NSMutableString到char *

Question

Hot我可以将NSMutableString转换为char *？

e.g。

NSString* someval = @"This is a test.";
NSMutableString *temp = [NSMutableSTring stringWithString:someval];
char * temp2 = ????Not sure what to do here???;

Answer 1

使用-UTF8String方法：

NSString* someval = @"This is a test.";
NSMutableString *temp = [NSMutableString stringWithString:someval];
const char * temp2 = [temp UTF8String];
