NSString 与 C++ string字符串的互转

  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);
