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];
