iPhone - 将字符串转换为unsigned char

Question

我正在尝试从服务器解密字符串。

我希望以下部分中的字符串 -

unsigned char Cipher1[] = {My String};

我的字符串是

  

“194,75,26,184,223,124,164,170,161,213,135,46,160,5,82,46,56,44,244,116,37,20,181,65,49,243,172,203,32,188,168,54,46,207,126,14,111,24,39,131,185,13,​​58,105,32,168,77， 83,202,165,242,198,34,192,161,39,202,58,230,72,234,218,171,50,187,235,124,24,16,2,117,188,221,73,136,37,81,217,30,17,57,136,91,224,178,12,37,255"

如何解决这个问题。

提前感谢。

Answer 1

试试这个：

const unsigned char *string = (const unsigned char *) [MyString UTF8String];

Answer 2

如果您只是想将NSString转换为char *，请使用- (const char *)cStringUsingEncoding:(NSStringEncoding)encoding

const char *cipher1 = [myString cStringWithEncoding: NSUTF8StringEncoding];
