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")

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

cocos2dx3.x中使用物理引擎还是挺方便的

世界杯期间做个接地气的

平时创建场景

local scene = cc.Scene:create()

1	local scene = cc.Scene:create()

改成

local scene = cc.Scene:createWithPhysics()

1	local scene = cc.Scene:createWithPhysics()

这样的场景就是带物理世界的场景了

设置重力

scene:getPhysicsWorld():setGravity(cc.vertex2F(0,-1000))

1	scene:getPhysicsWorld():setGravity(cc.vertex2F(0,-1000))

声明层

local layer = cc.LayerColor:create(cc.c4f(255,255,255,255))

1	local layer = cc.LayerColor:create(cc.c4f(255,255,255,255))

声明一个函数,作用是点一下屏幕在当前位置丢下一个足球

local function onTouch(touch,event)
    local location = touch:getLocation()
    local x,y = location.x,location.y
    local football = cc.Sprite:create("football.png")
    local size = football:getContentSize()
    football:setPosition(x,y)
    football:setPhysicsBody(cc.PhysicsBody:createCircle(size.width/2))
    football:getPhysicsBody():setVelocity(cc.vertex2F(0,300))
    layer:addChild(football)
end

local function onTouch(touch,event)

local location = touch:getLocation()

local x,y = location.x,location.y

local football = cc.Sprite:create("football.png")

local size = football:getContentSize()

football:setPosition(x,y)

football:setPhysicsBody(cc.PhysicsBody:createCircle(size.width/2))

football:getPhysicsBody():setVelocity(cc.vertex2F(0,300))

layer:addChild(football)

end

声明一个触摸监听器,并和层绑定

local listener = cc.EventListenerTouchOneByOne:create()
listener:registerScriptHandler(onTouch,cc.Handler.EVENT_TOUCH_BEGAN)
layer:getEventDispatcher():addEventListenerWithSceneGraphPriority(listener,layer)

local listener = cc.EventListenerTouchOneByOne:create()

listener:registerScriptHandler(onTouch,cc.Handler.EVENT_TOUCH_BEGAN)

layer:getEventDispatcher():addEventListenerWithSceneGraphPriority(listener,layer)

创建物理世界边界

local edge = cc.Node:create()
edge:setPhysicsBody(cc.PhysicsBody:createEdgeBox(visibleSize))
edge:setPosition(visibleSize.width/2,visibleSize.height/2)
layer:addChild(edge)

local edge = cc.Node:create()

edge:setPhysicsBody(cc.PhysicsBody:createEdgeBox(visibleSize))

edge:setPosition(visibleSize.width/2,visibleSize.height/2)

layer:addChild(edge)

层添加到场景里

scene:addChild(layer)

1	scene:addChild(layer)

这样就算完成了,点一下出现一个足球还会和其他足球碰撞

首先创建一个iOS Application 选择Single View Application

ViewController.swift代码如下

import UIKit

class ViewController: UIViewController {
    
    @IBOutlet var wv:UIWebView
    
    override func viewDidLoad() {
        super.viewDidLoad()
        wv.loadRequest(NSURLRequest(URL:NSURL(string:"http://www.superyyl.com")))
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

import UIKit

class ViewController: UIViewController {

@IBOutlet var wv:UIWebView

override func viewDidLoad() {

super.viewDidLoad()

wv.loadRequest(NSURLRequest(URL:NSURL(string:"http://www.superyyl.com")))

}

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

}

在Main.storyboard里,拖入一个Web View

然后将WebView和ViewController里的wv,通过Referencing Outlets连接起来

使@IBOutlet var wv:UIWebView旁边的圆点变成实心的

接着运行,就可以看到模拟器里的WebView成功载入网页了

定义class

class Hi {
    func sayHi(){
        println("Hi superyyl")
    }
}

class Hi {

func sayHi(){

println("Hi superyyl")

}

实例化

var hi = Hi()

1	var hi = Hi()

调用类方法

hi.sayHi()//Hi superyyl

1	hi.sayHi()//Hi superyyl

继承

class Hello:Hi {   
}

1 2	class Hello:Hi { }

调用继承方法

var h = Hello()
h.sayHi()//Hi superyyl

1 2	var h = Hello() h.sayHi()//Hi superyyl

重写方法

class Hello:Hi {
    override func sayHi() {
        println("Hello superyyl")
    }
}

var h = Hello()
h.sayHi()//Hello superyyl

class Hello:Hi {

override func sayHi() {

println("Hello superyyl")

}

var h = Hello()

h.sayHi()//Hello superyyl

构造方法和成员变量

class Hello:Hi {
    var _name:String
    
    init(name:String) {
        println("Init Hello")
        self._name = name
    }
    
    override func sayHi(){
        println("Hello (self._name)")
    }
}

var h = Hello(name:"ZhangSan")
h.sayHi()//Hello ZhangSan

class Hello:Hi {

var _name:String

init(name:String) {

println("Init Hello")

self._name = name

}

override func sayHi(){

println("Hello (self._name)")

}

var h = Hello(name:"ZhangSan")

h.sayHi()//Hello ZhangSan

需要注意的是,传参数和OC一样,需要有个标签

没有返回值的调用

func sayHello(name:String) {
    println("Hello (name)")
}
sayHello("superyyl")//Hello superyyl

func sayHello(name:String) {

println("Hello (name)")

}

sayHello("superyyl")//Hello superyyl

多个返回值的调用

func getNums()->(Int,Int) {
    return (2,3)
}
let (a,b) = getNums()
println("a=(a),b=(b)")//a=2,b=3

func getNums()->(Int,Int) {

return (2,3)

}

let (a,b) = getNums()

println("a=(a),b=(b)")//a=2,b=3

函数也是类型,可以赋值

var fun = sayHello
fun("World")//Hello World

1 2	var fun = sayHello fun("World")//Hello World

输出所有偶数

for index in 0..100 {
    if index % 2 == 0 {
        println(index) //输出所有偶数
    }
}

for index in 0..100 {

if index % 2 == 0 {

println(index) //输出所有偶数

}

判断myName是否为空

var myName:String? = "superyyl"
myName = nil

if let name = myName {
    println("Hello (name)")
}

var myName:String? = "superyyl"

myName = nil

if let name = myName {

println("Hello (name)")

}
