xcode - Apple LLVM编译器3.1错误

Question

刚刚将Xcode更新为4.3，现在无法构建我的应用程序。我收到此错误:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 254

还有其他人有这个问题吗？它可能只是一个编译设置，但我不确定要看哪里。

当然，该错误包括整个堆栈转储，但是为了简洁起见，我没有将其包括在内。我希望有人会知道“退出代码254”是什么。尝试搜索，但找不到任何东西。

这是整个输出:

更新
因此，我注意到转储引用了特定类(SCheckBox.m)中代码的特定行。
它采用init方法。我已经检查了该方法，但找不到任何错误。但是，如果我注释掉方法中的所有内容并返回nil，则代码将编译。我仔细检查了每一行，直到得到错误为止。导致问题的错误是这样的:

[super.inputField addSubview:_checked];

我原本打算使用“自我”而不是“ super ”(这对我来说是错别字)。但是super实际上确实具有inputField属性。它不会在子类中重新定义或覆盖。因此，访问“super.inputField”与“self.inputField”应该访问完全相同的东西(在升级Xcode之前也是如此)。好的，因此将“ super ”更改为“自我”确实可以解决问题。

我现在的问题是:为什么？

Answer 1

我设法通过尝试通过NSLog输出就地操作的结果(返回void)在Xcode 4.3.2上触发了此问题。

就我而言，我想做的是:

NSLog(@"result = %@", [array filterUsingPredicate:predicate]);

filterUsingPredicate:是返回 void的就地方法的事实似乎触发了此编译器错误。有趣的是，Xcode的按需输入错误检测没有被接受。

将此更改为正确的版本:-

NSLog(@"result = %@", [array filteredArrayUsingPredicate:predicate]);

效果很好，可以解决问题!
