Hello I have a problem with my timer and I don't understand where is the problem my problem is at every milesecunds or seconds my timer disappear and appear i don't understand why :
- (void)viewDidLoad {
[super viewDidLoad];
self.BtnA.transform = CGAffineTransformMakeRotation( M_PI );
_timer = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:#selector(substractTime) userInfo:nil repeats:YES];
[self reset:nil];
}
- (IBAction)touchBtnA:(id)sender {
if (enabledA) {
[self.BtnA setEnabled:NO];
[self.BtnB setEnabled:YES];
enabledA = NO;
enabledB = YES;
[self.BtnA setAlpha:0.33];
[self.BtnB setAlpha:1.0];
} else {
[self.BtnA setEnabled:YES];
[self.BtnB setEnabled:NO];
enabledA = YES;
enabledB = NO;
[self.BtnB setAlpha:0.33];
[self.BtnA setAlpha:1.0];
}
}
- (IBAction)touchBtnB:(id)sender {
if (enabledB) {
[self.BtnB setEnabled:NO];

[self.BtnB setAlpha:1.0];
}
}

}
Thanks all for feature help.
You should know that NSTimer doesn't grant you absolute accuracy of repeating interval (1.1 in your case) of invoking selector. In other words, you should count difference between current and previous selector calls, that will be exact interval

I am developing a learning app for preschool kids. This is my code:
numbersStoreArray = [[NSMutableArray alloc]initWithObjects:#"1.png",#"2.png",#"3.png",#"4.png",#"5.png",#"6.png",#"7.png",#"8.png",#"9.png",#"10.png", nil];
commonFunctionObject = [[SpeechCommonFunctions alloc]init];
commonFunctionObject.isRecordComplete = NO;
counter = 0;
isMicPresent = YES;
_confirmationPopupView.hidden = true;
[NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:#selector(repeatActionFire) userInfo:nil repeats:NO];
}
-(void)repeatActionFire
{
if(counter >= numbersStoreArray.count)
{
NSLog(#"finished");
[_numbersShowImageView removeFromSuperview];
[_speakerOrMicImageView removeFromSuperview];
UIImageView *congratzView = [[UIImageView alloc]initWithFrame:self.view.frame];
congratzView.image = [UIImage imageNamed:#""];
[self.view addSubview:congratzView];
}
else
{
[commonFunctionObject textToSpeechAction:numbersStoreArray :counter :_numbersShowImageView :_speakerOrMicImageView :isMicPresent];
[NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:#selector(ActionToCkeckRecordCompletion) userInfo:nil repeats:YES];
}
}
-(void)ActionToCkeckRecordCompletion
{
if(commonFunctionObject.isRecordComplete)
{
_confirmationPopupView.hidden = false;
}
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)playButtonAction:(id)sender
{
[commonFunctionObject recordPlayAction];
}
- (IBAction)nextButtonAction:(id)sender
{
counter+=1;
_confirmationPopupView.hidden = true;
commonFunctionObject.isRecordComplete = NO;
if(commonFunctionObject.player.playing){[commonFunctionObject.player stop];}
[self repeatActionFire];
}
- (IBAction)retryButtonAction:(id)sender
{
_confirmationPopupView.hidden = true;
commonFunctionObject.isRecordComplete = NO;
if(commonFunctionObject.player.playing){[commonFunctionObject.player stop];}
[self repeatActionFire];
}
After completion of this, this entry to the repeatActionFire and show finished. My question is: I need to display the congratulation view after the completion of the game and need to use two buttons.
Buttons for:
to reach the homepage
to retry the game.
How to do this?
Pressing a button in my iOS app calls the changeLanguage method.
- (void)changeLanguage:(BOOL) isMyanmar {
if (hasRun == YES) {
return;
}
hasRun = YES;
NSUserDefaults * userdefaults = [NSUserDefaults standardUserDefaults];
[userdefaults setBool:isMyanmar forKey:#"myanmar"];
[userdefaults synchronize];
[self updateCurrentLanguageText];
if ([self isMyanmar]) {
[self changeLanguageFlag:#"MyanmarFlagBig"];
} else {
[self changeLanguageFlag:#"UnitedKingdomFlagBig"];
}
[self countDown];
}
- (void)countDown {
static int i = 3;
if (i == 3) {
i--;
UIImage *three = [UIImage imageNamed:#"Three"];
countDownFlag = [[UIImageView alloc] initWithImage:three];
countDownFlag.frame = CGRectMake(0, 370, countDownFlag.frame.size.width, countDownFlag.frame.size.height);
countDownFlag.center = CGPointMake(width / 2, countDownFlag.center.y);
[self.view addSubview:countDownFlag];
[self performSelector:#selector(countDown) withObject:nil afterDelay:0.5];
} else if (i == 2) {
i--;
UIImage *two = [UIImage imageNamed:#"Two"];
[countDownFlag setImage:two];
[self performSelector:#selector(countDown) withObject:nil afterDelay:0.5];
} else if (i == 1) {
i--;
UIImage *one = [UIImage imageNamed:#"One"];
[countDownFlag setImage:one];
[self performSelector:#selector(countDown) withObject:nil afterDelay:0.5];
} else {
[self dismissViewControllerAnimated:YES completion:nil];
}
}
The method used to run fine but recently is having trouble with threading at [self countDown].
What could be causing the problem and how can I resolve this?
Edit:
How changeLanguage gets called
Two methods call this method:
- (void)changeLanguageToEnglish {
[self changeLanguage:false];
}
- (void)changeLanguageToMyanmar {
[self changeLanguage:true];
}
How the button calls the methods:
[languageButton addTarget:self action:#selector(changeLanguageToEnglish) forControlEvents:UIControlEventTouchUpInside];

