iOS 自带的分享功能

1. 导入Social.framework 库

2. 代码

- (void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event

{

    //分享的标题

    NSString *text =@"分享的标题。";

    //分享的图片

  //  UIImage *image= [UIImage imageNamed:@"分享的图片.png"];

    //分享的url

    NSURL*url = [NSURLURLWithString:@"分享的url"];

    //把分项的文字, 图片, 链接放入数组

    NSArray*activityItems =@[text,image,url];

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

    //不出现在活动项目

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

//弹出分享的页面

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

    // 分享后回调

    activityVC.completionWithItemsHandler= ^(UIActivityType  _NullableactivityType,BOOLcompleted,NSArray*_NullablereturnedItems,NSError*_NullableactivityError) {

        if(completed) {

            NSLog(@"completed");

            //分享成功

        }else  {

            NSLog(@"cancled");

            //分享取消

        }

    };

}
