UIActivityViewController 使用大致使用步驟:

• 1 設定分享的內容,比如:

    NSString *shareTitle = @"分享的標題";
    UIImage *shareImage = [UIImage imageNamed:@"me"];
    NSURL *shareUrl = [NSURL URLWithString:@"http://www.lxweimin.com/u/acdcce712303"];
    NSArray *activityItems = @[shareTitle,
                               shareImage,
                               shareUrl]; // 必須要提供url 才會顯示分享標簽否則只顯示圖片
  

• 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

  -(NSArray *)excludetypes{
    
    NSMutableArray *excludeTypesM =  [NSMutableArray arrayWithArray:@[//UIActivityTypePostToFacebook,
                                                                      UIActivityTypePostToTwitter,
                                                                      UIActivityTypePostToWeibo,
                                                                      UIActivityTypeMessage,
                                                                      UIActivityTypeMail,
                                                                      UIActivityTypePrint,
                                                                      UIActivityTypeCopyToPasteboard,
                                                                      UIActivityTypeAssignToContact,
                                                                      UIActivityTypeSaveToCameraRoll,
                                                                      UIActivityTypeAddToReadingList,
                                                                      UIActivityTypePostToFlickr,
                                                                      UIActivityTypePostToVimeo,
                                                                      UIActivityTypePostToTencentWeibo,
                                                                      UIActivityTypeAirDrop,
                                                                      UIActivityTypeOpenInIBooks]];
    
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 11.0) {
        [excludeTypesM addObject:UIActivityTypeMarkupAsPDF];
    }
    
    return excludeTypesM;
  }
  activityVC.excludedActivityTypes = [self excludetypes];
  

• 4 設置操作回調,用戶點擊 菜單按鈕后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) {
        
        NSLog(@"activityType: %@,\n completed: %d,\n returnedItems:%@,\n activityError:%@",activityType,completed,returnedItems,activityError);
    };
  
  

• 5 顯示分享菜單

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