objective-c - 播放声音与显示的图像一一对应

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，当我单击“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];}
