Thanks. I'll keep this thing in mind in future. But i had two questions for permission alert. One for access gallery and second for access contacts. Main thing is that i am unable to show permission alert in iOS6 device(For contacts) because my app is compatible with iOS5. — shivam, Jan 18 '13 at 09:13

It is not working. My app is closing with this issue "implicit declaration of ABAddressBookCreateWithOptions is invalid in c99" — shivam, Jan 18 '13 at 10:59

you can show this by help of ALAssetsLibrary library & ALAuthorizationStatus

ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];

    if (status != ALAuthorizationStatusAuthorized) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Message" message:@"permission alert message" delegate:nil cancelButtonTitle:@"Close" otherButtonTitles:nil, nil];
        [alert show];
    }
