使用 Hamcrest 断言在 Xcode 3.2.4、iOS 4.1 SDK 上进行单元测试失败

Question

我们使用 iOS 4.1 SDK 升级到 Xcode 3.2.4，现在我们的测试失败了。

首先，由于处理命令输出时发生内部错误：-[XCBuildLogCommandInitationSectionRecorder endMarker]：无法识别的选择器发送到实例0x201aa7200，然后我们使用了苹果论坛建议的补丁（http://gist.github.com）。 com/586296），现在测试在第一个 Hamcrest 断言上失败。

NSNumber * c1 = ...
NSNumber * c2 = ...
assertThat(c1, is(c2))

这是日志：

有人以前看过吗？它在 3.1.3 SDK 上完美运行。

Answer 1

通过使用最新的 OCHamcrest 作为静态库而不是框架并将 -lstdc++ 添加到其他链接器标志，可以修复此问题。

希望能节省某人的时间。
