Objective-C将NSData转换为NSString [英] Objective-C Convert NSData to NSString

问题描述

以下是我尝试将NSData转换为NSString但代码返回程序接收信号：SIGABRT的代码。

Here are the code I tried to convert NSData to NSString but the program return "Program received signal:SIGABRT".

NSString *string= [NSString stringWithUTF8String:[data bytes]];

OR

NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

还有其他更好的方法吗？

Is there any other better way to do it?

推荐答案

这里有一个很高的评价 - 投票答案，说明如何做到这一点。简而言之：

Here's a highly up-voted answer that shows how to do it. In a nutshell:

NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

由于发送 [数据字节] <，第一个想法看起来像是失败了/ code>。 stringWithUTF8String没有为void *做好准备。第二个想法看起来好像应该有效，即使输入为零。

The first idea looks like a fail because of sending [data bytes]. stringWithUTF8String isn't prepared for a void *. The second idea looks as if it should work, even with nil input.
