iOS SDK Snippet: iPhone Vibration

[Cartman.]

With this iOS SDK code snippet, you will learn how to cause the iPhone to vibrate with the AudioToolbox framework and a single line of code.

Creating a vibration is simple as pie - simpler in fact. It just requires one line of code; two if you add the import line. But as simple as a one-liner is it is better to make it into a function. So here is the one liner, followed by the function. Cheers

/  NOTE: You need to import the AudioToolbox for access to the vibrate
#import <AudioToolbox/AudioToolbox.h>
*
//  The one-liner:
AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);
*
//  The function:
- (void)vibrate {
  AudioServicesPlaySystemSound (kSystemSoundID_Vibrate);
}
*
//  The call from within another method in the same class:
- (void)myMethod {
  [self vibrate];
}
