用显示的图像逐个播放声音

Question

我有10个图像文件和声音文件，当我显示“a.png”时，我想播放“a.mp3”。然后当我点击“下一步”按钮时，显示“b.png”并播放“b.mp3”。我该如何解决这个问题？

Answer 1

要播放声音，请使用此 在.h文件中输入以下内容： AVAudioPlayer * theaudio;

这个在你的.m文件中，当你想播放音乐时 NSString * path = [[NSBundle mainBundle] pathForResource：@“nameofmusicfile”ofType：@“mp3”]; theaudio = [[AVAudioPlayer alloc] initWithContentsOfURL：[NSURL fileURLWithPath：path] error：NULL]; [路径发布]; [theaudio play]; 停止它，使用[theaudio停止];

显示图像使用UIImageView * i;

i = [[UIImageView alloc] initWithImage：[UIImage imageNamed：@“image.png”]];

把它放在 - [view addSubview：i]; 移动它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];}
