iPhone - vibrate 5 times?

In my application I want to be able to vibrate for a few seconds to alert the user something is taking place.

I have used the following code:

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

And this works as in it will vibrate once.

However I want to be able to vibrate 5 times, not continuously or anything I just want to be able to vibrate once, stop, vibrate again, stop and so on, is this pos开发者_StackOverflowsible and acceptable by Apple via the app store?

That's currently the only method you can cause the phone to vibrate. But you could call that function 5 times!

You can do something like this..

Create an Integer. Create a 1 second timer. Hit a function every 1 second and make the phone vibrate while increasing the integer by 1. If the integer hits 5 kill the timer.

Doing it this way allows you to put a little space between vibrations so it will last as long as you'd like.

in your .h file

int vibrateCount;
NSTimer * vibrateTimer;

@property(nonatomic,assign)int vibrateCount;
@property (nonatomic, retain)NSTimer * vibrateTimer;

in your .m file

@synthesize vibrateCount,vibrateTimer;

//in viewDidLoad
vibrateCount = 0;

//put this where ever you want to start your vibrating
vibrateTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(vibratePhone) userInfo:nil repeats:YES];


-(void)vibratePhone {
vibrateCount = vibrateCount +1;

if(vibrateCount <= 5) {
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
else {

      //vibrated 5 times already kill timer and stop vibrating
      [vibrateTimer invalidate];

   }
}
