app安全很重要,MD5保障
// Md5.h
#import <Foundation/Foundation.h>

@implementation Md5
+(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]

新控制器中调用之前,加入头文件
调用 NSLog(@"_%@",[Md5 md5:@"1381878604212345678ios"]);
