NSString 与C++ string字符串的互转

NSString 与C++ string字符串的互转

1.  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)+1);    
    NSString *soundPath=[[NSBundle mainBundle] pathForResource:@mp3"]; 
    
    NSString* dirStr = [NSString stringWithFormat:@"%s",path];
    NSString* filepath = [[NSBundle mainBundle] pathForResource:dirStr ofType:nil];

 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];
