在 Objective-c 中将 NSData 转换为 int [英] Transform NSData to int in Objective-c

问题描述

我想在 Objective-c 中将 NSData 转换为 int.

I would like to transform NSData to int in Objective-c.

在下面的代码中，index2"是15"，而value"是0".(NSLog 说15,0".)

In the following code, "index2" is "15", but "value" is "0". (NSLog says "15,0".)

准确地说，值"必须是15".

To be exact, "value" must be "15".

 NSString *index = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
 NSString *index2 = [index stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
 int value = [index2 intValue];
 NSLog(@"%@,%d",index2,value);

你能告诉我如何解决这个问题吗?

Could you tell me how to solve this problem?
