我有一个应用程序，我在我的资源文件夹中添加了3个.wav文件。然后我在这个类的didselectRowatIndexPath中获取数组中的所有3首歌曲。我将数组设置为nsstring变量。在这个nsstring变量中，我选择了它的文件路径的歌曲正在存储，我正在我的类中访问这个nsstring变量，我正在调度通知，并在其中的notification.soundname属性我设置了存储歌曲文件路径的变量。
但问题是当收到通知而没有播放特定歌曲而是播放默认通知声音时。可能是什么问题？这是我的代码。
这是我选择歌曲的课程：
- (void)viewDidLoad {
[super viewDidLoad];
//this is used to search all the song files with wav extension in the resources folder.
app = (StopSnoozeAppDelegate*)[[UIApplication sharedApplication]delegate];
soundarray = [[[NSBundle mainBundle]pathsForResourcesOfType:@".wav" inDirectory:nil]retain];
tblView.delegate = self;
tblView.dataSource = self;
}
#pragma mark - UITableView, UITableViewDataSource delegate.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [soundarray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1
reuseIdentifier:CellIdentifier] autorelease];
}
switch (indexPath.row) {
case 0:
cell.textLabel.text = [soundarray objectAtIndex:0];
break;
case 1:
cell.textLabel.text = [soundarray objectAtIndex:1];
break;
case 2:
cell.textLabel.text =[soundarray objectAtIndex:2];
break;
default:
break;
}
cell.textLabel.text = [soundarray objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
app.newsong = [soundarray objectAtIndex:indexPath.row];
[delegate selectsoundControllerReturnedsound:app.newsong forIndexPath:self.indexPathToChange];
[self.navigationController popViewControllerAnimated:YES];
}
和我正在安排通知的类我已经加入了我的app委托字符串变量，其中存储了声音文件路径。
notification.soundName = app.newsong;
但通知会显示默认通知声音。
这是用于安排通知的代码
