Question

我正在开发一个项目，使您能够在选择了tableview中的单元格时播放声音。为了让事情变得简单，我实现了一个搜索功能。问题是，它不能正常工作。当您单击结果时，播放的声音来自原始数组，而不是新过滤的声音。我知道我的错误就在这里的某个地方，我想找一点帮助。

//Create new Sound Object
Sounds *sound = nil;
//check to see whether the normal table or search results table is being displayed and     set the Sound object from the appropriate array
if (tableView == self.searchDisplayController.searchResultsTableView) {

    sound = [filteredSoundArray objectAtIndex:indexPath.row];
}else{
    sound = [soundArray objectAtIndex:indexPath.row];
}

//Configure the cell
[[cell textLabel]setText:[sound name]];
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];

 return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSString *selectedSoundFile = [[soundArray objectAtIndex:indexPath.row]name];
NSString *path = [[NSBundle mainBundle]pathForResource:selectedSoundFile ofType:@"mp3"];


if(path){
   theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

    [self.theAudio play];
}

  if (tableView == self.searchDisplayController.searchResultsTableView) {
    theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

    [self.theAudio play];

}

}

谢谢！

更改didSelectRowAtIndexPath

中的数组

NSString *selectedSoundFile = [[soundArray objectAtIndex:indexPath.row]name];

如果您要从搜索结果中进行处理，请使用filteredSoundArray代替soundArray ..

您正在播放的条件应该从您用于在表格视图中显示的阵列中播放。但是你正在使用具有所有声音的阵列。

在didSelectRowIndexPath

中进行如下更改

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

[tableView deselectRowAtIndexPath:indexPath animated:YES];

NSString *selectedSoundFile;
if (tableView == self.searchDisplayController.searchResultsTableView) {

selectedSoundFile = [[filteredSoundArray objectAtIndex:indexPath.row]name];
}else{
selectedSoundFile = [[soundArray objectAtIndex:indexPath.row]name];
}
NSString *path = [[NSBundle mainBundle]pathForResource:selectedSoundFile ofType:@"mp3"];


if(path){
   theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

[self.theAudio play];
}
}

过滤搜索结果
