当我试图将PFObject传递给detailVC并按下tableView中的单元格时，我收到错误（见下文）。
在我看来，我做得对。
我正在加载timeLineData数组中的对象并使用故事板NavigationController。我还使用2个查询来获取UISearchBar中的名字和姓氏。
+[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：

要解决此错误，您应该在.m文件
中的子类中实现这两个方法+ (void)load
{
[self registerSubclass];
}
+(NSString *)parseClassName
{
return @"YOUR CLASS NAME HERE";
}
然后在.h文件中声明它们
+(NSString *)parseClassName;
+(vendor *)createVendorWithObject:(PFObject *)object;
