ios - Accessing the iPhone SMS file

Question

I try to access sms db file in xcode but fail. I know its path that is "/private/var/mobile/Library/SMS/sms.db" When i try to access. the file read no permission error occur.

Is any way to access sms db file or change its permission in xcode. Thanks in advance. The code which i try on iphone jailbroken is

NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *path = @"/var/mobile/Library/SMS/sms.db";
NSError *error;
NSArray *content = [fileManager contentsOfDirectoryAtPath:path error:&error];
NSLog(@"%@", error);
NSLog(@"Content: %@", content);
if ([fileManager isReadableFileAtPath:path]) {
    NSLog(@"");
    NSLog(@"ReadAble");
}
else {
    NSLog(@"Not readable");
}
if ([fileManager fileExistsAtPath:path])
    NSLog(@"File Exist");
else
NSLog(@"No");

further when i try to call_history.db file . it is accessible. but sms.db not.

No, there is currently no way to do so on stock iOS. It is restricted by the framework itself, and thus not possible as it is.

On a jailbroken iPhone this is possible, but it will perhaps only work on the same jailbreak of the very same version.

EDIT: One other solution, which won't pass to AppStore, is to find some exploitable bug in the iOS (there must be a lot, check out how jailbreaks are done) to gain root access in your app. Then you would be able to access the data you want on a non-jailbroken iPhone. But it will probably only work on the version on which you developed it.
