IOS 系统自带的分享功能之 UIActivityViewController

关于系统自带的分享功能 主要是在与这个类 UIActivityViewController
先上效果图

然后呢 直接上代码 大家都懂的 ^&^

//分享的标题
 NSString *textToShare = @"分享的标题。";
//分享的图片 
 UIImage *imageToShare = [UIImage imageNamed:@"312.jpg"];
 //分享的url
 NSURL *urlToShare = [NSURL URLWithString:@"http://www.baidu.com"];
 //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 = @[textToShare,imageToShare, urlToShare];
 UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
  //不出现在活动项目
activityVC.excludedActivityTypes = @[UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll];
[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) {
            NSLog(@"completed");
            //分享 成功
        } else  {
            NSLog(@"cancled");
            //分享 取消
        }
    };

就是这么的简单
