iOS共享GIF（动画图像）不工作 [英] iOS Share GIF (animated image) not Working

问题描述

我想要找到解决问题的方法已经差不多2天了，但是我没有成功，我想在Facebook，Twitter，Email，WhatsApp上分享GIF（动画图像），使用 UIActivityViewController。

这是我的代码：

  NSURL * imagePath = [NSURL URLWithString：@http：//sth.gif]; 
 NSData * animatedGif = [NSData dataWithContentsOfURL：imagePath]; 
 
 NSArray * sharingItems = [NSArray arrayWithObjects：animatedGif，stringToShare，nil]; 
 UIActivityViewController * activityVC = [[UIActivityViewController alloc] initWithActivityItems：sharingItems applicationActivities：nil]; 
  

当我分享电子邮件的动画和它的工作完美，但在Twitter，Facebook，whatsApp Gifs不是动画和它像一个图像...
我已经阅读所有关于相同问题的堆栈溢出问题像这个或此或

解决方案

迄今为止，基于日期研究发现： p>

TWITTER ：要在Twitter上分享一个GIF，必须使用twitter API并创建一个多部分请求来实现目标，并且其工作非常好。 p>

FACEBOOK ：我在Facebook上分享了一些GIF，使用 FACEBOOKSHAREKIT ，但我不知道为什么有时GIF是动画的，有时不是。

INSTAGRAM ：分享gif在Instagram上，必须将GIFS转换为MP4（或者Instagram接受的任何其他视频格式），然后将其保存到相机胶卷中，然后分享它，它的扭曲很小，但其工作非常好。

WHATSAPP ：它不支持GIF。

为了做到这一切，我无法使用UIActivityViewController ，因此决定创建自定义共享页面。如果有人知道要添加的内容，请帮助我和他人告诉我（特别是关于Facebook）。
提前感谢

It's been almost 2 days that i'm looking to find a solution to my problem but i wasn't successful , i want to share GIF (animated image) on Facebook, Twitter, Email, WhatsApp , using "UIActivityViewController".

This is my code :

NSURL *imagePath = [NSURL URLWithString:@"http://sth.gif"];
NSData *animatedGif = [NSData dataWithContentsOfURL:imagePath];

NSArray *sharingItems = [NSArray arrayWithObjects: animatedGif,stringToShare, nil];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];

When i share in Email its animated and its working perfect , but in Twitter , Facebook , whatsApp Gifs are not animated and its like an image ... I already read all Stack-overflow questions about the same problem Like this or this or this but its not working for me.

解决方案

So far base on days research found out that :

TWITTER : For share a GIF on twitter had to use twitter API and create a multipart request to achieve the goal and its working very well.

FACEBOOK : I did share some GIF on Facebook using FACEBOOKSHAREKIT , but i don't know why sometimes Gifs are animated, sometimes not.

INSTAGRAM : To share gif on Instagram had to convert GIFS to MP4 (or any other video formats accepted by Instagram) then save it into camera roll then share it , It is little twisted but its working very well.

WHATSAPP : It not supporting GIF at all.

To do all of this i couldn't use "UIActivityViewController" , so decided to create a custom share page. if anybody know something to add here , to help me and others please tell me (especially about Facebook). Thanks in advance
