Xcode button linking error? - ios

Question

Hey I was wondering is their any possible way I can link two actions to the same button in Xcode? I've already tried but keep getting this error: "terminating with uncaught exception of type NSException". So i'm guessing I am not able to do that? See what i'm trying to do is
make a button play a sound but that same button is also linked to starting a new round in the game. How would I go about doing this? I've currently got this going in my .m file.
#import "BullsEyeViewController.h"
#interface BullsEyeViewController ()
#end
#implementation BullsEyeViewController
{
int _currentValue;
int _targetValue;
int _score;
int _round;
}
- (IBAction)playSound:(id)sender {
SystemSoundID soundID;
NSString *buttonName=[sender currentTitle];
NSString *soundFile=[[NSBundle mainBundle]
pathForResource:buttonName ofType:#"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)
[NSURL fileURLWithPath:soundFile], &
soundID);
AudioServicesPlaySystemSound(soundID);
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self startNewGame];
[self updateLabels];
UIImage *thumbImageNormal = [UIImage
imageNamed:#"SliderThumb-Normal"];
[self.slider setThumbImage:thumbImageNormal
forState:UIControlStateNormal];
UIImage *thumbImageHighlighted = [UIImage
imageNamed:#"SliderThumb-Highlighted"];
[self.slider setThumbImage:thumbImageHighlighted
forState:UIControlStateHighlighted];
UIImage *trackLeftImage =
[[UIImage imageNamed:#"SliderTrackLeft"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 14, 0, 14)];
[self.slider setMinimumTrackImage:trackLeftImage
forState:UIControlStateNormal];
UIImage *trackRightImage =
[[UIImage imageNamed:#"SliderTrackRight"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 14, 0, 14)];
[self.slider setMaximumTrackImage:trackRightImage
forState:UIControlStateNormal];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)startNewRound
{
_round += 1;
_targetValue = 1 + arc4random_uniform(100);
_currentValue = 50;
self.slider.value = _currentValue;
}

}
- (void)updateLabels

}

- (IBAction)showAlert
{
int difference = abs(_targetValue - _currentValue);
int points = 100 - difference;
NSString *title;
if (difference == 0) {
title = #"Perfect!";
points += 100;
} else if (difference < 5) {
title = #"You almost had it!";
if (difference == 1) {
points += 50;
}
} else if (difference < 10 ) {
title = #"Pretty good!";
} else {
title = #"Not even close...";
}
_score+=points;
NSString *message = [NSString stringWithFormat:#"You scored %d points", points];
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle: title
message:message
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles: nil];
[alertView show];
}
-(IBAction)sliderMoved:(UISlider *)slider
{
_currentValue = lroundf(slider.value);
}
- (void)alertView:(UIAlertView *)alertView
didDismissWithButtonIndex:(NSInteger)buttonIndex
{
[self startNewRound];
[self updateLabels];
}
-(IBAction)startOver
{
CATransition *transition = [CATransition animation];
transition.type = kCATransitionFade;
transition.duration = 1;
transition.timingFunction = [CAMediaTimingFunction
functionWithName:kCAMediaTimingFunctionEaseOut];
[self startNewGame];
[self updateLabels];
[self.view.layer addAnimation:transition forKey:nil];
}

Some help would be greatly appreciated :)

Answer 1

Add an action like this to the button
-(IBAction)myButtonPressed:(id)sender
{
[self playSound:sender];
[self startNewRound:Sender];
}

Answer 2

Use only one action, just set a BOOL to check if you need to play the sound or not.
Example code would be:
-(IBAiction)btnPressed:(id)sender
{
if(playsound)
{
[self playSound];
playsound = NO;
}
[self startOver];
}
And then whenever you want the saund to be played again just set playsound to YES and next time user presses the button it will play the sound again
