Question

如问题中所述，我已将少量图像和声音文件添加到资源文件夹中。使用下一个和上一个按钮，图像导航工作正常。现在我需要播放与图像相关的声音。工作代码如下所示。我需要知道我需要做些什么才能让声音与图像一起播放。

我添加了audioToolbox.framework＆amp; AVFoundation.framework。我在Apple开发者网站上看过NSSound。

#import "next_previousViewController.h"

@implementation next_previousViewController

@synthesize image1, next1, next2;

NSMutableArray *list;
NSMutableArray *sound;

int state1 = 0;



/*
// The designated initializer. Override to perform setup that is required before the view is loaded.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        // Custom initialization
    }
    return self;
}
*/

/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/



// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad 
{
    list = [[NSMutableArray alloc] init];
    [list addObject:@"A.png"];
    [list addObject:@"B.png"];
    [list addObject:@"C.png"];
    [list addObject:@"D.png"];

    //[image1 setImage:[UIImage imageNamed:@"A.png"]];

    sound = [[NSMutableArray alloc] init];
    [sound addObject:@"A.mp3"];
    [sound addObject:@"B.mp3"];
    [sound addObject:@"C.mp3"];
    [sound addObject:@"D.mp3"];
    [sound addObject:@"E.mp3"];

    [super viewDidLoad];
}

-(IBAction) doNext
{
    int i, count;
    //state = 1;
    count = [list count];
    for(i = state1; i < count; i++)
    {
        [image1 setImage:[UIImage imageNamed:[list objectAtIndex:state1]]];

        //--------------------For Sound-----------------------------------

        //-----------------------------END--------------------------------


        //exit(0);

        //UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"hello" message:[NSString stringWithFormat: @"%d", state1] delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
        //[alert show];
        state1 = state1 + 1;
        break;

    }
}

-(IBAction) doPrev
{
    int i, count;
    count = [list count];
    for(i = state1; i < count; i++)
    {
        state1 = state1 - 2;
        [image1 setImage:[UIImage imageNamed:[list objectAtIndex:state1]]];
        //UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"hello" message:[NSString stringWithFormat: @"%d", state1] delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
        //[alert show];

        state1 = state1 + 1;
        break;

    }
}


// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}


- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
    [super dealloc];
}

@end

很抱歉这个问题很长。
