ios - Xcode 模块导入错误

Question

我正在尝试将 AMBubbleTableViewController 模块添加到我的应用程序 ( https://github.com/andreamazz/AMBubbleTableView )，并且我按照说明进行操作，但我遇到了很多错误，我不知道为什么。

这些是错误，知道吗？

Undefined symbols for architecture x86_64:


"_AMOptionsBubbleDetectionType", referenced from:
      -[Chat viewDidLoad] in Chat.o
  "_AMOptionsBubblePressEnabled", referenced from:
      -[Chat viewDidLoad] in Chat.o
  "_AMOptionsBubbleSwipeEnabled", referenced from:
      -[Chat viewDidLoad] in Chat.o
  "_OBJC_CLASS_$_AMBubbleTableViewController", referenced from:
      _OBJC_CLASS_$_Chat in Chat.o
  "_OBJC_METACLASS_$_AMBubbleTableViewController", referenced from:
      _OBJC_METACLASS_$_Chat in Chat.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

这是我的代码:

- (void)viewDidLoad {
// Bubble Table setup

[self setDataSource:self]; // Weird, uh?
[self setDelegate:self];
[self setTitle:@"Chat"];

// Dummy data
self.data = [[NSMutableArray alloc] initWithArray:@[

如果包含您正在使用的特定定义的源文件没有被编译，尽管它们的声明在您正在导入的头文件中，您会经常看到这种链接器错误。

您可以通过将适当的源文件添加到项目的“编译源”构建阶段来解决此问题。

在这种特殊情况下，您需要包含 AMBubbleTableViewController.m 和 AMBubbleGlobals.m 文件。
