ios 自帶UIActivityViewController分享

UIActivityViewController 使用大致使用步驟:

• //原生分享

  -(void)share{

      //1.設定分享的內容,比如:

      NSString *shareTitle = @"隱祕的角落";

      UIImage *shareImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1593694996876&di=cb27080027a6748f99ca4ac4a49fee29&imgtype=0&src=http%3A%2F%2Fimagepphcloud.thepaper.cn%2Fpph%2Fimage%2F74%2F157%2F824.jpg"]]];

      NSURL *shareUrl = [NSURL URLWithString:@"https://www.iqiyi.com/v_2ffkws0bgr0.html?vfm=2008_aldbd&fv=p_02_01"];

      NSArray *activityItems = @[shareTitle,

                                 shareImage,

                                 shareUrl]; // 必須要提供url 纔會顯示分享標籤否則只顯示圖片

      //2.創建分享的控制器

      UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];

      

      //3.設定不想顯示的平臺和功能

      activityVC.excludedActivityTypes = [self excludetypes];

      

      //4. 設置操作回調,用戶點擊 菜單按鈕後事件執行完成會回調這個block

      activityVC.completionWithItemsHandler = ^(UIActivityType  _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {

          if (completed) {

              NSLog(@"分享成功");

          }else{

              NSLog(@"分享失敗");

          }

   

      };

      

      //5.顯示分享菜單

      [self presentViewController:activityVC animated:YES completion:nil];

  }

   

  -(NSArray *)excludetypes{

      NSMutableArray *excludeTypeM = [NSMutableArray arrayWithArray:@[//UIActivityTypePostToFacebook,

      UIActivityTypePostToTwitter,

      UIActivityTypePostToWeibo,

      UIActivityTypeMessage,

      UIActivityTypeMail,

      UIActivityTypePrint,

      UIActivityTypeCopyToPasteboard,

      UIActivityTypeAssignToContact,

      UIActivityTypeSaveToCameraRoll,

      UIActivityTypeAddToReadingList,

      UIActivityTypePostToFlickr,

      UIActivityTypePostToVimeo,

      UIActivityTypePostToTencentWeibo,

      UIActivityTypeAirDrop,

      UIActivityTypeOpenInIBooks]];

      if (@available(iOS 11.0, *)) {

          [excludeTypeM addObject:UIActivityTypeMarkupAsPDF];

      } else {

          // Fallback on earlier versions

      }

      return excludeTypeM;

  }

下面我們再來看一個第三方的分享：WYShareSDK

如果是用cocoapods管理工具管理項目的話，只需要在Podfile裏添加一句 pod 'WYShareSDK' 就可以了。

根據上面我們所說的，原生的分享不需要第三方平臺的appKey和URL Schemes，那麼第三方的分享就需要了，好了，下面我們就來做一些項目的準備工作：

【1】在Xcode中,選擇你的工程設置項,選中TARGETS一欄,在info標籤欄的URL type添加URL scheme 爲你在各大平臺所註冊應用程序的id (如下圖所示)

【2】針對iOS9的適配.右擊項目中的info.plist,然後用Open as -> Source Code的方式打開,增加如下代碼:
 

<key>LSApplicationQueriesSchemes</key>
 <array>
  <string>wechat</string>
  <string>weixin</string>
  <string>sinaweibohd</string>
  <string>sinaweibo</string>
  <string>sinaweibosso</string>
  <string>weibosdk</string>
  <string>weibosdk2.5</string>
  <string>mqqapi</string>
  <string>mqq</string>
  <string>mqqOpensdkSSoLogin</string>
  <string>mqqconnect</string>
  <string>mqqopensdkdataline</string>
  <string>mqqopensdkgrouptribeshare</string>
  <string>mqqopensdkfriend</string>
  <string>mqqopensdkapi</string>
  <string>mqqopensdkapiV2</string>
  <string>mqqopensdkapiV3</string>
  <string>mqzoneopensdk</string>
  <string>wtloginmqq</string>
  <string>wtloginmqq2</string>
  <string>mqqwpa</string>
  <string>mqzone</string>
  <string>mqzonev2</string>
  <string>mqzoneshare</string>
  <string>wtloginqzone</string>
  <string>mqzonewx</string>
  <string>mqzoneopensdkapiV2</string>
  <string>mqzoneopensdkapi19</string>
  <string>mqzoneopensdkapi</string>
  <string>mqzoneopensdk</string>
 </array>
<!--  讓iOS9 退回到以前可以支持http請求  -->
 <key>NSAppTransportSecurity</key>
 <dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
 </dict>

【3】選中項目設置,在Build Settings中的Other Linker Flags中增加-fobj-arc和-ObjC

這時編譯一下你的項目,如果沒有報錯,恭喜你環境搭建成功

接下來.分享的代碼使用 在AppDelegate中註冊 微信/QQ/和微博

在你需要分享的地方直接導入WYShareSDK.h,調用其對應的方法分享到各個平臺.例:
