正确的方式添加一个声音到UIAlertView [英] Correct way to add a sound to UIAlertView

问题描述

向UIAlertView添加声音的最正确方法是什么？

我应该将其子类化，然后在视图出现时播放系统声音？

还是会更正确，不是子类，而是调用一个单独的方法来播放声音时出现？

任何人都可以推荐一个比UIAlertView更有声音和外观的控件。

解决方案

c> AVAudioPlayer 下面的代码： -

在.h文件中设置 UIAlertView 的dalagete like： -

  @interface ViewController：UIViewController< UIAlertViewDelegate> 
   
  in .m file 
 
 
 
   - （void）viewDidLoad 
 {
 [super viewDidLoad]; 
 NSURL * url = [NSURL fileURLWithPath：[NSString stringWithFormat：@％@ / foo.mp3，[[NSBundle mainBundle] resourcePath]]]; 
 
 NSError * error; 
 UIAlertView * alert = [[UIAlertView alloc] initWithTitle：@Titlemessage：@messagedelegate：self cancelButtonTitle：@OkotherButtonTitles：nil]; 
 audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL：url error：& error]; 
 audioPlayer.numberOfLoops = 1; 
 [audioPlayer play]; 
 [alert show]; 
} 
  - （void）alertView：（UIAlertView *）alertView clickedButtonAtIndex：（NSInteger）buttonIndex {
 if（buttonIndex == 0）{
 [audioPlayer stop]; 
 
} 
 
} 
  
  EDIT  
 
 
 
 注意：不要忘记添加 AVAudio框架如果你想播放声音直到没有按下 UIAlertView 的Button，然后设置 audioPlayer.numberOfLoops = -1;  p> 
What is the most correct way to add a sound to a UIAlertView?

Should I subclass it and then play a system sound when the view appears?

Or would it be more correct, not to subclass but instead call a separate method to play a sound when it appears?

Can anyone recommend a control that plays sound and looks prettier than UIAlertView?
解决方案
you can achieve this by using AVAudioPlayer bellow code:-

Set dalagete of UIAlertView in .h file like:-
@interface ViewController : UIViewController <UIAlertViewDelegate>
in .m file 
- (void)viewDidLoad
{
    [super viewDidLoad];
    NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/foo.mp3", [[NSBundle mainBundle] resourcePath]]];

    NSError *error;
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title" message:@"message" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; 
    audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
    audioPlayer.numberOfLoops = 1;
    [audioPlayer play];
    [alert show]; 
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if (buttonIndex==0) {
        [audioPlayer stop];

    }

}
EDIT

NOTE:- Do not forget to Add AVAudio framework And if you wish to sound playing till not press Button of UIAlertView then set audioPlayer.numberOfLoops = -1;
