只需更新
Xcode到4.3,现在我无法建立我的应用程序.我收到这个错误：
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang Failed with exit code 254
有人有这个问题吗？这可能只是一个编译设置,但我不知道在哪里看.
当然,错误包括整个堆栈转储,但是为了简洁起见,我没有包括这个.我希望有人会知道“退出代码254”是什么.试图搜索它,但找不到任何东西.
以下是整个输出：

UPDATE
所以我注意到转储是指特定类(SCheckBox.m)中的代码上的特定行.
这是一个init方法.我检查了方法,但找不到任何错误.但是,如果我将方法中的所有内容都注释出来,并返回nil,则代码编译.我经历了每一行的取消注释,直到我收到错误.导致问题的错误是：
[super.inputField addSubview:_checked];
我打算使用“自我”而不是“超级”(这是我的错字).但是super实际上有一个inputField属性.它不会在子类中重新定义或覆盖.所以访问’super.inputField’vs’self.inputField’应该访问完全相同的东西(并且在升级Xcode之前).好的,所以改变“超级”到“自我”确实解决了这个问题.
我现在的问题是：为什么？
解决方法
我通过尝试通过NSLog输出一个就地操作(返回void)的结果,在Xcode 4.3.2中设法触发了这个问题.
在我的情况下,我想做的是：
NSLog(@"result = %@",[array filterUsingPredicate:predicate]);
filterUsingPredicate：是一个返回void的就地方法的事实似乎触发了这个编译器错误.有趣的是,Xcode的类似错误检测不会在其上.
将其更改为正确版本： –
NSLog(@"result = %@",[array filteredArrayUsingPredicate:predicate]);
工作正常,解决问题！
