我一直试图让代码覆盖率适用于iPhone模拟器,并始终获得0%的覆盖率.以下是配置详细信息和我尝试过的步骤.

组态

Xcode 3.2.5/iOS 4.1和iOS 4.2/Mac 10.6/GCC 4.2应用程序UICatalog

脚步

• 启用"生成测试覆盖率文件"
• 启用"仪器程序流程"
• 将" -lgcov" 添加到"其他链接标志"
• UIApplicationExitsOnSuspend Info.plist中的标志设置为true

结果

我生成了.gcda文件,但覆盖率始终显示为0%.

尝试了设置

1. 将GCC更改为4.0和4.2.当我尝试将GCC更改为4.0时,我得到26个构建错误.

2. 设置环境变量

   (const char *prefix = "GCOV_PREFIX";
   const char *prefixValue = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] cStringUsingEncoding:NSASCIIStringEncoding]; // This gets the filepath to the app's Documents directory
   const char *prefixStrip = "GCOV_PREFIX_STRIP";
   const char *prefixStripValue = "1";
   setenv(prefix, prefixValue, 1); // This sets an environment variable which tells gcov where to put the .gcda files.
   setenv(prefixStrip, prefixStripValue, 1); // This …
