我问的原因是它在没有旗帜的情况下建立得很好 但是,如果我添加标志,它会引发一堆错误:

显然是来自Parse SDK的。
然而,自their guide中所述,我想知道是否可以省略它。
我确实看到其他人遇到此问题,some saying -force_load
会解决此问题,但我不确定-ObjC
和-force_load
到底是做什么的,所以我不知道如何使用它。
怀疑我是否遗漏了任何框架,因为它没有标志就构建好了?
更新:
我找到了如何使用-force_load
here。但是,如果有人可以帮助解释-ObjC
和-force_load
标志的内容,我们仍会感激不尽。
要使用的链接器标志应为-force_load libGoogleAdMobAds.a
而不是-ObjC
。

您还需要链接:
Social.framework
Accounts.framework
转到项目构建阶段 - >链接二进制文件库并添加它们。如果您已经拥有它们,请尝试将其删除并重新添加。
我有这个问题,我添加了这些,它已修复。
