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);
