引言

系统原生：UIActivityViewController、Social Framework
友盟（第三方分享平台）
案例：小程序分享blog.csdn.net/z929118967/…

如果App分享类型需要支持多媒体(声音、视频、文件等）,需要支持的平台很多，推荐使用友盟分享。

I 系统原生: UIActivityViewController

1.1 支持的分享平台

iOS8之后App可以通过Share Extension提供分享入口，例如微信App的Share Extension对应的平台ID是@"com.tencent.xin.sharetimeline"。

可通过completionWithItemsHandler回调获取本机可用的Share Extension的bundle Id 。

隐藏默认的平台


    activityVC.excludedActivityTypes = @[UIActivityTypeOpenInIBooks,UIActivityTypeAirDrop];

支持的平台：

typedef NSString * UIActivityType NS_TYPED_EXTENSIBLE_ENUM;

UIKIT_EXTERN UIActivityType const UIActivityTypePostToFacebook     API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToTwitter      API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToWeibo        API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;    // SinaWeibo
UIKIT_EXTERN UIActivityType const UIActivityTypeMessage            API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeMail               API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePrint              API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeCopyToPasteboard   API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAssignToContact    API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeSaveToCameraRoll   API_AVAILABLE(ios(6.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAddToReadingList   API_AVAILABLE(ios(7.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToFlickr       API_AVAILABLE(ios(7.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToVimeo        API_AVAILABLE(ios(7.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypePostToTencentWeibo API_AVAILABLE(ios(7.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeAirDrop            API_AVAILABLE(ios(7.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeOpenInIBooks       API_AVAILABLE(ios(9.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeMarkupAsPDF        API_AVAILABLE(ios(11.0)) __TVOS_PROHIBITED;
UIKIT_EXTERN UIActivityType const UIActivityTypeSharePlay          API_AVAILABLE(ios(15.4)) __TVOS_PROHIBITED;

1.2 设置回调block，获取分享相关信息

    //设置回调block，获取分享相关信息
    
    UIActivityViewControllerCompletionWithItemsHandler myBlock = ^(UIActivityType __nullable activityType, BOOL completed, NSArray * __nullable returnedItems, NSError * __nullable activityError) {

           

           if (completed){

               NSLog(@"分享完成：%@",activityType);
               //分享完成：com.tencent.xin.sharetimeline
           }

       };
    
    activityVC.completionWithItemsHandler = myBlock;

1.3 案例

- (void)textToShare{
    
    NSString *textToShare = @"公众号：iOS逆向";

    UIImage *imageToShare = [UIImage imageNamed:@"icon"];
        
    NSURL *urlToShare = [NSURL URLWithString:@"https://blog.csdn.net/z929118967?type=blog"];


    NSArray *activityItems = @[textToShare, imageToShare, urlToShare];

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



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


}
