No Visible interface for 'AVAudioPlayer declares the selector initWithUrl:'

问题

I am trying to play a button click sound,also that i should be able to manage click sound along with volume button.

What i have done is Added AVFoundationFramework to project,

in .h file

#import <AVFoundation/AVAudioPlayer.h>
#import <AVFoundation/AVFoundation.h>

in .m file under button click method

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"sound1" ofType:@"mp3"];
NSURL *soundUrl = [NSURL fileURLWithPath:soundPath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithURL:soundUrl];

[player play];

but i get the above error.Any help would be appreciated.

回答1:

It's "initWithContentsOfURL:" not "initWithURL:".

As in:

AVAudioPlayer *player = [[AVAudioPlayer alloc] 
                          initWithContentsOfURL:soundUrl];
