1.可以写一个字符串延展category

@implementation NSString (DubaiMD5)

+(NSString *) md5: (NSString *) inPutText

{

const char *cStr = [inPutText
UTF8String];

unsigned
char result[CC_MD5_DIGEST_LENGTH];

CC_MD5(cStr, strlen(cStr), result);

return [[NSString
stringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",

result[0], result[1], result[2], result[3],

result[4], result[5], result[6], result[7],

result[8], result[9], result[10], result[11],

result[12], result[13], result[14], result[15]

] lowercaseString];

}

@end

调用的时候:

NSString *md5Str = [NSString
md5:@"6688Dubai"];

NSLog(@"---加密之后--%@",md5Str);//生产32位的字符串
