Question

我有十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

-(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];}

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

当你想播放音乐时，这就在你的.m中 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 stop];

显示图像使用UIImageView * i;

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

把它穿上 - [查看addSubview：i]; 移动它i.center = CGPointMake（0.0,0.0）;

逐个播放带有显示图像的声音
