iOS UIActivityViewController 分享P

本文主要分享UIActivityViewController使用的小坑！！

---

如果分享的是二进制文件数据，不会出现微信、QQ、CSDN等分享，并且左上方不会自动解析文件名字和缩略图

    NSData *data = [NSData dataWithContentsOfURL:self.fileURL];
    NSArray*activityItems = @[data];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
    [[UIApplication sharedApplication].delegate.window.rootViewController 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(@"分享完成");
        }else {
            NSLog(@"分享未完成");
        }
    };

不出现第三方app的分享效果图
