NSString 与C++ string字符串的互转（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];
NSLog(filepath);

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];
