Vibrating your device makes a huge impact on your app wether the user did something wrong and your warning them or there playing a game and the device vibrates on the users input to the game which makes your apps more exciting and more enjoyable. Untested by me. But another fellow coder at another site said it works.... The code ViewController.h -(IBAction)Vibrate; ViewController.m #import "ViewController.h" #import "AudioToolbox/AudioToolbox.h" @implementation ViewController -(IBAction)Vibrate { AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); }

Hmmm where would we add this in to xcode?

Brilliant tip, could this be integrated into a quiz if they got the wrong answer?

I bet it can... Now we just need some smart person to come by and let us all know what the practical applications would be and the way to implement. But your quizz idea is a great one. Buzzz Buzzz wrong answer!!!!

I like it!

ok I found where he got it from. he sent me the link... Strange name..... http://www.geekylemon.com/WEBPROTECT-xcodevibratedevice.htm

If you want the phone to vibrate when a user taps an incorrect answer on a quiz you could try inserting this into the showIncorrect method on BT_screen_quiz.m I'll try it some other day, I'm really tired right now. If someone want to try it let us know if it worked. =)

sweet find bakakos!

Quicker than those. Be sure AudioToolbox is included in the Frameworks To vibrate when wrong, in the BT_screen-quiz.m add #import <AudioToolbox/AudioToolbox.h> at the top, then scroll down to find (void)answerclick below the part where it says "answer wrong" and play sound, add //Vibrate iphone AudioServicesPlaySystemSound (kSystemSoundID_Vibrate); Thats it. This can be added elsewhere following the same steps. Only works on iPhone

Fabulous I will put this in my next app jbrzensk This site is evolving fast Quick question - do you think user would find this a fun part of quiz if they got wrong or would you it be an annoyance, and does it run down battery

Works perfectly! Good work jbrzensk

Sorry, clicked refresh

Also got the vibrate to work! Thanks jbrzensk!

What about having the device vibrate when you are using the map plugin and you get near one of the pushpins on you map? I posted a question earlier asking if anyone new how to add alerts to the map function but vibrate would work just fine. Any ideas how to make this work ? Thanks, rob

There is a sample code from apple called "regions" or something like that, that shows how to set up geofencing and regions and how to set up different distances and then trigger alerts. A lot more work than just adding a vibrate call.

Hi Jared - thanks for putting this together. I'm trying to incorporate this into 1.5 app. On BT_screen_quiz.m (line 1063) I have this: }else{ //answer was incorrect //do we play sound effect? if([[BT_strings getJsonPropertyValue:self.screenData.jsonVars:@"quizSoundEffectFileNameIncorrect":@""] length] > 3){ [appDelegate playSoundEffect:[BT_strings getJsonPropertyValue:self.screenData.jsonVars:@"quizSoundEffectFileNameIncorrect":@""]]; } I tried to replace it and add it directly below with the snippet above, but got a 'fail' message. Can you offer any insight to why this may not have worked? Think it is a 1.5 issue? I have CoreAudio.framework - perhaps I'm missing the AudioToolbox. Where could I find that? Thanks!

Right below that last parenthesis, in your example above, I have added the following: //Vibrate iPhone AudioServicesPlaySystemSound (kSystemSoundID_Vibrate); Don't replace anything, just add this little bit of code. I used 1.5 and works perfect. At the top of this file, with all the other imports, add #import "AudioToolbox/AudioToolbox.h" And to add the library, on the main window?, when you select the summary for your app, at the bottom under the icons and splash screens, is a section called "linked frameworks and libraries" Click the + and scroll to find AudioToolboxFramework

Thank you Jared! That did the trick! Thank you all for sharing!
