如何通过Unity iOS应用程序在Twitter上分享图片和链接

在游戏引擎和游戏开发方面，Unity这一技术看起来是不可多得的，因为它不仅是最受欢迎和强大的游戏引擎，它具有用于开发iOS和游戏的优秀视觉编辑器，同时也具有很多功能，功能和社区的问题处理以及良好的定价选项。 毫无疑问，Unity被认为是最好的构建iOS和Android游戏和应用程序的引擎。
今天在本教程中，我正在分享一个与iOS应用程序相关的主题，帮助您轻松地从应用程序分享图片或链接到twitter。 而分享图像不是一项重大任务，而是包含iOS，用户必须首先上传图像或先在设备路径上写入图像，然后从该路径读取图像，因为iOS中不存在资源文件夹。 所以借助下面的代码，您可以轻松地将图像读取和写入设备路径。
让我们看看如何实现：
首先在Twitter上创建一个应用程序，并保存应用程序的消费者密钥，秘密密钥，媒体URL和Tweet URL。
那么为了在Twitter上分享，用户必须在Twitter上登录。 所以让我们使用下面提到的代码登录用户。
现在，我们创建三个UI按钮。
1.Twitter登录按钮//点击TwitterLogin
2.提交Pin Button //点击SubmitPin（）
3.Twitter分享按钮//在点击中调用Twitter（）。
并创建一个InputField来输入您在调用TwittterLogin（）函数后收到的PIN码。
 
1. InputFieldPin
启动Twitter登录按钮。 然后成功禁用登录按钮并启用输入框并提交按钮。 然后在成功登录后，启用“共享”按钮并禁用所有其他按钮
现在创建两个脚本：
TwitterHandller和
Twitter
