齊桓公之ios app微信登入授權及分享對接
阿新 • • 發佈：2022-06-01
微信sdk的引入及相關匯入你可以參考這裡：齊桓公(小白)首次盲接iosapp及微信sdk及發包
這裡我們僅討論並完成wxsdk的登入授權和分享編碼
首先建立類檔案WechatManager.mm,和標頭檔案WechatManager.h
怎麼建立？ 點選file ---- new file ---- 選擇objective-cfile ----- 一步步下去
微信的授權等相關操作可分為以下幾步
1、向微信註冊，片段程式碼如下
說明：
- 註釋的startLogByLevel.... 及後面checkUniversalLinkReady......是微信提供的程式碼除錯工具方法，啟動可以從日誌裡檢視問題出在什麼地方
- wxid是微信公眾平臺的appid，universalLink:@這裡的url是registerUniversalUrl，https://域名/path 當然如果沒有path則直接域名url即可
2、檢查微信安裝狀態
+(int)doIsWXAppInstalled { BOOL isInstalled = [WXApi isWXAppInstalled]; BOOL isSepport = [WXApi isWXAppSupportApi]; if (isInstalled == YES && isSepport == YES) { return 1; } else { return 0; } }
3、登入授權
說明：這裡由於是js回撥過來的登入，所以用了JSBridge，
wxLoginCallBack方法是jsbridge回撥給js的方法，jsbridge會在ios對接內購支付的時候詳解
這裡要重寫wxapi.h 裡的這個回撥方法，登入結果返回會回撥到這裡
- (void)onResp:(BaseResp*)resp;
+ (void)weChatLogin { if(![WeChatManger doIsWXAppInstalled]) { [JSBridge wxLoginCallBack:-3 code:@"" tip:@"登陸失敗！您未安裝微信!"]; } else { SendAuthReq* req = [[SendAuthReq alloc] init]; req.scope = @"snsapi_message,snsapi_userinfo,snsapi_friend,snsapi_contact"; // @"post_timeline,sns" req.state = @"none"; [WXApi sendReq:req completion:nil]; } }
接下來是返回，這裡的返回相容處理了分享
- (void) onResp:(BaseResp*)resp { if([resp isKindOfClass:[SendAuthResp class]]) { SendAuthResp *temp = (SendAuthResp*)resp; if (temp.errCode== 0 && temp.code && temp.code.length != 0) { [JSBridge wxLoginCallBack:1 code:temp.code tip:@"登入成功"]; } else{ [JSBridge wxLoginCallBack:0 code:@"" tip:@"登入失敗!"]; } } else if([resp isKindOfClass:[SendMessageToWXResp class]]) { switch (resp.errCode) { case WXSuccess: [JSBridge wxShareCallBack:1 tip:@"分享成功!"]; break; case WXErrCodeAuthDeny: [JSBridge wxShareCallBack:-1 tip:@"分享已取消!"]; break; default: [JSBridge wxShareCallBack:0 tip:@"分享失敗!"]; break; } } }
3、分享
注意分享的幾個引數 shareTitle 、shareType、shareDesc、shareImage等
+ (void)weChatShare:(NSString*) jsonParam { NSData* data = [jsonParam dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]; if (json == nil) return; NSString *shareType = json[@"shareType"]; if(![WeChatManger doIsWXAppInstalled]) { [JSBridge wxShareCallBack:-3 tip:@"未安裝微信!"]; } NSString *shareTitle = json[@"shareTitle"];NSString *shareIcon = json[@"shareIcon"]; NSString *shareDesc = json[@"shareDesc"];NSString *shareLink = json[@"shareLink"]; NSString *shareImageData = json[@"shareImage"]; if( shareTitle == nil || shareTitle.length < 1 || shareIcon == nil || shareIcon.length < 1 || shareDesc == nil || shareDesc.length < 1 || shareLink == nil || shareLink.length < 1 ) { [JSBridge wxShareCallBack:-5 tip:@"分享資訊缺失!"]; } else { int nRet = 0; if( [shareType isEqualToString:@"text"] )nRet = 1; else if ( [shareType isEqualToString:@"webView"] )nRet = 2; else if ( [shareType isEqualToString:@"img"] )nRet = 3; switch (nRet) { case 1: { //初始化一個WXWebpageObject物件，填寫url WXWebpageObject *webpageObject = [WXWebpageObject object]; webpageObject.webpageUrl = shareLink; //用WXWebpageObject物件初始化一個WXMediaMessage物件，填寫標題，描述 WXMediaMessage *message = [WXMediaMessage message]; message.title = shareTitle; message.description = shareDesc; NSDictionary *infoPlist = [[NSBundle mainBundle] infoDictionary]; NSString *icon = [[infoPlist valueForKeyPath:@"CFBundleIcons.CFBundlePrimaryIcon.CFBundleIconFiles"] lastObject]; UIImage * shareImage = [UIImage imageNamed:icon]; [message setThumbImage:shareImage]; message.mediaObject = webpageObject; SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init]; req.bText = NO; req.message = message; req.scene = WXSceneSession; [WXApi sendReq:req completion:nil]; break; } case 2: { break; } case 3: { //UIImage *image = [[ViewController GetIOSViewController] getScreenShot]; NSArray *array = [shareImageData componentsSeparatedByString:@","]; NSData *ImageData = [[NSData alloc] initWithBase64EncodedString:array[1] options:NSDataBase64DecodingIgnoreUnknownCharacters]; UIImage *image = [UIImage imageWithData:ImageData]; // 下面就是組裝要分享到微信的內容 WXMediaMessage *message=[WXMediaMessage message]; [message setThumbImage:image]; WXImageObject *imageObject=[WXImageObject object]; imageObject.imageData=UIImagePNGRepresentation(image); message.mediaObject=imageObject; SendMessageToWXReq *req=[[SendMessageToWXReq alloc]init]; req.bText=NO; req.message=message; req.scene=WXSceneSession; [WXApi sendReq:req completion:nil]; break; } default:{ [JSBridge wxShareCallBack:-6 tip:@"不支援的分享型別！"]; break; } } } }
至此，微信的ios客戶端對接完成，接下來就是掉登入分享的H5這邊，H5這邊通過jsbridge直接掉wxlogin方法，在回撥方法裡處理相關的邏輯，這裡和web對接微信沒啥區別，不過一個是引入js檔案，一個是掉ios oc方法而已，程式碼片段如下
static doLogin() { Native.callWithBack(function (msg) { log("doLogin WXdoAuth code is :", msg["code"]); LoginHelperWXNative.onGetCode(msg["code"]); this.tag = 0; }, "wxLogin",''); this.tag = 1; }
下面是完整的WechatManager.mm和標頭檔案WechatManager.h 內容

微信sdk的ios對接一版情況下從github上可以搬過來用，都是對接相關的部分，如果H5對接過或者公眾號小程式對接過，對流程很熟悉的話，基本就沒什麼問題了。
天將降大任於斯人也，必先苦其心志，勞其筋骨，餓其體膚....對齊桓公來說確實如此，微信sdk對接遇到的問題總結如下：
1、sdk庫的匯入相當棘手，建議參照官網一步一步來
2、登入授權的universal url配置一定要在訪問【域名+apple-app-site-association】一定要能下載這個檔案，否則配置失敗，微信授權會報----universal Link校驗不通過 的錯誤
3、分享的時候分享連線一定要提供正確，這裡會報一些分享的錯誤，沒有關係有報錯就好解決
最後說一句：磚石之所以能成磚石是因為他經過了千百萬年的磨練 一切事物皆如此 倘不經歷練 何以知其真 ？何以享其樂？以此而已！
