将NSString转换为const char*

Question

我想将nsstring值转换为const char*.

NSString *s = @"??????????????"; //Hebrew characters
const char *t = [s cStringUsingEncoding:NSUTF8StringEncoding];
NSLog(@"\n str = %s",t);

控制台显示如下"◊ô◊õ◊õ◊¢◊◊◊◊◊◊◊◊◊◊◊◊◊◊◊◊◊

如何将实际的NSString值转换为const char*？

谢谢,loganathan

Answer 1

这只是因为%sin NSLog表示ASCII字符串(简单地说是普通C 8位字符串),而不是UTF8.

尝试以下怎么样？:

NSString *s = @"??????????????"; //Hebrew characters
NSLog(@"\n str = %@",s);

您还可以注销UTF16数组:

const wchar_t *t = (const wchar_t*)[s cStringUsingEncoding:NSUTF16StringEncoding];
NSLog(@"\n str2 = %S",t);
