我不知道发生了什么，因为我对 Objective C 和 IOS 开发还很陌生。

当我尝试使用默认测试框架运行我的测试时，出现以下错误:

        ..../Pods/Expecta/src/matchers/EXPMatchers+beCloseTo.m:4:1: 
Class 'EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher' 
    defined without specifying a base class

以下代码片段产生了问题(但它不是我的，我相信它是我通过 pods 使用的库之一的片段):

#import "EXPMatchers+beCloseTo.h"
#import "EXPMatcherHelpers.h"

EXPMatcherImplementationBegin(_beCloseToWithin, (id expected, id within)) {
  prerequisite(^BOOL{
    return [actual isKindOfClass:[NSNumber class]] &&
        [expected isKindOfClass:[NSNumber class]] &&
        ([within isKindOfClass:[NSNumber class]] || (within == nil));
  });

  match(^BOOL{
        double actualValue = [actual doubleValue];
        double expectedValue = [expected doubleValue];

        if (within != nil) {
            double withinValue = [within doubleValue];
            double lowerBound = expectedValue - withinValue;
            double upperBound = expectedValue + withinValue;
            return (actualValue >= lowerBound) && (actualValue <= upperBound);
        } else {
            double diff = fabs(actualValue - expectedValue);
            actualValue = fabs(actualValue);
            expectedValue = fabs(expectedValue);
            double largest = (expectedValue > actualValue) ? expectedValue : actualValue;
            return (diff <= largest * FLT_EPSILON);
        }
  });

  failureMessageForTo(^NSString *{
    if (within) {
      return [NSString stringWithFormat:@"expected %@ to be close to %@ within %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected), EXPDescribeObject(within)];
    } else {
      return [NSString stringWithFormat:@"expected %@ to be close to %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected)];
    }
  });

  failureMessageForNotTo(^NSString *{
    if (within) {
      return [NSString stringWithFormat:@"expected %@ not to be close to %@ within %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected), EXPDescribeObject(within)];
    } else {
      return [NSString stringWithFormat:@"expected %@ not to be close to %@",
              EXPDescribeObject(actual), EXPDescribeObject(expected)];
    }
  });
}
EXPMatcherImplementationEnd

我的 POD 文件如下所示:

platform :ios, 6.0
pod 'RestKit', '~> 0.20.0rc'

# Include optional Testing and Search components
pod 'RestKit/Testing', '~> 0.20.0rc'
pod 'RestKit/Search', '~> 0.20.0rc'


target :MTPROJTESTS do
  pod 'Expecta',     '~> 0.2.3'   # expecta matchers
  # pod 'Specta',      '~> 0.1.11'  # specta bdd framework
end

更新 cocoa pod 和 EXPECTA 后出现新错误:ld:找不到 -lPods-test 的库 clang:错误:链接器命令失败，退出代码为 1(使用 -v 查看调用)

错误:

我希望有人知道:)

最佳答案

关于新的链接器错误:Xcode 喜欢为测试添加一个新的构建目标，因此请确保所有适当的文件(例如，您的 .m 源文件、您的静态库、您的框架)都设置为包含在测试构建目标。您可以通过在 Project Navigator 中选择文件并查看 File Inspector Pane 中的“Target Membership”部分来执行此操作；确保选中测试构建目标的框。此外，在您的项目设置中，您可以选择测试构建目标并转到构建阶段并查看“将二进制文件与库链接”以确保链接了适当的库。
