サウンドを再生する簡単なアプリ

iOSで音を鳴らすシンプルなアプリ．
StoryBoardを貼らないとあまり意味ないかもしれないけどメモ．

画像ファイルやサウンドファイルは
Supporting Filesに入っている前提．

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController {
IBOutlet UIImageView *myImageView;

}

@property AVAudioPlayer *sound;
-(IBAction)tapBtn;

@end

ViewController.m

#include <AVFoundation/AVFoundation.h>
#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(IBAction)tapBtn {
    myImageView.image = [UIImage imageNamed:@"IMG_0976.jpg"];
    
    NSString *path = [[NSBundle mainBundle] pathForResource:@"moon_river" ofType:@"m4r"];
    NSURL *url = [NSURL fileURLWithPath:path];
    
    self.sound = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
    [self.sound play];
}

@end
