Question

由于某些原因，当我添加＆＃39; - ObjC＆＃39;时，我收到链接器错误到我的Xcode项目中的其他链接器标志。如果我删除此标志，我将无法加载其中一个表视图并收到以下错误：

*** Assertion failure in -[AMTableView _configureCellForDisplay:forIndexPath:], /SourceCache/UIKit_Sim/UIKit-3318.16.14/UITableView.m:7344
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'

我是否相信这是由缺乏-ObjC引起的？

所以当我重新添加标志时（它实际上是用 - $（继承）引入的，因为cocoapods告诉我把它带进去），我得到一个链接器错误：

clang: error: unsupported option '--ObjC'

我错过了什么？ --ObjC标志究竟发生了什么？

问题是链接器标志的拼写错误。我刚刚检查了我的项目，它应该是＆＃39; -ObjC＆＃39;一个短划线，但不是两个。
以下是有关旗帜的其他信息：
https://developer.apple.com/library/ios/qa/qa1490/_index.html
这是Apple的描述：

将-ObjC选项传递给链接器会导致它加载所有成员实现任何Objective-C类或类别的静态库。这将拾取任何类别方法实现。但它可以做到结果可执行文件更大，并可能拾取不必要的对象。因此，默认情况下不启用

clang：错误：不支持的选项'--ObjC'
