objective-c - Objective-C - 将 char[] 转换为十六进制格式的 NSString

Question

我有一个问题，我需要将 char[] 转换为 String，十六进制格式

例子

Nsstring * result;
char[4]={0x01,0x02,0x03,0x04};

///    convert  --   char[] -> Nsstring in Hex format

Nslog(@"%@",result);

预期输出:“01020304”

谢谢

试试这个:

NSMutableString * result = [[NSMutableString alloc] init];
char cstring[4]={0x01,0x02,0x03,0x04};
///    convert  --   char[] -> Nsstring in Hex format
int i;
for (i=0; i<4; i++) {
    [result appendString:[NSString stringWithFormat:@"%02x",cstring[i]]];
}

NSLog(@"%@",result);
[result release];
