我做了什么：
当xcode似乎试图下载10.8x文件或什么时，我正在重构。如何恢复xcode没有下载的内容？
我已经清理了项目，并清理了快照，删除了快照目录。
这个项目在尝试重构时会使xcode挂起。其他项目没有这个问题。
如果我想重新安装xcode，我是否需要重新下载？ 这是错误消息

圣牛！这很难追查。我遇到了同样的问题，但我设法追踪它（至少对我而言）。
重构＆gt;时发生崩溃重命名...并且您的源代码包含一个包含@ literal构造的宏。
崩溃示例1：
STAssertEqualObjects([currencyFormatter numberFromString:@" $100. "], @100.00, nil);
STAssertEqualObjects([currencyFormatter numberFromString:@"100"], @100.00, nil);
修正：
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]));
修正：
- (NSArray *)GMS_shareTypes
{
return @[@"Option 1", @"Option 2"];
}
…
NSParameterAssert([self.GMS_shareTypes containsObject:shareType]);
答案 1 :(得分：1)
正如其他人所说，我认为你应该尝试准确地追踪代码的哪一部分导致重构失败。要有条不紊，并尝试确定问题所在。那时，你可以开始解决导致它的原因。
当我过去曾经有过重构问题时，一个完整的清理工具已将其整理出来（如果您还没有完成，则清除DerivedData也会有所帮助。）
答案 2 :(得分：1)
难以解决，但这是崩溃报告的一些线索：
似乎您的宏扩展为未正确解析的内容。我的意思是它会生成一个错误的令牌（例如无限长）
在复杂的按位逻辑和转换语句之后看起来它位于
可能位于块。
你可以检查你的宏：
将其删除
或替换为内联
或者有时只是复制粘贴或重写它（错误的隐形字符）。
这可能会修复你的pb。 告诉我。
