Nsdata到Objective-C中的nsstring [英] Nsdata to nsstring in objective-C

问题描述

大家好，

我知道这是非常简单直接但我一直在尝试使用Obj-C将NSData转换为NSString，但输出并不是我真正想要的。



我的NSData变量：

Hi All,
I know this is suppose to be very straight forward and simple but i have been trying to convert NSData to NSString using Obj-C but the outputs are not what I really wanted.

my NSData variable:

NSData *blockData = [NSData dataWithBytes:&data length:sizeof(data)];

我正在尝试在 NSLog中打印如下所示：

I'm trying to print it in NSLog like below:

NSLog(@"sneding block: %@", blockData);

输出就像：

the output is like:

018-06-13 08:05:18.641965-0400 sendData[3016:1171273] sneding: <0000e992 ffff0300 00884242 4242ffff ffff>

我需要输出为字符串或数字而不是十六进制，我在java中通过将byte []数组转换为字符串来完成它：Arrays.toString（byte [] ）输出类似于：[ - 24,14,60,103，-119,14，-118,12，-117,13,18,84,81，-118,10，-117,11，-22]



任何想法？

提前致谢



我尝试过：



我试图使用 NSUTF8StringEncoding

I need the output to be in string or numbers not hex, i have done it in java by converting byte[] array to string: Arrays.toString(byte[]) the output something like: [-24,14,60,103,-119,14,-118,12,-117,13,18,84,81,-118,10,-117,11,-22]

any ideas?
Thanks in advance

What I have tried:

I tried to use NSUTF8StringEncoding

NSString *str = [[NSString alloc] initWithData:blockData encoding:NSUTF8StringEncoding];//returns null

也试过 NSASCIIStringEncoding 没有运气

also tried NSASCIIStringEncoding with no luck

[[NSString alloc] initWithData:blockData encoding:NSASCIIStringEncoding];//returns ascii codes

推荐答案

你可以这样做：

You can do it like this:

NSMutableString * str = [NSMutableString string];
for (int i = 0; i<sizeof(data); i++)
{
    [str appendFormat:@"%d ", data[i]];
}

NSLog(@"%@",str);
