当你有一些话不是很好意思说的时候，就用0和1代替吧，只有专属的才能翻译出来哦。
你可以直接发送01数据给别人，鬼知道你说什么。。。哈哈哈
主要代码就是
NSMutableDictionary *binaryDic = [[NSMutableDictionary alloc] initWithCapacity:16]; [binaryDic setObject:@"0" forKey:@"0000"]; [binaryDic setObject:@"1" forKey:@"0001"]; [binaryDic setObject:@"2" forKey:@"0010"]; [binaryDic setObject:@"3" forKey:@"0011"]; [binaryDic setObject:@"4" forKey:@"0100"]; [binaryDic setObject:@"5" forKey:@"0101"]; [binaryDic setObject:@"6" forKey:@"0110"]; [binaryDic setObject:@"7" forKey:@"0111"]; [binaryDic setObject:@"8" forKey:@"1000"]; [binaryDic setObject:@"9" forKey:@"1001"]; [binaryDic setObject:@"A" forKey:@"1010"]; [binaryDic setObject:@"B" forKey:@"1011"]; [binaryDic setObject:@"C" forKey:@"1100"]; [binaryDic setObject:@"D" forKey:@"1101"]; [binaryDic setObject:@"E" forKey:@"1110"]; [binaryDic setObject:@"F" forKey:@"1111"]; if (binary.length % 4 != 0) { NSMutableString *mStr = [[NSMutableString alloc]init];; for (int i = 0; i < 4 - binary.length % 4; i++) { [mStr appendString:@"0"]; } binary = [mStr stringByAppendingString:binary]; } NSString *hex = @""; for (int i=0; i<binary.length; i+=4) { NSString *key = [binary substringWithRange:NSMakeRange(i, 4)]; NSString *value = [binaryDic objectForKey:key]; if (value) { hex = [hex stringByAppendingString:value]; } }
具体的还是请看代码吗。
