用顯示的圖像逐個播放聲音

Question

我有10個圖像文件和聲音文件，當我顯示「a.png」時，我想播放「a.mp3」。然後當我點擊「下一步」按鈕時，顯示「b.png」並播放「b.mp3」。我該如何解決這個問題？

Answer 1

要播放聲音，請使用此 在.h文件中輸入以下內容： AVAudioPlayer * theaudio;

這個在你的.m文件中，當你想播放音樂時 NSString * path = [[NSBundle mainBundle] pathForResource：@「nameofmusicfile」ofType：@「mp3」]; theaudio = [[AVAudioPlayer alloc] initWithContentsOfURL：[NSURL fileURLWithPath：path] error：NULL]; [路徑發佈]; [theaudio play]; 停止它，使用[theaudio停止];

顯示圖像使用UIImageView * i;

i = [[UIImageView alloc] initWithImage：[UIImage imageNamed：@「image.png」]];

把它放在 - [view addSubview：i]; 移動它i.center = CGPointMake（0.0,0.0）;

-(void) viewDidLoad;{ 


sounds = [[NSArray alloc]initWithObjects:@"a.mp3", @"b.mp3",@"c.mp3", nil]; 


imageArray = [[NSArray arrayWithObjects: 
       [UIImage imageNamed:@"a.jpg"], 
       [UIImage imageNamed:@"b.jpg"], 
       [UIImage imageNamed:@"c.jpg"], 
       nil] retain]; 
[super viewDidLoad];} 
-(IBAction) next; { 
currentSound++; 
if (currentSound >= sounds.count) currentSound = 0; 
//what kind of code play this sound////images work perpectly but sound not// 


currentImage++; 
if (currentImage >= imageArray.count) currentImage = 0; 
UIImage *img = [imageArray objectAtIndex:currentImage]; 
[imageView setImage:img];}
