如何推送视图,返回并返回视图？

Question

我想构建一个用于在iPhone上播放本地音频文件的应用程序但我仍然坚持使用我的一些代码.我想知道如何推送视图,回到uitableviewcontroller并使用一个按钮(如媒体播放器中的"NOW PLAYING"按钮)返回视图,而不会将任何新字符串推入其中.

谢谢

我应该从我的代码中更改什么？

在uitableviewcontroller ..

    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath
    *)indexPath  {  
selectedSong = [directoryContent objectAtIndex:indexPath.row];  
NSString *storyLin = [[directoryContent objectAtIndex:[indexPath row]] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];  
patch = [NSString stringWithFormat:@"/%@", storyLin];


        myDetViewCont = [[mPlayerViewController alloc] initWithNibName:@"mPlayerViewController" bundle:nil];    
myDetViewCont.myProgLang = selectedSong; // assigning the correct value to the variable inside DetailViewController
        [self.navigationController pushViewController:myDetViewCont animated:YES];
        [myDetViewCont release]; // releasing controller from the memory

    }

在mPlayerViewController.m中

-(IBAction) backtoplayer{
    myDetViewCont = [[mPlayerViewController alloc] initWithNibName:@"mPlayerViewController" bundle:nil];
}

Answer 1

如果您已将视图推送到导航控制器,只需将其弹出以查看下方的视图.

也就是说,您推送的视图myDetViewCont应该只在backtoplayer通话中弹出.

- (IBAction)backToPlayer:(id)sender {
    [self.navigationController popViewControllerAnimated:YES];
}
