Question

在我的iphone应用程序中，我正在尝试从Twitter获取推文。

我从以下链接获得了一个编码示例：

https://github.com/mattgemmell/MGTwitterEngine

但是当我实施这个例子时，我收到了以下警告：

Ld build/Debug-iphonesimulator/XAuthTwitterEngineDemo.app/XAuthTwitterEngineDemo normal i386

可以做些什么？

Answer 1

您可以从此url获取推文，然后返回xml，您可以从中解析推文。

Answer 2

您遇到的问题是MGTwitterEngine项目是针对Cocoa的，因此它链接的框架和库是仅限MacOS的二进制文件。具体来说，它们是：libxml2和AppKit。

为了将其移植到iOS，您应该创建一个新的iOS项目，导入所有源代码，并链接到UIKit（这应该已经没问题）和iOS版本的libxml2（你可以找到它） “添加现有框架”）....