In particular, this class should hear (with microphone) an audio signal in which there are some tone with a frequency >= 18000 Hz. So I will make this: when it recognize a tone of a frequency >= 18000 Hz it should play a sound.
When I try to run the app on the device I hear the sound with a very low volume by using iPhone speaker, but when I plug the headphone I hear the sound with an high volume. I tried to run the app by using simulator and when I use simulator it works nice. Why's that? Can you help me to fix this class?
PS: to detect the frequency of sounds I'm using pitch detector.
I solved it, I post here the code:

I just put the initializer of the AVAudioPlayer into method setTextInLabel and it works.
Thank you!
I am new to App Development, sorry if I am asking silly questions :(
I am developing a Quiz App. Whenever I give a right or wrong answer, an image appears with right or wrong answer result, however it stays for a few seconds, but after that - it does not continue with the next question. It just shows my background images with buttons. How can I set a code, that it goes straight to a new question, when the result image is gone.
I will be very thankful for your help.
I just want that after the Result-image closes, the quiz continues with the next question.
This is the code i have setup in Game.m file.
-(void)RightAnswer{
ScoreNumber = ScoreNumber + 1;
Score.text = [NSString stringWithFormat:#"%i", ScoreNumber];
Answer1.hidden = YES;
Answer2.hidden = YES;
Answer3.hidden = YES;
CategorySelected.hidden = NO;
Next.hidden = NO;
imageQuestion.hidden = YES;
Results.hidden = NO;
Results.image = [UIImage imageNamed:#"right.png"]; [self performSelector:#selector(Results) withObject:nil afterDelay:2.0];
GameInProgress = YES;
}
-(void)WrongAnswer{
LivesNumber = LivesNumber - 1;
Lives.text = [NSString stringWithFormat:#"%i", LivesNumber];
Answer1.hidden = YES;
Answer2.hidden = YES;
Answer3.hidden = YES;
imageQuestion.hidden = YES;
CategorySelected.hidden = NO;
Next.hidden = NO;
Results.hidden = NO;
Results.image = [UIImage imageNamed:#"wrong.png"];[self performSelector:#selector(Results) withObject:nil afterDelay:2.0];
GameInProgress = YES;
if(LivesNumber ==0) {
Results.image = [UIImage imageNamed:#"gameover.png"];
GameInProgress = NO;
Exit.hidden = NO;
}
-(void)RightAnswer{
ScoreNumber = ScoreNumber + 1;
Score.text = [NSString stringWithFormat:#"%i", ScoreNumber];
Answer1.hidden = YES;
Answer2.hidden = YES;
Answer3.hidden = YES;
Answer1Correct ==YES;
CategorySelected.hidden = NO;
Next.hidden = NO;
imageQuestion.hidden = YES;
Results.hidden = NO;
Results.image = [UIImage imageNamed:#"right.png"]; [self performSelector:#selector(Results) withObject:nil afterDelay:2.0];
GameInProgress = YES;
}
I think the issue is that you never set Answer1Correct to anything. so if you add Answer1Correct ==YES to the correct answer method and Answer1Correct ==NO to the wrong method then it should work
-(void)Results{ // just change formate of answer.
Results.hidden = YES;
}
-(IBAction)Answer1: (id) sender{
if (Answer1Correct ==YES) {
[self RightAnswer];
}else{
[self WrongAnswer];
}
}
-(IBAction)Answer2: (id) sender{
if (Answer2Correct ==YES) {
[self RightAnswer];
}
else{
[self WrongAnswer];
}
}
-(IBAction)Answer3: (id) sender{
if (Answer3Correct ==YES) {
[self RightAnswer];
}
else{
[self WrongAnswer];
}
}
i may be wrong here but I think you need an if to the else.
But I could be wrong.
if(LivesNumber ==0) {
Results.image = [UIImage imageNamed:#"gameover.png"];
GameInProgress = NO;
Exit.hidden = NO;
}else{
donextcard();
}
if you want to know how to make that function we would need to see more of the code.
I’m building a reaction test that requires the user to tap on the target dot, while other non-target dots come down. It works most of the time but sometimes after tapping on a target dot it will display several other dots with weird behavior. I’ve been looking at the code for days and I can’t find the problem. Does anyone have any suggestions?
