在Xcode 5.0.2（XCTest）中为现有项目添加新的测试目标虽然在编译测试目标时成功，但不起作用。
我已经在这里搜索过但没有成功。
额外信息：
这是一款iOS应用
部署目标是7.0
它使用两个带有资源包的子项目（静态库）
这里有错误信息：
2014-03-19 11:31:06.509 MyProject[53196:70b] Error loading /Users/rodrigoarantes/Library/Developer/Xcode/DerivedData/IgnitEdu-dcshcxphrysxcqdftuszmgdoweuz/Build/Products/Debug-iphonesimulator/MyProjectTests.xctest/MyProjectTests: dlopen(/Users/rodrigoarantes/Library/Developer/Xcode/DerivedData/IgnitEdu-dcshcxphrysxcqdftuszmgdoweuz/Build/Products/Debug-iphonesimulator/MyProjectTests.xctest/MyProjectTests, 262): no suitable image found.

如何解决此错误？
非常感谢任何帮助。
