字符编码 CP037

正在将应用程序从 java 转换为 Objective-C，并遇到了有关字符编码的问题。

在java代码中，我试图转换的语句是：

byte[] instructions = input.getBytes("CP037");

我希望在objective-c中执行以下操作：

 const char *instructions = [input CP037];

但是“CP037”不作为编码存在，有谁知道如何克服？

Am converting an application from java to objective-c and have run into an issue around character encoding.

In the java code the statement am trying to convert is:

byte[] instructions = input.getBytes("CP037");

I was hoping to do the following in objective-c:

 const char *instructions = [input CP037];

However "CP037" doesn't exist as an encoding, does anyone know how to overcome?

最终到达那里：

 NSString *stringThatNeedsToBeEncoded = @"randomString";  
 CFDataRef encodedStringAsCFData = CFStringCreateExternalRepresentation(CFAllocatorGetDefault(), (CFStringRef)stringThatNeedsToBeEncoded, kCFStringEncodingEBCDIC_CP037, 0); 

 CFIndex bufferLength = CFDataGetLength(encodedStringAsCFData);  
 UInt8 *buffer = malloc(bufferLength);  
 CFDataGetBytes(encodedStringAsCFData, CFRangeMake(0, CFDataGetLength(encodedStringAsCFData)), buffer);

Got there in the end:

 NSString *stringThatNeedsToBeEncoded = @"randomString";  
 CFDataRef encodedStringAsCFData = CFStringCreateExternalRepresentation(CFAllocatorGetDefault(), (CFStringRef)stringThatNeedsToBeEncoded, kCFStringEncodingEBCDIC_CP037, 0); 

 CFIndex bufferLength = CFDataGetLength(encodedStringAsCFData);  
 UInt8 *buffer = malloc(bufferLength);  
 CFDataGetBytes(encodedStringAsCFData, CFRangeMake(0, CFDataGetLength(encodedStringAsCFData)), buffer);
