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];
