關於系統自帶的分享功能 主要是在與這個類 UIActivityViewController
先上效果圖

然後呢 直接上程式碼 大家都懂的 ^&^

//分享的標題
 NSString *textToShare = @"分享的標題。";
//分享的圖片 
 UIImage *imageToShare = [UIImage imageNamed:@"312.jpg"];
 //分享的url
 NSURL *urlToShare = [NSURL URLWithString:@"http://www.baidu.com"];
 //在這裡呢 如果想分享圖片 就把圖片新增進去  文字什麼的通上
 

 NSArray *activityItems = @[textToShare,imageToShare, urlToShare];
 UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
  //不出現在活動專案
activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll];
[self
 
 presentViewController:activityVC animated:YES completion:nil];
 // 分享之後的回撥
    activityVC.completionWithItemsHandler = ^(UIActivityType  _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {
        if (completed) {
            NSLog(@"completed"
 
);
            //分享 成功
        } else  {
            NSLog(@"cancled");
            //分享 取消
        }
    };

就是這麼的簡單
