Iphone uitableview单元格中的自定义删除按钮don';行不通
我使用包含Rezervacija对象的filteredReservations数组创建了tableView。 我添加了自定义按钮“board”,当按钮被点击时,我用alert视图请求确认,然后将请求发送到服务器。当收到服务器的响应时,我需要从表中删除行,从filteredReservations数组中删除对象。 当我删除第一行时没问题,但是在filteredReservations中,而不是在Rezervacija对象中,我得到了UIButton对象!我不知道怎么做:) 代码:Iphone uitableview单元格中的自定义删除按钮don';行不通,iphone,objective-c,ios,uitableview,Iphone,Objective C,Ios,Uitableview,我使用包含Rezervacija对象的filteredReservations数组创建了tableView。 我添加了自定义按钮“board”,当按钮被点击时,我用alert视图请求确认,然后将请求发送到服务器。当收到服务器的响应时,我需要从表中删除行,从filteredReservations数组中删除对象。 当我删除第一行时没问题,但是在filteredReservations中,而不是在Rezervacija对象中,我得到了UIButton对象!我不知道怎么做:) 代码: - (NSInt

听起来您需要确保表视图明确知道需要显示多少过滤保留
// assuming only one section for your table view

:嘿,你可以通过这个获得“预订ID”的值
或者您可以在任何地方使用此值,就像您通过“警报框”提到的那样。对不起,我没有提到“代码剪切”中的所有方法。我已经有了同样的方法:|您应该去掉tableView的CellForRowatineXpath方法中写着“[预订释放]”的行。在这种情况下,保留是获取的,而不是创建的,因此不应在此时释放。这可能与您在表视图中只看到按钮有关,但不能保证这一点。:-)我将在明天获得物理设备时尝试此功能:)
