文件“选择其它应用打开”及文件共享功能

 

一：选择其它应用打开

如图：可以将QQ或微信的zip文件拷贝到第三方App的沙盒中，Document文件夹下，方便用户操作使用

 

 

1：具体操作将下面Code添加到info.plish文件里面

<key>CFBundleDocumentTypes</key>

    <array>

        <dict>

            <key>CFBundleTypeIconFiles</key>

            <array>

                <string>icon-hex</string>

                <string>icon-hex@2x</string>

            </array>

            <key>CFBundleTypeName</key>

            <string>Distribution Packet (ZIP)</string>

            <key>CFBundleTypeRole</key>

            <string>Viewer</string>

            <key>LSHandlerRank</key>

            <string>Default</string>

            <key>LSItemContentTypes</key>

            <array>

                <string>com.pkware.zip-archive</string>

            </array>

        </dict>

        <dict>

        <key>CFBundleTypeIconFiles</key>

       <array>

       <string>icon_22x29</string>

       <string>icon_44x58</string>

       <string>icon_64x64</string>

       <string>icon_320x320</string>

       </array>

       <key>CFBundleTypeName</key>

       <string>allFiles</string>

       <key>LSHandlerRank</key>

       <string>Owner</string>

       <key>LSItemContentTypes</key>

       <array>

       <string>public.data</string>

       </array>

       </dict>

    </array>

二：文件分享

      PS：将本地文件分享到QQ或微信中，一般文件格式需要压缩包

      

  //分享文件
 NSURL *url = [NSURL fileURLWithPath:myFilePath];//需要打开的文件url

        

        //在这里呢 如果想分享图片 就把图片添加进去  文字什么的通上

        NSArray *activityItems = @[url];

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

        //不出现在活动项目

        activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll,UIActivityTypeMail];

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

        // 分享之后的回调

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

    {

            if (completed){

                //分享 成功

                NSLog(@"completed");

            }else{

                //分享 取消

                NSLog(@"cancled");

            }

        };
