IBACTION repeat

[maxk77]

hi, i have this ibaction:

-(IBAction)vibrate {
	AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
}

However i would like the iphone to vibrate until the user presses another button to stop the iphone vibrating. I know how to stop it vibrating i just need to know how to continue the vibrations.
thanks

Have an NSTimer call the vibrate over and over (lasting as long as the vibrate does), for example, 2 second intervals. Then call [timer invalidate]; on your other IBAction to stop the timer.

i dont really understand would you mind implementing it into my code? thanks a lot max.

-(IBAction)vibrate {
	
	AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
	
	timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(vibrateTimer) userInfo:nil repeats:YES];	
}

-(void)vibrateTimer {
	AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
}

-(IBAction)stopVibration {
	[timer invalidate], timer = nil;
	//stopVibrationHere
}

Try this, I think it should work.

it now looks like this,

#import <AudioToolbox/AudioToolbox.h>
@implementation Vibration_ButtonViewController

-(IBAction)vibrate {
	
	AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
	
	timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(vibrateTimer) userInfo:nil repeats:YES];	
}

-(void)vibrateTimer {
	AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
}

-(IBAction)stopVibration {
	[timer invalidate], timer = nil;
	//stopVibrationHere
}

and i am getting an error saying timer undeclared. What is wrong with it?

[Speed]

You have to declare timer as an NSTimer in your .h file

[maxk77]

how do i do that?

[Speed]

@interface ExampleViewController : UIViewController {

NSTimer *timer;
}

@end
