In fact Apple have stated that there is no way to obtain the positioning of the mute switch and have stated that this is not a bug but an intentional change. 4 | 5 | However RBDMuteSwitch is a simple, small and easy to use component that takes minutes to integrate, and will even work under previous versions of iOS. 6 | 7 | A sample project is included 8 | 9 | To integrate: 10 | 11 | Include RBDMuteSwitch.h, RBDMuteSwitch.m and detection.aiff to your app 12 | 13 | Add the following to the header file where you wish to detect the mute switch 14 | 15 | #import "RBDMuteSwitch.h" 16 | 17 | to your interface declaration add the RBDMuteSwitchDelegate 18 | 19 | @interface MainViewController : UIViewController 20 | 21 | To your implementation you can call the detection routine 22 | 23 | [[RBDMuteSwitch sharedInstance] setDelegate:self]; 24 | [[RBDMuteSwitch sharedInstance] detectMuteSwitch]; 25 | 26 | then add the isMuted: delegate method 27 | 28 | - (void)isMuted:(BOOL)muted { 29 | if (muted) { 30 | NSLog("Muted"); 31 | } 32 | else { 33 | NSLog("Not Muted"); 34 | } 35 | } -------------------------------------------------------------------------------- /RBDMuteSwitchExample/RBDMuteSwitchExample-Info.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | CFBundleDevelopmentRegion 6 | en 7 | CFBundleDisplayName 8 | ${PRODUCT_NAME} 9 | CFBundleExecutable 10 | ${EXECUTABLE_NAME} 11 | CFBundleIdentifier 12 | com.rbdsolutions.${PRODUCT_NAME:rfc1034identifier} 13 | CFBundleInfoDictionaryVersion 14 | 6.0 15 | CFBundleName 16 | ${PRODUCT_NAME} 17 | CFBundlePackageType 18 | APPL 19 | CFBundleShortVersionString 20 | 1.0 21 | CFBundleSignature 22 | ???? 23 | CFBundleVersion 24 | 1.0 25 | LSRequiresIPhoneOS 26 | 27 | UIRequiredDeviceCapabilities 28 | 29 | armv7 30 | 31 | UISupportedInterfaceOrientations 32 | 33 | UIInterfaceOrientationPortrait 34 | UIInterfaceOrientationLandscapeLeft 35 | UIInterfaceOrientationLandscapeRight 36 | 37 | UISupportedInterfaceOrientations~ipad 38 | 39 | UIInterfaceOrientationPortrait 40 | UIInterfaceOrientationPortraitUpsideDown 41 | UIInterfaceOrientationLandscapeLeft 42 | UIInterfaceOrientationLandscapeRight 43 | 44 | 45 | 46 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Copyright (c) 2012, Richard Hyland http://www.richardhyland.com 2 | All rights reserved. 3 | 4 | Redistribution and use in source and binary forms, with or without 5 | modification, are permitted provided that the following conditions are met: 6 | 1.
