将新浪微博 WeiboSDK 桥接集成到用Swift语言编写的iOS App

昨日女神高圆圆嫁到了台湾去,各位屌丝粉丝哭晕在厕所。别说,昨夜还真梦到了女神。于是今日发奋图强,继续进行编程工作–集成微博SDK到我的Swift程序中,用于微博授权登录。

前年曾经做过一次集成,那时还是ObjectiveC语言的天下,而今日Swift语言已成大势所趋。
由于iOS SDK是用ObjectiveC写成,在Swift中要用到语言桥接。

由于文档与代码脱节,自己摸索半天,还是遇到很多坑。特别是链接期直接抛异常出来,比如'NSInvalidArgumentException', reason: '-[__NSDictionaryM weibosdk_WBSDKJSONString]: unrecognized selector sent to instance,多是找不到链接库导致。

完整解决方案:

  • 添加ObjC语言到Swift语言的桥接头文件(Bridging-Header):新建任意ObjC文件,XCode就会提示并帮你创建这个文件。(如果要做单元测试,也要记得引用这个桥接文件)
  • 将libWeiboSDK代码全部拷入你的工程里,然后在桥接头文件中引用:

    1
    #import "libWeiBoSDK/WeiboSDK.h"
  • 在AppDelegate.swift中,更新代码如下:

    class AppDelegate: UIResponder, UIApplicationDelegate, WeiboSDKDelegate {
    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    // your other code...
    WeiboSDK.enableDebugMode(true)
    WeiboSDK.registerApp("你的移动端Appkey")
    return true
    }
    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {
    return WeiboSDK.handleOpenURL(url, delegate: self)
    }
    func application(application: UIApplication, handleOpenURL url: NSURL) -> 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.rawValue)\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.rawValue)\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()
    }
    }
  • 在发起微博授权的事件中,加入代码:

    1
    2
    3
    4
    5
    6
    7
    func callWeibo() {
    println("weibo pressed")
    var request: WBAuthorizeRequest! = WBAuthorizeRequest.request() as WBAuthorizeRequest
    request.redirectURI = "https://api.weibo.com/oauth2/default.html"
    request.scope = "all"
    WeiboSDK.sendRequest(request)
    }
  • 各种framework库都要添加到工程中,可以参考Demo工程。

    • CoreGraphics
    • Foundation
    • UIKit
    • QuartzCore
    • ImageIO
    • CoreFoundation
    • AdSupport
    • SystemConfiguration
    • Security
    • libWeiboSDK
  • 链接选项在target->build settings->linking->other linker flags中,添加-all_load
  • Info.plist中添加URL types属性,在其下继续添加URL Identifier=com.weibo, URL Schemes=wb<你的app key>
  • Swift语法不断更新中,可能会有个别语法和接口失效,没关系,安装Xcode的提示fix-it即可
  • 在微博平台上及代码中将redirectURI设置为一致的,比如”https://api.weibo.com/oauth2/default.html
  • 你的apple developer program最好没过期

编译环境

XCode 6.1
WeiboSDK 2.4.2
