avaudioplayer

问题 I use a code for playing a .caf audio file, the same code works good in an iPhone 4s and an iPad 2 but doesn't play at all in a iPhone 5... this is the code: -(IBAction)checkSound:(id)sender { NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/Lunatic.caf", [[NSBundle mainBundle] resourcePath]]]; NSLog(@"%@",url); NSError *error; self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; self.audioPlayer.numberOfLoops = 0; self.audioPlayer.volume = 1;

问题 I am trying to create a simple Soundboard in Swift with a Collection View, each button representing a sound that can be played. The structure is as follows (I know, it is probably not the smartest way to do it, but it worked earlier until I added some more sounds): I have a SoundFiles.swift with the SoundFiles class, which I declared static let shared = SoundFiles() It contains two arrays let soundfiles: [String] = ["example_bla"] let soundnames: [String] = ["example bla"] as well as var

问题 To organize things , I decided to create a class called SoundPlayer where will run all audio files from my app. (This would avoid having many duplicate codes) SoundPlayer.h #import <Foundation/Foundation.h> #import <AVFoundation/AVFoundation.h> #include <AudioToolbox/AudioToolbox.h> @interface SoundPlayer : NSObject <AVAudioPlayerDelegate> @property (strong,nonatomic) AVAudioPlayer *backgroundMusicPlayer; -(void)PlaySound:(NSString*)name extension:(NSString*)ext loops:(int)val; @end

问题 We have a VOIP application, that records and plays audio. As such, we are using PlayAndRecord (kAudioSessionCategory_PlayAndRecord) audio session category. So far, we have used it successfully with iPhone 4/4s/5 with both iOS 6 and iOS 7 where call audio and tones played clearly and were audible. However, with iPhone 5s, we observed that both the call audio and tones sound robotic/garbled in speaker mode. When using earpiece/bluetooth/headset, sound is clear and audible. iOS Version used with

问题 I currently have an AVQueuePlayer playing a few .aif files in sequence. As it goes through each audio I want to perform an action related to that specific sound (for example changing an imageview's uiimage). My problem is setting the NSNotification correctly. I've set it to notify me when the queue finished with the last object, but I'm having trouble receiving an a notification for each current item. Here is what I have: //Setting Up My Queue List yellowVoice = [[AVPlayerItem alloc]

问题 I am trying to build a soundboard into an app and have figured out an efficient way of using tags to control playing the sounds. However I am now trying to integrate a pause button that can be used with the .stop() method on the AVAudioPlayer however I get an error with my current code: EXC_BAD_ACCESS This is what I am using at the moment, any ideas? import UIKit import AVFoundation let soundFilenames = ["sound","sound2","sound3"] var audioPlayers = [AVAudioPlayer]() class

问题 I have 6 sounds on one view. However I want it so that I can play more than one at once, So you tap sound 1 (sound 1 is playing) then sound 2 plays. while sound 1 is still playing. But at the moment I press sound 1 (sound 1 plays), press sound 2 (sound 2 plays, but sound 1 stops) Here is the code for the audio part. - (IBAction)oneSound:(id)sender; { NSString *path = [[NSBundle mainBundle] pathForResource:@"1" ofType:@"wav"]; if (theAudio) [theAudio release]; theAudio = [[AVAudioPlayer alloc]

问题 This question already has answers here : How to get audio to play at time from NSDatePicker? (2 answers) Closed 4 years ago . I'm creating a project which requires the user to be able to set a sound to play at a specific time and I'm currently doing that with local notification. I would like to change that to use AVAudioPlayer , and I was wondering, what would be the best approach? The objects I've got at the moment are a NSDatePicker and a stringFromDate string. My aim is to create an alarm

问题 I have a UIButton that when touched plays an audio file. At the moment touching the button twice in succession plays the audio file twice instead of stopping it. I'm looking to have the second click stop the audio file and not play a second instance. any suggestions would be very much appreciated. thanks -(IBAction) buttonNoisePlay { NSString *pathsoundFile = [[NSBundle mainBundle] pathForResource:@"noise" ofType:@"mp4"]; sound = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL

问题 Hi guys ive been trying to find a way to mute and unmute (that is play audio) via Objective-C in-code, regardless of whether the app is in mute mode or not (physical mute toggled) I see Instagram does that, where you can press the mute icon even if your phone is mute, and it will play video audio. 回答1: You want to look at audio session categories With this code you can play audio when the Ring/Silent switch to silent. NSError *setCategoryError = nil; BOOL success = [[AVAudioSession
