UIButtons event Touch up Inside not work properly? - iphone

Question

My question is little abmigious ,thats why I posted all my code,so I request to every one please test all this code before giving me the Answer.Thanx
In my application i create all UIButtons programmatically and then save all these UIButtons in NSMutableArray. Here is my code:-
-(void)button:(id)sender
{
int btnn = 0;
int spacex = 152;
int spacey=20;
int k=0;
saveBtn = [[NSMutableArray alloc] init];
for (int i=0; i<48; i++)
{
if (btnn>6)
{
spacey=spacey+25;
spacex = 152;
btnn = 0;
}
else
{
btnn++ ;
k++;
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(spacex, spacey, 25.0, 25.0);
int idx;
idx = arc4random()%[arr count];
NSString* titre1 = [arr objectAtIndex:idx];
[btn setTitle: titre1 forState: UIControlStateNormal];
[btn setTitleColor: [UIColor yellowColor] forState: UIControlStateNormal];
[btn.titleLabel setFont:[UIFont fontWithName:#"TimesNewRomanPS-BoldMT" size:22.0]];
spacex = spacex + 25;
btn.tag=k;
[btn addTarget:self action:#selector(aMethod:)forControlEvents:UIControlEventTouchUpInside];
[saveBtn addObject:btn];
[self.view addSubview:btn];
}
}
}
Now in (aMethod:) I add click sound on Each UIButton TouchUpInside event. Here is my code.
- (void)aMethod:(id)sender
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
[theAudio play];
}
Every thing work fine in start of my application , but continiously clicking the UIButtons approximatilly after 100 clicks i hear no sound of click and when i click on Next UIButtons touchup inside event its crash.Can any body help me in this issue.Thanx

Answer 1

app due to uncaught exception NSInternalInconsistencyException, reason: Could not load NIB in bundle: NSBundle </Users/moon/Library/Application Support/iPhone Simulator/4.1/Applications/3E14E5D6-4D1B-4DAC-A2B9-07667E99C399/soundtesting.app‌​> (loaded) with name secondclass
Ah, yes. What we have here is a failure to understand log messages. Your UIButton, which I can only assume pushes a new view onto the stack, is referencing a NIB that simply doesn't exist. It's a naming issue, not a button issue. Most likely, I would check for any calls to -initWithNibName: and see if your NIB really is named "secondclass.". Remember, iOS file names are CaSe SeNsITive.
//.h
...
#property (nonatomic, retain) AVAudioPlayer * player;
//.m
-(void)viewDidLoad
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
player=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
player.delegate=self;
//in MRC, use [path release];
}
-(void)someMethod:(id)sender
{
[player play];
}

The reason might me memory leak for playing same audio these many times it may fill memory use this code for playing audio
- (id)initWithNibName:(NSString*)nibName bundle:(NSBundle*)nibBundleOrNil
{
if (self = [super initWithNibName:nibName bundle:nibBundleOrNil]) {
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
theAudio = [AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:filePath] error:NULL];
}
return self;
}
- (IBAction)playSound
{
[theAudio play];
}
- (void)dealloc
{
[theAudio release];
[super dealloc];
}

You have a memory issue. When you do :
- (void)aMethod:(id)sender
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
[theAudio play];
}
1/ path is never released
2/ theAudio is never release
So you need to release theAudio in delegate method :
– audioPlayerDidFinishPlaying:successfully:
And you need to release path like this :
- (void)aMethod:(id)sender
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
[theAudio play];
[path release];
}
I think your problem should be solved.

I test your code . Changes in your aMethod following code. Though this I can get tag value.
- (void)aMethod:(id)sender
{
UIButton *btn=(UIButton *)sender;
NSLog(#"\n\n\nselectedbutton tag === %d \n\n\n",btn.tag );
NSString *path = [[NSBundle mainBundle] pathForResource:#"button-17" ofType:#"wav"];
NSURL *url = [[NSURL alloc] initFileURLWithPath:path];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPlayer play];
}
