iOS 上支持调用C库来获取.app的Bundle路径，实现代码如下：

#include <CoreFoundation/CFBundle.h>

// Get a reference to the main bundle

CFBundleRefmainBundle=CFBundleGetMainBundle();

// Get a reference to the file's

URLCFURLRefimageURL=CFBundleCopyResourceURL(mainBundle,CFSTR("MyImage"),CFSTR("bmp"),NULL);

// Convert the URL reference into a string reference

CFStringRefimagePath=CFURLCopyFileSystemPath(imageURL,kCFURLPOSIXPathStyle);

// Get the system encoding method

CFStringEncodingencodingMethod=CFStringGetSystemEncoding();

// Convert the string reference into a C string

constchar*path=CFStringGetCStringPtr(imagePath,encodingMethod);

fprintf(stderr,"File is located at %s\n",path);
