NSString 与C++ string字符串的互转（转）

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