objective-c - 来自设备上的测试程序的EXC_BAD_ACCESS

Question

在模拟器中测试时，效果很好，而在设备中测试时，出现以下错误和警告

Current language:  auto; currently objective-c++
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
Program received signal:  “EXC_BAD_ACCESS”.

请问如何改写

Answer 1

很难说为什么在设备上而不是模拟器上出现错误。至于您没有找到该符号的警告，可以按照以下说明解决:

libXcodeDebuggerSupport.dylib is missing in iOS 4.2.1 development SDK

特别

cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols

和

ln -s ../../4.2\ \(8C134\)/Symbols/Developer/ Developer

回到您的问题，您可以在以下位置阅读有关如何调试EXC_BAD_ACCESS的信息

您还应该启用Guard Malloc

(在 EXC_BAD_ACCESS on device, but fine on Simulator找到了)

谢谢楼弗朗哥-我给你投了赞成票:)
