  1.C++ string 转换为 NSString 
 
　　 std::string str("hello");
    // NSString *str = [NSString stringWithString:str.c_str()];
   　　 NSString *ocstr = [NSStringstringWithCString:str.c_str() encoding:NSUTF8StringEncoding];
 
 
　　 NSString *istr = [NSString stringWithString:@"zsh"];
    str = [istr cStringUsingEncoding:NSUTF8StringEncoding];
 
 2. NSString 转换为C 字符串
 
    const char* destDir = [filepath UTF8String];
   //  NSURL *soundUrl=[[NSURL alloc] initFileURLWithPath:s];
 
 
3. const char* to NSString
 
   char *str ="abc";
   NSString *s = [NSString stringWithUTF8String:str];
 
 　 NSString *path = [[NSBundle mainBundle]pathForResource:@"nokia" ofType:@"mp3"];
    char *tempPath = (char*)malloc(sizeof(path)+1);
   
    NSString *soundPath = [[NSBundle mainBundle] pathForResource:@mp3"];
     
    NSString *dirStr = [NSString stringWithFormat:@"%s",path];
    NSString *filepath = [[NSBundle mainBundle] pathForResource:dirStr ofType:nil];
    NSLog(filepath);
