objective-c - 一个项目的 xcode 4.6（xcode 崩溃）后无法重构（其他项目运行良好）

Question

我做了什么：

当 xcode 似乎试图下载 10.8x 文档或其他内容时，我正在重构。如何恢复 xcode 尚未下载的内容？

我已经清理了项目，清理了快照，删除了快照目录。

这个项目在尝试重构时使 xcode 挂起。其他项目没有这个问题。

如果我想重新安装 xcode，我必须重新下载吗？这是错误信息

天啊！这很难追踪。我遇到了同样的问题，但我设法找到了它（至少对我来说）。

当您 Refactor > Rename... 并且您的源有一个包含 @literal 构造的宏时，就会发生崩溃。

崩溃示例 1：

STAssertEqualObjects([currencyFormatter numberFromString:@" $100. "], @100.00, nil);
STAssertEqualObjects([currencyFormatter numberFromString:@"100"], @100.00, nil);

固定：

NSNumber *x100_00 = @100.00;
STAssertEqualObjects([currencyFormatter numberFromString:@" $100. "],x100_00, nil);
STAssertEqualObjects([currencyFormatter numberFromString:@"100"], x100_00, nil);

崩溃示例 2：

STAssertEqualObjects(isActive, @YES, nil);

修正：成功

NSNumber *xYES = @YES;
STAssertEqualObjects(isActive, xYES, nil);

崩溃示例 3：

NSParameterAssert(([@[@"Option 1", @"Option 2"] containsObject:shareType]));

固定：

- (NSArray *)GMS_shareTypes
{
    return @[@"Option 1", @"Option 2"];
}

…

NSParameterAssert([self.GMS_shareTypes containsObject:shareType]);

正如其他人所说，我认为实际上您应该尝试准确追踪代码的哪一部分导致重构失败。有条不紊，并尝试确定问题所在。那时，您可以开始找出导致它的原因。

当我过去遇到重构问题时，彻底清理已解决（如果您还没有这样做，清除 DerivedData 也可能会有所帮助）。

很难解决，但以下是崩溃报告中的一些线索：

似乎您有一个扩展为未正确解析的宏。我的意思是它会生成一个错误的令牌（例如无限长）
看起来它在复杂的按位逻辑和移位语句之后的某个地方
也许在一个街区内。

你能检查你的宏：

去掉它
或替换为内联
或者有时只是复制粘贴或重写它（错误的不可见字符）。

这可能会修复你的铅。告诉我。
