运行测试用例时 CocoaLumberJack XCTest 链接器错误

Question

When using CocoaLumberJack with XCTest, I get an error that it cannot find the DDLog.h . I've tried changing it to <CocoaLumberjack/DDLog.h> with no luck. The project compiles and runs fine with LumberJack working in the iOS Simulator, but when I run it for the unit testing target, I get this error (See Screenshot).

Here is my -Prefix.pch

  #import <Availability.h>

  #ifndef __IPHONE_5_0
  #warning "This project uses features only available in iOS SDK 5.0 and later."
  #endif

  #ifdef __OBJC__
      #import <UIKit/UIKit.h>
      #import <Foundation/Foundation.h>
      #import <CoreData/CoreData.h>
      #import <CocoaLumberjack/DDLog.h>
      #import "Utilities.h"
  #endif


  #ifdef DEBUG
  static const int ddLogLevel = LOG_LEVEL_VERBOSE;
  #else
  static const int ddLogLevel = LOG_LEVEL_ERROR;
  #endif

Error:

I've linked the libraries to to the tests target also as shown below with the libPods.a .

Why won't LumberJack link properly when running the TestCases? Is there something else I need to add to the TestTarget for it to link properly?

Answer 1

I was able to resolve the issue by removing the customizations to the -Prefix.pch file and reformat the podfile to use targets. I had to move the

 #import "DDLog.h"

and

#ifdef DEBUG
static const int ddLogLevel = LOG_LEVEL_VERBOSE;
#else
static const int ddLogLevel = LOG_LEVEL_ERROR;
#endif

into a `Utility.h' class.

The podfile was rebuilt to link both targets:

platform :ios, '7.0'

def common_pods
    pod 'CocoaLumberjack'
    pod 'HexColors'
end

target :MyApp do
    common_pods
end

target :MyAppTests do
    common_pods
end

I also had to remove the libPods.a from both targets since it would no longer be built. Instead libPods-MyApp.a and libPods-MyAppTests.a are built with the new podfile configuration.

You have to enable Pods configuration in your project → project settings → info → configurations:
