Cant stop AVAudioPlayer from playing - iphone

Question

Here is my code
AppDelegate.m
I use this code to start AVAudioPlayer. It works fine.
#import "AppDelegate.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
resourcePath = [resourcePath stringByAppendingString:#"/Helloween.mp3"];
NSLog(#"Path to play: %#", resourcePath);
NSError* err;
//Initialize our player pointing to the path to our resource
backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:resourcePath] error:&err];
if( err ){
//bail!
NSLog(#"Failed with reason: %#", [err localizedDescription]);
}
else{
//set our delegate and begin playback
backgroundMusic.delegate = self;
[backgroundMusic play];
backgroundMusic.numberOfLoops = -1;
backgroundMusic.currentTime = 0;
backgroundMusic.volume = 1.0;
}
// Override point for customization after application launch.
return YES;
}
In AppDelegate.h I add framework and AVAudioPlayer
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#interface AppDelegate : UIResponder <UIApplicationDelegate> {
AVAudioPlayer *backgroundMusic;
}
#property(nonatomic,retain) AVAudioPlayer *backgroundMusic;
#property (strong, nonatomic) UIWindow *window;
#end
In ViewController.m i also add framework AVFoundation and import AppDelegate.h
#import "ViewController.h"
#import <QuartzCore/QuartzCore.h>
#import <CoreData/CoreData.h>
#define fName #"data.plist"
#define kNames #"data.plist"
#import <AVFoundation/AVFoundation.h>
#import "AppDelegate.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize backgroundMusic;
-(IBAction)stopMusic:(id)sender {
AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[appDelegate.backgroundMusic stop];
}
- (void)viewDidLoad
{
[super viewDidLoad];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//set the position of the button
button.frame = CGRectMake(100, 100, 20, 20);
button.backgroundColor = [UIColor whiteColor];
[button addTarget:self action:#selector(stopMusic:) forControlEvents:UIControlEventTouchUpInside];
//add the button to the view
[self.view addSubview:button];
ViewController.h
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import <CoreData/CoreData.h>
#define kNames #"data.plist"
#import <AVFoundation/AVFoundation.h>
#interface ViewController : UIViewController <AVAudioPlayerDelegate> {
AVAudioPlayer *backgroundMusic;
}
I need stop the AudioPlayer with button.

Answer 1

First, add UIButton to the UIView like this:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//set the position of the button
button.frame = CGRectMake(0, 0, 0, 0);
[button addTarget:self action:#selector(yourMethod:) forControlEvents:UIControlEventTouchUpInside];
//add the button to the view
[self.view addSubview:button];
Then,
-(IBAction)yourMethod:(id)sender {
[backgroundMusic stop];
}
After your done with the button, you can remove it via [button removeFromSuperView];
I think, something like that should work :) Please ask if your having problem with my answer.
