我正在构建一个iPhone应用程序,并坚持以下几点:
unsigned char hashedChars[32];
CC_SHA256([inputString UTF8String], [inputString lengthOfBytesUsingEncoding:NSASCIIStringEncoding], hashedChars);
NSData *hashedData = [NSData dataWithBytes:hashedChars length:32];
NSLog(@"hashedData = %@", hashedData);
日志显示如下:
hashedData = <abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh>
但是我需要将hashedData转换为如下所示的NSString:
NSString *someString = @"abcdefghabcdefghabcdefghabcdefghabcdefghabcdefghabcdefghabcdefgh";
因此,基本上结果需要像hashedData一样,除了我不希望尖括号和两者之间有空格。
最佳答案
使用NSString initWithData:encoding:方法。
NSString *someString = [[NSString alloc] initWithData:hashedData encoding:NSASCIIStringEncoding];
(编辑以回复您的评论:)
在这种情况下,约书亚的答案确实有帮助:
NSCharacterSet *charsToRemove = [NSCharacterSet characterSetWithCharactersInString:@"< >"];
NSString *someString = [[hashedData description] stringByTrimmingCharactersInSet:charsToRemove];
关于iphone - NSData显示为字符串,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/2653288/
