从UITableView删除行

Question

这是我删除的代码,它工作正常,但您必须打开另一个选项卡,然后再次单击此选项卡以删除项目.由于这不是普通的UITableView,你不能只从数组中删除然后更新表.所以有人可以帮我刷新视图.此外,下面的代码段不起作用:

// Reload the view completely
if ([self isViewLoaded]) {
    self.view=nil;
    [self viewDidLoad];
}

这是我的删除代码:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    // If row is deleted, remove it from the list.
    if (editingStyle == UITableViewCellEditingStyleDelete){
        // Delete song from list & disc \\

        //Remove from arrays
        [self.Writer removeObjectAtIndex:[indexPath row]];
        [self.Book removeObjectAtIndex:[indexPath row]];
        [self.BookImageId removeObjectAtIndex:[indexPath row]];

        NSString *TempWriter = [self.ArtistNamesArray componentsJoinedByString:@","];
        NSString *TempBook = [self.SongNamesArray componentsJoinedByString:@","];
        NSString *TempBookImageId = [self.YoutubeIDSArray componentsJoinedByString:@","];

        TempWriter = [TempWriter substringToIndex:[TempArtistNames length] - 1];
        TempBook = [TempBook substringToIndex:[TempSongNames length] - 1];
        TempBookImageId = [TempBookImageId substringToIndex:[TempYouTube length] - 1];


        //Save Details
        [[NSUserDefaults standardUserDefaults] setValue:[NSString stringWithFormat:@"%@,", TempBook] forKey:@"BookName"];
        [[NSUserDefaults standardUserDefaults] setValue:[NSString stringWithFormat:@"%@,", TempWriter] forKey:@"WriterName"];
        [[NSUserDefaults standardUserDefaults] setValue:[NSString stringWithFormat:@"%@,", TempBookImageId] forKey:@"ImageId"];
        [[NSUserDefaults standardUserDefaults] synchronize];

    }


}

我的ViewWillAppear代码是:

- (void) viewWillAppear: (BOOL) animated
{
    // Reload the view completely
    if ([self isViewLoaded]) {
        self.view=nil;
        [self viewDidLoad];
    }

}

感谢所有有帮助的人

好吧,您需要调用reloadData或- deleteRowsAtIndexPaths:withRowAnimation : .
