iOS基礎之路之NSString與Char相互轉換

    //char -> NSString

    char *charStr = "hello";

    NSString *ocStr = [NSString stringWithCString:charStr encoding:NSUTF8StringEncoding];

    //NSString ->char

    NSString *ocString  = @"HELLO";

    const char *charString = NULL;

    if ([ocString canBeConvertedToEncoding:NSUTF8StringEncoding]) {

        charString = [ocString cStringUsingEncoding:NSUTF8StringEncoding];

    }
