iOS check if application has access to microphone

In iOS7 there is no way to get the current status of microphone authorization.They have given the enum in iOS8 as AVAudioSessionRecordPermission

In iOS7 you have to request permission every time with

[[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL granted) {
        if (granted) {
            NSLog(@"Permission granted");
        }
        else {
            NSLog(@"Permission denied");
        }
    }];

The same question has been asked before but there is no such api with which you know current status as in iOS8

You can refer Check for mic permission on iOS 7 without showing prompt

Solution:

Another option is you can show the popup or ask for permission first time and save the states of user option selected in NSUserDefaults and than onwards do not ask for permission. From docs you explicitly do not need to call this if each you do not need to get the permission of user.It will automatically called by AVAudioSession first time when you try to record

Recording audio requires explicit permission from the user. The first time your app’s audio session attempts to use an audio input route while using a category that enables recording (see “Audio Session Categories”), the system automatically prompts the user for permission; alternatively, you can call requestRecordPermission: to prompt the user at a time of your choosing
