let pipe = NSPipe()

task.standardOutput = pipe

task.launch()

let data = pipe.fileHandleForReading.readDataToEndOfFile()

let output: String = NSString(data: data, encoding: NSUTF8StringEncoding)

print(output)

在swift里可以轻松调用objective-c的类

已经在目录下新建了一个setting.plist

let settingPath = NSBundle.mainBundle().pathForResource("setting", ofType: "plist")
let settingDict = NSDictionary(contentsOfFile: settingPath)
let namesStr = settingDict.objectForKey("lang_names")

let settingPath = NSBundle.mainBundle().pathForResource("setting", ofType: "plist")

let settingDict = NSDictionary(contentsOfFile: settingPath)

let namesStr = settingDict.objectForKey("lang_names")

svn使用广泛,但是每个目录下都放一个.svn文件夹着实让我们复制起来很蛋疼

下面这条命令可以清除所有.svn文件夹

sudo find /path/to/delete/ -name ".svn" -exec rm -rf {} ;

1	sudo find /path/to/delete/ -name ".svn" -exec rm -rf {} ;

一般情况下,我们使用sprite->getBoundingBox()->containsPoint(touchLocation)来判断是否触摸到了一个精灵.

需求是万变的,经常需求要求我们触摸时判断一个不规则图形

CCRenderTexture* render = CCRenderTexture::create(CCDirector::sharedDirector()->getWinSize().width, CCDirector::sharedDirector()->getWinSize().height);
render->begin();
sprite->visit();
GLubyte pColor[4];
glReadPixels(location.x,location.y,1,1,GL_RGBA,GL_UNSIGNED_BYTE,&pColor[0]);
if (pColor[3] != 0) {
    render->end();
    return false;
}
render->end();
return true;

CCRenderTexture* render = CCRenderTexture::create(CCDirector::sharedDirector()->getWinSize().width, CCDirector::sharedDirector()->getWinSize().height);

render->begin();

sprite->visit();

GLubyte pColor[4];

glReadPixels(location.x,location.y,1,1,GL_RGBA,GL_UNSIGNED_BYTE,&pColor[0]);

if (pColor[3] != 0) {

render->end();

return false;

}

render->end();

return true;

mac自带的终端配色实在是不咋地

于是网上参考加上自己习惯,以下是设置效果

首先在”终端”->”偏好设置” 设置”Homebrew”为默认

设置字体为Menlo Blod 14pt

cd ~
touch .bash_profile
vi .bash_profile

cd ~

touch .bash_profile

vi .bash_profile

然后输入

# for color
export CLICOLOR=1
# h:W u$
export PS1='[�33[01;33m]u@W$[�33[00m] '

# for color

export CLICOLOR=1

# h:W u$

export PS1='[33[01;33m]u@W$[33[00m] '

然后使配置生效

source .bash_profile

1	source .bash_profile
