ios9,daemon读取文件内容崩溃,[NSData dataWithContentsOfFile]和fread都崩溃,怎么解决

daemon进程读取我自己客户端存储的文件一直导致程序崩溃推出
在把内容从文件读取出来的第一步就回崩溃
ios8 下[NSData dataWithContentsOfFile]一直都很正常,但是在ios9下就回导致程序崩溃,我换用C代码直接读取文件内容,但是还是崩溃

 char* readFileBytes(const char *name)
{
     NSLog(@" >> >> >> read file data in c start  .. %s",name);
    FILE *fl = fopen(name, "r");
    fseek(fl, 0, SEEK_END);
    long len = ftell(fl);
    NSLog(@" >> >> >> read file %s data len %ld",name,len);
    char *ret = malloc(len);
    NSLog(@" >> >> >> read file data in c malloc");
    fseek(fl, 0, SEEK_SET);
    NSLog(@" >> >> >> read file data in c seek");
    fread(ret, sizeof(char), len, fl);
    NSLog(@" >> >> >> read file data in c fread");
    fclose(fl);
    NSLog(@" >> >> >> read file data in c return");
    return ret;
}

测试发现程序在最后fread 的时候崩溃了
我的daemon的权限是root

#ls    -lah
-rwxr-xr-x  1 root wheel 139K Oct 27 07:03 Demond*

请问是不是Ios9的安全机制导致这个问题的?这种情况怎么破啊?

崩溃日志是什么?

根本没有崩溃日志,try catch都catch不到,以为我的daemon是在启动的时候读取文件内容的,现在导致daemon在启动的一瞬间就崩溃掉了,crashreporter也说不会记录这个日志,因为not-acitonable,一会儿我贴图上来

你不要在启动时读,等启动完了过10秒再读,看看崩不崩

启动完等了10秒之后,还是回崩溃。。。。

   NSDictionary * unPackFile(NSString* filename)
{
    NSLog(@" >> >> get ziped data start");
    
    if (![[NSFileManager defaultManager] fileExistsAtPath:filename]) {
        return nil;
    }
    NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:filename error:nil];
    NSNumber *fileSize = [fileAttributes objectForKey:NSFileSize];
    NSLog(@" >> >> check file exist %@ ", fileAttributes);
    @try {
        
        NSLog(@" >> >> read file data start");
        
        NSData *zipedData = [NSData dataWithContentsOfFile:filename];
        
        NSLog(@" >> >> get ziped data 。。。 %@", filename);
        
        NSData *encryptedData = unZipData(zipedData);
        
        NSLog(@" >> >> unziped data 。。。 %@", filename);
    }
    @catch (NSException *exception) {
        NSLog(@" >> >> >> %@", exception.reason);
    }
}

下面是syslog

NSFileManager能获取文件的各种信息,但是读取的时候就会崩溃,并且
#report not saved because it is non-actionable

@snakeninny

楼主,fauxsu不起作用,你解决这个问题了吗?

fauxsu无效请问怎么解决

大神请问一下我根据狗神的文章下载的fauxsu,里面没有fauxsu和libdauxsu.dylib文件,请问一下你是在哪里在下的?
我通过一片帖子里面下载的fauxsu,里面有fauxsu和libdauxsu.dylib文件,放到$THEOS/bin/下面,执行了chmod a+x $THEOS/bin/fauxsu 然后权限还是staff
请问一下是哪里有问题吗?
我个人感觉是fauxsu的下载地址有问题,能否分享一下你的fauxsu的下载地址或者分享一个文件也行,谢过大神
