Question

我正在使用以下代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.

pushcome=NO;

pushcome=[self registerForPushNotification:launchOptions];


[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
 return YES;
}

以下代码用于接收推送：

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
NSLog(@"BACK GROUND MODE PUSH");
if([userInfo[@"aps"][@"content-available"] intValue]== 1) //it's the silent notification
{

    [self saveInUserDefault];

 stkaudioPlayer = [[STKAudioPlayer alloc]init]; //player initialize

    //Save audio url
    NSString *str= [userInfo valueForKey:@"AudioURL"];
    [[NSUserDefaults standardUserDefaults]setObject:str forKey:@"forUrl"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    // for Playing an audio using 'Avplayer' ==>
NSString *finalUrl = [NSString stringWithFormat:@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"forUrl"]];
    NSURL *url = [NSURL URLWithString:finalUrl];
    playerItem = [AVPlayerItem playerItemWithURL:url];
    player = [AVPlayer playerWithPlayerItem:playerItem];
    player = [AVPlayer playerWithURL:url];
    [player play];
    // <===
    completionHandler(UIBackgroundFetchResultNewData);

NSLog(@"==Hi, I am from silent Notification ========%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"forUrl"]);
    return;
}
else
{

    NSLog(@"User ... %@",userInfo);
        return;
}
}

我收到以下错误： -

[0x37fd8000]＆gt; aurioc＆gt; 807：失败：'！int'（启用2，outf＆lt; 2 ch，44100 Hz，Int16，inter＆gt; inf＆lt; 2 ch，0 Hz，Float32，非inter＆gt;

用于推送通知声音您需要使用此代码

Private Sub CommandButtonRemoveSelectedProjects_Click()

Dim selectioncount As Long
selectioncount = ListBoxProjectsToRemove.Selected(i)

Set TxtRng = ActiveWorkbook.Sheets("VBA_Data").Range("AY1")

For i = 0 To ListBoxProjectsToRemove.ListCount - 1
If ListBoxProjectsToRemove.Selected(i) Then
    SelectedItemText = ListBoxProjectsToRemove.List(i)
End If
Next i

TxtRng.Value = SelectedItemText

End Sub

在ios中收到静音推送通知后无法播放音频？
