objective-c - 新 Three20 构建错误

Question

我刚刚将我的项目升级到最新的 Three20 Build。编译时出现以下错误：

Undefined symbols:
  "___restore_vfp_d8_d15_regs", referenced from:
  +[TTEntityTables(TTSingleton) sharedInstance] in libThree20Core.a(TTEntityTables.o)
  +[TTEntityTables(TTSingleton) releaseSharedInstance] in libThree20Core.a(TTEntityTables.o)
  +[TTEntityTables(TTSingleton) allocWithZone:] in libThree20Core.a(TTEntityTables.o)
  "___save_vfp_d8_d15_regs", referenced from:
  +[TTEntityTables(TTSingleton) sharedInstance] in libThree20Core.a(TTEntityTables.o)
  +[TTEntityTables(TTSingleton) releaseSharedInstance] in libThree20Core.a(TTEntityTables.o)
  +[TTEntityTables(TTSingleton) allocWithZone:] in libThree20Core.a(TTEntityTables.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status

有人知道这里发生了什么吗？

在此先感谢，卢卡斯
