ios - segue PFObject 无法识别的选择器

Question

当我尝试将 PFObject 传递给 detailVC 并按下 tableView 中的单元格时，出现错误(见下文)。正如我所见，我做对了。

我正在加载 timeLineData 数组中的对象并使用 Storyboard NavigationController。我还使用 2 个查询在 UISearchBar 中获取名字和姓氏。

+[PFObject parseClassName]: unrecognized selector sent to class

我使用异常断点来查找错误，它给了我这个:

Answer 1

要解决这个错误，你应该在你的子类中像这样在.m文件中实现这两个方法

+ (void)load
{
    [self registerSubclass];
}

+(NSString *)parseClassName
{
    return @"YOUR CLASS NAME HERE";
}

然后像这样在.h文件中声明它们

+(NSString *)parseClassName;
+(vendor *)createVendorWithObject:(PFObject *)object;
